Cú Chulainn
After a particularly arduous combat Cú Chulain is visited by another supernatural figure, Lug, who reveals himself to be Cú Chulainn's father. Lug puts Cú Chulainn to sleep for three days while he works his healing arts on him. While Cú Chulainn sleeps the youth corps of Ulster come to his aid but are all slaughtered. When Cú Chulainn awakes he undergoes a spectacular "ríastrad" or "distortion", in which his body twists in its skin and he becomes an unrecognisable monster who knows neither friend nor foe. Cú Chulainn launches a savage assault on the Connacht camp and avenges the youth corps sixfold.
