“Morgaine was not tall; she would never be that, and in these years in Avalon she had grown as tall as she would ever be, a scant inch taller than the Lady.  Her dark hair was plaited down the back of her neck and wrapped in a deerskin thong; she wore the dark-dyed blue dress and deerskin overtunic of any priestess, and the blue crescent shone darkly between her brows.” (138)

 This is an early vision of Morgaine, through Viviane’s eyes.  Morgaine is often
very concerned with her appearance because of how different she looks from Arthur’s men.  Gwenhwyfar mocks her small stature and dark skin, and calls her a Fairy, even as she attaches herself to Lancelot, also small and dark.  Another symbolic double standard of Christianity.
