This deluxe adventure takes heroes into the ruins of Gardmore Abbey, a monastery that was once the base of a militant order of paladins devoted to Bahamut. According to legend, the paladins brought a dark artifact back from a far crusade and stored it in their abbey for safekeeping, and evil forces gathered to assault the abbey and take it back. What the legends don’t tell is that this artifact was actually the Deck of Many Things, a force of pure Chaos. This adventure brings characters into the extensive dungeons beneath the ruins - dungeons that are warped and twisted with the raw forces of Chaos surrounding the cards of the deck.

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

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 slave markets of Katapesh may be an unsavory sort of business, but the trade metropolis’s enigmatic law enforcers have few qualms with the legal act of selling and buying flesh. Other factions, including the abolitionist Eagle Knights of Andoran, have their own opinions on the matter, however, and frequently send undercover agents into dangerous territory to break up slave rings. When one such Eagle Knight goes missing while investigating an underground slave operation beneath the dilapidated Twilight Gate district, it’s up to the PCs to delve an abandoned (but hardly uninhabited) qanat beneath Katapesh and discover her dire fate. Yet not everything is as it seems in the dank slave caverns under Twilight Gate, and clues hint that the slavers may have even more loathsome connections than initially suspected.

Odyssey of the Dragonlords is heavily inspired by stories from ancient Greek mythology. As we designed the campaign, we sought to include ideas from many different sources: The Odyssey, The Iliad, Jason and the Argonauts, The Oresteia, and others. However, Thylea is not ancient Greece. You will not find Zeus, Athena, or Apollo among the gods. As you explore Thylea, you will encounter familiar tropes, monsters, and treasures from Greek mythology—but the rules are different here. Mortals have only recently come to these lands. The world of Thylea blends high fantasy with the trappings of ancient history. Elves, dwarves, and halflings now live alongside minotaurs, centaurs, and satyrs. Our goal is to make your party feel like heroes from one of the greatest stories ever told—but the ultimate end of that story is entirely within your power. Your players will make choices that forever change the world of Thylea. As the gamemaster, we encourage you to embrace this idea and run with it. How will your players reshape history—and what does it mean to be a hero?
