The Isle of the Dead is a location in the Diamond territory and was the hiding place of the Sister of the West.
Geography
The Isle of the Dead is a tall, rocky spire located just to the west of Blood Lily Island. It is the most western point in Deltora. There is a cave near the peak of the Isle that has almost always served as a den for Kobbs, but they were forced out of the cave when the Sister of the West was hidden inside it. After the Sister was destroyed, the Kobb reclaimed the cavern. Countless generations of Kobbs moving over the surface of the Isle has coated it in slime, giving it a slippery, shining surface. The waters around the Isle are very rough and turbulent, making them dangerous for ships.
