The Draconus DictumMaterial Echoes
The Material Plane is a richly magical place, and its magical nature is reflected in the two planes that share its central place in the universe. The Feywild and the Shadowfell are parallel dimensions occupying the same cosmological space, so they are often called echo planes or mirror planes to the Material Plane.
The worlds and landscapes of these planes mirror the natural world of the Material Plane but reflect those features into different forms — more marvelous and magical in the Feywild, distorted and colorless in the Shadowfell. Where a volcano stands in the Material Plane, a mountain topped with skyscraper-sized crystals that glow with internal fire towers in the Feywild, and a jagged rock outcropping resembling a skull marks the spot on the Shadowfell.
