Bone Reaper

Long before the crypts were sealed, their keeper made a bargain: no soul entrusted to him would ever be taken. When grave robbers breached the burial chambers, he called upon the spectral realm to help him keep that oath. It answered, and collected his life as payment.

Centuries later, the Bone Reaper still walks those corridors. The amber seal within his chest holds the souls he swore to protect, and through it he hears every disturbed grave, every stolen relic, every whispered rite meant to wake the dead.

He follows trespassers beyond the crypts, however far they flee. Those who return what they stole sometimes survive. Those who refuse are brought back to fill the empty graves.
