I created this Generator a while back and used it with friends to have fun creating fluff and alternate stories. One of them suggested to me that I put it online, and I thought “Hey, why not”.

Anyway, this generator was created to allow the story of additional Primarchs during the Heresy. It is a Generator with a lot of things, and may be complicated, so I decided to divide it into 5 parts, namely:

1. Early Life: The Primarch's life on his homeworld and his discovery by the Emperor.
   
2. Great Crusade: The Primarchs main campaigns during the Great Crusade. End with the Crusade and Triumph of Ulanor.
   
3. Warmaster Crusade: The Crusade under Horus's leadership, from Ulanor up to Itssvan V. By the end of it, your Primarch will be ether a loyalist or a traitor.
   
4. Horus Heresy: The main fights between the traitors and loyalists. End with the Battle of Terra and the death of Horus.
   
5. Aftermaths: The shortest part, focus on what happened to your Primarch and his Legion following the Heresy.

For this generator you'll need two things:

• Ether an online dice roller or real dices.
  
• Something to generate names, mainly for your Primarch, Legion and for the planets and systems where they'll fight.

Legion: The name of your Legion.
Number: The number of your Legion (like II or XI, for exemple)
Homeworld: The Homeworld of your Legion, where your Primarch was raised.
Primarch: Your Primarch name.
Nickname: If he has some nickname(s), like The Phoenician for Fulgrim or the Urizen for Lorgar
Modifier: During the Generator, you'll get + and -. Put the total here. It will be added to the roll that will determine if your Primarch goes traitor or stays loyal.

Of course, the rolls aren't everything, and there's always a need to add some fluff. I'll put two Primarchs as examples if it help understand how the generator work. For those two, let assume that they are the long lost Primarchs, which in this case were found and joined their brothers in the Great Crusade.

EXEMPLE #1


Legion: Storm Knights
Number: II
Homeworld: Caral
Primarch: Jeckel Luppolt
Nickname: The Fitzemperor
Modifier: -1 (Early Life)

Early Life
Jecket fall on Caral, a Feral World were humanity is always under the danger of beasts and monsters, and believe that the strong and superior rule the weak.

He was perceived as a superior being by the population, almost like a divine being. Slowly but surely, people begin to assemble around him, and soon a whole population live under the Primarch.
Jeckel unify humanity under his banner, than lead the massacre of every beast and monster on the planet. He then lead humanity into a new age of technology, helping the population reach space and colonize the Caral System, building himself his how dominion to rule.

When the Emperor finally showed up, Jeckel was clearly not happy to learn that is superiority isn't unique, and that there is an even superior being to him. Refusing to abandon his personal empire to go on the Great Crusade, he launched his ships on the Imperial Fleet, but was defeated, after what he grudgingly accepted to join his father.

He was presented with his Legion, the Storm Knights. Amazed by the superiority of this army over his troops on Caral, he gladly took control over the Astartes

The process

• He was perceived to be a superior being, a messiah, or maybe even a god. (-1)
• Feral World: A world where humanity is threaten by powerful beasts and monsters, so much that people leave under the principles that the strong rule the weak. (-1)
• Yes, and with the general support of the population (+1)
• The Primarch developed technology so far ahead than what it has been than he is able to colonize the entire system, ruling over a stellar empire. (+2)
• Yes (-1 since Jeckel is perceived to be a superior being)
• No (refused to join the Emperor) (-2)
• Kept it like it was, knowing they would eventually adapt to their Primarch themselves. (+1)
• 0-1-1+1+2-1-2+1= -1 modifier

EXEMPLE #2


Legion: White Swords (previously Ultra Wings)
Number: XI
Homeworld: Atahan
Primarch: Severus Polemarch
Nickname: The Alabaster Sun
Modifier: +5 (Early Life)

Early Life
Severus felt on Atahan, a Hive World ruled by an oligarchy who viewed people as resources. He was raised by a member of the oligarchy. He was raised under materialist and economic ideologies, but rapidly realised the inequalities of his world.

He ended up using the dissatisfaction among the slaves, lovestocks and the rest of the population against the oligarchy and took power with popular support, thus betraying his adoptive father. Instead of leading the new government himself, Severus delegated the powers to good and competent mens that he had faith in, and took little to no part in the politics of Atahan.

When the Emperor arrived and ask his son to join him, Severus gladly complied, knowing that his world didn't need him and could manage itself.

He was then presented to his Legion, the Ultra Wings. He changed their name for the Wite Swords, after the colour his own sword (which he called “the most valuable weapon on Alahan”) and delegated many responsability that would normaly fall on the Primarch to the Lord Commanders of the Great Companies.

The process

• He was adopted as the son of an important person and part of the upper class. (+2)
• Hive World: Large Hives controlled by a materialist and economic oligarchy who sees people as nothing more than resources. (-2 since Severus is the son of an important man)
• Yes, and with the general support of the population (+1)
• Instead of taking an active part into politic, he delegated responsibilities to competent individuals and only participate when needed to. (+1)
• Yes (+1)
• Yes (+2)
• Renamed his legion and change it to mark a new beginning for it.
• 0+2-2+1+1+1+2= +5 modifier

OK, this part is probably the longest and most complicated part of this Generator.

There was many ways of doing some sections of it, so I decided to go with the simplest ways of doing things and to put the other ways into a section named Alternate rules. I'll make one of my examples with alternate rules and the other without them, so you can see the difference and chose what you prefer.

There also two new things that should be taken in account:

The first one is the list of friends and enemies between your Primarch and his brothers. Many Primarchs have friends and enemies among themselves. For example: Fulgrim and Ferrus Manus are friends, while Rogan Dorne and Pertruabo are enemies. Your Primarch start with one friend and one enemy, but the list can grow as the Great Crusade goes on.

The second one is the introduction of the Countdowns, the first one being the Ulanor Countdown. Each campaign that your Primarch and his Legion do will lower the countdown, and when it come to 0 the Crusade of Ulanor happen.

So now, your notes should look something like this:

Legion: Legion Name
Number: Legion Number
Homeworld: Homeworld Name
Primarch: Primarch Name
Nickname: the Nickname
Modifier: +/- something (Early Life)/ +/- something (Great Crusade)

Ulanor Countdown: 20 (If your countdown stop on 0, your Primarch is present for both the Crusade and the Triumph of Ulanor. If it stop on -1 or -2, your Primarch is only present for the Triumph of Ulanor)

Friends:

Enemies:

Campaigns

__
The Primarch with who your Primarch really getting along. (1d20)
Take the Primarch whose Legion's number you roll (re-roll if 2 or 11). Here is the modifier you get when you become friend with someone.

• -5 if it's Horus
• -2 if it's Lorgar
• -1 if it's a Primarch who'll turn traitor.
• +1 if it's a Primarch who'll remain loyal.
• +2 if it's Sanguinious

• +1 if it's a Primarch who'll turn traitor.

___
CAMPAIGNS
Here is te complicated part I talked about. This is made to simulate the most memorable campaigns of your Primarch along his brothers. Normally, you'll get fron 5 to 8 campaigns, depending how well it went for your Primarch. One campaign is roll in the following order:

• Fellow Primarch Present
• Who is the enemy?
• Difficulty of the Campaign
• Complications

When it is done, you just do it again until your Ulanor Countdown has reach 0 or less.

Fellow Primarch present (1d20)
This is to decide which other Primarch is there during this campaign. Take the Primarch whose Legion's number you roll. On a 2 or 11, your Primarch is alone on this campaign. Note that modifiers are added to The Modifier depending who is along you during a campaign.

• -2 if it's Lorgar
• -1 if it's a friend who later become a traitor
• -1 if it's an enemy who remain loyal
• +1 if it's a friend who remain loyal
• +1 if it's an enemy who later become a traitor

Who is the enemy? (1d10)

• 1-5: Humans
• 6: Eldars
• 7-8: Orks
• 9-10: Another kind of Xenos

Difficulty of the Campaign (1d10)
This will determine how well your Legion did on the campaign. The number in the () is by ow much you lower the countdown. If it has ether à + or a -, it is for The Modifier, not for the Countdown.

• 1-2: Swift Victory, quick and total, one of your best and easiest campaigns. (1)
• 3-4: Easy Victory, took some time but was overall simple. (2)
• 5-6: Well Deserved Victory, many efforts were put into this campaign, and they paid off in the end. (3)
• 7-8: Hard-Won Victory, this campaign was long and difficult, ether because of the enemy being stronger than planed or there was some errors made during the war. (4)
• 9-10: Bitter Victory, it took an eternity to finish it, too much troops died on it, and massive mistakes were made that prolonged the campaign. Your Legion prefer to not talk about this campaign. (5)

Complications (1d10)

• 1: Your Primarch made a mistake so enormous that the Emperor himself had to come clean the mess. The humiliation for your Primarch was enormous. (-2, lower the Ulanor Countdown by 2)
• 2: A dispute over tactics between the Primarchs present on this campaign cause an error that significantly slow the war, and each Primarch accuse the other of being responsible. (lower the Ulanor Countdown by 1, add the other Primarch on this campaign as an enemy, unless he is your Primarch's friend, in which cause they find some compromise and stay friend.)
• 3: Some unknown enemy secret weapon cause problems in the offensive and make the victory more difficult to achieve. (lower the Ulanor Countdown by 1)
• 4: One of the Primarchs on this campaign (yours or the other one) act in an excessive way, leaving bitter memeries of this campaign. (-1)
• 5-7: The campaign goes with no serious complication.
• 8: Due to some events in this campaign, the Imperial Army comes to respect your Primarch and his Legion, while they themselves begin to appreciate the Imperial Army. (+1)
• 9: This Campaign allow your Primarch to get close with one of his brother, both realizing they had more in common than they thought. This new-found cooperation and friendship allow for a faster campaign. (the Ulanor Countdown goes up by 1, add the other Primarch on this campaign as a friend, unless he is already your enemy, in which case it was more of a temporary cooperation your Primarch quickly refuse to continue. )
• 10: The Emperor himself is part of this campaign, your Primarch have the honour of fighting alongside his father. (+2, the Ulanor Countdown goes up by 1)

Ulanor Crusade (1d6)
If your Countdown stopped on 0, your Primarch and his Legion are present on Ulanor.

• 1: Against all odds, the Emperor order your Primarch and his Legion to stay out of the fight, and refuse to let them participate, despite the protests of your Primarch. (-5)
• 2: An error in a timing, a charge too soon or your Legion broke formation for some reason. Whatever was the mistake made, it cost a lot to the Imperial forces, and Roboute Guillimane hold your Primarch personally responsible for that mistake and will never stop reminding you of it. (-3)
• 3: The number of Orks killed by your Primarch is astonishing, some Imperial historians mentioning “A mountain of corpses blocking the sky”.
• 4: Ulanor allowed your Primarch to grow closer with Jagathai Khan, one of his fellow brothers. (add Jaghatai Khan as friend, or if he is an enemy remove him from the enemies, +1)
• 5: The actions of your Primarch and his Legion saved tens, if not hundreds of thousands of troops from the Imperial Army. The Army will celebrate your Primarch's actions for centuries. It is a good day to be part of the Imperium. (+3)
• 6: For the last time, your Primarch was able to fight alongside the Emperors. The sight of father and son, back-to-back and making their way through waves of Orks, will remain in the imperial history forever. (+5)

Ulanor Triomph (1d6)
In front of is brothers, Horus is made Warmaster, and the Emperor retreat himself from the Great Crusade. What do your Primarch think of Emperor's choice of naming Horus? (If Horus is your Primarch's friend, he automatically support the nomination. If he is his enemy, then he cannot support it)

• 1: Your Primarch think he should have been named Warmaster, and that the Emperor made a mistake. (-3)
• 2-3: Your Primarch would have preferred another Primarch tan Horus. (-1)
• 4-6: Your Primarch agree with the Emperor that Horus is the best choice. (+2)

Here is the table for your Primarch reaction if he wasn't present at the Triumph:

• 1: Your Primarch think he should have been named Warmaster, and that the Emperor made a mistake. (-1)
• 2-3: Your Primarch would have preferred another Primarch tan Horus.
• 4-6: Your Primarch agree with the Emperor that Horus is the best choice. (+1)

Alternate rules
Those are custom rules is sometime used. You can use them however you want.
When you roll the difficulty of the campaign, instead of rolling it once, roll it once for each Legion present, and then calculate the average. This is mainly to show that one Legion did better while the other held the campaign down, which can make interesting fluff.
Once, you can roll 2 Legions instead of 1, making it a bigger and more important campaign.


EXEMPLE #1

Legion: Storm Knights
Number: II
Homeworld: Caral
Primarch: Jeckel Luppolt
Nickname: The Fitzemperor
Modifier: -1 (Early Life)/-4 (Great Crusade)

Great Crusade

Friends:

• Horus. Somehow Jeckel came to respect Horus and his skills, and they became close friends.

Enemies:

• Ferrus Manus. Jeckel always looked down on Ferrus Manus because he believe the Iron Hands Primarch to be weak due to his metal hands, while Ferrus Manus just never supported Jeckel arrogance.
• Jagathai Khan. After the Khan refused to listen to Jeckel on the Roglert Campaign, Jeckel was forced to go save his brother, which also caused a stop to the campaign. This little adventure convince Jeckel that Jaghatai Khan is an imbecile.

Ulanor Countdown: -1 (20-4=16/ 16-3+1=14/ 14-5=9/ 9-2=7/ 7-4=3/ 3-4=-1)

Campaigns

• Motogon Prime Campaign: Along the Thousand Sons, the Storm Knights fought human and obtained a difficult victory, mainly due to the Storm Knights themselves, who kept making mistakes after mistakes. They prefer to forget that without Magnus's help, the Fitzemperor and his legion would have been stuck in this campaign for an eternity. (4)
• Stercent IX Campaign: Once again along Magnus and his legion, they faced a human society full of psykers. Those psykers where actually quite a problem for the Thousand Sons, but the arrival of the Emperor allowed a the Legions to obtain victory and memories they will never forget. (3, countdown up by 1)
• Roglert Campaign: With the White Scars. This campaign ended up in a bitter victory, mainly due to the waste of time the Storm Knights took saving the White Scars, who were stuck in the middle of orks territories. Jeckel openly called Jaghatai an imbecile and a barbarian following the campaign, thus making another foe among his brothers. (5)
• Sidoris Cluster Campaign: Once again with the White Scars, the Sidoris Cluster held a human empire that refused to join the Imperium. It was an easy campaign, in which the White Scars proved their skills and talents through swift and efficient conquests, to the anger of Jeckel. (2)
• Ravar Campaign: Along Leman Russ and the Space Wolves, they went liberate a human world under Orks assault. The locals decided to join the Imperium in the fight when they say te two Primarchs arrived. Jeckel made numerous mistakes during this campaign, and the Space Wolves were forced to clean behind the Storm Knights failures. (4)
• Calisma II Campaign: Fighting a planet full of insect like Xenos, the Storm Knights face better resistance than planned, forcing them to spend too much time on this campaign to join the Emperor on Ulanor. (4)

Ulanor Triumph
Jeckel, the so-called "Fitzemperor", arrived on Ulanor alongside other legions, coming fresh from the Calisma II Campaign. When his longtime friend Horus became Warmaster, he was among the first to congratulate him.

Stercent XI Campaign example:

• Rolled 15 for the Legion. The XV Legion is the Thousand Sons.
• The enemy is human
• Well Deserved Victory, many efforts were put into this campaign, and they paid off in the end. (3)
• The Emperor himself is part of this campaign, your Primarch have the honour of fighting alongside his father. (+2, the Ulanor Countdown goes up by 1)
• The Campaign downed the countdown by 3, but the Emperor helping got it up by 1, so the countdown goes down by 2
• Also give +2 modifier

EXEMPLE #2

Legion: White Swords (previously Ultra Wings)
Number: XI
Homeworld: Atahan
Primarch: Severus Polemarch
Nickname: The Alabaster Sun
Modifier: +5 (Early Life)/ +6 (Great Crusade)

Great Crusade

Friends:

• Rogal Dorne. He was the one who showed him ow the Imperium work and how to lead his Legion. Since then, Severus had the utmost respect for his mentor.

Enemies:

• Lorgar. Severus, raised in a materialistic society who only believed into resources and money, never got along with the religious Lorgar.
• Lion El'Jonson. After Severus mistake let the Eldars escape Cariel Secundus, Lion El'Jonson and Severus began to exibit a complet lack of respect for each other.
• Mortarion. The tactics and gas weapons of Mortarions were criticized by Severus, which started a mutual hatred between the two.

Campaigns

• Kangossa III Campaign: With Ultramarines against a strange race of bear-like Xenos. Due to the unconventional tactics of the Xenos, the Ultramarines had some difficulties, and so the White Swords stepped in to save the day. (4)
• Hiapha Cluster Campaign: A deserved victory along the Raven Guards on a group of Dark Eldars. Even with many losses, the White Swords came out of this victory, especially thanks to Corax tactics. (3)
• Liahide Campaign: With the Death Guard. This victory ended up baddly due to the gas used by Mortarion, which killed a great part of the human population, much to Severus shock. It left a bad taste in the Primarch mouth. (2)
• Cariel Secundus Campaign: With the Dark Angels. They led an assault against Eldars, but they were able to escape due to a problem in the Astartes formation. Lion accused Severus, and hatred between the two Primarchs grew since. (1, countdown down by 1)
• Areraxis Campaign: The surprise attack of Severus on Areraxis was a total surprise for the population. Following the first battle, the Alabaster Sun was joined by his father, who was able to convince the citizens of the planet to join the Imperium and surrender. (1, countdown up by 1)
• Septepian V Campaign: Alongside Konrad Curze and Magnus the Red. This human world was a hard fought campaign for the White Swords and Night Lords, but the arrival of the Thousand Sons allowed a total victory. (3)

• Kryodus Campaign: In the quick campaign against the Orks, the tensions between Mortarion and Severus finally blew up, and their constant disagreement cause many problems during the campaign. (1, countdown down by 1)
• Palius Campaign: In what seems to be a difficult campaign against Xenos, the arrival of Fulgrim and his Legion turned the tied of the war, and greatly helped Severus. (2)
• Ulanor Crusade: The Wite Swords and their Primarch saved many of the imperials based established on Ulanor during the war, saving hundreds of thousands troops whose lost could have been a problem to the campaign. Severus was acclaimed as a hero by the Imperial Army, and from this day a bond between the White Swords and the Imperial Army was born.

Ulanor Triumph
Severus was among the Primarchs present for the celebration of the Ulanor Crusade, in which he played a role himself. The Guards charged to protect the palace in which the Emperor resided on Ulanor were chosen by Severus himself and were among the ones he saved. When Horus was made Warmaster, The Alabaster Sun (his nickname) was surprised like everyone, although he supported the choice of his father, knowing that the Emperor would never make a wrong choice.

Loyalist losses (Loyalist) (1d8)

• 1-2: Your Legion is pretty much destroyed, maybe a dozen of Astartes or so survived the fight. Your Legion is unable to participate in the Heresy, being to weak to do anything and prefering to focus on rebuilding its forces (Terra Countdown: -2)
• 3-5: Your Legion is mostly destroyed, and will not be able to participate until the latest part of the Heresy. Due to the necessity of returning to its Homeworld, your Legion will need to pass through (Terra Countdown: 2, can't fight in Terra without a Victory in a battle)
• 6-7: Your Legion made it out of Itssvan V with a somewhat weak but workable number of troops. After escaping the horrors of the Drop Site, they must make a choice: waging war on the Traitors (Terra Countdown: 5) or directly go re-enforce Terra with what the troops left (Terra Countdown: 0)
• 8: Your Legion somehow got out of the Drop Site Massacre with relatively few losses, which is an incredible feat by itself, and shall be told by future Astarates for generations. However, "relatively few" in the Drop Site Massacre still mean that easily a third of your men were killed, but unlike the other loyalists that were presents, your Primarch can wage war against the traitors . (Terra Countdown: 10)

EXEMPLE #1

Legion: Storm Knights
Number: II
Homeworld: Caral
Primarch: Jeckel Luppolt
Nickname: The Fitzemperor
Modifier: -1 (Early Life)/-4 (Great Crusade)/-2 (Warmaster Crusade)
Side: Traitors (Chaos Undivided)

Friend:

• Horus. Somehow Jeckel came to respect Horus and his skills, and they became close friends.

Ennemi:

• Ferrus Manus. Jeckel always looked down on Ferrus Manus because he believe the Iron Hands Primarch to be weak due to his metal hands, while Ferrus Manus just never supported Jeckel arrogance.
• Jagathai Khan. After the Khan refused to listen to Jeckel on the Roglert Campaign, Jeckel was forced to go save his brother, which also caused a stop to the campaign. This little adventure convince Jeckel that Jaghatai Khan is an imbecile.

Itssvan V countdown: -3 (10-1=9/ 9-3-1=5/ 5-2=3/ 3-6=-3)

Campaigns:

• Ravak II Campaign: Ravak II was quickly braught into the light of the Imperium by the Storm Knigts during one of their fastest campaign. However, following the victory, the locals rebelled against the newly imperial administration. Furious, Jeckel ordered the brutal massacrer of the Great Cities of Ravak II, killing a quarter of the population in the process. (1)
• Milas Cluster Campaign: A campaign to reconquer a human world, the locals seems to have a high number of Psykers and to be using some kind of "beats" unkown to the Imperium, leading to a highly difficult and troubling campaign ofr the Storm Knights. Since the end of the campaign, Jeckel try his best to forget about those things. (3, lower Itssvan V Countdown by 1)
• Almar Campaign: Like on Ravak II, the local population rebelled after what was tis time a longer campaign (altought as easy) for the Storm Knights. Jeckel, unable to support defiance against is autority, launched his Legion against the population. (2)
• Talbir Campaign: The first (and only) campaign of the Storm Knights against Xenos, the war quickly turned into a living hell for Jeckel and his Legion. The Xenos happened to own advanced tech and giant war-beasts that could challenge even Titans. The lack of preparation for what was believed to be an easy campaign is also to blame. (5, lower Itssvan V Countdown by one)

Side: Traitor. Jeckel never forgive the Emperor for taking his place as the "Superior Being" and for taking away his own little realm. Added to this is the clear lack of respect he received from the "liberated world" which lead to his violence against conquered populations in the late Crusade. Finally, his meeting with the Ruinous Powers during the Milas Cluster Campaign made him discover a new tool to gain power, even if he only wished to forget about it at first. So when Horus, the only Primarch for who Jeckel had respect and admiration, came asking for his forces, he gladly accepted.

• Rolled 16. 16-1-4-2=9. 1-10=traitor. Jeckel join the traitors

Gods: Chaos Undivided

Milas Cluster Campaign example:
The enemies are humans
Well Deserved Victory, many efforts were put into this campaign, and they paid off in the end. (3)
Some strange phenomenons affect your ennemies. They seemed odds, corrupted by something. (lower the Itssvan V countdown by 1, roll the “Mark of Chaos” table)
Your Primarch, although shocked, try not to think too much about what happened

EXEMPLE #2

Legion: White Swords (previously Ultra Wings)
Number: XI
Homeworld: Atahan
Primarch: Severus Polemarch
Nickname: The Alabaster Sun
Modifier: +5 (Early Life)/ +6 (Great Crusade)/+1 (warmaster Crusade)
Side: Loyalist

Itssvan V countdown: -1 (10-3=7/ 7-5=2/2-2-1=-1)

Campaigns:

• Faral Prime Crusade: Faral Prime was a world where Xenos diminated a majority of humans, who "willingly" worked for them. Severus launched an assault against them, believing it would be an easy campaign. However, the victory was hard fought for the White Swords. (3)
• Aradius V Campaign: One of the most difficult campaigns of the White Knights during the great crusade, the logistic problems during the conquest of this human world turned an already difficult campaign into a living hell. A a good note, the White Swords and their Primarch were once again able to develop good relations with the Imperial Guard, many survivors of Ulanor being present on Aradius V. (5)
• Farages Campaign: What began as a simple campagn against humans turned into a war of attrition following the discovery of massive super weapons on Farages. Unwilling to risk the life of his troops (Astartes and Guards), he decided to play the long game. Due to this, he was unable to answer the call for Itssvan V. (2, lower Itssvan V Countdown by 1)

Side: Loyalist. Severus never liked faith, always believing it to cloud the judgement of humanity. Since Ulanor, the White Swords built close ties to the Imperial Organizations, especially the Guards, which containded many friends of the Primarch. Most than anything, Severus wanted to see this world free of gods and tyrants that the Emperor was trying to build, a world where Severus believed Humanity would not need him to guide them toward their destiny.

• Rolled a 4. 4+5+6+1=16. 11-20 is loyalist, and so Severus stay loyal to the Imperium.

SIEGE OF TERRA
The final battle of the Heresy.

Event (1d10) (Loyalist)

• 1: As hordes and hordes of demons and traitors swarm toward his position, your Primarch still wouldn't move. But even a Primarch has its limits, and the stories say that he died on his feets, holding ground, and that even as only his corpsed remained he refused to move, still up on is two feets.
• 2: In the anarchy that was the Siege, your Primarch found himself face to face with one of his traitor brothers. The figth, although mythic, was won by the traitor, who took a personal pleasure in destroying your Primarch body.
• 3: A massive Greater Demon met your Primarch. This epic fight could have been won, but the intervention of ether other demons or traitor Astartes left the chance for the Demon to strike, which he did.
• 4: The Emperor went on the Vengeful Spirit followed by Rogal Dorne, Sanguinius and your Primarch. However, when your Primarch got separated from the others, he found his way to Horus before the Emperor. And when the Emperor finaly arrived, he found the corpses of two sons at the feat of Horus...

When everyone got separated, your Primarch had to go through an army of Sons of Horus, facing some of Horus lieutenants in the process.

• 9: As he was making is way through traitors, your Primarch got face to face with one of his traitorous brothers. An epic and legendary duel followed, but none of them was able to win the fight. This doesn't stop the Legions of both Primarchs to brag about their Progenitor's victory, however.
• 10: At the peak of the Siege, a Greater Demon appeared. Knowing what he had to do, your Primarch went on and killed the Demon in a spectacular showdown. This gave a boost of moral to every Imperial troops present.

Event (1d6) (Traitor)

• 1: Your Primarch was somehow able to make it to the Adaptus Costodes, and in an attempt to face the Emperor himself, tried to kill them all. Although he killed a great number of them, the elite guard of the Emperor and the reenforcement that came to put your Primarch down were finally able to kill him.

• 5: As the rampage of your Primarch went on, a loyalist Primarch tried to stop him. However, none of them ever gained the ascendent over the other in this clash of giants. The fact that your Primarch may have win is a definite proof that he is a danger for the Imperium.

Primarch: Jeckel Luppolt
Nickname: The Fitzemperor
Side: Traitors (Chaos Undivided)

Terra Countdown: 1 (15-5=10/ 10-3=7/ 7-6=1)

Battles:

• Battle of Corvos III: Along with the Word Bearers, Jeckel and his Legion faced Leman Russ and his Space Wolves. The battle was long and hard fought, but with the Powers of Lorgar, the battle was a victory, forcing Leman Russ to retreat. (5)
• Battle of Luna Caltar: A spaceship battle was engaged between Perturabo and Jeckel against Roboute Guilliman and Sanguinius. It was a victory for the traitors, but not a major one like Jeckel wanted. (3)
• Ambush of the Farian System: While travelling through the Farian System, Jeckel was ambushed by a combined force of White Scars and Blood Angels. I was a slaughter for the Storm Knights, and easily one of the worst defeats of the Traitors during the entire Heresy. (6)
• Siege of Terra: Since the beginning of the Heresy, Jeckel passed from knowing the existence of chaos to being a powerful sorcerer of the Ruinous Powers. When he arrived on Terra, he lead an army of demonic beasts, with the Storm Knights at their head. The "Host of the Fitzemperor", like many would call it, wrecked havoc on Terra until the news of Horus death came to Jeckel, after which he quickly abandoned the planet.

• Battle of Radenus Prime: On Radenus Prime, Severus and his Legion were pinned down by Lorgar and Fulgrim. Should a dispute had not started between the two traitor Legions, the White Knights may have not make it out of there alive. Severus was even hurt baddly during the fight.(6)
• Ambush of Pluto: Even wounded, Severus still decided that he needed to stop Horus before he got to Terra. With what was left of his fleet, he ambushed Horus, who was quickly joined by Lorgar and Alpharius's Legions. But this last attempt to stop the Warmaster byt the Alabaster Sun was an utter failure, and he was defeated and chased out of the Sol System, making him unable to act during the Siege of Terra. The last battle of the Heresy for the White Swords was a total defeat, especially since the wound of Severus only got worst, as he ended up cutting down his left arm, which had became a liability for him since Radenus Prime. (4)

PART 5: AFTERMATHS

Easily the shortest part of this long generator, it mainly give guidelines about what happened to the Primarch following the Heresy.

What happened to the Primarch? (1d6) (Loyalist)

• 1: Killed by a traitor Primarch during the counter attack that followed the Siege of Terra.
• 2-3: Disappeared shortly after the Codex Astartes was created by Roboute Guillimane.
• 4: Was killed in later campaigns for the Imperium.
• 5-6: Stayed long enough to realize he was one of the last Primarchs still around, and finally disappeared shortly for mysterious reasons known only by its chapter.

What did they think of the Codex Astartes? (1d8) (Loyalist)
If Roboute Guillimane is friend with your Primarch, you ether accept it or follow it to the letter.

• 1-2: Your Primarch massively opposed it along Leman Russ and Rogal Dorne. However, later events would force him to comply to it.
• 3-4: Your Primarch accept grudgingly to accept it, but many rules of the Codex aren't respected by the newly formed Chapters.
• 5-6: Your Primarch accept to follow the Codex, admitting the necessity of such reforms.
• 7-8: Your Primarch believe that the Codex the future of the Astartes, and force is Chapters to follow it to the letter

How Many Successor Chapters from the Second Founding? (1d6) (Loyalist)
If your forces were decimated on Itssvan (Terra Countdown: -2), your Legion is too weak to divide into Chapters. If they were on Itssvan V, roll 1d4 instead of 1d6.

• 1: 0
• 2: 1
• 3: 2
• 4: 3
• 5: 4
• 6: 5

What happened to the Primarch? (1d8)(Traitor)

• 2-5: Similar to the other Traitor Legions.
• 6: It has become a real problem, like in the Black Legion.

EXEMPLE #1

Legion: Storm Knights
Number: II
Homeworld: Caral
Primarch: Jeckel Luppolt
Nickname: The Fitzemperor
Side: Traitors (Chaos Undivided)

Aftermaths
Following death of Horus, Jeckel was forced to retreat in the Eye of Terror along the other Traitors. There, he established his personal domain, with the planet of Carven as its capital. It is said he built himself a throne on the planet, and waited patiently the gift of Daemon Princedom from the Gods.

However, when it became clear that it would never come, the Storm Knights abandoned their Progenitor, seeing as pathetic compared to the other Primarchs, who had already became Princes by then. They chattered into warbands and left Carven. Without his Legion, Jeckel little empire crumble, his army of demons failing to keep his control in all this chaos.

Jeckel, abandoned by his men and failing to keep the realm he always thought he deserved, abandoned Carven and disappear, searching for a way to prove the Ruinous Powers that he deserved to be a Prince Demon like his brothers.

The Storm Knights, who became know for their use of demons in their armies, still fear his eventual success as of the 41th Millennium, as they believe his ascension and return would be follow by his vengeance against the Legion that abandoned him and cost him his empire. Nobody really know were Second Primarch is, although sighting of "The Host of the Fitzemperor" are mentioned during Black Crusades. Whenever it is true or not is anyone guess...


EXEMPLE #2

Legion: White Swords (previously Ultra Wings)
Number: XI
Homeworld: Atahan
Primarch: Severus Polemarch
Nickname: The Alabaster Sun
Side: Loyalist

Aftermaths
Following the end of the Heresy, Severus helped Roboute Guillimane in his reforms of the Imperium, especially in the Imperial Army, where Severus gained many friends over the years. However, he eventually delegatd his power to others, like he usually do, and in the end had little impact on the restructuration of the Imperium.

When Roboute Guillimane created the Codex Astartes, Severus admited the necessity of such reforms. Due to his habit of leaving the important decisions in the hands of is lieutenants, who each lead their troops in their own way, the transition into chapters was made easily. Three new Chapter were born from this division:

• the White Eagles
• the Alabaster Guard
• the Honoured Jaguars

Following the division, Severus said that in the Chapters "didn't need their Primarch around" and went away on a "Personal Quest", leaving only behind his personal blade to the new Chapter Master of the White Swords, an artifact still own used as the main weapon of the Chapter Master. Following his disappearance, many speculated that he would one day return, although the White Swords and their Successors don't believe he will lead them once he return.

Many of the soldiers that fought alongside Severus and his Legion named their sons after him, and today Severus is a common name in the Imperium. Just like their Primarch, the White Swords kept close ties with the Imperial Guard, and it is frequent to see them and their Successors causally interaction with members of the Guard. And even today, many believe that the Alabaster Sun will rise once again upon the Imperium.
___
And this my generator. Yeah, I agree its long, but I always found it fun.

I think this is great however my gripe with this is the points that effects your choices like in the Great Crusade. This GC,WMC and the Horus Hersey really confused me with the points. Perhaps you could explain it easier or simplify it? Also I think you should add more options in there like the Legion continues to fight on in the Hersey even if the Primarch is killed in the first battle

This what I got which is not nice lol


Legion: Glaucous Templars
Number: II
Homeworld: Mousillon
Primarch: Janusch Feuer
Nickname: The Silver Ritter
Side: Loyalist

Janusch Feuer, Primarch of the Silver Cavaliers later renamed the Glaucous Templars was born on Mousillon where he was found in a crater by Holy Mousillon Knights whom would later adopt him as one of his own believing him to be a Star Child. As a child, he quickly grew and became skilled in warfare, becoming a Crusading Knight called a Templar and fought in a dozen campaigns secure the land with his adoptive parents. In the 27th Crusade, He took command of his parent's knightly Order during battle when his adoptive parents were slain in battle by hordes of ebony infidels where he led them in a near perfect victory, crushing the enemy in battle and seized the ebony city itself and soon controlled it. With his new powers as a Lord Templar, He began his own crusade to conquer all of Mousillon in the names of the knights who had adopted him. Within a ten year war, he conquered Mousillon and began planning with his Lord Commanders to conquer the solar system when a mysterious golden figure. This golden figure was quickly labeled the Star God of Mousillon with all bowing before him. When he reached the Ebony Palace, now purified with a silver-bluish like color, when Janusch Feuer saw the Star God, without hesitation he bowed before the Star God. The Emperor knew Janusch Feuer was his son and asked him to join him in the Great Crusade at his side, Janusch Feuer hastily accepted having the same idea. Before all the lords of Mousillon, Janusch Feuer swore fealty to the Emperor and proclaimed to his father, all Lords and his adoptive sister present the Grand Crusade shall begin sooner than expected vowed he would stop until the Galaxy was conquered.

Days later he and his sister met the II Legion, the Silver Cavaliers whom doctrine was shock and awe, to crush the enemy at the greatest moment with two-handed weaponry. He decided rename his Legion Glaucous Templars as the beginning of a mark on their history. He had named the Glaucous Templars due to the Ebony City being purified of Chaos Taint and changing colors from black to Glaucous Silver. He would continue his hunt against Chaos, even in secretly if possible. After taking control of the Glaucous Templars, He organized the Legion, it's traditions and ideologies to reflect Mousillon and her Templar Knights. Many Templar Knights from Mousillon joined the II legion with his sister, Marianne Feuer joined the II legion as well as a Pseudo Astartes with her taking her place alongside her brother as his advisor and even a Lord Templar Commander when needed.

During the Great Crusade Janusch Feuer became close with his brother Rogal Dorne who often fought in the same campaigns with the Glaucous Templars often going on the offensive while the Imperial First secured Defense lines and fortified locations of importance, not to mention the importance of the Crusade and their father. However, it was during this time Rogal Dorne introduced him to Huros who immediately gave Janusch Feuer red flags, He wasn't sure why but something about Horus seemed off or something was wrong with him This led to him being isolated from his brothers although the majority of his brothers often didn't take liking to him in the first place for some reason. Following this, following this on the direct orders of the Emperor, Janusch Feuer returned to Terra where the Emperor told his son in complete secrecy
that he, the majority of his people of Mousillon, his sister and his Legion were psychic Pariahs along with Their true objective in the Great Crusade was to ride the galaxy of Chaos and that they were the only to do it since they could not fall to the temptations of Chaos. Due to this, the Emperor orderd his son to work in complete secrecy and to never tell of Chaos to anyone, even his brothers. Janusch Feuer accepted this burden and with the orders of the Emperor himself, the Glaucous Templars began their crusade on Chaos in secret often working in complete secrecy or misleading others when allied during a campaign or battle which caused even bigger rift between him and his brothers, only strengthing his bond with Marianne even more. During this time, despite Marianne being a Pseudo Astartes, she often fought alongside her brother as one, able to read each other movements and often thoughts where they became a nearly unstoppable force when working together but this was not common. Marianne had formed her own Valkyrie unit, the Sisters of Silence whom she often led in battle when not with her brother.

After the Ullanor Crusade, after fighting by his legions and his father's side and showing the true martial abilities of the Templars, showing such ferocity and determination not since seen impressed the Emperor himself but not enough when the Emperor declared Horus "Warmaster" which. Janusch Feuer was absolutely saddened and livid that he or once or one of his more strategic brothers wasn't chosen, He always knew Horus was the favorite but it never bothered him since the Emperor never openly showed it until now. Upon seeing this, Janusch Feuer openly challenged Horus to an Honour duel which before Horus could answer, The Emperor openly told him as he stood before him. If he was to question the Emperor's wisdom, he would need to battle him instead. Knowing he was beaten before the battle could even be joined, With his sword, Janusch Feuer bowed before the Emperor, taking an Oath to openly follow Horus's Command and out of duty even though in mind, he was embittered by it. Even though the Emperor and Horus accepted this Vow, this oath, this had permanently damaged Janusch Feuer's relationship with the two and would never recover as the Emperor grew more and more distant from his son and with Horus giving him less "Glorious" campaigns for his legions even though the Glaucous Templars had a habit of disobeying orders and following their own Crusade with the Imperial Army behind them in their eternal crusade on Chaos.


During the closing days of the Great Crusade, Janusch Feuer with his legion fought alongside Lorgar with the Word Bears during a military campaign where the Human populace of this fallen, crumbling empire was tainted and followed the Rune powers of Chaos. Despite the technological and military superiority of the Imperium, The war ended eventually with a hard-won victory but only after many years of constantly long and difficult battles, these Humans were dug in everywhere and were fanatical, dying by the millions willingly for their gods who they thought would save them. Not to mention Lorgar would often mysteriously withdraw his Legion from the battlefield often at times to gather and study the Religious structures, tomes and even capturing of their prophets. Lorgar gathered all of this and studied them, becoming fascinated with them which would slowly change him. Janusch Feuer saw this through his talks with him, his stances with him and even looking at his eyes. Janusch Feuer knew he had changed but he knew couldn't directly challenge Lorgar, no instead he would have to do what is right. Following this bloody crusade, His sister Marianne took command of the Glaucous Templars and continued their crusade on Chaos while Janusch Feuer returned to Terra itself to tell the Emperor that Lorgar had most likely fallen to Chaos, finding the Gods he so wanted to worship since he could not worship their father. Upon hearing, The Emperor did not believe Janusch Feuer and entered a fiery debate with his father for hours until Janusch Feuer stormed out of the Imperial Palace which had basically had ended his relationship with his father, this would be the last time Janusch Feuer or the Emperor would see each other again. Despite this falling out though, he would continue his duty to the Imperium and his duty with the Destruction of Chaos.

When the beginning of the end began with Horus rebelling against their father, Janusch Feuer was not surprised at all by this result, knowing something like this would happen but could never state it to their father since he could believe one of his sons could fall, as a result he was blinded and nothing could be done. When Horus took his brother's and their Legions as well, it was time to end this at Ittssvain before it could begin. When the Itssvain Massacre began with the so-called Loyalist Legions turned traitor and began ripping apart the line, The Glaucous Templars were spread out along the Loyalist Line, providing any support while Janusch Feuer in the middle where the fighting was thickest, leading constant assaults on the traitor line to keep them at bay while his sister, Marianne led the defensive forces. Eventually even the primarch was pushed and when it became apparent there was no hope for victory and they needed to withdraw if they were to have any hopes of surviving the battle. Janusch Feuer and the part of his Legion that was with him decided to stay behind on Itssvain to give Corex, Vulken and what remained of the legions enough time to withdraw. By this time most of his Legion was destroyed and while most were determined to die with their Primarch, Janusch Feuer for the last time hugged his sister, Marianne and ordered her to take what was left of their Legion and withdraw with Corex while he stayed behind. Although she hesitated for a moment, she did not dare question his orders and silently accepted his orders. With their withdraw, Janusch Feuer and his sons continued their last stand against the traitors. When it became apparent it was taking longer than expected to eliminate Janusch Feuer and what remained of his legion, Horus ordered both, Perturabo and Angron to kill Janusch Feuer fully knowing Janusch Feuer martial abilities enough to know he was too much for a single opponent to take on directly. Janusch Feuer fought heroically against his two brothers but even he could not stand against two of his brothers forever. When he knew the loyalist had escaped, he lowered his duel great swords and allowed himself to be killed knowing he had completed his duty.

With the death of their primarch, The Glaucous Templars forever knew shame and regret, not being able to die alongside their Primarch and knowing they had failed in the Great Crusade but with Lady Marianne now leader of the Glaucous Templars, she reaffirmed them in their duty, Even though they all, including herself wanted to die for abandoning her broter and letting him die, they all knew they still had there duty to the Emperor and they would complete there duty before dying or die trying. With Lady Marianne's word, the Legion fiery spirit was burned hot once more where they traveled to Terra and joined Rogal Dorne in the defense of the Imperial Palace. While at first he completely turned them awat but after seeing their determination and there will of fire to protect the Emperor and the Imperium, he agreed working with Rogal Dorne on it's defenses. When the final battle occurred finally, Lady Marianne let Rogal Dorne take control of the Legion during the Siege of the Imperial Palace since he would know better where to deploy them although she continues to lead them on the front. Towards the end of the battle when the Emperor and the remaining Primarches decided to teleport, with the Glaucous Templars hallway to being completely destroyed, Lady Marianne and some of her most veteran Astartes volunteered to go with them and with support with Rogal Dorne, the Emperor agreed to Lady Marianne's request in honour of her brother's name. When they teleported aboard Horus flagship, Lady Marianne and the Glaucous Templars teleported in the same location with the Emperor, Determined to keep the Emperor safe at all cost to make sure he could finish what her brother started years ago, Lady Marianne led her brothers throughout the ship, defending the Emperor at all cost with the Glaucous Templars almost completely destroyed to the last man with Lady Marianne herself mortally wounded but not before using her quick speed and thinking to pushing the emperor out of enemy fire, earning her the title "Lady Marianne the Flash" by the Emperor himself. Eventually the Emperor was forced to abandoned them as they drew close to the bridge and the Emperor forbided the wounded survivors of the Glaucous Templars to enter in the aspect they would most likely be destroyed however they were determined to complete there duty, stubborn to the end watching the Emperor battle Horus at the end of time, knowing fully now they could not help. When Rogal Dorne finally found the few mortal wounded survivors of the Glaucous Templars and the Emperor in a weakened state, Rogal Dorne took them to the Imperial palace where the survivors were treated and the Emperor was laid by his son on the Golden Throne, giving him his final instructions as well as telling him Lady Marianne is a living icon of the Imperium as she defended him at all cost to reach Horus, almost dying for him. Following the Emperor entering Stasis and the ending of the Battle of Terra and eventually the Hersey, The Glaucous Templars were almost completely destroyed to the last man as only a few hundred remained but by this point they no longer wore the colors of their legion, instead everyone took up the Emperor's Champion vow set by Rogal Dorne. By the Second Founding and the true end of the Hersey, a portion of the remaining Glaucous Templars had honorably committed suicide in an attempt release them from their hell and to be with their Primarch once more in spirit while nearly halve of the remaining Legion joined the Imperial First and helped formed the Black Templars under the original Emperor's Champion command. The other half led by Lady Marianne the Flash now declared a Saint essentially donned their Legions color's once more and entered exile permanently, beginning the first Penance Crusade into the Eye of Terror in hopes to gain their honor and forgiveness from there primarch and there Emperor but before Lady Marianne said her goodbyes to Rogal Dorne whom now at this point looked at her as a little sister who wanted to protect her but he knew he could keep her here for she is stubborn as her brother ,Janusch Feuer. Before departing, Lady Marianne requested that all records of their Legion be destroyed since in there eyes, they had failed her brother and the Emperor and with the Legion now completely gone now essentially with most now in the Black Templars, committed suicide or have joined her in their final crusade against Chaos, there was no point. After saying there farewells, He watched as Lady Marianne and her Templars board there thunderhawks, as they boarded however, a golden aura began to flicker around their bodies. Rogal Dorne kept good on his word and had the Glaucous Templars completely erased from history. In the 41st millennium, most historians and chapters simply see the Glaucous Templars as a second founding chapter that was destroyed quickly afterward by Chaos remnant forces from the Hersey and Saint Marianne is a mysterious Saint with almost nothing known about her but telling how she boarded Horus flagship and almost died defending the Emperor but is considered myth in the same matter as Ollanius Pius.

Thanks! And yeah, the point thing is kind of a mess at first. At first the idea was to just do 4-5 campaigns in the Great Crusade, 2-3 in the Warmaster Crusade and 1-4 (depending Itssvan and stuffs) for the Heresy instead of points, and then just make a rolle to see if the primarch was at the important events or not. But the people I used the RNG with wanted to look better and have more campaigns and stuff depending on ow good things went for their primarc, so the point system just came to me. But if you think its more easy I could easily change it if you want.

Also yeah, there is a few things that I didn't work a lot on (like stuff for legions that lost their primarch). Personnaly, I think that I also overlook the chaos in favor of the Loyalists in the Horus Heresy and Aftermats, but I just didn't have any ideas for them. If you tink of anything, I'm open for improvements.

Also, Rogal Dorne as friend AND Horus as enemy! Your were destined to be loyalist. Really interesting guy by the way. Way better than my Legion II Primarch, who was just a megalomaniac moron.

Thanks, I'll finish that lore on that Primarch prob later, It's prob the most developed II legion i've made so far lol

As to make it easier, prob just go with dice Rolls like how most Creation tables instead of going with a score point system like here

https://www.heresy-online.net/forums/...generator.html
(Baron Spikey is the best lol)

or here

https://1d4chan.org/wiki/Space_Marin...reation_Tables

examples

for actual idea's to add, maybe there combat doctrine and did they do Special like my Legion were blanks designed to fight rogue phykers and chaos itself in secret, what chaos god did they allied with and what did they do become there champion? you should also make it where the Legion can Fudge up to the point where they get destroyed or disappear during the Great Crusade to -_- those Lore fanatics happy, you don't want this labeled Heretical lol

Perhaps add companions or advisors for the primarch such as Luthur to the Lion or Marianne to my Primarch

maybe there position in the Imperium during the Crusade and Hersey like Horus was Warmaster

Can't think of any at the moment, maybe pop a question in the forums for help, even though it's frown upon at a table top game, people have no problem coming up with lore for the unknown legions lol, maybe send Baron Spikey or another vet here who knows alot for idea's.
