Stormhenge

No one knows for sure when, and indeed, how, the ancient structure known as Stormhenge was created. Even the Orcs, prevalent throughout the Badlands, give these concentric henges a wide birth. It is thought by some that the pillars are part of a device that funnels the Winds of Magic, channelling them directly into one host, should they stand on the central column. However, this has never been confirmed, for those few Wizards who have been brave -- or foolish -- enough to stand upon the central pillar have never survived to recount their experience.
