== Description ==
This spell records matter in a set area and resets it when triggered.
Select a trigger such as, "everyone in the area dies," or any non-subjective set of circumstances. This trigger must occur at least in part in the spell's area. When that condition is met all matter inside the spell's area is set back exactly to the way it was an hour before the spell's trigger was met. This can bring back the dead, undo and end prematurely spells, and most anything else needed in order to reflect the area exactly as it was an hour ago.
When this happens a voice indicates to those who triggered the reset that, "The white room has been compromised. Resetting." A vaguely humanoid figure, to whom the voice belongs, appears to those who triggered the reset. She will inform them that she can answer their questions, and is able to answer any 10 questions the caster decided on when casting this spell. These questions usually revolves around the spell itself such as it's function, who casted it, etc. but can be any questions the caster picks.
