First off here is the relevant rumor from yesterday discussing psychic powers.
-There will be at least 4+ "Disciplines" of Psychic Powers in the game. (WFB has 8 lores)
-Disciplines seem to fall roughly along the lines of the sects described in the novel "A Thousand Sons" as used by the Heresy-Era chapter.
