Beowolf is a giant monster, and Count Geoffrey's pet. He is apparently very ferocious, as the skeleton of a carnivore has been seen in his room. Beowolf is never seen, only his shadow is.
It is unknown what became of him when Castle Threadbare sank into the moat due Geoffrey falling victim to the curse of the chain mail letter.
- Beowolf is a reference to the legendary Geatish hero, Beowulf.
