Odrosal

Odrosal is one of the Red Mountain Citadels. An old Dwemer fortress, Odrosal is now named after the residing Ash Vampire Dagoth Odros. It is inside of the Ghostfence and marked on your world map. This is the place where the Keening Artifact can be found during the Main Quest. The ruins are divided into two different areas: the Dwemer Training Academy and the Tower.
