Astral Reaches

Although directionally when discussing Umbra is an exercise in futility, if we were to step and look at the universe from a four-dimensional perspective, then this may apply.
That said, if one were to go "up" from the Penumbra, one would reach the Astral Reaches, also called the Astral Plane, the Astral Umbra, the High Umbra, or the Upper Umbra. The Astral Reaches are the realms of thought, of idea, of concept. This is the Umbra most frequently traveled by mages.
The High Umbra or Astral Umbra is a place that can broadly be considered a reflection of the consciousness of the entirety of humanity. It can be divided into the Vulgate (a region where various common ideas (e.g. invention, love, or hand-to-hand combat) form small microcosmic realms that interact frequently with one another as human ideas and beliefs change), the Spires (a region where major abstract ideas such as War or Love form sizable realms), the Courts (where major societies such as the Mount Olympus of myth and the Court of the Hindu pantheon, gods included, can be found), and the Epiphanies (a realm of ultimate abstraction, unattainable by most mortals). According to the Wraith, while certain afterlives (such as realms that are apparently the Christian Heaven and Hell) seem to play themselves out here, they are not populated by the souls of the dead but instead by beings who exist as a fundamental part of the realm.
