Viidost Eyzan is a large swamp in the Siginzad valley. Its largest inflow is the Steg Bo river.
Viidost Eyzan is a windy place, with chilling winds rolling down the valley and from the towering peaks of Inzurakthol. Viidost Eyzan is the abode of such creatures as green hags, thouls, greater medusa, oozes, black dragons, and trolls. The swamp gets its name from the poisonous plant Asoron Husk that grows like a weed in this area.
