In a new plane...
This is the plane you came from. Inhabited by humans. A year ago it started falling apart from too many changes between there and Celestia.
The Outlands repairs it’s self slowly while you have taken refuge in Celestia. Unlike Celestia the Outlands is vast. There is the planet you come from in a solar system in a galaxy among other galaxies. There is so much mass in the Outlands that time goes very fast compared to the other planes.
