I made an effort during this RP to not make many long-term plans. This is part of the reason why the updates took me so long to write, other than trying to stay true canon as much as possible. After each set of posts I went in whatever direction seemed best according to all the information I have on the events that transpired on Isstvan III, and depending on what the players decided for their characters. I did my best to stick to the timeline of events probably more than anything, such as how much time passed before the first Traitor forces landed in the city, the seeker and biker squads being deployed, the storms rising, the Titan footsteps, etc.
Tarvitz's path on his way through the city is pretty detailed, so I did not plan on the players finding him initially, but a lot of time passes in the books once he returns to the Palace. The scene where Lucius decapitates the Chaplain is like, weeks or maybe even months I can't remember at the moment, after the virus bombing. So, if the players did make their way back to the Palace at some point, they likely would have found him there.
You can never be prepared for the unexpected
