Shoreless Isle is an island in the Atlantic southwest of Bermuda, and the location of the former Demon Prison, Zzyzx. It was protected by powerful Distracter Spells and other defenses, which caused many ships to sink near it. This was known as the Bermuda Triangle. It was a sort of paradise, with Zzyzx in the central mountain and a Shrine to the Fairy Queen to the east. The battle against the Demons took place on it.
