"The longest, and perhaps strongest, AD&D adventure we've ever done." The fabled Mace of St. Cuthbert has been lost from the sight of both human and demi-human for many centuries. Some claim it lies at the heart of an active volcano, guarded by salamanders and flowing lava; others swear it lies buried deep inside the earth, warded by powerful magics raised by those who would see its power denied to the forces of Law and Good. A few assert that it has never left the possession of the Saint, and even now he holds it in his strong right hand. But a few claim that none of these are so that long before the Sainted Cuthbert rose to his exalted station, his mace was hidden away from those who would steal it before he returned for it, hidden away outside the bounds of normal time and space, in a place so outlandish that the Mace's power and destiny would be unknown and unknowable, and thus safe.

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

The baron himself has been kind enough to provide you with that answer: streams of raw gold gush from a burning mountain somewhere in the Sea of Dread. All you have to do is find this mysterious mountain. Unfurl the sails! The open sea awaits you and your crew as you sail from the city harbor. But beware! The Sea of Dread has more than earned its title over the centuries. Can you survive the perils of the sea? Will your crew mutiny before you reach the Burning Mountain? Or will you have to throw crew-members overboard just to make room for the gold? Solo adventure. "Lathan's Gold" is a real innovation in solo adventure design, considerably more complex than any of the gamebooks then being produced. Though the adventures uses the typical trope of numbered paragraphs, its paragraphs are divided into six types: "S"pecularum, "U"rban", Island "E"xploration", "C"oastal", "T"rade Routes, and "V"oyages. Players can jump between the sections, then return, in slightly freeform ways. Players are also required to keep track of hit points, money, and treasure (which were typical for the more advanced gamebooks), and rations, days remaining, and hull points (which were not). Another freeform element, quite unusual for gamebooks, is the "wandering monsters" table, which introduces semi-random encounters. TSR 9082
