The Five Corners is a realm containing a single room. Legends tell of this room, which has a gate to Enlightenment made of agate, ivory, nickel, and painted indigo; a gate to Terminus, made entirely of onyx; a gate to the Cenotaph, made of grey bones and onyx and lapis lazuli and sienna wood; a gate to the Dominion, made of copper and gold and sulfur and sard and pallid stone and viridian wood and velour curtains; and a gate to Elysium, made of light. None have ever seen this place, nor the planes it connects to.
