The Tuatha De Danann
Exiled/fled out of TÃr na nÓg as they were of the belief that the only way to avoid the coming destruction of the fairy lands was to invade the human world.
"It is God who suffered them, though He restrained them
they landed with horror, with lofty deed,
in their cloud of mighty combat of spectres,
upon a mountain of Conmaicne of Connacht.
Without distinction to descerning Ireland,
Without ships, a ruthless course
the truth was not known beneath the sky of stars,
whether they were of heaven or of earth.'
