His other sons, by his daughter Danand, included Brian, Iuchar, and Iucharba, who killed Lugh's father Cian. As an erec (a recompense fine), they were sent on a quest recounted as Oidheadh Chlainne Tuireann (The Tragedy of the Sons of Tuireann), one of the Three sorrowful tales of Erin. After Lugh had taken his elaborate revenge, Tuireann died of grief over their graves.
