Temporal pocket

A temporal pocket was an area or section of space that had its point of relative index offset from real time and continued from that point. For instance, one could stand in an area where something that was in a temporal pocket actually stood, but it would not be there. The only way to find something that was placed within a temporal pocket was to change one's point of index to the same as that of the object, and continue at the same relative velocity as the object itself.
