Nothing is beyond the reach of the Obsidian Ridge.
No one has laid eyes on the Obsidian Ridge in over a century. The floating mountain is a legend, lost in the dustiest tomes… until it appears as if from nowhere over the kingdom of Erlkazar.

Driven by the madness of its master wizard, the Obsidian Ridge will destroy everything in its path until the wizard gets what he wants: the princess of Erlkazar for a bride. But deep in the tunnels of the Obsidian Ridge, a room of trophies attests that he wants a great deal more.

The citadel has hunted such quarry before.
