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. Against the faded blue painted dome that forms sky a stylized version of the sun rests on a mechanical arm. Miniatures and scenery are by Scotia Grendel, Warhammer, Reaper, Psomminiature, Dwarven Forge, 4Ground, Tabletop World 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.
