Time Mines

Time mines, also called temporal wards or temporal locks, are magickal effects that prevent time travel into a particular time.

A time traveller arriving in such as time without the proper amulets is destroyed by magickal forces. Such unfortunates have been known to disintegrate into dust, burst into flames or simply explode in a shower of gore.

The First Time War is extensively time mined by both Atlantis and Mu. As such, travelling back to that period is obscenely dangerous.
