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. The adventurers make their way to the Prophet’s Garden, hoping to find one of the blood coins, which will allow them to leave this plane. Miniatures and scenery are by Reaper, Warhammer, Dwarven Forge, Dungeons and Dragons and Pathfinder Battles. If you want to find out more about this fantastic adventure, you can go to the campaign journal section of Paizo's messageboards under MrVergee's Curse of the Crimson Throne.
