You can assemble these in any configuration you like, either randomly or not, either before the campaign or on-the-fly in play. You can also use these sectiosn on their own, without reference to the larger dungeon itself.

Combined with the unique monsters located in specific dungeon sections, this book contains over 150 different monster stat blocks. There are criminal organizations, insane cultists, meddling deities, evil wizards, undead kings, infernal demons and other invaders from beyond the stars, numerous unspeakable horrors and arcane beasts, and even a few rival adventurers. Use these monsters with this dungeon or any other. Specific conversion guidelines for The Nightmares Underneath are also provided.

Many centuries ago, the dwarven kingdom of Sarphil stretched out across the Galena Mountains east of the Moonsea. They dug for the precious metals hidden beneath the rocky terrain, and they established numerous cities and settlements to aid in their excavation and manufacturing efforts. This was during the early days of Myth Drannor, the elven kingdom in the forest of Cormanthor, and the dwarves and elves initially clashed as each sought resources and expanded their territories. Myth Drannor and Sarphil eventually settled their differences, and many dwarves moved into the elven city to offer their services and expand their knowledge. In the Galena Mountains, Sarphil continued to flourish. Unfortunately, these days of prosperity did not last long. The last great king of Sarphil was lost in the dwarven city of Mount Throndor, beneath the mountain peak of the same name, and Sarphil withered under bitter clan disputes since no single family could claim legitimate lineage over the fragmented kingdom. What happened under Mount Throndor has been a mystery for thousands of years. Many attempts have been made to reclaim the lost riches and legacy of the last Sarphilan king, but powerful wards have prevented intrusion under the mountain, wards erected by the dwarves of Sarphil. Were the wards built to keep outsiders from intruding – or to keep something inside from escaping? An enterprising dwarven leader wants to find out, but she is going to need some help from a band of heroes. Horrors of Mount Throndor is a Dungeons & Dragons adventure of exploration, darkness, and terror featuring a lost dwarven city overrun by forces from the Far Realm and the journey to cleanse it once and for all. The adventure is designed for a group of 11th-level characters, and successful completion of the adventure should put the characters at 16th level. Here There Be Monsters Mount Throndor has become infested with madness from the Far Realm. During their journey to penetrate the ward and through the city itself, the characters are going to face gibbering horrors, unpredictable slaadi, fanatic stone giant cultists, degenerate star spawn horrors, mutant derro, undead dwarves, and countless golems. The ancient breweries of Mount Throndor have produced alementals who slither in the darkness, and a great dwarven war juggernaut named Big Hans stomps through the city. Legendary Villains and Epic Moments Though it has been sealed, Mount Throndor is not empty. The characters have opportunities to meet, interact with, and (likely at least) combat against powerful foes within the legendary dwarf city. A dwarf lich, a Far Realm spider goddess, an iron-encased demilich, and a melted flesh derro warlock monstrosity all await, along with a mind-bending force - Great Cthulhu! The characters have a chance to face an avatar of Great Cthulhu in the dwarven depths in the final confrontation of the adventure to free Mount Throndor and rid Faerun of a Far Realm invasion! An Adventure of Exploration Mount Throndor is a big, sprawling complex, a dwarven city with two major strongholds, a bridge system spanning a massive underground lake, and a deep mining complex. The scale is difficult to grasp and convey. Previous examples of adventures featuring these elements have included maps - usually lots of them, great spawling maps connected at ends to make huge subterranean dungeons. It is the classic image of a D&D dungeon crawl, and the map is a key component to its visualization. However, in this adventure, the maps are handled differently. There are certain areas, ususally outside the dwarven city itself, that include maps that are suitable for use at the game table, either in theater of the mind style or grid-and-miniatures. Mount Throndor itself is presented with an abstract map, and exploring it utilizes the exploration procedure outlined in Appendix A. Characters traverse the huge subterranean system using this abstract system, and during their travels they are going to run into random encounters and sites with more interesting and complex encounters.

Last Gasp is an adventure set in a desert setting, exploring the cursed tomb of an ancient king of great magical power, a magical river, and includes both deadly combats and mysteries to confound tomb-robbers. Seek out the riches of a king, and may fortune favor you!

A Gritty OSR Fantasy Setting by Travis Legge The mortal lands are divided. A dozen kingdoms lie scattered across the world, separated by dangerous wilds filled with bandits and monsters. The bravest mortals act as adventurers, guiding travelers between the kingdoms, killing monsters to thin their numbers, and plundering ruins in search of the lost treasures of the golden age. This is the world of Odysseys & Overlords! The party are traveling west through the Untamed Gauntlet, on their way to somewhere else and using a stream to guide their steps. They step out from under the eaves of the forest to spy looming before them a cliff, a tall wall of stone which stretches away to either side as far as they can see. A waterfall cascades onto sharp rocks into a pool from which pours the stream they were following. The sheer cliff is easily 100 feet high, and too wet and slick to climb safely, though it can be tried. Atop the cliff is a bare stone hill which looks like it was at one time worked by intelligent hands; a look-out post of sorts has been carved into its southernmost peak. The map says it’s called “Wyvernseeker Rock,” but it doesn’t say why. The hill appears deserted. A long age ago, beyond mortal memory, a forgotten people built a watching post and refuge atop and within Wyvernseeker Rock. A hundred years ago, an adventurer named Olaf Wyvernseeker claimed the Rock for his own and set out with companions to clear the lands thereabouts. They were never heard from again. The upper chambers of the Rock are a convenient lair for a Giant Rhadogessa and its spider servants. Still, it’s got to be safer than climbing the cliff. Right? Published by Aegis Studios

A shrewd, spell-using green dragon has taken over the deepest chamber of a limestone cave as his lair. The dragon has persuaded a tribe of troglodytes to live in the outer chambers as a sort of "protective buffer" in return for gifts of magical treasure. The troglodytes cherish the useless bits of magic without realizing their modest worth. The outer chambers of the cave are protected by the troglodytes, the beetles and centipedes the troglodytes raise as cattle, and wild creatures. The green dragon uses traps, illusions and magical devices to protect his inner chamber. Wyrmhaven is the second dragon's lair to conquer. Part of TSR 1073 The Dragon's Den

This dungeon is suitable as a one-shot or drop-in for characters between levels 12 and 17. Taken from the Against the Idol of the Sun high-level hexcrawl campaign, the Death Knight's Tomb is a location-based exploration adventure.

There are six distinct sections to the dungeon containing four combat encounters of increasing difficulty. As written, the party enters the structure to rescue an overly adventurous Scorpionfolk couple and their rescuers, but they can be omitted or rewritten to any other species.

"Sometimes bugs are just bugs, and sometimes they are organized into a hive mind that is just as smart as humans. Ants are just that. In battle, the ants become a horde of raging combatants that form a blur on all sides. While ants are typically peaceful, they respond to a threat against the hive with a scale of violence that’s almost impossible to imagine. Utterly devoted to duty, ants never retreat from a confrontation—even in the face of certain death. Their engagements are brief and brutal. Working in teams, ants grab enemies, holding them in place until one of the warriors rips into the captive’s body, leaving it smashed and oozing." "Of Ants and Men begins as a quest to recover (e.g., steal) eggs from a giant anthill near the town of Endhome." "This adventure is designed for characters of levels 4 to 8." "The adventure can also be played (perhaps more effectively) by smaller groups. In response to many requests from our fans, the main encounters are designed to work well with groups of two to three characters of levels 6 to 8. Even a solo adventurer could do reasonably well, if the individual character had very good climbing, trap finding, and stealth skills. Druids, barbarians, and rogues will fare best in cases where the groups are limited in size." "While there’s plenty of opportunity for combat here, characters who think through a situation before drawing their swords are likely to do best. Hacking one’s way through is likely to result in character deaths."
