Dominic Thompson becomes an infernal dungeon core and is given one task: make his dungeon renowned throughout the world by killing adventurers in the most gruesome ways possible.

With this new power, he infuses his soul with a Tainted Elf avatar so he can walk among mortals. To become the greatest, he must make the other dungeon cores submit to him. And that means shattering their jeweled hearts.

Or seducing their avatars.

Lucky for Dom, the dungeon’s avatars are beautiful monster girls. But they’re also the fiercest warriors in the realms, and there’s a fine line between murder and seduction.

This dungeon core story contains light LitRPG and harem elements.
