"I can tend your flight-rock, Captain Twig, if you'll have an old bag of bones like me."

Molleen was an elderly banderbear with a missing tusk. She met Rook at the Great Convocation of Banderbears and went with him aboard the Skyraider on his quest to free Cowlquape Pentephraxis from the Tower of Night, because she had experience as a Stone Pilot. Later, on the journey from Undertown to Free Glades, she was drawn into the Twilight Woods and was lost forever.
