Pathfinder Society Roleplaying Guild scenarios are small, four-to-five hour monthly adventure publications released two at a time. Each scenario contains a stand-alone adventure which can be run as a self-contained story or as part of a larger ongoing series of adventures. Each year from August through July, the Pathfinder Society Roleplaying Guild program creates a new "season" of adventures that relate or directly tie into an over-arching story that previous players have woven. This story changes, however, depending on the actions of the Pathfinders (or players) around the world. Its tenth season (Year of the Ten) began in August 2018.
As part of the yearly RPG Superstar game design talent search conducted by Paizo, the top three runners-up earn the privilege of writing an adventure that is published in the following Roleplaying Guild season.
During the late spring and early summer months, Paizo releases the last four scenarios of a season at its yearly convention, PaizoCon. To start off a new season, Paizo also releases between four to seven new scenarios at each year's Gen Con. This includes a introductory special scenario for the upcoming season that allows for multiple tables of players to play the same scenario and their actions influence the scenario's overall success. This scenario sparks the events of the upcoming season and lays the foundation for future missions.
Beginning in 2013 and spanning until GenCon 2014, Paizo released special, "Convention Only" scenarios in the Bonekeep series to entice players to play at regional conventions. These scenarios were designed to test the very best Pathfinders, offering greater rewards if the player survives the entire adventure.
Pathfinder Society Roleplaying Guild's season numbering reset after the release of Pathfinder Second Edition in August 2019, starting with the next season, Year of the Open Road, as the next Season 1.
