They came down from the sky in dark ships...

There are some extremely ancient traces of folklore, before things were written down, of a strange, beautiful very tall race of beings that came down from the sky in "dark ships." (cloaked ???). They were said to be a vastly superior sophisicated race who upon seeing from above the very green and isolated island Eire and it's simple sparce native population decided to settle there. They were the "Children of Danu," the Mother Goddess, the Tuatha de Dannan, (The Tribe of Danu).
