“Looking for revenge, Mac Cinnfhaelaidh calls on a leanan sídhe (fairy woman) called Biróg, who transports him by magic to the top of Balor's tower, where he seduces Ethniu. In time, she gives birth to triplets, which Balor gathers up in a sheet and sends to drown in a whirlpool. The messenger drowns two of the babies but unwittingly drops one child into the harbour, where he is rescued by Biróg.”
