I may just be blind, and this might be a stupid question, but I have to ask.
Are there rules for Sorcery anywhere? And obviously, I don't mean the Chaos Space Marine Sorcerers, who are no more sorcerers than Space Marine Librarians are booklenders.
I got it into my head to play a Nurglite Sorcerer, but ruleswise, I can't actually find much on sorcery and before I go digging through the other books other than the Core Rulebook, I thought I'd ask.
It'd be odd if Black Crusade didn't have rules for actual Sorcery, considering that both Dark Heresy and Rogue Trader does.
