Requirement: Cannot have the Blank Talent. This applies even during Character Creation
The immaterium lies just behind reality, outside the perception of most creatures in the galaxy, but you are not most creatures. As a psyker, you are aware of the warp, though you may not understand it. You can access and unleash its tumultuous power into realspace.
Channelling such power is fraught with perils, however, and death is far from the most frightening possibility one might face. When you acquire this Talent, you gain the ability to manifest Psychic Powers (page 158). You can also purchase Advances in the Psychic Mastery Skill (page 98) and the Awareness (Psyniscience)Specialisation (page 93).
When you gain this Talent, you learn one Minor Psychic Power (page 166). Additionally, select a Psychic Discipline (page 160) and immediately gain one power of your choice from that discipline. You can spend 60 XP to purchase additional Minor Psychic Powers or 100 XP to purchase Psychic Powers from your chosen Discipline.
You can purchase this Talent a number of times up to your Willpower Bonus. Each additional time you purchase this Talent, you access a new Psychic Discipline and one power of that Discipline.
