“Faeries, like the djinn, preceded humanity as a sentient race that inhabited the earth. In Irish lore, the original fairies were the Tu-atha De Danaan ("the people of the goddess Danu"), said in some accounts to be directly descended from the gods. The fairies took up residency in Ireland, and possessed supernatural and magical powers. Over time, they lost battles to invaders and used their powers to retreat into the earth, into a parallel world where they could remain invisible and undisturbed.”
