Pathfinder Adventure Path #86: Lords of Rust (Iron Gods 2 of 6)

The heroes of the town of Torch follow a trail of clues to the sprawling junkyard known as Scrapwall, where bands of desperate and violent brigands vie for control of the technological remnants found within. The Lords of Rust dominate Scrapwall, and their swiftly rising power threatens more than just the town of Torch, for this gang has the support of one of the terrifying Gods of Numeria. What slumbers fitfully beneath the wreckage of Scrapwall could catapult the Lords of Rust into a new level of power if they're not stopped!
