Aed, or Aodh, is the prince of the Daoine Sidhe and a god of the underworld in Irish mythology. He is known from inscriptions as the eldest son of Lir, High King of the Tuatha de Dannan, and Aoibh, a daughter of Bodb Dearg. Aed is elsewhere described in the Dindsenchas as being the Dagda's son and brother of Cermait and Aengus killed by Corchenn of Cruach for seducing Corchenn's wife.[1][2]
