- Description in the Mirror: Ziantha in Forerunner Foray:She looked into the cruelly bright mirror, cruel because being so often used to check a disguising makeup, it revealed rather than softened every defect of complexion and feature. There was the real outward Ziantha. And with this hour and her great fatigue, that sight was a blow to any vanity.She was very thin and her skin was pallid. Her hair, from the warm steam of her bath, curled tightly to her head, no lock of it longer than one of her fingers. In color it was silver fair, though in daylight it would show a little darker. Her eyes were gray, so pale as to seem silver too. The mouth below was large, her lips with little curve, but a clear red. As for the rest — she scowled at the true Ziantha and shrugged on her night robe.
