That the Warp can have an effect on the passage of time is well known. It is a phenomena experienced by those starship captains who have travelled short times in the Immaterium, only to arrive at their destination and discover standard centuries have passed in the rest of the galaxy. Less known and understood are those few psykers who use this aspect of the Warp to twist time to their own ends. Conventional wisdom of the Calixian representatives of the Scholastica Psykana holds that such psykers simply "speed up" or "slow down" the perceptions of themselves and their fellows, rather than actually manipulating the flow of space-time. Perhaps they can also see glimpses of future events, granting them a far better chance of success in certain actions, but no more. Their arguments are unconvincing, though the majority of the Calixian Conclave of the Inquisition accepts them -- perhaps because the potential ramifications of the alternatives are too terrible to contemplate.
- Precognition - One aspect of temporal manipulation that most often manifests in psykers is the ability of precognition -- an ability to see the myriad possibilities of the future. Even the strongest psykers can only see the possibilities of the next few moments of their life, and even then, only for a brief instant. However, that can often be enough to make a difference.
- Stasis Shell - The psyker creates a spherical area in which time seems to completely stop, leaving whatever is inside perfectly frozen in time. When the effect ends, the occupants do not realise any time has passed. The psyker selects a spherical area roughly three metres in diameter that is within range of his power. Anything fully within this area is effectively frozen in time, and may not take actions, move, speak, or do anything. In turn, however, they may not be harmed or affected by any means. Anything outside the area of the stasis shell may not enter or pass through the area affected by the shell, which is treated as an invulnerable barrier.
- Warp Time - The most powerful psychic adepts of the temporal arts are able to speed and slow the passage of time, both for themselves, their allies, and their enemies.
