rigors of space travel. However, after the Cam Ranh calamity, Tiphares lost communication with both the surface and its sister city Ketheres. Now, Tiphares is mainly a source of living human brains that are integrated into Ketheres' quantum computing network known as Melchizedek. The original name in Japan is Zalem. Ketheres is Tiphares' sister city in space, connected to each other through an inertially balanced orbital elevator. It is also connected to an orbital ring, which is balanced by a similar orbital elevator and space city on the opposite side. Ketheres is somewhat of a utopian human society. However, the peace that is enjoyed there is actually a result of a system of mind-controlling computer chip brain implants and a ubiquitous system known as Unanimous. In order to be granted citizenship in Ketheres, individuals must have these implants. The original name in Japan is Jeru. Leviathan I was once one of five interstellar colony ships, but is the only one remaining after the Cam Ranh calamity caused by Alita's past self Yoko. It's now docked in Earth's second Lagrange point, serving as a space colony. The central hub with artificial gravity houses a whole city and vast war game areas, where people made immortal by nanotechnology pay to fight for fun. Mars, the first planet to be colonized by Earth, is currently under a four-way civil war with almost every side secretly being backed by one of the major powers of the Solar System. Venus is being terraformed with the help of a gigantic mirror in orbit, blocking most of the sun and cooling the boiling surface. A number of orbital cities form the République Vénus (Venus Republic) and provide homes for a race of transhuman people with grotesque physiques and a liking of vile debauchery such as quasi-cannibalism. The author uses incorrect French to describe it, the correct form is République de Vénus. Jupiter is now almost completely covered by an incomplete Dyson Sphere. It is in this sphere where the Jovians, who have given up their human bodies in exchange for cyborg box-like bodies, now live. The materials needed for the completion of the sphere come from Saturn's moons and the asteroid belt — the same moons and asteroids where Venus gets materials for its own terraforming projects, which leads to tensions between Jupiter and Venus. is a term used to refer to humans who are infected with
