This magical librarian is so mannered and sweet she could practically be a princess, but she's not. My lawyers tell me it's important to make that clear. Her auburn hair is braided into a smart up-do. She wears half-moon specs and a yellow french-style Victorian era dress - bodice, puff sleeves, the works! A bit outdated by contemporary standards, but then again, Beau lives in a place older than time.
Beau guards the Library of the Fair along with her faithful if less well-mannered companion, The Beast. An aspect of the Cave of Wonder, she is a powerful spell-caster. Woe betide those who disturb the quiet of the library. Sssh...
