" I am nothing, yes; I am air and darkness, a word, a promise. I watch in the crystal and I wait in the hollow hills. But out there in the light I have a young king and a bright sword to do my work for me, and build what will stand when my name is only a word for forgotten songs and outworn wisdom, and when your name, Morgause, is only a hissing in the dark. "

― Mary Stewart , The Hollow Hills (Arthurian Saga, #2)
