This appendix provides an overview of the multiverse, the overarching reality that encompasses D&D's countless worlds and adventures. These realms are explored in greater detail in the Dungeon Master's Guide, along with other planes like the Far Realm, Negative Plane, and Positive Plane.

The Material Realms

The philosophical and elemental forces of reality converge to create the following planes of existence:

• Material Plane. Most D&D adventures take place on the Material Plane, which holds the worlds of settings like Dragonlance, Eberron, the Forgotten Realms, and Greyhawk. There's also room for any world your group creates. Magic and physical laws shape this plane's diverse worlds.
• Feywild. This vibrant, idealized realm brims with life and emotion, which are most intense in the realm’s Domains of Delight.
• Shadowfell. This gloom-haunted realm holds grim wastelands, haunted ruins, and the infamous Domains of Dread.

Transitive Planes

The transitive planes serve as paths between planes:

• Astral Plane. This endless, silvery expanse links the Material Plane and the Outer Planes. Whole civilizations have arisen in this glimmering vastness, while others navigate the magical cosmos in spelljamming vessels.
• Ethereal Plane. This ghostly realm connects the Material Plane and the Inner Planes. The region where the Ethereal Plane overlaps with other planes is called the Border Ethereal, a place where creatures can glimpse visions of planes beyond.

The Inner Planes

Elemental forces and the building blocks of reality originate from these Inner Planes:

• Elemental Plane of Air. Winds blow clouds and floating islands across this boundless sky.
• Elemental Plane of Earth. This maze of caverns winds through stone and untold mineral riches.
• Elemental Plane of Fire. An everlasting inferno, this realm blazes with life on volcanic islands.
• Elemental Plane of Water. This bottomless ocean churns with mysterious sea life.
• Elemental Chaos. Here on the fringes of the Inner Planes, elemental forces clash unpredictably.
• Para-Elemental Planes. In these borderlands between the Elemental Planes, elemental forces combine into realms of ash, ice, magma, and ooze.

The Outer Planes

Realms where ideas take form and spirits spend their afterlives, the Outer Planes are the homes of immortals. The following locations compose the Outer Planes:
