Multiverse

The Multiverse is the collection of planes that make up the known universe outside of the Material Plane. Although the universe was created by the gods themselves, the multiverse technically did not come later until many years later when the planes were split from each other. The model of planes can also be called the Great Wheel.

The Material and Pseudomaterial Planes

 * The Material Plane - Called Jaed-Najar by its inhabitants. A land of mortals and kingdoms great and paltry.
 * The Feywild - An offshoot of the Material Plane, but lined with vibrance and growth. Everything there is dialed up tenfold.
 * The Shadowfell - An offshoot of the Material Plane, but lined with decay and darkness. Everything there is immensly subdued and undersaturated.
