The ancient world of Harth withers beneath its dying sun…but it’s not dead yet. Welcome to the strange and dangerous city of Carcassay, huddled below the skeleton of a titan rat, sprawling above the ruins of countless dead civilizations. This is where folk come to find wealth, power, revenge, secrets, oblivion… and everything in between. Carcassay is a sandbox city adventure. There are many locations to explore in, around, and under the city. Players can explore any place at any time, and may radically reshape the city’s politics, economy, religions, and physical existence. There are standard dungeons stacked under the city, and GMs are encouraged to keep adding more dungeons… all the way down. Tone. It leans more toward low fantasy or sword-and-sorcery. Most shops look like real shops. Most people look like real people. But strange and horrible things lurk everywhere as soon as you start to scratch the surface. This is my Lankhmar. Carcassay is a vast, bizarre city. It has over 100 locations where you can meet Chaos cultists, Lawful knights, retired adventurers, shopkeepers, brewers, musicians, artists, scientists, hermits, royalty, beggars, doctors, space vampires, eldritch horrors, machine priests, crab colonists, mushroom farmers, mummies, assassins, and diplomats from distant lands… and the moon. And every one of them has goods or services to sell, and a quest (or three) to offer. What sort of quests? Fetch a relic, assassinate a rival, find a relative, steal a soul, implant an agent, cure a disease, stop a riot, solve a murder that hasn’t happened yet, hunt a thief, locate a shrine… the list goes on. And for every Quest, there is a specific Reward: money, weapons, relics, Chaos mutations, exclusive memberships, information, Angelic miracles… the list goes on. This is a place where you can make a lot of money, but also where you can spend that money on interesting goods and services. Factions? We have a few. Seven Chaos cults, five knightly orders, two mercenary companies, four wealthy families, six (seven!) Corpse Lords, foreign diplomats, rival innkeepers, rival tavern owners, plus all the dungeon-delving gangs currently mucking about underground. When you grow weary of all the adventures at ground level, there are three classic dungeons buried under the city to explore. This book contains months (if not years) of campaigning. Enjoy the Chaos.

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.

Can the Pathfinder Society halt the beast’s plan in time, or will he build his army of revenge and sow chaos in Absalom?

The Thieves Guild Ebonclad has welcomed its newest team to the fold, assigned to the Keeper Reese Kincaid for instruction. The recruits are green, but capable. Their Keeper has devised a job for them to assess their talents. If his new team is successful, he gets some insight as to how his new Scraps operate, in addition to scratching something off his to-do list. If they die trying, well, then Reese has one fewer thing to worry about. The party must track down the slum thief Dale E’ssio, and reclaim valuables marked for the guild. Should anything unfortunate happen to Dale, there must be no evidence tracing things back to Ebonclad. The mission will require the party to enter Kintalla’s sewers to ultimately confront Dale E’ssio in a ruined slum house. Characters may have to explore the city while trying to get a lead on him.

The search for a missing girl leads PCs to uncover the re-emergence of a dangerous cult of Serpentfolk. This is a low-combat adventure, mostly requiring roleplay and investigation. NOTE: The Tales of Freeport that contains this adventure is NOT one of the versions currently available in the Green Ronin store. Those contain short stories. This is an older item that appears to no longer be available from Green Ronin. It is possible that the adventures within it have been included in other products since then. But I have linked to the original product on DriveThru RPG.
