Describe Vialle here.

Vialle is Queen of Amber, Random's wife, a Rebman noblewoman of the [House of Lir]?, a Sensitive, good friends with Gerard (she was a great help to him during his Regency) and Llewella and Martin. She is very popular in Amber. She's blind but her [Sensitivity]? compensates to a large degree. As a Rebman and a Lirid, she's probably a minor shapeshifter and sorcerer, possibly a conjuror. She is an initiate of the Glow; the Castle Amber servants have gotten used to her relaxing completely submerged in the baths.
