A Shade Realm or Vada is an Umbral realm dominated by a single Sphere of magic. Each Shade Realm is linked to the Shard Realm of one of the nine planets in the solar system, but manifest within Earth's Horizon--like a shadow cast on the ground by a passing cloud. Some of the more accessible Shade Realms have been colonized by mages; the great Hermetic chantry of Doissetep was transferred to the Shade Realm of Forces, for instance, to protect it from the Technocracy. Minor realms may be connected to a given Shade Realm, much as satellites may orbit a planet.
