You and your fellow Pathfinders are sent to Katheer, the shining capital of Qadira, to witness the wedding of Pathfinder Faireven to the wealthy and beautiful Lady of Silver and bring back a trove of relics given to the Society as part of the wedding dowry. When the wedding is disrupted by unscrupulous thieves, you soon find yourself dodging double-crosses, accusations of grave robbery, and worse. You must find the relics soon, or risk facing the eternal expulsion of the Society from the treasure-filled deserts of Qadira.
When a Qadiran Pathfinder known for her knowledge of genie-kind fails to report back to the Katheer Lodge, the PCs are sent into the long-abandoned ruins of Koor, a former forge city high in the Zho Mountains. In their effort to find the lost agent, the Pathfinders may find themselves facing a foe long locked in a secure vault by the city’s former occupants—guardians whose departure weakened their defenses, paving the way for a terrible escape.
When the Worldwound opened, tearing apart Sarkoris with a flood of demons, thousands of Sarkorian refugees sought shelter in nearby lands. Those who found no solace with their neighbors traveled far to the east, into the wilds of Iobaria. Among these was the Farheaven clan, which settled in the forests and faded into obscurity over the past century. Now that the Mendevian Crusades have fought back the demons and reclaimed a large amount of territory, the Pathfinder Society's begun the difficult task of studying the Sarkorian ruins to piece back together their shattered traditions and recover lost heirlooms.
Unfortunately, the Farheaven clan's old stronghold holds secrets that archaeology struggles to decipher. To understand this culture, the PCs travel to Iobaria in search of the Farheavens and the oral histories they've passed down for generations. What they find, though, are a devastated people, an abandoned village, and a murderous god. Can the PCs save this clan and preserve its history?
Now possessing key information about the mysteries of the Scoured Stars, the Starfinder Society sends the PCs to a distant star system in the Vast. The idea that the non-spacefaring natives of this system have any connection with the distant Scoured Stars seems unlikely, but it's up to the PCs to confirm if a connection does exist. Other factions complicate the situation by having their own unique agendas relating to the distant world and its peaceful inhabitants.
Content in On the Trail of History also contributes to the ongoing goals of the Second Seekers (Luwazi Elsebo) faction. Content in this scenario also contributes to the ongoing year of the Scoured Stars storyline.
