In a distant world five times the size of planet Earth, dungeons and their dungeon cores have become the top of the food chain.Millions of dungeons inhabit the planet, utilizing the various human kingdoms as a source of much-needed mana to facilitate their own growth; in turn, the humans delve into the dungeons and acquire their own power in the form of Essence, which allows them to develop and enhance themselves in a multitude of different ways.
