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.
For the complete rumor set on psychic powers.... here is the link
With these rumors in mind, here are those disciplines from the novel. This seems like the direction we are headed.
Corvidae - Precogs: Ahriman was the head Corvidae.
Pyrae - Pyromancers
Pavoni - biomancers: Healers and Fleshchangers
Athanaeans - Telepathy
Raptora - Telekinesis Were able to create Kine Shields for protection
