In a world where dungeons existed, explorers and crafters were competing to become the very best. They were collecting the best cards and creating the best combos in order to conquer parasitic dungeons, kill dangerous monsters, and bring out new inventions to make the world a better place.

Those two jobs were the most popular jobs in the world. If one could become an explorer or crafter, one could become rich easily. However, these two jobs were also the most dangerous jobs ever as dungeons weren't something to be trifled with. Many people died inside dungeons before they could achieve their dreams.
