The Dead End

Long ago, a powerful witch created a dungeon with a terrifying curse, then retreated into its depths. Any who fall within its dark, stony halls are cursed with undeath. Before long, they become nothing but a mindless, shambling creature. However, the dungeon also brims with treasure, a siren call to adventurers from all over the land. The only way to survive the curse is to rely on Rescuers, a band of "human recovery agents" charged with plunging into the depths to pull out fallen adventurers.
