More than a millennium has passed since the "machine mage" Karamoss's failed siege of Absalom, and for years the Pathfinder Society has used upper reaches of his subterranean siege tower as a training ground for initiates. During a routine drill, the once-dormant dungeon springs to life, and it will take all the PCs' resourcefulness and skill to make it out alive.

Part of a Numerian relic once thought scattered to the winds has found its way back to the savage land of super-science, and the Pathfinder Society must track down the component if they are to unlock the device’s secrets. Clues point to the economic hub Chesed, where only the descendants of a shattered clan can share where their revered ancestor buried the strange artifact. Can the PCs brave the troubled city, evade the vigilant agents of the Technic League, and survive a trip into the Numerian wastes? Content in “Returned to Sky” contributes directly to the Year of the Sky Key metaplot as well as the ongoing storyline of the Exchange, Liberty’s Edge, and Silver Crusade factions.

The esteemed Blakros family—famous for their museum in Absalom—receives a large shipment of artifacts from Numeria but fears that the ever-vigilant Technic League will attack to reclaim its "stolen" property. When they request the help of Pathfinders to help guard the collection, the PCs discover that the Technic League is the least of their worries. Content in “The Silver Mount Collection” contains faction missions for the Dark Archive.
