From White Wolf Game Studios' Vampire: The Masquerade role-playing game. This discipline grants vampires of the True Brujah bloodline control over time. The discipline of Celerity is in actuality a cheap copy of this more versatile and powerful discipline. With this discipline, skilled True Brujah can cause time to stop, call up the past, outrun anyone using Celerity, and cause people to enter temporal recursion.
