Uathach

In Irish mythology Uathach was the name of Scáthach's daughter. According to the legend, Cuchulainn, who had recently arrived to Scáthach's fortress-home to be her pupil, had a quarrel with Cochar Crufe, Uathach's lover, because the hero accidentally broke a finger to her. Having been challenged to single combat by Cochar Crufe, Cuchulainn killed him during the fight. Eventually, Uathach became Cuchulainn's lover after that.
