Appearance.

(The only canon image of Erda is in black and white. Shes alos covering her hair and half her face so sorry if my description of her doesn't match how shes described in books. Blame the image not me.)

Shes 1.6 metres tall. She weres black robes and sandles. She doesn't where a hood in this timeline since shes not in hiding. She has light skin and has short black hair. Shes on the sender side but clearly has some curves. Her tits and ass are decently sized.
