The horse was the property of the sea-god Manannan mac Lir, but provided to Lugh Lamh-fada (Irish: Luġ Lámhfhada) to use at his disposal.
[5] Welsh scholar John Rhys thought the name meant "she had a bird's head", and evidently considered it a mare.
[10] In the romance Oidheadh Chlainne Tuireann (OCT, The Fate of the Children of Tuireann), the Tuatha Dé Danann oppressed by tribute enforced by the Formorians gather an assembly on a hill, and Lugh arrives among an army of the "Fairy Cavalcade from the Land of Promise" (Irish: an Marcra Sidh ó Thir Tairrngire).
The horse was quicker than the "naked cold wind of spring", and could travel over land or sea with equal ease.
He is the horse of Manannán mac Lir and is responsible for removing the main character, Quinn MacKenna, from the Otherworld and taking her to Fae.
