Corebound

A Dungeon Core LitRPG | Forbidden Powers, Fairy Secrets, Living Stone

Corebound
Book Four of the Core Overlord Series

I leveled up. Unlocked a forbidden power. Now the dungeon itself obeys my will.

After crushing another wave of adventurers, Nightshard reaches Dungeon Level 4—and with it, a power long thought erased from the system: Corebinding. The ability to reshape terrain in real-time. No more slow digging. No more waiting. With a thought, walls shift, tunnels vanish, traps rebuild themselves mid-fight.

It’s not just evolution. It’s revolution.

But with forbidden upgrades come Bureau eyes. Twinkle is panicking, adventurers are collapsing tunnels, and a certain wounded cleric is about to change everything.

This time, it's not just about surviving another incursion. It's about redefining what it means to be a dungeon.

Shape the battlefield. Rewrite your defenses. Question your nature.
The Dungeon Bureau is watching—and Nightshard is done playing by the rules.

Perfect for fans of Dungeon Crawler Carl, Reborn as a Dungeon Core, and Benoit the Anomaly, Corebound takes the Core Overlord saga into new, deeper territory—where control of the dungeon means control of reality itself.
