Zoroaster, also known as the "Great Death", is a country located in western Somnus. It is known by its nickname due to the fact that the entire country, which appears to be a mostly desert habitat, is completely devoid of life, while ships have been known to shipwreck in their attempts to both step foot on or leave the island. Some eager adventurers and explorers have never returned, with others often going insane about their experiences.
The Zoroastrians, the island's inhabitants, resembled black ape-like humanoids that possessed bat-like wings and white or grey stripes on their arms and legs. Most of them were wiped out by an unforseen event. It is unknown why some rare cases, such as Sarkies, are still alive.
