In the Heart the Land of the Wizard of Oz

From publisher blurb: In the Heart of Oz contains procedural Encounter, Terrain and Weather Engines for Wilderness Hex Crawling across the fairy-tale like land of Oz. There is also a procedural 'dungeon' to take on the Wicked Witch of the West in her Yellow Castle. ItHoOz uses a 'Hex Flower' mechanic to generate these setting features.
