Wildspace is a spelljammer-based setting. Planetary systems are encapsulated in enormous crystal spheres, floating in phlogiston. 

There are several major territories in Wildspace:
  * [[imperium|The (Lost) Imperium]] - the militant remnants of the formerly invincible Dwarven empire
  * The [[Triumphant Cycle]] - a strictly hierarchical Elvish monarchy
  * The [[Scro Emirates]] - a loose alliance of Orc nations
  * The [[Concordance]] - an oddly ethical necrocracy
  * [[Uropator]] - an Illithid hivemind
  * The [[Madworlds]] - an otherwise unclaimed space infested with beholders
  * The [[Skylands]] - a xixchil nature preserve
  * The [[Perfected Society]] - a racist and xenophobic gnome technocracy
  * The [[Free Trader's Guild]] Territories - a Neogi hunting ground
  * The [[Arcane Consortium]]

Several minor factions are also notable enough to be worth mentioning:
  * The [[Brightest Flame]] - an area full of fire elementals
  * The [[Dreamsphere]] - inhabited by aboleths, and contained jointly by the neogo and Uropator
  * The [[Twilight Ravening]] - a rapidly expanding kython brood which devastated the Dwarven empire
