The Planar Universe

Beyond Terr'ahna lie several distinct planes. There are the elemental planes, such as the Abyss and the Divine. There is the Undergrave, or hell itself. Even the Dream Lands, the Dream Scape and Nightmare Realm, and the plane in between the Dream Lands and Terr'ahna, the Awakening. But flowing through and between all planes, including Terr'ahna, is a river of pure magical energy, of pure Mystia, known as the Flow, which acts both as a lifegiving artery between each of the planes, and as a barrier, keeping each of the planes from crashing into one another. Without the Flow, this universe simple could not exist.

No one has ever truly been able to map the universe, it's simply not possible to do so. This map is merely a representation of what it might look like, and where the distinct planes might be in the Planar Universe in relation to Terr'ahna, also known as the Material Plane or Physical Plane.
