Regio
Synopsis
A regio (pl. regiones) is an area or region where special properties of one of the Realms of Power manifest. Regiones consist of multiple aura levels, the weakest being connected to the outside world, and the strongest in the (not necessarily geographical) center of the regio.
Effects
Like auras, regiones effect the exertion and manifestation of mythical powers depending on whether the exerting creature or effect is aligned with the same Realm as the regio it is evoked in.
