None know from where the Heresiarch first came, but all remember the night that it did. It rode down from the bleeding stars on a great serpent, hurling bolts of obsidian lightning that shattered the monuments and capitols of every nation. Its infernal army swept aside the defenses of the mortal empires in a single hour, decimating legions once thought to be the invincible fist of humanity's god-kings. Faceless priests - each bearing the symbol of the trident - drifted through the fallen cities and scorched villages on a frigid wind, and when they rose to greet the huddled men and women ringed by their festering, bloated dead, they spoke a single, simple offer: worship the Heresiarch or die. Thousands of crusaders fell tonight so that you might be given this chance. In a last stand that, for the first time, united all of the empires of humanity as brothers and sisters, a way was cleared into an infernal stronghold said to contain a gate to the Heresiarch’s fane. All is silent save for the clangor of distant battle. Surrounded by grim-faced knights and teary-eyed peasants – their hands clasped in desperate hope – you step through the glowing, churning doorway, knowing there will be no help and likely no return.

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.

This adventure has a lighter tone but isn’t completely out of place in a serious campaign. The challenges include combat, puzzles, traps and a legendary monster; Jack, in a Box. Does the party need to find something that an evil (and possibly mad) mage may have secluded away in an extra-dimensional space, and ordered an evil Jack-in-the-box and his toy army to protect it at all costs? Well that’s convenient because that is exactly the kind of situation that "Trapped in the Toybox" can help you with. Alternatively maybe that Dragon fight went a little too well for your party, maybe this “cursed chest” could help teach them a little humility. This adventure is designed for 4 (1d6 + 1) adventurers of 8th level who are in possession of a sense of humour. The toybox was created by a chaotic yet playful wizard, in order to hide an enchanted amulet under the protection of Jack. The adventurers should find themselves trapped inside the toybox, and they're in Jack's world now. Jack is the master of this domain and protector of both the amulet he has been entrusted with and the only exit of the toybox. There are a number of ways the adventurers may have come to be inside this toybox, e.g., the toybox may be found as part of the adventurer's loot in a dungeon or dragon's hoard, upon investigation it drags the adventurers inside. Note: This module commemorates our first themed week of Reddit's /r/Monsteraday and ties together this week's monsters in a dungeon designed for four 8th level adventurers. https://www.reddit.com/r/1d6Adventurers/comments/61axk3/trapped_in_the_toybox_adventure_module/ Published by 1d6Adventures

Deep under the ruins of Maure Castle lie the Chambers of Antiquities, vaults designed by ancient wizards to store magic items even they didn't quite understand. A continuation of last year's hit "Maure Castle." This adventure is set under the infamous ruins of Maure Castle, a monolithic edifice of night-black granite built by a powerful family of wizards. The Maures sealed themselves into the dungeons below their castle long ago, and today these dungeons have become one of the most infamous adventuring sites in the land. Although estimates have placed the number of monster-infested and trap-haunted dungeon levels below Maure Castle at 17, there may in fact be even more. This adventure presents one of those dungeon levels in detail. Pgs. 76-101
