From the back of the book:
Pulled from the pages of gamer-favourite Dungeon magazine and collected here for the first time are the first 25 chapters of Kyle Hunter's cheeky fantasy romp, Downer.
Once disgruntled dungeon guard Downer Tarantula abandons his post, all hell breaks loose in the mad underground kingdom he calls home. Follow the dark elf merc and his misfit friends as they fend off invaders from both the surface world and the dark realms below, with all of the chaos converging on a bizarre relic stolen by Downer.
Also included in this volume are selections from the artists sketchbook, a gallery of more than 100 monsters, and a detailed map of Downer's home -- the underground city of Oubliette.
