Wilhelm the Worm is a Nord residing in Anvil. He is allowed to sleep in the Harborside Warehouse, in exchange of keeping the rats away. People have given him the nickname "the Worm," due to his uncaring nature about filth.
Anvil: "Nice, friendly folk in Anvil, even the Countess greets me in the street. Well, except for that Newheim the Portly. He's a mean old scroat."
