Eógan

King of Munster. Eógan was the son of Ailill Aulomm and grandson of Eógan Mór.

His mother seemed to be the sun goddess Aine, whom his father had raped. Eógan was brought up at the same time as his foster brother, Lugaid Mac Con, who was also his main rival and enemy in later life.

Their rivalry came to a head when they both heard music from a yew tree that hung over a waterfall. Both wanted the music-maker which belonged to Fer Í, son of Eogabal and brother of Aine. Fer Í vanished before either one could have him, but the son and foster son of Ailill ended up challenging one another to a battle at Cenn Abrat.

Eógan won this battle, and he thought he had killed Lugaid. Instead he had killed Do Dera, his foster-brother's fool, who looked exactly like Lugaid. Lugaid escaped with 27 of his men to Scotland. Upon the king of Scotland's discovery of Lugaid's true identity, the king promised military support to make Lugaid king of Munster.

Eógan received aid from Art Óenfher, his uncle and the High King of Ireland. He met a blind druid named Dil Maccu Crecga, who knew immediately that the king of Munster would not survive the second confrontation with his foster brother. Dil advised the king to sleep with his daughter, Moncha, who conceived a son, Fiachu Muillethan, who would later become king of Munster.

As foretold, Eógan and Art Óenfher were killed at the Battle of Maige Mucrama, and Lugaid Mac Con became king of Munster.
