From the publisher:

Beneath the surface of the graveyard, ghouls have dug a network of tunnels where they can plunder the buried dead. This set of 25 six-inch-square tiles details narrow earthen passages clogged with roots and littered with broken caskets and bones. Even stonework burial vaults have been breached by the relentless digging of the hungry ghouls. Bonus tiles in this set include two Graveyard entrances where adventurers can access the depths of this undead domain.
