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.

The giants are only a half-mile away - straight up. Giants and humanoids that sail down from the heavens? Where could they be coming from? No base town or general area map has been provided, as this adventure can take place anywhere and can be easily integrated into any existing campaign.The DM should make sure that the town in which the PCs start is large enough to provide most anticipated supplies, spells, and services. This module is not a simple hack·and slay expedition. It also involves diplomacy and wit; if the PCs attack everything in sight, they may be destroyed. But the adventure is not entirely negotiation, for it has a good share of hearty dungeon exploration as well. Pgs. 4-23

The last of his line, Baron Paytro NeMoren has left his dark secret sealed for decades in the family's underground vault. Now, years after his death, a group of stalwart heroes has gathered according to the baron's final wishes. At last, the seal will be broken and the secrets of the vault revealed. Can all sins be forgiven? The adventure is designed to kick-off a campaign, as it provides for an interesting way to get the party together. Instead of meeting at a tavern or being recruited by the local militia, each party member starts with a key to the NeMoren's vault, a key that was handed down by a friend or given as a gift for some good deed peformed in the past. The executor of the estate has gathered together all of the key-holders so that they could claim the contents of the vault. The vault can only be opened with all of the keys in unison. The vault is protected by a number of minor traps and tricks, but it also became the final resting place for the Baron's ex-lover, Lisette, and her brothers--all three of whom had attempted to blackmail the Baron. They were buried alive and are now undead. To complicate matters, a young umber hulk made its way to the vault, leaving some crude tunnels that were later exploited by hobgoblins coming from another surface entrance. The party will need to deal with the hobgoblins, the undead, the traps, and possibly the young umber hulk. There is a side-plot of poisoned groundwater in the nearby town that the party can also resolve by clearing out the undead and properly disposing of the putrid corpses leaking into the groundwater from the vault.

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
