Between dimensions lies Ultra Space, a realm of crystalline meteoroids inhabited by the Cosmog line and reachable through Ultra Wormholes. Colored passages called Warp Holes tie it to numerous worlds, among them the world of Pokémon and the home dimensions of the Ultra Beasts; while wormholes can form naturally, they are usually opened deliberately by Cosmog, Solgaleo, Lunala, or Necrozma. The Aether Foundation's Professor Mohn discovered and named the realm, and Professor Burnet continues studying it.
