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

Anandak, a red dragon, has taken over an abandoned dwarven stronghold as his lair. He has also assembled together a rough confederation of monsters to act as his bodyguard. Anandak is preparing to enter into an alliance with the Black Prince, the March Lord Draven. The plan is for Anandak's monster allies to terrorize the lands north and east of Knacker Knob while the Black Prince, on pretext of marching to the aid of Knacker Knob, take control of Knacker Knob and the surrounding region. An emissary from the Black Prince, Lord Gonzaga, is currently in the dungeon, and he is in possession of papers that might reveal the Black Prince's treasonous plot. The lair is horribly overcrowded because monsters of all tribes and gangs are gathered to take counsel with the red dragon. Monsters are sleeping in the hallways because there is so little room, and the antagonism between races is at flash point. The PCs may be able to fan these resentments into intermonster battles. League of the Red Serpent is the third dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

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.
