Gnometown Hero
Fafhrd and the Grey Mouser have a very famous rat adventure, but it's not remotely a "go kill rats in the cellar" adventure. It is closer to Alice in Wonderland, if Alice was having sex with mice in Wonderland. (Leiber knew what he liked, you gotta give him that.)No, think it started with WFRPv1. It had The Rat Catcher and small dog, which set it off. Plus Skaven! Just cool villains with great background. But think Fafhrd and the Gray Mouser may have had a story with Ratmen in it. If you are talk just giant rats, H.G. Wells Food of the Gods. Plus the Nutcracker.
