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!

HSING bears foul news: SEER has been captured.

Laugher’s Gorge occupies a stretch of the canyon that runs through the local badlands, named for the haunting laughter that occasionally erupts from its depths. When travelers using the road past the gorge become infected with cackle fever, it’s up to the party to find out what’s causing the mysterious laughing sickness. Though they find a pack of gnolls infesting the canyon, it’s no joke when they discover who (or what) is pulling the strings! Laughter and humor are central themes in No Laughing Matter. The players are met with the will of a prankster god, riddles to solve, and may be forced to come up with some jokes of their own. But this isn’t an adventure to take lightly. If the party underestimates Laugher’s Gorge, they may find themselves infected with cackle fever… and there’s nothing funny about that!

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.

Known only as The Dark One by their followers, this ancient being once called Old Somber Hill home. Their dark master is entombed in the catacombs beneath the town, and the cult hopes to resurrect their master with a blood sacrifice. The Crypt of Somber Hill is a Setting Neutral adventure and thus can be easily included in any existing story-line with minor alterations and adjustments or outright slotted into any existing campaign setting.
