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!

The town of Somber Hill is a quiet settlement in the foothills of a mountain range. A few days travel from the nearest city, the people of Somber Hill are a humble and self-reliant bunch. Unbeknownst to its people, the small town hides a sinister secret, some of the residents of Somber Hill belong to a cult that worships a long dead entity. 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.
