I'm thinking it would be an interesting thing to have happen in my game. I'm not at all clear on how to represent such a thing mechanically for player use. Thoughts?
I know that False-men and Schismaticals are in the old Creatures Anathema book. One of my unaligned PCs is basically an arch heretek and just reached 100 Infamy but has ~17 corruption, I was thinking of letting him ditch is full conversion body for the ship instead of waiting for him to build up the necessary corruption to become a Daemon Prince.
