Overview
Living campaigns are a shared campaign setting with a codified set of rules for the campaign that govern how to build and advance characters as well as how the campaign will handle rules elements of the setting. Campaign staff create, distribute, and manage new adventures in that campaign setting, and quite often administer a player database and promote various products. A living campaign lets players build and advance characters, develop their personalities, and forge relationships. Living campaign games are run at conventions, game days and other gatherings. The rules for character tracking allow a player to take their PC they created for the campaign to any of these gatherings and play it in the adventures offered. It is still common for adventures to be offered at conventions with premade characters that fit to the story, but Living campaigns allow for additional options.
