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.

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!

Suddenly, the grasses part, and Lion Castle rises majestically before you! "Magical riches await those who enter!" "Beware of man-beasts!" Voices flood your head again. Will you brave the haunted castle? Can you afford not to? It's all up to you in this D&D Solo Adventure.

Anandak, a red dragon, has taken over an abandoned dwarven stronghold as his lair. He has also assembled together a rough confederation of monsters to act as his bodyguard. Anandak is preparing to enter into an alliance with the Black Prince, the March Lord Draven. The plan is for Anandak's monster allies to terrorize the lands north and east of Knacker Knob while the Black Prince, on pretext of marching to the aid of Knacker Knob, take control of Knacker Knob and the surrounding region. An emissary from the Black Prince, Lord Gonzaga, is currently in the dungeon, and he is in possession of papers that might reveal the Black Prince's treasonous plot. The lair is horribly overcrowded because monsters of all tribes and gangs are gathered to take counsel with the red dragon. Monsters are sleeping in the hallways because there is so little room, and the antagonism between races is at flash point. The PCs may be able to fan these resentments into intermonster battles. League of the Red Serpent is the third dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

Giants have been raiding the lands of men in large bands, with giants of different sorts in these marauding groups. Death and destruction have been laid heavily upon every place these monsters have visited. This has caused great anger in high places, for life and property loss means failure of the vows of noble rulers to protect the life and goods of each and every subject -- and possible lean times for the rulers as well as the ruled. Therefore, a party of the bravest and most powerful adventurers has been assembled and given the charge to punish the miscreant giants. This module contains background information, referee's notes, two level maps, and exploration matrix keys. It provides a complete module for play of ADVANCED DUNGEONS & DRAGONS, and it can be used alone or as the first of a three-part expedition adventure which also employs DUNGEON MODULE G2 (GLACIAL RIFT OF THE FROST GIANT JARL) and DUNGEON MODULE G3 (HALL OF THE FIRE GIANT KING).

Under the Temple Crypt is the first in a series of site-based, Swords & Wizardry** compatible, “micro modules” that can be dropped into just about any campaign (especially a sandbox-style campaign). No underlying story-hook or rationale for exploring the site is given here. This dungeon assumes that there is a temple somewhere with a mysterious walled-in doorframe in the basement crypt. The walled-in doorframe predates the temple itself and leads to ancient subterranean structures that hint of an older civilization as well as an expansive underworld.

Synopsis: Goblin Bathwater, a magical drug, has taken hold in a sleepy coastal town at the edge of the Empire. 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.

At just 8 pages, with lots of illustrations, this adventure is much shorter than most TSR-published modules of the era (mid-90s). It is a very simple D&D adventure. It features a macguffin quest that immediately pushes the players into a dungeon crawl through the five-and-a-half-page "Dungeon of the Mad Warlock". The idol of old, The Jade Hare, as been taken from the Dar el-Tamyya, stolen by Goblins, who strangely enough killed no one. Abdullah, the old man who cared for the statuette remembered that about a month ago a stranger has asked if he might purchase the Jade Hare. Though he offered much gold, Abdullah of course refused the offer. Whom Abdullah describes the other villagers recognize as Abu-Ghabar, the mad warlock who lives in the hills. He is rumored to have built a dungeon there. Who knows what strange purposes the mad warlock has for the Jade Hare? In any case, the precious statuette's theft is an intolerable strain on the honor of the village and all the tribe therein. A party must be assembled to confront the warlock. This party may consist of none other than yourselves. Won't you save Dar el-Tamyya's ancient honor, and thwart whatever sinister plans the warlock has? TSR 9259
