House Caswell of Bitterbridge

Casa Caswell de Puenteamargo

House Caswell of Bitterbridge is a noble house of the Reach, sworn to House Tyrell, seated in the bridge-town that gives it its name and that guards one of the crossings of the Roseroad. Under a golden centaur with a drawn bow, its lords have been pulled again and again into the great wars of succession that have shaken the Seven Kingdoms, almost never by choice.
