Long ago, before the arrival of civilized humanoids, a large colony of ogres thrived in the local area. When a great invasion from another dimension threatened this colony, their king, Koptila, prayed for his people to be spared. The gods heard these pleas, but commanded Koptila to sacrifice himself. The leader did so, and the clan disappeared—whisked away by the gods and lost to time. Over the years, a city grew up above the former subterranean home of the ogres, and no aspect of Koptila’s ancient bargain was preserved or remembered. Even so, the stars are aligned for the return of Koptila and his people. These powerful repatriates are unlikely to appreciate the changes in their old home. A sage has found dusty documents prophesying this return, and he asks the PCs to investigate the catacombs to defeat the potential threat to the city. The PCs travel down through city sewers and subterranean passages before finding the catacombs that the ogre colony once called home. Pgs. 48-53

Important: The adventure is 1e but it has monster conversion notes for D&D 4th edition The town of Highport, once a human community overlooking Wooly Bay from its perch on the northern coast of the Pomarj, fell prey to hordes of humanoids swarming out of the jungle-covered hills surrounding the settlement. Though the orcs, goblins, kobolds, ogres, and gnolls razed much of the place in their ferocious rampages, the smoldering ruins they left behind soon became a new kind of community, a place of trade between the humanoid “locals” and the unsavory human traders who have no compunction about doing business with them. Slaves are a commodity in ready supply in Highport’s market, since many pirates raid up and down the coast of the bay, putting fishing villages to the torch and filling their holds with captured refugees. Slavery has become a thriving business in the town, and rumors abound of a cartel of Slave Lords who run things from behind the scenes, filling their coffers in secret from the buying and selling of human chattel. The trade has become so prolific that the good folk to the north have grown tired of these depredations and decided to fight back. Forces of righteousness and honor have recently descended upon Highport, some openly and others in secret, in various attempts to destroy the machinations of the Slave Lords and abolish the abominable enterprise that has taken far too many loved ones from home and hearth. One such doughty servant of goodness is Mikaro Valasteen, a cleric of Trithereon. Mikaro slipped unnoticed past the crumbling walls of Highport with a single mission: to rescue and transport as many slaves to their freedom as possible. Mikaro and a handful of faithful assistants located a number of escaped slaves—as well as rescued a few more not sufficiently restrained and guarded—and shepherded them through the gates and beyond the reach of their humanoid tormentors, returning them to their lands and homes. This covert freedom brigade enjoyed remarkable success early on, since the servants of the Slave Lords were often lax in their vigilance and sloppy in their efforts to prevent loss of the “merchandise.” After one too many shipments never made its destination, the humanoids stepped up their security and the normal channels of escape from Highport closed to Mikaro and his team. He cannot risk exposure by smuggling the freed slaves through the gates as merchandise any longer, since shipments of goods are now regularly stopped and checked. No longer able to free the slaves in that manner, Mikaro began hiding his charges in an abandoned villa in a particularly rundown part of the town. Although they are safe for the moment, their numbers have grown unmanageable, and the priest fears it is only a matter of time before someone slips up and brings slavers to their doorstep. Ever more desperate to find a new means of escape from Highport, Mikaro has started work on a plan that is both daring and dangerous. He intends to use a series of old sewers coupled with natural caverns running beneath the town as an escape route to the sea beyond the walls. But he needs someone to clear out the creatures and pitfalls he knows lie within. Pgs. 2-27

As iron is eaten away by rust, so the envious are consumed by their own passion. — Antisthenes The destruction of Cyre and creation of the Mournland marked the end of The Last War. Since then, a towering wall of mystic fog has covered what used to be the nation of Cyre. Those who have ventured inside and made it out have spoken of unusual beasts, wild warforged, and other strange occurences. Most stay away. Others dedicate their lives to plundering the mysteries beyond the veil. House Cannith is the House of Making and, despite being split over the destruction of their homeland, they are still very adamant about keeping their monopoly over arcane creations and are very suspicious of anything coming out of the Mournland. Recently, rumours reached the heads of the Cannith South enclave that some scavengers working for the Daask organisation actually captured living spells from inside the Mournland and brought them back to Sharn for study, taming, and who knows what else. Now Cannith employs independent contractors to enter the secret lab, and destroy the research and its future. Another group will hunt down the actual scavengers and eliminate the spells themselves. This adventure takes place in Sharn, the City of Towers, some time before the formation of the independent adventurers organisation by 'The Twelve'. It is an infiltration mission in hostile territory which includes some investigation, maybe a bit of socialising, and some quick dungeon-crawl elements. It is designed for multiple possible endings. In my mind, this adventure is E for Everyone and doesn't contain anything dark, NSFW, or triggering beyond any other standard D&D adventure.

The road to the remote village of Swordfall is a long and winding one. It takes pilgrims who wish to visit the holy site from the main trade road, through the hills, and into the mountains where once, thousands of years ago, two gods engaged in an epic battle. Now, all that remains of the battlefield is a lone sword, several hundred feet tall, embedded in the ground at the center of a massive crater. Over the years, a large temple to Thuul, god of battle, sprung up around the site. Now, warriors and fighters from across the land travel to Swordfall to pay their respects once in their lifetime. Recently, however, pilgrims have begun going missing. Somewhere between the main road and Swordfall itself, something, or someone, has been waylaying travelers. Unbeknownst to most, a cult to Ghenna has taken over one of the lone inns along the route and has begun using it to capture and sacrifice pilgrims to their own dark god. Unless a group of adventurers can stop them, the sacrifices won't stop.

They travel through the wilds of Vesperin in search of the missing person, finding trouble and helping locals along the way.

The players will need to investigate the situation and choose sides in a longstanding feud between the mayor and a local magic user. Chapter 3 - After clearing a tribe of violent orcs from a nearby mountain pass to protect the residents of a town, the party will have to enter the lair of a long-dead dragon to rescue their quarry from a band of goblinoid slavers, where they discover an entrance into a dwarven city, lost and forgotten centuries ago. Chapter 4 - The party will have to traverse the ruins of the dwarven city, avoiding hazards and battling the horrors that lurk there, to uncover the identity of the slaver's leader. A discovery that will lead them through a treacherous forest to the city of Tsurlagol in search of a pirate ship called the Star Carver, and its drow captain, The Viper's Kiss. Along the way, they meet an unlikely ally. Chapter 5 - Once they arrive in Tsurlagol, the players will have to choose between gaining the assistance of the city council to fight the pirates head on, or making a deal with the Viper's Kiss, herself.

It is designed for character level 1-5, and uses material from the Dungeon Master's Guide, Monster Manual, and Volo's Guide.

Sewers of the Underguild is an adventure designed for characters of at least 11th level, and characters up to 15th level will find plenty of challenges. Hidden within these narrow passages and filth-filled channels is a guild of vampiric rogues, led by their master Sangre and his aide, a nycaloth called Ankoz. Deadly traps abound, so a skillful rogue will be a lifesaver. Because of the high likelihood of desperate combat with numerous vampiric and monstrous opponents, it is suggested that a cleric and at least two fighters be prepared to beat back the many watchdog monsters the guild employs. You can hide the locales in Sewers of the Underguild in any ruin or location that fits your campaign purposes. A thriving metropolis that just happens to have a large crime and vampire problem would fit the bill nicely. In the Lost Lands campaign setting of Frog God Games, the Underguild is located in the sewers beneath the ruins of Curgantium, the ancient imperial capital of lost Hyperboria. Located at the edge of the modern Kingdom of Foere, the Underguild still finds itself located centrally enough to pull the strings of its weblike network running throughout the former lands of the Hyperborian Empire.
