While many adventuring parties are just created on the spot and stick together as they travel the world, in Pathfinder, there's an organized group of adventurers whose job it is to boldly go where no one has gone before. To seek out life and new civilizations. They are the Pathfinder Society, and they are getting their own Lost Omens book. You can check it out in this preview.
From the article:
The goal of Lost Omens Pathfinder Society Guide is to provide a comprehensive snapshot of the ins and outs of this organization, from the twists of its history to its many everyday operations. For those interested in having their characters join the Pathfinder Society, the first two chapters present a detailed look at life in the Society as a whole, from daily routines and yearly holidays to the many branches of training that Pathfinder recruits are expected to familiarize themselves with. Even those adventurers with little interest in the Society might find themselves picking up a useful trick or two from a Pathfinder ally or rival. Might your character learn a bit of the Society's silent Napsu-Sign to quietly communicate danger to allies (or communicate more accessibly to the deaf and mute)? Could one find a weakness-seeking alignment ampoule useful on her adventures?
Even those characters who find their calling elsewhere are likely to encounter one of the Pathfinders' many lodges on their adventures! From the frozen Lands of the Linnorm Kings to the impossible kingdom of Nex, Pathfinder strongholds can be found, harboring dozens of agents as they prepare to explore even more distant locales. These lodges are more than just a welcome spot of reprieve and resupply for the weary hero—no matter how subtle, the works of the local Pathfinder lodge always have an impact on local politics. From the political turmoil that the seemingly ill-fated Exalted Lodge is causing in Razmiran to Starrise Spire's increasingly tenuous claim to one of Mendev's grandest fortifications, the presence of the Pathfinders provides multiple plot hooks for other heroes to become involved in, be they allies, enemies, or entirely disinterested in the Pathfinder Society itself!
