For eons, conquering dungeons has been the most efficient way to become a strong adventurer. Although not everything is as straightforward as it seems. Several questions have always plagued the minds of those who enter these mythical places of power: why are there so many monsters? Where do the amazing weaponry and heavy gold coins come from? Why does the very air fill with life-giving energies?
Cal has all of the answers to these age-old questions, for a very simple reason. He is a Dungeon Heart, a soul forced against his will into a magical stone. After several lonely years, Cal was able to regain sentience, allowing him to form new memories while slowly growing a dungeon around himself. With help from a friend, Cal learned how to create monsters and traps, increasing his power and size quickly.
When a threat to his existence rears its head, Cal decides that he will do anything to stay alive and become stronger. Unfortunately for treasure-seekers, the fastest way for Cal to achieve his goal…is to eat anyone that enters his depths.
