Reingard's Realm

Reingard's Realm is a small, magical pocket dimension created by Jean Reingard to deal with what he calls "troublemakers" - in this case, Andrew Wheatley and Moe Frankfort.

About
The realm was apparently created by Reingard. We know very little else about it other than he put Andrew and Moe in there to stop them messing up his plans.

Appearance
The realm is mostly grey and blue, made of crumbling grey bricks in a deep starry void. It would probably look quite nice if it wasn't created explicitly for the dealing with of Andrew and Moe.
