A literal mountain of black glass, floating impossibly on the sea. Mt. Nomad drifts in the most northerly reaches of the ocean, destroying any life which crosses its path. It was created by a legendary shapeshifter, the Thief-of-Faces, from jewels stolen from a living mountain as a weapon to be used against his enemies; unfortunately, the Thief hates any form he has taken in the past, and he has lived for a very long time.
