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 search of another blood coin, the companions travel to the Smith’s Caldera. Drawing the Harrow card of the ‘Forge’, Sjo and Balian manage to heat up the fire to blazing hot temperatures. Miniatures and scenery are by Dwarven Forge, Psomminiature, Twisting Catacombs, Reaper and Warhammer. 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.
