The road to the remote village of Swordfall is a long and winding one. It takes pilgrims who wish to visit the holy site from the main trade road, through the hills, and into the mountains where once, thousands of years ago, two gods engaged in an epic battle. Now, all that remains of the battlefield is a lone sword, several hundred feet tall, embedded in the ground at the center of a massive crater. Over the years, a large temple to Thuul, god of battle, sprung up around the site. Now, warriors and fighters from across the land travel to Swordfall to pay their respects once in their lifetime. Recently, however, pilgrims have begun going missing. Somewhere between the main road and Swordfall itself, something, or someone, has been waylaying travelers. Unbeknownst to most, a cult to Ghenna has taken over one of the lone inns along the route and has begun using it to capture and sacrifice pilgrims to their own dark god. Unless a group of adventurers can stop them, the sacrifices won't stop.

The end of the road. A lonely fort stands on the banks of a mighty river. It is here the hardy bands of adventurers gather to plan their conquests of The Hill, the hulking mass that looms over this tiny settlement. The Hill is filled with monsters, they say, and an evil witch makes her home there. Still, no visitor to The Hill has ever returned to prove the rumors are true or false. The thrill of discovery is too great to pass up, and only the river stands in the way. The adventurer's boat is waiting! This module is designed for use with the D&D Basic Rules. A trip through the wilderness begins a unique challenge for the novice player and Dungeon Master. TSR 9078

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.

Characters explore a dangerous, but sparsely populated temple in search of the Staff of the Dragon. They will encounter traps, environmental hazards, and a nest of lizardfolk. The characters are rewarded for a 'look but don't touch' approach to the temple's features. The real highlight, though, is the closing encounter. Once the staff of the dragon is retrieved, it can transform the characters into dragons for a set period of time. As they exit the temple, they are beset by an ancient dragon and the stage is set for an epic brawl as the characters take to the sky in dragon form. Can be completed as a one-shot.

Your time on the mainland of Calentria has come to an end and with an appropriated ship you find yourself approaching a collection of island in the middle of the ocean. Some of the sailors that have ventured into this area before report there may be a language barrier. As you approach a large land mass a dark shape in the sky seems to take notice of you…

Beneath our feet is the mythological hollow world – a realm of dense jungles, putrid swamps and rugged mountains. Here a brave party will struggle for survival as they seek to fathom the unseen expanse and to prevent a once defeated god to rise again. ‘Journey to the Inside Out’ can be played as a stand-alone scenario or be used as the first installment in a trilogy of connected adventure modules each taking place in a different era. The scenario can be used with Swords & Wizardry or any other early variant of game rules. Inside you will find: • A 40+ page old-school module with a layout optimized for fast and easy interfacing. • A challenging lost world setting with the possibility to toggle the complexity. • Alternative suggestions for entry to the hollow inside. • Downloadable maps for both players and the Referee. • Story-points for a guided scenario and tables for sandbox and hexcrawl-style play. • Advice for an ongoing campaign. • Locations allowing the PCs to travel to another era within the setting. • Unique new creatures.

Dragonbowl is a setting and pulp action adventure in one. It plunges a party into a rich festival scenario that revolves around a deadly gladiatorial contest, where the dangers they face in the arena are almost secondary to those they encounter in the murky criminal underworld they find themselves in: a world that stinks of corruption, human trafficking, illegal dinosaur-trading, necromancy, blood sacrifice and unnatural arcane experiments. The action takes place in a vast cavern in Mount Waterdeep, known as the Underbelly, where not only Dragonbowl Arena, but also an entire festival grounds – consisting of temples, bars, casinos, funfairs and markets - has been constructed to host this grand sporting extravaganza. With Xanathar, Jarlaxle, Davil, Volo and the Black Viper all in attendance, and scores of 'entanglements' (faction missions) to keep players busy, Dragonbowl can be played as a sequel to Waterdeep: Dragon Heist, or as a first step towards the Undermountain and the Dungeon of the Mad Mage. Equally, it can be played as a stand alone adventure, or easily transported into other settings. The adventure is written for a party of four 6th level adventurers, and easily customisable for three to five players, of any mid-tier level (the adventure contains maps and handouts adapted for both 4 and 5 player tables). The adventure is designed to last around ten to fifteen 4-hour sessions, but can very easily be shortened or lengthened according to the DM's desire. The adventure features all three pillars of play: combat (in and out of the arena), social interaction (a succession of parties and parades, where players can get entangled in NPC business) and exploration (30+ locations in the festival grounds alone).

Numerous towns sit in the shadow of Rak’Sarn, a mountain of flames and death. Each day near sunset, the volcano lets loose a blast of molten rock and ash, and the ancient red dragon Dal’Sarnquin swoops down the mountainside.

Storms frequently blow from the Cloudscape Mountains, but never one like this: For weeks it has hung over the peaks, casting its dark shadow across the land. Its huge black clouds billow and writhe in an effort to smother the sun. Once so picturesque and enchanting, the Cloudscape Mountains have taken on a sinister appearance. Fear now stalks the land. A malignant entity is growing and festering high in the mountain peaks. With dark tendrils, it reaches out towards the lowlands. No one is safe. Caravans are not arriving at the village of Lurneslye. It is only a matter of time before the villagers fall prey to the dark clouds and the evil they conceal. TSR 9151

Centuries ago, the despotic Alphaks, ruler of Alphatia, was banished to another world. From his own sphere of entropy he learned to manipulate men, and now seeks revenge against the human race. The volatile region of Norworld, a perennial battleground between Thyatis and Alphaita, draws Alphaks's attention. The already existing frictions, small-time political players, and petty vengeances are the sparks Alphaks will use to ignite a huge war that will destroy man-kind. This is an adventure of politics and diplomacy, of treachery and treason. Only courageous and bold actions can save Norworld from the horrors of war and liberate its people from oppression. The Vengeance of Alphaks may be played as a sequel to module M1, Into the Maelstrom, or separately. The D&D Master Set Rules are necessary for running this game. TSR 9148
