When a relic dating back to the times of Old Golarion docks in a remote space station, the Azlanti Star Empire takes notice and quickly seizes it. The Starfinder Society dispatches the PCs to stop the Azlanti and reclaim the relic: the ether ship known as the King Xeros. With little time to hamper the Azlanti's upgrades on the strange magical vessel, the PCs must overcome the now functional starship. Only by claiming the King Xeros can the Starfinder Society learn more about its predecessor organization's past.
King Xeros of Star Azlant is a spiritual successor to the Pathfinder Society Roleplaying Guild scenario, Pathfinder Society #20: King Xeros of Old Azlant. It also works as further content for players who've played, or are in the process of playing through, the Against the Aeon Throne adventure path.
