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.

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.

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.
