Earth
Once the center of humanity in the Sol, Earth has now become a much different place. In the year 2022 an Astral Gate near the Moon malfunctioned and in the resulting explosion destroyed roughly a quarter of the Moon and sent debris raining down on Earth destroying the cities and landscape. In the years since the disaster most of the survivors have migrated from Earth, which still experiences daily showers of deadly meteors, outwards into the Sol. Those remaining tend to live in cities protected from the falling debris, clustering together to attempt to retain colonization of the home world.
