Once the worlds were sealed off 5 years ago, heartless and nobody ships had completely disappeared from space, as well as any gummi ships. It is said that many years ago gummi ships were mainly used for space battles, but after years of battling, gummis were soon seen as only a means of transportation. Most areas in space have some kind of ruins laying around, but they can be easily avoided through alternative routes.
It has only been recently that the worlds have been connected again. Routes have been reopened for flight, but it seems like the heartless and nobody ships have already taken over the skies. There have been sightings of swarms of heartless ship roaming space, and in even larger numbers than usual.
