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

A goblin warband has found the secret tunnel which leads from the dwarven keep of Hearth-Home to the nearby hills. The tunnel is intended to be a means of escape if the keep ever falls to attackers, but now it has provided goblins with an easy way into the Underkeep. So far, the goblins have confined their attentions to the various underground rooms that make up the Underkeep, but sooner or later they will find a way to the surface. They pose a serious threat to Hearth-Home - the goblins must be cleared out of the Underkeep so this breach in security can be repaired before the orcs hear of it and overrun the dwarven keep. This adventure is slightly more challenging than Red Hand Trail, and it is recommended that it is played after that quest and before Palace of Dread. However, the scenario in Trouble Below can easily be played independently from the rest. Part of TSR 1076 The Goblin's Lair

The ground-breaking introductory adventure for Dungeons & Dragons that served as a DM aid in the first D&D Basic Set, released by TSR in 1977. This set included a 48-page rulebook covering the first three levels of play, and was skillfully edited by Dr. J. Eric Holmes from the original 1974 D&D rules written by Gary Gygax and Dave Arneson. The original set included an exemplary dungeon level, but it was a loose collection of examples and not geared toward starting characters. Holmes advanced this concept by writing a new thematic dungeon with a strong backstory, creating an adventure that has remained a fan favorite over the decades. Officially, its only title is "Sample Dungeon" but colloquially it goes by various names based on Zenopus, the doomed wizard who built the dungeon under his tower

The invisible enemy. Rats, cats, and double-drats. Six months ago, the residents of Luskwald heard rumors from passing merchants of a possible goblin incursion into the region. News from the nearest city confirmed speculations that goblin tribes were massing in the distant hills. Worried about the future of his small community, the Laird of Luskwald commissioned a stonemason and several carpenters to rebuild a damaged keep two miles north of the village. The repair crew worked for weeks restoring the keep's fallen walls, while waiting nervously for the first goblin to show its ugly head. For the first several days the restoration proceeded according to schedule, but in the weeks that followed several 'accidents' led many to believe the keep was cursed or haunted. In the past week three of Luskwald's villagers have died, each the victim of a grisly assassin whose identity remains a mystery. Several citizens have heard or seen peculiar things over the last several days, leading them to believe that Luskwald has been cursed, or worse, ravaged by angry spirits--perhaps sent by a greater evil that dwells within the ruined keep!
