The Pathfinder Adventure Card Society (PACS), formerly known as Pathfinder Society Adventure Card Guild (PFSACG), is a worldwide program of sanctioned, organized Pathfinder Adventure Card Game play for retail stores, conventions, and home play. The guild debuted on October 1, 2014.
Season 0: Season of the Shackles
"Season of the Shackles" debuted October 1, 2014, and provides new gameplay scenarios and stories for organizers who own the Skull & Shackles Base Set and players who own a class deck. New chapters will be released on the same day as each new Skull & Shackles adventure deck, and new scenarios will be featured each week until the Wrath of the Righteous Base Set is released in 2015. Guild content will released for home play a month after it is provided to retailers.
Paizo released a Guide to Pathfinder Society Adventure Card Guild Organized Play on August 11, 2014, to support Season 0.
