From the publishers blurb:
Enter the Carnivorous Caverns: An OSE Adventure for Levels 2-4
Beneath the earth slumbers an ancient, sentient cavern system that feasts on souls. When it awakens, it lures its prey with a false village that appears out of nowhere—its streets filled with eerie, hollow-eyed villagers clinging to fragmented memories. Nothing in the village is real, yet everything conspires to drag adventurers into the depths.
In this Old-School Essentials adventure, players will face:
A decaying, surreal village that acts like an angler fish's lure.
Replicated villagers who are increasingly frantic, distressed, and violent as their artificial existence collapses.
A living labyrinth of flesh, filled with dangerous creatures, twisted passages, and grotesque traps.
Will your party survive, or become another flesh template for the Caverns' ever-hungry traps?
