The Chamber

"``See this as a sand box type of place. An infinite place of infinite possibilities that all can be acted on upon here in infinite ways. ``"

Overview
The Chamber is a reality created by "Sans the Skeleton", with the sole purpose of acting out certain events in a timeline, or verse without truly, and permanently affecting the said timeline, or verse. The Chamber can be correlated, and compared to a Sandbox Scenario, as the multiverse can also be used to perform hypothetical events, and decisions. Actions that have been executed in The Chamber are only theoretical, and speculative, as like stated above, do not affect the said genuine timeline, or verse that is being acted upon.

Rather than a reenactment, it's more of a way to play and alter verses and do whatever without effecting the original course. That'd be playing God, after all.
