Along the way, they encounter injured wildlife and panicked bugbears. Terrifying storms beset the region, raining down acid and oozes. Agreeing to investigate the small corrupted lake, the adventurers discover a long buried evil has awakened—bringing with it oozing undead. The party must navigate the wilds, face the ooze storms, and confront a reanimated warrior who betrayed her god.

The heroes arrive at the eponymous Keep on the Borderlands, a fortress on the edge of civilization built to stave off the chaos and evil of the wilderness. Using it as a home base, a party can make forays into the surrounding wilderness, encountering monster and marauder alike. The centerpiece of the adventure is certainly the CAVES OF CHAOS, a network of tunnels and caverns found in the walls of a nearby but isolated ravine. It is here that hordes of evil humanoids have made their home. Through combat and negotiation, the players can try to explore and map out these caves, perhaps with the aim of accumulating valuable treasure or even cleansing the land of evil creatures. However, even the Caves are not all they seem. Beyond the goblins and kobolds lurk dark horrors: cults dedicated to fiendish chaos and a Minotaur's enchanted labyrinth await the unprepared adventurer. But for the hero who is brave, clever, and fortunate in equal and sufficient measure, great treasures and glory await in the Caves of Chaos that lie beyond the Keep on the Borderlands! TSR 9034
