House Oberigo is one of the most powerful noble families in Cheliax and closely associated with the ruling House Thrune. They are led by Eirtein Oberigo, the current patriarch, and are served by two minor noble families: the Aulamaxas and the Ghivals. The walled estate of Vira Oberigo in the former capital of Westcrown has been the family's primary holding since the Four Families Siege, and they control nearly everything on the Wiscrani island of Siraon.
