Paizo's adventure module 'The Harrowing' fits as a perfect sidetrek into 'The Curse of the Crimson Throne' adventure path. Looking for the disappeared fortune-teller Zellara, the PCs are drawn into the Harrowed Realm, a demiplane that is bound to the soothsayer’s deck of Harrow cards. In the center of the woods the party comes across the Midnight Circus. Inside the party has to impress the audience with tricks to avoid trouble. Miniatures and scenery are by Pathfinder Battles, Dungeons and Dragons, Warhammer, Reaper and Playmobil (converted circus tent). If you want to learn how this crazy adventure goes, you can go to the campaign journal section of Paizo's messageboards under MrVergee's Curse of the Crimson Throne.
