Uathach

In Irish and Scottish mythology, Uathach was Scáthach's daughter. Cú Chulainn, who had recently arrived at Scáthach's fortress-home to be her pupil, accidentally broke one of Uathach's fingers, and Uathach's suitor, Cochar Croibhe, challenged him to single combat despite Uathach's protests. Cú Chulainn killed him and became Uathach's lover.
