The Ironfang Legion’s secret weapon has been revealed! An ancient dwarven artifact known as the Stone Road allows the hobgoblins to move their forces hundreds of miles at a time, completely unseen. Whatever secrets—and vulnerabilities—the Stone Road may have lie sealed within the dwarven Sky Citadel of Kraggodan. To enter the besieged fortress-city, the heroes must brave the dangers of the Darklands, including morlock fanatics and their slithering god, and duergar slavers, only to find what they need in long-abandoned corners of the ancient city now dominated by horrors from deep below!

“Siege of Stone” is a Pathfinder Roleplaying Game adventure for 11th-level characters. The adventure continues the Ironfang Invasion Adventure Path, a war-torn homage to classic fantasy adventure in which the heroes defend their homeland from a savage invading army. An ecology of the enigmatic naga, a gazetteer examining the dwarven Sky Citadel of Kraggodan, and selection of new monsters round out this volume of the Pathfinder Adventure Path!

Each monthly full-color softcover Pathfinder Adventure Path volume contains an in-depth adventure scenario, stats for several new monsters, and support articles meant to give Game Masters additional material to expand their campaign. Pathfinder Adventure Path volumes use the Open Game License and work with both the Pathfinder RPG and the world’s oldest fantasy RPG.
