Temporal causality loop

A temporal causality loop (or simply temporal loop) is a special condition of time, in which time runs for a certain period, then resets itself to a point back in time, after which the events play out over again.

• However, afterimages of previous loops can be found to have effect on the dekyon field. This causes humanoid lifeforms to experience déjà vu.

A causality loop can be caused by an antimatter explosion in close proximity to a temporal anomaly.

This phenomenon can sometimes be referred to as a "pocket universe."
