Transitive Planes

**Transitive Planes** is a collective term used to describe those planes of existence that connected other planes together, or could be used as a means of travel between points on a single plane. The various cosmology models each described them differently and ascribed them slightly different traits, but all were accessed by either magic spells, spell-like abilities, or portals. The known Transitive Planes were:

* The Astral Plane, which later became the Astral Sea
* The Ethereal Plane, which was destroyed by the Spellplague
* The Plane of Shadow, which later became the Shadowfell
* The Spirit World, which only connected to Kara-Tur
* The Plane of Mirrors, which connected to the back of reflective surfaces

Each had their own unique structure and means of travel, and each connected a different set of planes together.
