Warhammer Fantasy Skavenslayer Gotrek & Felix #2 Black Library William King 2003
Gotrek & Felix return to the city of Nuln to lie low and gain some steady employment. Being a sewer-jack would seem to be fairly mnudane work until the skaven raise their furry heads.
The maze of sewers provides a perfect staging post for the foul chaos rat-men, as they seek to overwhelm the city.
Luckily there are two people below ground who like a good fight.
