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.
