PCs should advance to 13th level by the end of this adventure. “Blood for Blood” begins with the PCs having returned home from solving the mystery of the Varnhold Vanishing. Shortly after their arrival, they learn that new problems have developed during their absence—there are rumors of an army marching toward their nation!The PCs race to the village of Tatzlford, where they help defend the village from an attack by a small but earnest force of bandits, barbarians, and several lumbering trolls after being warned in advance by a troubled woman who has fled from Fort Drelev to the west. Following the skirmish, she pleads with the PCs to save her father and sister from peril.From there, the PCs strike out into the swamplands of the Slough to the west, exploring new lands and finding opportunities to make new allies and eliminate long-term threats to the region. Their initial goal, though, should be infiltrating Fort Drelev, where they’ll have a chance to confront the traitor Drelev with his crimes and rescue the Fort’s beleaguered settlers. During this time, the PCs learn where Armag’s tribe has been holding the daughters of Drelev’s senior officers hostage. Arriving at the ancient site, the PCs attack Armag’s barbarian encampment and overcome the sinister powers of the Black Sisters to free the girls. Then, entering the tomb, they face deadly traps, ancient undead horrors from a war-torn age, and the trials of the tomb’s immortal, divine guardian.

Panic grips Absalom when a huge crystalline sailing vessel appears suddenly in the harbor. Identified as the King Xeros of Old Azlant, the ship presents a great opportunity for the Pathfinder Society. You and your fellow adventurers are summoned by Venture-Captain Adril Hestram and dropped aboard the King Xeros to explore it and report back. Only, what you find isn't an empty vessel, but a sinister ship with a vile intent. Difficult and unforgiving scenario, typical of Greg A. Vaughan. Contains lots of monsters from the Ethereal Plane and a mysterious setting. If playing under Pathfinder Society rules, a six-player party is recommended, rather than the standard four for early PFS seasons. Using Pathfinder RPG versions of monsters reduces the lethality, as the constructs are no longer immune to critical hits and sneak attack damage, and the Xill no longer automatically bite for paralysis on a maintained grapple.

When Pathfinder alchemist Andrax d'Aponte contracted a mysterious wasting sickness, he set his mind to feverishly researching the disease and its cures. With the rare skeleton moon hanging in the sky above Absalom, the Decemvirate sends you to an ancient siege castle outside the city to recover d'Aponte's research notes and inquire about his involvement in recent Pathfinder deaths in Osirion.

There are those in town who claim the falling star was in fact a ship, and now a strange malady is creeping through the townsfolk.

The few surviving rangers need heroes to help them retake this key fortification before the ogres use it as a staging ground for further assaults on the region.

When Harrowstone Prison burned to the ground, prisoners, guards, and a host of vicious madmen met a terrifying end. In the years since, the nearby town of Ravengro has shunned the fire-scarred ruins, telling tales of unquiet spirits that wander abandoned cellblocks.

A Pathfinder Roleplaying Game adventure for 4th-level characters, this volume of Pathfinder Adventure Path is part 2 of 6 of the Kingmaker Adventure Path, in which the heroes win and defend a small kingdom from threats foreign and domestic. PCs should advance to 7th level by the end of this adventure.

Wicked fey inhabiting a ruined keep, undead haunting an ancient barrow mound, and others must be defeated to make the region ever more secure. Along the way, the PCs might also have the opportunity to ally themselves with some of the region’s local residents, including the dryad druid Tiressia, her satyr consort Falchos, and a band of gnome explorers called the Narthropple Expedition. In addition, the PCs will be called upon to mediate between two rival factions in the area: a group of independent loggers and the angry fey sorceress who opposes them. As they explore, evidence that a group of trolls is stirring up trouble in the region becomes apparent. Meanwhile, the PCs must deal with events within their burgeoning kingdom—a rabble rouser seeks to oust the PCs from their positions of power, the secretive cult of the hag goddess Gyronna has infiltrated the town, and a werewolf is preying on the townsfolk. All of these events build to the adventure’s twin climaxes: the sudden assault on their capital city by an owlbear of unprecedented size and the expansion of Hargulka’s trolls into the north. Faced with danger on multiple fronts, the PCs must draw upon all of their resources and bravery to become the undisputed rulers of the Greenbelt.

Impossible Experiments is a series of adventures, each spanning 1-2 levels. Each volume can be run individually or combined into an ongoing series. This volume establishes the premise of this series… When the wizard-king Nex retreated into his Refuge over 4,000 years ago, speculation ran rampant as to what he would do in this space. At first, many assumed that he was restrategizing for the war with Geb, but as the decades and centuries ground on, wilder hypotheses were offered. One explanation claimed that Nex was experimenting to develop a new generation of magical warriors, spies, and minions whose presence would overwhelmingly tip the scales of war against Geb, and likely other nations to follow. In recent years, the gates to the Refuge of Nex have opened, and strange creatures have emerged. Indeed, these creatures are prototypes that Nex is evaluating. Near the iruxi-founded town of Gitna, one of Nex’s first prototypes has emerged and begun to claim victims. The guard has been raised in Gitna, and the heroes are now called to fulfill their oath to defend the town by helping one of its behir guardians, recently injured in his own fight... This adventure includes two archetypes, a versatile heritage, backgrounds, and items you can offer to your players to make this adventure your own!
