Castle Panteer, situated in the Glarus Valley on Alderaan, served as the original family seat for House Panteer. Around the time of 3653 BBY, following the demise of both Queen Silara Panteer and her heir Gaul Panteer, the soldiers of House Ulgo launched an assault on the castle, igniting it with fire and compelling House Panteer to seek refuge in mountain caves. Subsequently, Bouris Ulgo, who declared himself king, along with his army, took control of the burned castle's remains.
