You won’t meet any of these fairies in the first book. They are the less human looking fey. They include trolls, goblins, pixies, leprechauns, kelpies, all those other fairies. These fairies live in Tir na nOg as well, but they inhabit the Primeval, the ancient forests surrounding the Jewel Kingdoms. On the whole, they are wild and unpredictable, too uncivilized for the Shining Ones to allow into their courts. I’ll be introducing them in later books, for now it’s enough for you to know they exist.
