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!

Not even memories of past glory live on in the gentle hills around the village of Kusnir. Today its people have more concern for commonplace things, like the harvest, trade, and the threat of death in the night! Kusnir is beset by a skulk. The attentions of such a creature are a curse on any community. Streets and alleys which ring to the voices of children by day become fearful, shadowy places by night. Men go abroad armed and in groups, while women and children stay behind locked doors and even there are not safe. But life goes on. The lot of the peasant is always hard, what cannot be prevented must be endured and, of course, things could be worse. Much worse. The skulk has begun to visit the village more and more often. Sometimes it kills, yet just as often it spares a victim, leaving clear signs of what it might have done had it wished. Its visits are now marked by strange and illegible symbols scrawled in blood on the walls of the buildings. The people are worried, helpless, and desperate. Desperate enough to welcome adventurers. UK2: "The Sentinel" (1983) is the second UK-series adventure, the fifth TSR UK adventure overall, the first solo effort by Morris, and the first half of the two-part Adlerweg series (whew!). It was run as a tournament at the GamesFair '83 Open, then published later in 1983. TSR 9101

Lo! The corpse of poor, departed Scholar Zubayr, washed up on the shores of the River of Sand, lies in the charnel house…destined to become dinner for a cult of cannibals.

Still unmoved to action? Know then, adventurer, that the Scholar was hot on the trail of lost treasure! If you can claim his body from the cult and decipher the clues he left behind, long-buried riches and powerful magic might be yours. But nothing is simple in this city of dark wonders: others converge on the charnel house in pursuit of wealth, vengeance, or both. Can you out-fight and outwit vile cultists, undead catfolk, a cunning werecrocodile gnoll, and the deadly secrets that lie buried beneath the River of Sand? Set in the city of Per-Bastet in the Southlands Campaign Setting, it is meant for play either as the thrilling sequel to Cat and Mouse, or as a standalone treasure hunt!

One crazy night in Waterdeep. Start as tavern bouncers. End up on the Astral Plane. All in one crazy night in Waterdeep.

And what better motivation than 200gp per person for a single night of work. Sound too good to be true? Well, here's the catch: all damages to the tavern are to be deducted from that amount. And there is no shortage of festival-goers looking to unwind by wrecking other people's stuff. Over the course of the festival, the party must deal with drunken wizards, vain bards, loud goliaths, incompetent parade goers, complaining neighbours, disruptive satyrs, aspiring cultists, and a full-on tavern brawl. As well as an unusual number of strange slugs crawling around. Slowly they become aware there is something off about the Slumbering Prince. And when a reckless noble disturbs the secrets beneath the tavern, our heroes must soon delve into the hidden dungeon themselves. Down below, they discover the terrible threat: a planar rift that can only be opened on Midsummer's Eve, and the slumbering demigod that awaits beyond, the great astral slug Cthumbra!

In part one of the Randal Morn Trilogy, "The Sword of the Dales," the legendary leader of Daggerdale, Randal Morn, was captured by unknown assailants as he sought to regain the great weapon for which that adventure was named. A stalwart band of enthusiastic heroes was recruited to ride to his aid, yet all they recovered was the Sword itself and a message: "Seek me in Spiderhaunt Wood." In the second part of the trilogy, "The Secret of Spiderhaunt," those same adventurers found Randal and freed him briefly, yet he was almost as quickly torn from their grasp by an agent of the evil Zhentarim, seeking to end the threat of Randal Morn's return to power. In this final episode, the heroes must follow the kidnapper's trail and rescue Randal Morn again before the Zhentarim finish interrogating him and the axe falls upon his neck. Armed with the Sword of the Dales and aided by a powerful spirit that lives within the weapon, the heroes must march into the heart of Zhent-occupied Dagger Falls, free Randal Morn, and save the city from utter destruction. The job is dangerous - perhaps more than the heroes can handle - yet those who would live in songs and legends cannot concern themselves with living to a ripe old age! This is the final part of a trilogy of modules that began with "The Sword of the Dales" and "The Secret of Spiderhaunt." TSR 9488
