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

In a dark cell, Rollo Bargamnn, merchant of Thyatis, turns away in disgust from his evil, green-skinned prisoner; capturing this wretch cost a ship and sixty gallant men. Then his heart hardens once more, and he resumes the interrogation. Here, perhaps, he may find an answer to the question that haunts him. What new evil is casting its shadow over the storm-swept eastern reaches of the Sea of Dread? The trading routes are no longer safe. The attacks of the green-skinned "Orcs-of-the-Sea" and the mysterious "Ship-bane" now go unchecked. Once their raids were random, but the influence of some unseen master has made them into an organized menace. Soon the questioning will be over; Rollo will know enough to track the threat to its lair. Then he will need a band of hardy adventurers brave enough to take on the task. You perhaps?

Gray Mountain lies deep in the lush elven forest. The temple there was a haven of meditation and learning - until taken over by an evil cleric known as the Rahib. Far under the mountain, he paces before the temple's great altar. A brown-robed servant rushes in and falls to his knees, trembling at the sight of the Rahib's black panther. "Rahib, adventurers came to the village as the sun rose - the strangers now protect Rahasia." A scowl crosses the Rahib's face. "I must have Rahasia! Attack again tonight." As the servant scurries away, a deep growl rises from the giant cat. Gripping the panther's leash, the Rahib paces again, speaking out loud. "We must dispose of these strangers quickly; the secret beneath the temple will not wait much longer." Note: the setting is unspecified, but certain tie-ins, like the wines, prefigure Ravenloft.
