The Secrets Stones Keep

Deep beneath the orc city of Urgir in the Hold of Belkzen lie the ruins of the ancient dwarven Sky Citadel of Koldukar, where awaits what could be the greatest discovery of the Age of Lost Omens: confirmation of the location of one of the lost Sky Citadels, built by the dwarves in their earliest days on the surface of Golarion. But reaching their destination won't be easy for the Pathfinders, and only the most skilled will survive Urgir and the terrors guarding the dwarves' long-abandoned secrets. Can they uncover the location of the lost Sky Citadel, or will the Pathfinders suffer the same fate as Koldukar—defeat at the hands of ruthless orcs and centuries of decay under the earth?
