Good plane names, in the D&D sense of planes of existence rather than aeroplanes, describe what the place is made of or what it's for: The Brine Ocean for an elemental plane, The Ivory Terraces for a heaven, The Tiers of Sealed Fates for a hell. This plane name generator names D&D planes of existence and other dimensions: elemental planes, heavens, hells, fey and shadow realms, astral and dream planes, and planes of pure chaos, with a short description if you want one.
Eight good plane names
All eight came from the generator, across its six styles:
- Caldira, Plane of Boiling Seas: an elemental plane with a name and a title, so players can say either.
- The Twelve Floating Mountains: an earth and air plane described in four words.
- The Ivory Terraces, where the souls of the good rest in endless gardens: a heaven built in levels, which gives the party somewhere to climb.
- The Tiers of the Tally, where the air smells of sulphur and old parchment: a hell run on paperwork.
- The Glimmering Courts, where travellers who eat the food can never leave: a fey plane with the oldest fairy rule of all.
- Palehollow, a grey echo of the world where colours drain away and sounds grow faint: a shadow plane in a single word.
- The Drift of Waking Dreams, a starry void crossed by ships with silver sails: an astral plane for travelling through.
- Skrelurra, where gravity is a suggestion rather than a rule: a chaos plane with harsh sounds to match.
Planes in D&D and before it
The idea of an astral plane is older than the game. It came from 19th-century occultism and Theosophy, which described layers of existence beyond the physical world. D&D took the word and built a whole cosmology on it.
- The Inner Planes are the elements: fire, water, air and earth, and the places where they meet.
- The Outer Planes are the realms of gods and the afterlife, from the heavens to the hells. Earlier editions arranged them in a ring known as the Great Wheel.
- The Feywild and the Shadowfell are the 5th edition's echoes of the mortal world: one brighter and wilder, the other grey and drained of life.
- The Astral Plane is the silvery space between them, crossed by travellers and their ships.
The generator follows the same divisions, so its names slot into a D&D cosmology or your own. Choose With a description for a line about what's there.
Building your own cosmology
- Name planes after what they're made of or who lives there. Players remember "the hell of contracts" better than an invented word.
- Use a short name and a long one: Caldira in conversation, Plane of Boiling Seas on the map.
- Give each plane one rule that makes it different, like not eating the food, or gravity that changes.
For the hells in more detail, try the Demon Realm Name Generator, and for the powers who rule the planes, the God Name Generator. For the world they all surround, there's the World Name Generator.
