Dungeons are dangerous, unpredictable death traps that have cost countless adventurers their lives. They are also the only source of magical crystals, the fuel that powers most aspects of civilization. Enter the Department of Dungeons, a continent-spanning organization dedicated to policing dungeons for optimal returns. Less death, more gains. Dungeon Inspector Badger and his junior, Ferrisdae, travel from dungeon to dungeon performing their duty for the safety of all. Not long after Badger takes his apprentice under his wing, they're called in to undertake a dangerous mission. The Land Pirate Raitheus Razorbeak has gone rogue, and it's up to our intrepid inspectors to destroy his dungeon once and for all.
