Oathsworn Castle rises upon a mountain peak overlooking the wild lands of Llydaw, a fortified city of halls, homes, workshops, and gathering places beneath the banner of the Golden Stag.

At its heart stands Ravenhall Castle, the Inner Castle and ancestral seat of House O'mara. Within its walls lie the High Seat and Halls of the Oathsworn, where the legacy of Ravenhall endures and the affairs of Oathsworn are held.
