Twiggly the Gnome said:The Snow Queen is one of the Ælfin. In appearance she has a stoic elven beauty; with long white hair, alabaster skin, piercing blue eyes, and the tail of an arctic fox.
The Snow Queen's consort goes by the name of Mor Hirgon. His appearance is as dark as hers is light; with ash gray hair, skin the color of pitch, eyes like glowing embers, and the feet of a crow. He is said to be the progenitor of the drow.
