The House at the End of the World is a magical location used by the heroes in The Redemption of Althalus. Gher can use the house to instantly travel through space and time.

When I say that the House is everywhere, I really mean everywhere. When Deiwos first made it, this room was all there was, and he went out from here to make everywhere else, and he made a door to each of those places. That’s why the House kept growing, and that’s why the doors—not the rooms—are important.
