Canonfire!

I dont know how many of you read manga (or like it at all), but there is a number of fantasy-based mangas around, and Dunegon Meshi (Delicious in Dungeon in english) is a very good one. Part humor, part adventure, it tells the life of a adventurer party that after (barely) getting out of a Castle Greyhawk-like mega dungeon with almost no funds, they have to get back inside it living off the dungeon itself.

The history, while light-earthed, and some very good story turns, and they author really gets the atmosphere of a mega-dungeon, and eve create some monsters that i plan to steal for my current campgain in Greyhawk.
