After a recent discovery of a lost city in the heart of the demon-infested Worldwound, Pathfinder agents from around the world flock to Nerosyan, capital of the crusader nation of Mendev, to prepare for the coming adventure. When the city falls under attack, however, everyone within its walls must take up arms to defend against the Abyssal hordes. Do the Pathfinders have what it takes to hold back the demonic onslaught, or will their souls be among the first to be consumed when the Diamond of the North falls?

The failure of Mendev's wardstones set in motion not only a new crusade but also catalyzed a change in the Pathfinder Society's various factions. As the Pathfinders prepare to march on the Sky Citadel Jormurdun, members of the various factions scramble to consolidate their gains and neutralize their enemies. "The Paths We Choose" is a special event designed to highlight the changes in each faction over the course of Season 5, The Year of the Demon, and the adventure is different for each group depending on which factions are represented at the table. Content in "The Paths We Choose" also contributes directly to the ongoing storylines of the Andoran, Cheliax, Osirion, Qadira, Sczarni, and Taldor factions.

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.

The innumerable cairns and burial mounds of Barrowmoor in northern Nidal contain untold treasures and terrors, and the local taboos and Nidalese theocracy are typically enough to keep any but the boldest from exploring the site; however, when the Blakros family informs the Pathfinder Society that their shared enemy is in pursuit of a dangerous artifact, the PCs must brave the shadow-stricken region to keep this object from falling into the wrong hands.

Two foes of the Pathfinder Society race toward the dwarven Sky Citadel Jormurdun, aiming to snatch away the Pathfinders' prize. The Society dispatches its best agents to intercept the duo. Can the PCs prevent their enemies from ruining the expedition and put an end to the threat posed by these villains?

The Pathfinder Society embarks on its expedition to the lost Sky Citadel Jormurdun with a small army of allies in tow, but they are not the only ones seeking the dwarven fortress. Two of the Society’s nemeses have rallied the fiends of Frostmire to crush the Pathfinders, hoping to buy the villains enough time to secure Jormurdun first. If the campaign is to succeed, the Society’s forces will need bold leadership. Can the PCs lead their motley army to victory deep in the Worldwound?

The fiery inquisitions that raged through Mendev during the Third Mendevian Crusade may have been damped but never truly extinguished. Fanatics have reignited the witch-hunts in eastern Mendev, and in doing so they have captured and accused allies of the Pathfinder Society. Unless the PCs intercede and put a stop to this mob justice, their allies' deaths will spark a new wave of internecine executions throughout the crusader nation.

When the daring half-orc scholar Ulisha enrages a noble family in the River Kingdoms, she contacts the PCs with a special deal: she will sell them a unique and ancient druidic relic at a steep discount to secure the gold she needs to pay off her bounty. By the time the PCs arrive to meet her, she has gone into hiding. However, she has left behind a journal full of profitable leads as a sign of good faith. Can the PCs recover this hidden wealth and claim the powerful Silverhex before an assassin finds their friend?

Guaril Karela, a close ally of the Pathfinder Society and the leader of the Sczarni faction, made dangerous enemies during his bid for territory and influence, and several of the rivals that he once thought defeated have returned with every intention of ending Guaril’s little empire and his life. The PCs must travel to the dangerous city of Kaer Maga, track down these assassins, and sabotage their efforts in order to save one of the Society’s most reliable spymasters.

For months Taldor faction leader Lady Gloriana Morilla has mustered a small army to aid the Mendevian Crusade; however, without a powerful, unifying icon to rally around, progress is slow. When her agents learned of a dormant relic that might be awakened, she petitioned the Pathfinder Society for its aid in recovering this so-called Horn of Aroden, knowing that the Society would benefit from her army’s hastened arrival. The PCs travel to Brevoy, a fragmented land of dueling, cold, and conquest to secure this horn, though in doing so they join an ongoing plot of politics and intrigue.
