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 party makes it to their final destination, the Striding Fortress, a stone citadel which proudly marches through the desert on top of two gigantic mechanical legs. In the grand library the companions come across the main conspirator responsible for killing this realm’s creator Sonnorae. The Tyrant is an enormous blue dragon who deems himself the reincarnation of Kazavon, going by the name of the Great Kah Zavon instead. Scenery and miniatures are from Dwarven Forge, Thomarillion, Heroclix, Reaper Pathfinder Battles and Warhammer. If you want to find out how the encounter went, you can go to the campaign journal section of Paizo’s messageboards and look for MrVergee’s Curse of the Crimson Throne.
