The upper planes (sometimes Upper Planes) is a collective term used in the Great Wheel cosmology model to represent the Outer planes of Good alignment, located across the top of the Great Wheel. These are Arcadia, the Seven Heavens, the Twin Paradises, Elysium, Happy Hunting Grounds/Beastlands, Olympus/Arvandor, and Gladsheim. The World Tree cosmology model rearranged, renamed, and reorganized the upper planes into the Celestial planes but some people still use the older term to describe the good-aligned planes.
