Spektran

Description
Spektran is a lone island in the ocean, north of the Isle of Deeds and south of Buccaneer's Den. The Isle had formed from shallow waters in the ocean, and the only building on it is the home of the mad "Sultan of Spektran", Martingo, a crazy, but harmless man, thinking himself to be a king.

Spektran hadn't formed by Ultima IV, but the Bell of Courage was found in its waters. In Ultima V, the island housed the hut of Sutek the mage, while in Ultima VI, the treasure of Captain Hawkins was found there. By Ultima VII, the Sultan had build his house.
