Cath Maige Tuired: The Second Battle of Mag Tuired (Author: [unknown])

section 85

Then she told the Dagda that the Fomoire would land at Mag Céidne, and that he should summon the áes dána of Ireland to meet her at the Ford of the Unshin, and she would go into Scétne to destroy Indech mac Dé Domnann, the king of the Fomoire, and would take from him the blood of his heart and the kidneys of his valour. Later she gave two handfuls of that blood to the hosts that were waiting at the Ford of the Unshin. Its name became 'The Ford of Destruction' because of that destruction of the king.
