In the city of Waterdeep rests a tavern called the Yawning Portal, named after the gaping pit in its common room. At the bottom of this crumbling shaft is a labyrinthine dungeon shunned by all but the most daring adventurers. Known as Undermountain, this dungeon is the domain of the mad wizard Halaster Blackcloak. Long has the Mad Mage dwelt in these forlorn depths, seeding his lair with monsters, traps, and mysteries—to what end is a constant source of speculation and concern. This adventure picks up where Waterdeep: Dragon Heist leaves off, taking characters of 5th level or higher all the way to 20th level should they explore the entirety of Halaster’s home. Twenty-three levels of Undermountain are detailed herein, along with the subterranean refuge of Skullport. Treasures and secrets abound, but tread with care!

'Help wanted: Fearless crew to stop undead pirates. Pay bills before applying." The first thing you'll hear is dead silence. The party must hunt down a ghostship disrupting commerce in the trade port of Koll. At least, everyone thinks it's a ghostship, the party may discover otherwise.

The ship makes its way into the Corsair Mists, a region of the Halo Ocean said to devour ships and drive sailors mad. Somewhere in the oppressive fog, the White Ship awaits, but before the Adventurers can make it to their final desination, they must overcome the challenges of the mist. The fell necromancer Molo of the Thirteen Wives is still out there, still seeking to find his key to immortality and power that could jeopardize the entire Nameless Realms, and only the fearless crew can stop him. Join a sea elven ritual to hunt megalodon sharks, explore a long-cursed alchemist's tower made of blue crystal, and journey to the forge of Hyperion, Titan of Fire, himself. This adventure is formatted to both 1E & 5E gaming rules. Also available in PDF.

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?

As the characters investigate the origin of the drug, they uncover an international criminal conspiracy, wild and ancient magic, and a threat to reality itself. Contents: This beautifully made, 54-page adventure offers: A fully fleshed out, setting-agnostic starter area, brimming with colourful NPCs and hooks for adventure. Balanced encounters to bring characters to level 2; then some more devious encounters on their way to level 3. Three mini-dungeons built on the design philosophy of the "5 room dungeon method" Multiple big, cinematic set-piece boss encounters what will make your players feel epic. A facetted intrigue, which does not immediately suggest a simple, ready-made solution but invites the players to come up with their own, personal approach. Why pick this adventure? Hey, my name is Marius. This is my first time publishing on the DMs Guild but I wouldn't call myself a newcomer. I started playing Pathfinder 1e back in 2014. When I took over as our group's DM in 2019, we swapped over to 5e. We have run many, many modules and adventures since. Currently I play three games a week. In short: You could say I'm hooked. I created The Goblin Bathwater Incident as the ideal adventure for in-between your big modules, but it isn't a simple little adventure. With a playtime of about 30 hours, it still manages to hit that sweet-spot, where it establishes context, makes you grow fond of NPCs, and makes those big bossfight wins so much sweeter, all without taking more than a few sessions. The Goblin Bathwater Incident is different from many of the 1st tier adventures in that it pits the characters against traps and monsters, but also asks difficult, open-ended ethical questions, where a simple strategy of "apply sword to head of bad guy" will not cut it.

Centuries ago, the despotic Alphaks, ruler of Alphatia, was banished to another world. From his own sphere of entropy he learned to manipulate men, and now seeks revenge against the human race. The volatile region of Norworld, a perennial battleground between Thyatis and Alphaita, draws Alphaks's attention. The already existing frictions, small-time political players, and petty vengeances are the sparks Alphaks will use to ignite a huge war that will destroy man-kind. This is an adventure of politics and diplomacy, of treachery and treason. Only courageous and bold actions can save Norworld from the horrors of war and liberate its people from oppression. The Vengeance of Alphaks may be played as a sequel to module M1, Into the Maelstrom, or separately. The D&D Master Set Rules are necessary for running this game. TSR 9148

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.
