After Brin Crownsilver's father was assassinated, she was assigned to look after him. Constancia and Brin were placed in the same Tormite monastery where Constancia apparently flourished although Brin was unhappy. In 1477 DR, Brin ran away from the monastery to the Sword Coast. Although Constancia chased after Brin in an attempt to bring him back, she was charged by the Tormites with dereliction of duty because it was her responsibility to keep Brin safe. Constancia was eventually caught by a trio of bounty hunters lead by the dragonborn Mehen and was returned to Cormyr in 1478 DR.
