Zethenna--She is the daughter of The Wizard Verthanda and likes to be called Her Wizardness and wear frightful, living earrings.

From Wizard Girl:

Her skin was a powdery white; her lips a pale blue and her eyes the translucent blue of icebergs. Her most striking feature—aside from those poisonous earrings—was her hair. It was like the angel hair Monica swirled around ornaments in cut glass bowls every Christmas to make centerpieces. White would do if you described it by color. It was really lighter than that, nearly transparent. Her hair grew down in a V right down her forehead with the point nearly touching the bridge of her nose. It also grew thick all the way down the back of her neck until it disappeared beneath her white robe and in thin sideburns along her jaw line almost to her chin.
