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!

*THIS IS A D&D NEXT/5E PLAYTEST ADVENTURE* Imani, a Turmishan wizard and former adventurer, seeks the aid of heroes to infiltrate Dretchroyaster’s lair and recover the Diamond Staff of Chomylla—the key to powerful magic and wisdom locked away for thousands of years. In addition to his own sagely interest in the lore of lost Uvaeren, Imani recognizes the dangers of such powerful magic falling into evil hands. The dracolich has secured the staff in his lair’s cen- tral chamber, using ancient wards of protection that can be bypassed only by four artifact-idols once belong- ing to a cult of Bhaal. Each group of adventurers enters the dungeon through a different section of the dun- geon—a forgotten temple of Bhaal, a vast underground lake, a troglodyte village, or Dretchroyaster’s vaults. Dretchroyaster’s lair is no simple set of caverns and ancient ruins. It sits atop a source of great power and energy, which the dracolich and his Cult of the Dragon allies hope to use to unlock the secrets of the staff. Only by undertaking a unified assault against Dretchroyas- ter’s lair can the adventurers hope to recover the Diamond Staff and survive the dracolich’s fury. The adventurers must make their way through the lair and recover the Bhaalite idols that will help unlock the Diamond Staff, all the while dealing with the lair’s creatures and avoiding the dracolich as he pur- sues intruders. Entering the Chamber of the Diamond Staff, the heroes must overcome its magical wards and claim the staff before being slain by the dracolich and his servants.

"More than five hundred years ago, clans of dwarves and gnomes made an agreement known as the Phandelver’s Pact, by which they would share a rich mine in a wondrous cavern known as Wave Echo Cave. In addition to its mineral wealth, the mine contained great magical power. Human spellcasters allied themselves with the dwarves and gnomes to channel and bind that energy into a great forge (called the Forge of Spells), where magic items could be crafted. Times were good, and the nearby human town of Phandalin (pronounced fan-duh-lin) prospered as well. But then disaster struck when orcs swept through the North and laid waste to all in their path. A powerful force of orcs reinforced by evil mercenary wizards attacked wave echo cave to seize its riches and magic treasures. Human wizards fought alongside their dwarf and gnome allies to defend the Forge of Spells, and the ensuing spell battle destroyed much of the cavern. Few survived the cave-ins and tremors, and the location of Wave Echo Cave was lost. For centuries, rumours of buried riches have attracted treasure seekers and opportunists to the area around Phandalin, but no one has ever succeeded in locating the lost mine. In recent years, people have resettled the area. Phandalin is now a rough-and-tumble frontier town. More important, the Rockseeker brothers - a trio of dwarves - have discovered the entrance to Wave Echo Cave, and they intend to reopen the mines. Unfortunately for the Rockseekers, they are not the only ones interested in Wave Echo Cave. A mysterious villain known as the Black Spider controls a network of bandit gangs and goblin tribes in the area, and his agents have followed the Rockseekers to their prize. Now the Black Spider wants Wave Echo Cave for himself, and he is taking steps to make sure no one else knows where it is." Extra Info from AL.com users: by @marcellarius. "There are a variety of locations in this adventure: the town of Phandalin, a gang hideout, a ruined keep in the forest, a destroyed village, and Wave Echo Cave (a dungeon crawl). The adventure is written in a sandbox style and relies on the players to choose their path. Phandalin offers several side-quests which could serve as hooks for continuing adventures. The premade characters have ties in their backgrounds to NPCs and locations. If you're not using these you'll need to consider other ways to introduce key NPCs."

Deep in the elven forests of Myereth, ancient rowan trees spread white boughs above a sacred site. Pillars of stone twist like some strange form of vine, curling among the branches and reflecting the light of a silvery moon. The forest is silent, and beautiful, protected since the dawn of time by a powerful Unicorn. The elven forest of Myereth is well known throughout the world as a safe haven of good and peace, a place where evil cannot stand to enter and where the trees weep healing tears upon those injured within its boundaries. Any player character elves know of the forest, its healing properties, and its legendary beauty. They may have heard of it as a legend, or they may have visited its mystic shrine when they were children, brought along on a pilgrimage by other elves. But something has gone terribly wrong. Refugees from Myereth, terrified and confused, are flooding into other elven cities. They speak of a great evil that has conquered the forest, one that has killed the body of the immortal Unicorn and tainted its spirit. Myereth runs with blood, they say, and the once-powerful rowan trees have begun to wither and die. In the center of the Rowan Grove, the bloodied bodies of the last elven warriors of Myereth lie scattered and broken. Those responsible call themselves the Servants of the Blood Moon, and they are led by a dark-robed sorcerer. The surviving elves do not know this evil man — all but one of those who fought against the Servants died — but they know that the sorcerer calls himself Tamarat. He has butchered the Unicorn, the spirit of the forest. The Myereth, and the elves, are dying.
