Dungeon Ssibeomeongneun Artifacts

A dungeon-guiding gig goes sideways for explorer Stetch Atelier when the prince who hired him tricks him into activating a fatal curse. But instead of staying dead, Stetch is resurrected by a sentient artifact that offers him a deal that may help him get his revenge. To hold up his end of the bargain, Stetch sets off on a long journey of raiding dungeons, slaying monsters, and making new enemies and friends along the way.
