In the Yatil Mountains south of Perrenland there is rumored to be a magical hoard of unsurpassed value, a treasure of such fame that scores of adventurers have perished in search of it. Find the perilous Lost Caverns of Tsojanth and you may gain the hidden wealth of the long-dead arch-mage-- if you live. Module S4, this contains a brief wilderness journey to the caverns, but the bulk is underground. The caverns are noted as a previous lair of the Arch-mage Iggwilv- though she is long gone, her Demonomicon remains. This module marks the first appearance of several monsters and items that would later appear in the Monster Manual 2 and Unearthed Arcana. A labyrinth features in the caves. TSR 9061

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?

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.

For over a thousand years the things that lurk beneath the waters, skulk in the darkness and lie hungrily in dank crypts have been patient, while all around them men and monsters bicker amongst themselves, bold enough to traverse the dark caverns' depths but afraid or perhaps wise enough to leave the forgotten vaults and hidden passages alone. Beneath the lost ruins of ancient Thracia lie the vast caverns of a once great civilization. While a death cult rules the surface, the Minotaur King and his beast men lurk fall below. Descend even deeper into the darkness and discover a lost and arcane world that waits for those brave enough to enter!

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.

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
