Empyrean Colony

Empyrean Colony (ラピュタン コロニー; Laputan Colony). Real estate companies and government began to recruit space colonists to search for a place to develop a project called "Empyrean Colony", which consists on a floating city and would solve two main problems: the lack of living places and the overgrowing population. After investing great amounts of money, a planet was chosen to house this project, but after years of trials and errors, it barely did approve all the tests, discouraging everyone to continue researching.

It's known to house to circuits: the Dash Circuit in the Pawn League, and the Twist Circuit in the Queen Leag.

Ikran's F-Zero timeline
The process of intergalactic development has been constantly put on hold due to the onslaughts from Dark Million, and the colony's still struggling to sustain all forms of life. It didn't quite live up to its name as a place for paradise.

While it doesn't necessarily take place during the events of Maximum Velocity (2585), there was only one fic that started to branch from GP Legend, P.J., the Empyrean Colonist. In it, the colony was the home world of the alien named P.J., an extraterrestrial that owns the Groovy Taxi. He was hard on his luck as his planet got demolished when a train crashed into a megaplex and killed one female human, along with countless passengers, as an act of terrorism. Since then, relief is still being brought to the colony due to this crisis, and P.J. has been living in Rick's and Tinsel's apartment complex in Mute City ever since.
