The Adventurers are a part of Eorzea's peacekeeping forces. Made up entirely of volunteers, the Adventurers have a guild in all of the major cities of Eorzea. They perform all manner of tasks, from creating items, to delivering them, to combating monsters, Adventurers wander the realm to find and aid those in need. A small subset of these Adventurers have the Echo, and are called upon by the Warrior of Light when they need backup fighting Primals, the local physical manifestations of gods.
The Adventurers are the only branch of Eorzea's military and peacekeeping forces not beholden to any nation or chain of command. As such, they are free to cross borders and help anyone in any way they wish, with the only real oversight being other Adventurers as well as the guild. The Adventurers have also contributed to the restoration of several destroyed cities, such as Revenant's Toll and Idyllshire.
They are also expected to participate in the upcoming campaigns against the Garlean empire, focused on retaking the fallen city-state of Ala Mhigo as well as the foreign nation of Doma.
