Likewise, each level of a regio is a different supernatural dimension, but all coexist in the same mundane location. The illustration demonstrates this pictorially. There's nothing to distinguish regiones from other auras, until one realizes that varying levels of reality exist on the same spot. A regio level that is more attuned to its realm has a higher aura rating, and so looks different from the rest. Lower levels appear only slightly changed from the mundane world, while higher levels tend to acquire many of the characteristics of their native realms.
Regiones have inhabitants, just like other areas of supernatural aura.
These beings tend to cluster on specific levels, though they can cross level boundaries freely. The higher one travels in the regio, the stranger and more supernaturally aligned its inhabitants become. When physically crossing the boundary of a regio, travelers disappear from the ordinary world and enter supernatural realms. Any being directly connected to the realm associated with a regio can automatically lead up to a dozen mortals or magi into that regio. Faeries can lead mortals into faerie regiones, angels and people with True Faith can lead people into divine regiones, demons and people who have sold their souls can lead people into infernal regiones, and magical beasts can lead mortals into magic regiones.
