Season ten

10-00: The Hao Jin Cataclysm by Mike Kimmel
For levels 1-11. Many centuries ago, the legendary sorceress Hao Jin crafted a museum demiplane, ripping locations from across Golarion to add to her personal collection. When she vanished without a trace, the demiplane began falling into disrepair. Ever since the Pathfinder Society gained access to this realm seven years ago, its agents have been gradually exploring the demiplane's wonders, meeting its people, and cataloging its preserved historical relics.

Former Pathfinder Master of Spells Aram Zey has just made a terrible discovery—the demiplane's deterioration has reached a critical stage. Unless the Pathfinder Society intervenes, the entire demiplane will rip apart violently, ejecting most of its contents into the Astral Plane and killing everyone inside. Yet it isn't as simple as sewing the demiplane back together with some metaphysical thread. Powerful forces from both within the tapestry and outside of it seek to hasten the destruction or profit off the chaos, and the impending apocalypse has thrown the tapestry's civilizations into turmoil.

10-01: Oathbreakers Die by Nicholas Wasko
For levels 1-5. The city of Daggermark is best known for its poisoners and assassins, who maintain active guilds that enjoy the full respect of local authorities. Local venture-captain Istivil Bosk prefers to keep his head down and stays out of their affairs, but he has recently learned that a Pathfinder agent has been targeted for assassination. Can the PCs enact the venture-captain's daring plot to save this agent without becoming the assassins' next victims?

10-02: Bones of Biting Ants by Sean McGowan
For levels 3-7. The sole survivor of an ill-fated Society expedition into the Mwangi expanse barely managed to return home years ago, bringing little to show but an unpleasant affliction and haunting memories, neither of which they could shake. While the agent had planned to retire from the Society for good, they now seek assistance in finding closure, seeking a cure, and recovering the relics the team had to abandon. What sounds at first like a simple recovery mission becomes far more complicated, for the same threats that spelled disaster for the first mission are as dangerous today.

10-03: Death On The Ice by Scott Young
For levels 5-9. A message delivered by an unlikely courier sends the PCs to the Crown of the World. After making a dangerous trek across the icy passes and bays of Golarion's northernmost continent, the PCs must come to the aid of a Pathfinder Society expedition whose archaeological excavations have uncovered far more than they expected to find. Can the PCs unravel the mysteries that lie beneath the gelid glaciers of the Crown of the World in time to save their fellow Pathfinders from a frigid fate?

10-04: Reaver's Roar by Steven Hammond
For levels 7-11. A call from some of the Pathfinder Society's most esteemed leaders brings the PCs to a small town in Lastwall. While their mission to retrieve a relic of the Shining Crusade from a cathedral guarded by a fearsome beast seems straightforward—if extremely hazardous—interested parties from the nearby orc nation of Belkzen and beyond have their own plans that may not align with the PCs' own. Will the Pathfinders survive the deadly onslaught of a territorial guardian, or will they play into the hands of even more sinister forces?

Contents in Reaver's Roar also contribute directly to the ongoing storyline of the Silver Crusade faction.

10-05: Mysteries Under Moonlight, Part 1: Testament of Souls by Alex Augunas
For levels 3-7. Something ominous is afoot around Magnimar's famous monuments. The mayor hired an official investigator to get to the bottom of the situation, but the latter's methods have overlooked key evidence. Unable to secure the investigator's cooperation, a local governing body called the Varisian Council has turned to the Pathfinder Society for aid. The Pathfinder Society's efforts to cleanse the monuments and discover the source of their corruption are certain to stir up trouble as the PCs draw closer to a confrontation with a lurking evil force.

Testament of Souls is the first scenario in the two-part Mysteries Under Moonlight campaign arc. It is followed by Pathfinder Society Scenario #10-07: The Howling Dance. Both chapters are intended to be played in order.

10-07: Mysteries Under Moonlight, Part 2: The Howling Dance by Crystal Malarsky
For levels 3-7. With the unique blessing of a celestial ambassador, the PCs depart Magnimar and rush into the swamp, chasing after the mastermind behind the corruption of several of Magnimar's iconic monuments. This mastermind isn't the only one who wants to see the PCs perish in the swamp, however. If the PCs are to find the mastermind and undo these schemes, they'll need to keep their wits sharp and make the most of their newfound powers.

"The Howling Dance" is the first scenario in the two-part "Mysteries Under Moonlight" campaign arc. It is preceded by Pathfinder Society Scenario #10-05: Testament of Souls. Both chapters are intended to be played in order.

10–06: Treason’s Chains by Adam Meyers
For levels 1-5. Venture-Captain Roderus has long been one of the most reliable and steadfast allies of the Pathfinder Society in the nation of Katapesh, but the aging human has decided that it is time to retire from his long-held position. Roderus's retirement party draws in Pathfinders from across Golarion, but there are some who see his retirement as an opportunity to advance personal goals that go against the Pathfinder Society's interests. Amid the turmoil of a party turned crime scene, the PCs must uncover the true threat to the Society's stability in Katapesh—and perhaps make an unexpected new ally along the way.
