Unname

From LSWiki

[ Command ] unname this place

A rather powerful ability, Unname allows you to destroy the Name that holds a piece of reality together, allowing it to be consumed by Primal Chaos. Due to the nature of things, however, the place will soon be reconstructed from the echo-images of itself in nearby areas. Things inside the place Unnamed essentially fall out of reality, coming to rest Eris knows where.

Basically, resets a room, and teleports everyone and everything into it into Exoma. Don't be like Ezekyal and do this in front of LH, or people will want to kill you.
