I recently finished Carcharadons: Red Tithe, and was intrigued by the various hints at their origins. I know people seem to think they are Raven Guard descendants, but the novel seems to indicate otherwise. The beauty of reading on a Kindle is that I can highlight various quotes, and find them easily later, so I'm going to put out some of the quotes, and see what people think. Hopefully we can get a decent discussion going, something that's been missing in the fluff boards for a while.
[H]e was able to blend instinctive blade work with the close combat savagery that was the genetic inheritance of the Carcharadons.
While they are renowned for many things, close combat savagery has always been more associated with SW, WE or BA. This is one of the first things that made me think of something other than RG.
The Blindness beckoned, that silent, suicidal ennui that made up one of the darkest parts of his chapter's twisted genetic inheritance.
Yes, RG and their primarch are pretty emo, but I don't recall it ever having been mentioned that they had a condition similar to the Butcher's Nails or Black Rage. There is no indication of implants though, or a mass insanity that overcomes the likes of the Death Company.
These loyalists were unlike and he'd encountered before. They bore a curious resemblance to the Night Lords themselves, but where the VIII Legion delighted in the terror they caused, these grey killers seemed to be without any emotion at all.
The Sharks fight in total silence, no war cry or bellows of rage. Nothing too specific there though.
Sharr's Chapter had left humanity for the emptiness of the Outer Void when He [the Emperor] and they would not return until He did so once again.
They were banished while the Emperor was alive, so could they possibly be descended from survivors of one of the missing Legions? A stretch, I know.
Only with the coming of the Forgotten One could the Edicts of Exile be overturned, and the Chapter's eternal crusade in the darkness be brought to an end.
Again, is this one of the missing primarchs that they are waiting on? We know now that Primarchs are making a comeback, and while GW refuses to engage with any discussion about them, even reining in the BL authors from dropping hints about them, it would open a whole new angle to bring one of the missing back.
When they had first been banished, none had expected them to survive, let alone remain united as a chapter. But survive they had, their disparate heritage bound by their faith on Him on Earth. Nothing could shake that.
"Disparate heritage" immediately set me thinking that they were a combine of loyalists from the various traitor legions, or the remains of the Crusader Host, that were banished to an eternal exile. Along with the previous mention of the "chapter's twisted genetic inheritance" I like this idea best.
The Blindness burned away his thoughts, demanded he sell himself...
Again, more a BA or WE trait than any other.
...his pale features streaked bright red, panting as he quenched the manic frenzy that was his genetic inheritance.
The Pale Nomad [Te Kahurangi, the Chief Librarian of the Carcharadons] was also, according to Bar'ghul, his brother.
Bar'ghul is a demon that the NL sorceror in the story consorts with. Could he be descended from NL geneseed?
Down in the depths of the White Maw, the Greats slumbered. There were three of them, three Wandering Ancestors, their bones reduced to ossified cartilage, sealed away for eternity in the adamantium shells of their Contemptors.
These guys were either interred or are at least alive before even Bjorn was interred, by all accounts, if they were actually exiled while the Emperor was alive.
The White Maw itself was, at its most basic levels, a venerable Exile-Era Tyrant Class Capital Ship. The Original design had been both rebuilt and expanded down the centuries. New engine blocks, plasma recyc systems, triple-admantium bulk heads. The White Maw was a patchwork monstrosity, its capabilities more akin to the Battle-Barges of more standardized Chapters. Her six escorts likewise displayed the broadest range of class variation imaginable from the retrofitted Sword Frigate "Grey Harvest" to the Crusade-Era Wrath Hammer "Void Revenant" - more than half the fleet had been in service since The Day Of Exile.
All preHeresy classes of ship, and would be considered relics if they are as old as they seem.
So, my personal opinion is of a chapter made up of loyalists from traitor legions, and down the years various geneseeds have been mixed and matched, leading to hybrids of the various legions. They have a physical defect that appears as they get older, the description of of which sounds like their skin becomes almost shark like in patches, which could be the result of the combining of geneseeds.
What are people's thoughts? Am I looking too much into it all? Is there any merit to my conclusion?
