A Temporal Fold was a major disruption in the natural fabric of time in order to move an object or being into another moment in time. Only extremely powerful beings like The Oracles, the Senior Partners or D'Hoffryn, one of the so-called Lower Beings, could create temporal folds. Mortal magic practitioners could create smaller temporal folds through a ritual invocation to the god Eyrishon. Those who performed and those moved in time through the temporal fold usually mantained their memories.
