List of Spelljammer crystal spheres

The following fictional solar systems were created for Spelljammer (1989), a campaign setting for the Dungeons & Dragons role-playing game. Each system contains a celestial body whereupon one of three previously-existing campaign settings was located; the other celestial objects were created to flesh out the system, and link it to the other two systems.

Each system is listed from innermost body to outermost. Unless otherwise noted, all planets are spherical, with breathable air.

Krynnspace

 * Sun: Star and central body.
 * Sirion: Molten lava planet with a few solid rock plates. Home to various fire elementals.
 * Reorx: Mountainous terrestrial planet, inhabited primarily by dwarves. Has one moon, Ora.
 * Krynn: Terrestrial planet with three moons: Nuitari, Lunitari, and Solitari. Home to the Dragonlance campaign setting.
 * Chislev: Terrestrial planet. Stormwracked jungle from pole to pole. Home to barbarians of various PC races.
 * Zivilyn: Gas giant with twelve moons. Inhabited primarily by avian lifeforms.

Greyspace

 * Oerth: Terrestrial planet and home to the Greyhawk campaign setting. (This solar system is geocentric, not heliocentric.)
 * Kule: Tidally-locked terrestrial body. Covered with the ruins of a humanoid civilization, but lacking any air whatsoever. A magical cataclysm is suspected to have caused the depopulation.
 * Raenei: Terrestial planet, covered with earthlike features, including animals and monsters, but no sentient life.
 * Liga, the Sun: Star. Has many small lakes of elemental water to keep it from burning too hot. Larger than Oerth, but orbits it anyway.
 * The Grinder: Asteroid belt.
 * Edill: Gas giant, populated primarily by dragons.
 * Gnibile: Dark-red gas giant, with blobs of lava and shards of ice in the interior. Contains a gate to the Negative Material Plane. Populated primarily by undead.
 * Conatha: Elliptical water world with two solid cores that orbit around each other. Populated by many piscine creatures, including merfolk and sahuagin.
 * Ginsel: Crescent-shaped world that resembles an apple with a giant bite taken out of it. Has an atmosphere on the inside of the crescent. Basic civilized fantasy world.
 * Borka: Spherical asteroid cluster with a common atmosphere. Formerly a planet inhabited by orcs, goblins and other humanoids, it was devastated by the magic of the elves.
 * Greela: Another spherical asteroid cluster with a common atmosphere, although many of the asteroids bear huge forests. Home to the elves.
 * The Spectre: A flat, circular disc of rock that appears to vanish and re-appear as it is seen edgewise, then rotates to show its full face. Also called The Wink. Has an atmosphere and water, but no life.

Realmspace

 * The Sun: Star.
 * Anadia: Terrestrial planet, largely badlands. Run by civilized halflings that keep the barbaric humans on reservations for their own protection.
 * Coliar: Gas giant with many earth and water islands on the interior, populated primarily by lizard men, aaracokra and dragons.
 * Toril: Terrestrial body home to the Forgotten Realms campaign setting. Has one moon, Selune.
 * Karpri: Water planet with two icecaps and an impenetrable equatorial seaweed jungle. Populated by primitive nomads.
 * Chandos: Another water planet with thousands of asteroids floating underneath the surface. Also populated by primitive nomads
 * Glyth: Terrestrial planet, once-Earthlike with an advanced civilization, now with a foul atmosphere. The remaining humans are hunted by the planet's subterranean rulers, the mind-flayers.
 * Garden: Spherical cluster of asteroids linked by a common atmosphere and the roots of a single enormous plant.
 * H'Catha: Flat, circular disk of water. Populated by beholders.
