The lady of Cabrion was a cousin of Arthur. While traveling to Arthur’s court, she witnessed Gawaine being kidnapped by Caradoc of the Dolorous Tower.
She ordered her knights to attack, but they were defeated, and one of Caradoc’s knights came after her. Fleeing into the forest, she encountered Duke Galescalain of Clarence (Galeshin), who successfully defended her against her pursuer.
