The tradition of Adventure Paths was begun by Paizo when they published the official Dungeons & Dragons periodicals Dungeon and Dragon. When these magazines were discontinued in summer 2007, Paizo continued the popular tradition, now set in their own proprietary game setting—the world of Golarion. The line was originally titled simply Pathfinder but was changed to the current Pathfinder Adventure Path when additional Pathfinder-branded product lines were introduced.
