The Proof is in the Paws

I seen 'em! I tell ya's, I seen 'em with my own two eyes! *hic* What? Ya don't believe me, either, do ya? I wouldn't expect the likes of ya to. Not 'til the furry little monsters have their teeth at your throat! If only I could prove what I seen somehow. There's gotta be some way ... Hey, I got it. You! You can help me out, yeah? I ain't got money, but I know I can make it worth your while. *hic* They's got tunnels under the city. They sneaks around and if they catch ya, they'll eats ya! I seen a way in, down under the Screamin' Cat tavern. Cut off their paws, and bring me back a sack of 'em! I'll prove once and for all that Mad Matthias ain't mad at all!

Locate the entrance to the Warpblade Tunnels beneath the Screaming Cat tavern. Hunt down the ratmen and collect their paws as proof of their existence. When you have killed enough of the filthy beasts, return to Mad Matthias in Altdorf.
