The way through the Iron Mountains has been impassable for months. Surely you can help the enterprising merchant Jannah the Red evade or overcome the bandits of Justaios the Rebel.

The Queen of the Lost Valley also includes a Book of Lore discussing the Iron Mountains, their savage people and a host of strange forgotten places.
