Thunderspire Mountain lies to the East of Fallcrest, close to the trade route between Fallcrest and Hammerfast.
It lies amid a wilderness of pine forests and rocky hills. The mountain’s pinnacle is usually wreathed in gray, forbidding clouds, but on rare clear days it can be seen from a great distance.
The Trade Road, an old dwarf-made highway, passes near the mountain. In years past, travellers and caravans hurried past Thunderspire to avoid attacks from monsters lurking in the ruined Minotaur City. Today, this part of the road is reasonably safe thanks to the presence of the Mages of Saruun.
From the Trade Road, a steep cobbled path called the Vale Road turns north and cuts into the Mountain. The road rises through a valley with sparse vegetation and ends at Thunderspire’s base. Small waterfalls and brooks wash down from the rocks above. A few shepherds, woodcutters and trappers live in the Vale. Their humble houses are made of turf and fieldstone and are fitted with stout door to repel predators, including bears, wyverns and griffons.
The ruins of Saruun Khel beyond the Seven Pillared Hall are collectively called the Thunderspire Labyrinth. The ancient Minotaur city consisted of a vast maze of natural caverns, gaping chasms, hewn chambers, steep stairs and twisting passages. Most of these features remain to this day. The Seven-Pillared Hall and its adjoining chambers form a small part of Saruun Khel. Much of the Labyrinth remains dangerous and unexplored. There are no surviving maps.
