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. They arrive in an overgrown forest, where they meet a gnome who looks just like the figure on the ‘Hidden Truth’ card. The sky is a featureless dome painted in a fainted blue hue, while a stylized representation of the sun is held aloft by a large mechanical arm. Can the confused little scholar tell the heroes where they are? You can read all about it in the campaign journal section of Paizo's messageboards under MrVergee's Curse of the Crimson Throne. Miniatures are by Pathfinder Battles, Reaper and Warhammer.
