In another related story, "Aided Derbforgaill" ("The Death of Derbforgaill"), the Scandinavian princess Derbforgaill, whom Cú Chulainn rescues from being sacrificed to the Fomorians in some versions of "Tochmarc Emire", comes to Ireland with her handmaid, in the form of a pair of swans, to seek Cú Chulainn, with whom she has fallen in love. Cú Chulainn and his foster-son Lugaid Riab nDerg see the swans, and Cú Chulainn shoots Derbforgaill down with his sling. The slingstone penetrates her womb, and to save her life Cú Chulainn has to suck it from her side, but since he has tasted her blood he cannot marry her. Instead, he gives her to Lugaid, and they marry and have children. One day in deep winter, the men of Ulster make pillars of snow, and the women compete to see who can urinate the deepest into the pillar and prove herself the most desirable to men. Derbforgaill's urine reaches the ground, and the other women, out of jealousy, attack and mutilate her. Lugaid notices that the snow on the roof of her house has not melted, and realises she is close to death. He and Cú Chulainn rush to the house, but Derbforgaill dies shortly after they arrive, and Lugaid dies of grief. Cú Chulainn avenges them by demolishing the house with the women inside, killing 150 of them.
