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 deluxe adventure takes heroes into the ruins of Gardmore Abbey, a monastery that was once the base of a militant order of paladins devoted to Bahamut. According to legend, the paladins brought a dark artifact back from a far crusade and stored it in their abbey for safekeeping, and evil forces gathered to assault the abbey and take it back. What the legends don’t tell is that this artifact was actually the Deck of Many Things, a force of pure Chaos. This adventure brings characters into the extensive dungeons beneath the ruins - dungeons that are warped and twisted with the raw forces of Chaos surrounding the cards of the deck.

For over a thousand years the things that lurk beneath the waters, skulk in the darkness and lie hungrily in dank crypts have been patient, while all around them men and monsters bicker amongst themselves, bold enough to traverse the dark caverns' depths but afraid or perhaps wise enough to leave the forgotten vaults and hidden passages alone. Beneath the lost ruins of ancient Thracia lie the vast caverns of a once great civilization. While a death cult rules the surface, the Minotaur King and his beast men lurk fall below. Descend even deeper into the darkness and discover a lost and arcane world that waits for those brave enough to enter! Necromancer Games and Judges Guild have teamed up to expand and update the classic module Coverns of Thracia for 3.5. Designed for characters of 3rd to 8th level and higher, the Caverns of Thracia is a mini-campaign setting that presents intricate plots and exciting adventures.

The country of Rhyl has been beset nearly every night for many years by a large, terrible creature that flies out from the mountains near the city of Asereht. Nearly a year ago the creature broke through the wall of King Namreh’s castle and carried off the king’s son, Prince Laechim, along with a large amount of the royal treasure. After the creature’s raid on the castle, King Namreh ordered his army to search the mountains and discover Astylis’ complex. The soldiers made two forays into the mountain wilderness, but each time were harassed and eventually driven back by goblin raiders. Since the failure of the second assault, the king has taken to commissioning small parties of mercenaries and adventurers, sending them into the mountains with promises of great reward upon the completion of the rescue mission. For reasons which the king has never found out, none of these rescue parties has ever returned to Asereht. Your party is now attempting to be the first. Pgs. 37-44

Gray Mountain lies deep in the lush elven forest. The temple there was a haven of meditation and learning - until taken over by an evil cleric known as the Rahib. Far under the mountain, he paces before the temple's great altar. A brown-robed servant rushes in and falls to his knees, trembling at the sight of the Rahib's black panther. "Rahib, adventurers came to the village as the sun rose - the strangers now protect Rahasia." A scowl crosses the Rahib's face. "I must have Rahasia! Attack again tonight." As the servant scurries away, a deep growl rises from the giant cat. Gripping the panther's leash, the Rahib paces again, speaking out loud. "We must dispose of these strangers quickly; the secret beneath the temple will not wait much longer." Note: the setting is unspecified, but certain tie-ins, like the wines, prefigure Ravenloft.

The giants are only a half-mile away - straight up. Giants and humanoids that sail down from the heavens? Where could they be coming from? No base town or general area map has been provided, as this adventure can take place anywhere and can be easily integrated into any existing campaign.The DM should make sure that the town in which the PCs start is large enough to provide most anticipated supplies, spells, and services. This module is not a simple hack·and slay expedition. It also involves diplomacy and wit; if the PCs attack everything in sight, they may be destroyed. But the adventure is not entirely negotiation, for it has a good share of hearty dungeon exploration as well. Pgs. 4-23

Nearly 100 years ago, Lord Eriador wrested the lands from the hands of evil and began a reign of unsurpassed courage, wisdom, and might that lasted over three centuries. One day this great man of valor was called onward to continue his battle for freedom and goodness on a higher plane of existence. Leaving the responsibilities of rulership to his faithful overseer, he donned his magical shield, helm, and sword and traveled to the Holy Maountain of Anduin to meet his destiny. Eriador left the overseer with this solemn promise: if there ever arose a time of great need, he would answer a summons from the Mountain of Anduin to come back to vanquish any evil that dared to oppress his people. It is now the reign of the third overseer. For years now, an evil mage has been plaguing the land by sending forth hordes of evil humanoid minions to oppress the people. The overseer has been forced to pay tribute to the mage to protect his people. Life has become nearly unbearable for his subjects. It has been over five years since the mage desecrated the holy mountain by placing foul creatures in its depths to guard against the possibility of the people seeking help from their nearly forgotten champion. A fortnight ago, your party was gathered in a secret council chamber to meet with the overseer himself. You felt a spark of hope for the people of this land as the overseer told the legendary tale of Eriador. He gave you the equipment you need and charged your party with the task of venturing into the heart of the now monster-infested Mountain of Anduin to call back the people's great hero, Eriador the Paladin. Although the three parties sent before you had not returned, ridding the of the land of the mage seemed worth any risk, and you eagerly set out on your quest. Now, standing before the defiled mountain, you wonder if perhaps you were too hasty.
