Seeking answers, the player characters search the hallowed forests of Sevenarches, finding paranoid townsfolk, violent druids, and an enigmatic bogeyman pulling strings from the shadows. Can the party unravel the schemes of Kaneepo the Slim? How does an ancient curse relate to their missing memories? And what awaits them beyond the Seventh Arch? The Gatewalkers Adventure Path begins in "The Seventh Arch," a complete adventure for 1st- to 4th-level characters.
