"What business does a librarian knight have at the tally-huts? Speak, wretch, or my sister here shall feast on your liver!"
-Mother Muleclaw

Mother Muleclaw the Second was Roost-Mother during the first two books in the Rook trilogy. She controlled the Great Mire Road, and, with it, all trade between Undertown and the Deepwoods.

Mother Muleclaw, along with her shryke army and General Tytugg's goblins, was devoured by the Rock-Demons in the Great Storm Chamber Library during the events of Vox.
