Calvin was a lone mole who tunneled through the ruins of a broken world. Until he discovered a decommissioned nuclear bunker—abandoned, sealed, and long forgotten.

Buried deep beneath the surface, it became his home. More than shelter, it was his den. His labyrinth. A quiet kingdom of rust and wire. He slept in the mess hall, mapped the vents, sipped nectar beneath warheads, and found comfort in fruit cans no one had touched in decades.

But within the restricted zone of that bunker, Calvin discovered what was never meant to be found—something ancient. Hidden behind a blast door marked AUTHORIZED PERSONNEL ONLY.
