Thedo'thalas

Thedo’thalas (Thalassian for “Hidden Home”) is a sprawling, labyrinthian underworld beneath Duskwood that is inhabited by the Bloodmoon vampyr.

It was constructed by Anub'teris on behalf of its lady, Alytheria Bloodmoon. It is accessed through three openings, one in the Deadmines, one in the Dawning Wood Catacombs beneath the Raven Hill cemetery, and one in the Fargodeep Mine.
