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. While traveling through the briar-covered woods, the party reaches a clearing where a rabbit challenges Balian to an honorable duel. Miniatures and scenery are by Reaper, Warhammer, Dark Sword and Tabletop World. 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.
