As growing numbers of lastfolk begin to question the traditions of the Last Kingdom, forces far more sinister, preying on the curiosities of mortals, have begun to emerge into the light... Can the PCs discover and end a treacherous plot that threatens to destroy the relative peace of the Last Kingdom?

The ground-breaking introductory adventure for Dungeons & Dragons that served as a DM aid in the first D&D Basic Set, released by TSR in 1977. This set included a 48-page rulebook covering the first three levels of play, and was skillfully edited by Dr. J. Eric Holmes from the original 1974 D&D rules written by Gary Gygax and Dave Arneson. The original set included an exemplary dungeon level, but it was a loose collection of examples and not geared toward starting characters. Holmes advanced this concept by writing a new thematic dungeon with a strong backstory, creating an adventure that has remained a fan favorite over the decades. Officially, its only title is "Sample Dungeon" but colloquially it goes by various names based on Zenopus, the doomed wizard who built the dungeon under his tower

Freeport is a fantasy “free city” you can place in a fantastic setting. Its basic premise is a pirate city gone legit… at least on the surface. In truth, the pirate tradition is alive and well in Freeport, but camouflaged by a veneer of respectability. These days the city’s pirates are privateers, legalized pirates Freeport loans out to the highest bidder. You’ll learn more in the short history of the city that follows. This should help give you a taste of the flavor of Freeport before the adventure begins and the given background is all you need to run this adventure. It is an ideal starting place for a new campaign as the player characters find themselves stranded in Freeport after a deal goes sour. A seemingly simple job plunges them into the strange underside of the city, where they uncover secrets worth dying for. Death in Freeport is the first from the Freeport trilogy, together with Terror in Freeport and Madness in Freeport. Synopsis: Death in Freeport drops the player characters into the midst of political and magical intrigue, as the hidden Brotherhood of the Yellow Sign manipulates events to bring its dread god to the world. Freeport is still a bustling center of trade, but evil currents run beneath the surface. There are secrets here, and questions unanswered. The characters will undoubtedly learn there is more here than they expect in a simple seaport. The question is, will that knowledge kill them? As the adventure begins, the player characters (PCs) have just come to Freeport on a merchant ship. While on the docks, the PCs are attacked by a press gang, who mistake them for easy marks. The press gang is handily beaten off; since they are unused to real resistance. A bookish young man named Brother Egil then approaches the PCs. He says that he’s been looking for a group that can take of itself, and that he has a job for them if they are interested: finding a missing librarian. The missing man, Lucius, disappeared two days previously, and Egil is eager to find him. Egil gives the PCs some background on Lucius and his strange behavior. The PCs are then free to investigate: They are likely to visit Lucius’s home, the temple to the God of Knowledge, and an orc pirate ship. This should form a picture of Lucius as a man searching for his own past—who found something he wasn’t counting on. Following a trail of clues, the PCs learn about the Brotherhood of the Yellow Sign. With a little luck, the PCs can trail the cultists back to their hideout, penetrate the lair, and discover secret tunnels underneath it. Deep underground they find degenerate serpent people, and eventually Lucius himself. The librarian has been tortured badly and will die without aid. The PCs also have to deal with the leader of the cult, a man they may recognize from the temple. When the cult priest is slain, they are in for an even bigger surprise. He was not human at all, but a serpent man in disguise. What this means for Freeport only the gods can say.
