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 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 country of Rhyl has been beset nearly every night for many years by a large, terrible creature that flies out from the mountains near the city of Asereht. Nearly a year ago the creature broke through the wall of King Namreh’s castle and carried off the king’s son, Prince Laechim, along with a large amount of the royal treasure. After the creature’s raid on the castle, King Namreh ordered his army to search the mountains and discover Astylis’ complex. The soldiers made two forays into the mountain wilderness, but each time were harassed and eventually driven back by goblin raiders.

For reasons which the king has never found out, none of these rescue parties has ever returned to Asereht. Your party is now attempting to be the first. Pgs. 37-44

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?

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.

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.
