LocationToomoneth, Mephigax, Turgon

Kerriack is a long undersea canyon beginning off the western coasts of Toomoneth Isle. From there it bears northwest for thousands of miles, an enormous canyon, ten miles wide in some places, and numerous side rifts as it if were all a great crack in the world. Kerriack ends near the demon infested isle of Turgon. Before the erection of the Turgon Boundary Ward, dozens of aquatic demons escaped into the undersea canyon, terrorizing and making lairs.

Kerriack is an area of overabundance with marine life attracted to a verdant landscape dotted with underwater volcanoes, great reefs and kelp forests.

The Black Chariot, a god-forged submersible, is said to be magically hidden in this area.
