When succeeding, Leo is requested to work for the Space Force to protect the colony from a terrorist attack. On his way to the Space Force, Leo rescues several civilians and often talks with Jehuty's artificial intelligence, A.D.A., regarding the value of life. Leo is hired by the Space Force to deliver Jehuty back to their ship. One of the few survivors, Leo Stenbuck, finds Jehuty and uses it to stop the Bahram soldiers. In the first game, Bahram forces attack Jupiter's colony Antilia to secure the two Frames, killing several civilians in the process. The story usually revolves around two specific Orbital Frames: Jehuty and Anubis created as the two "keys" of a superweapon called Aumaan. Throughout the Zone of the Enders series, a number of themes and dramatic devices show up prominently. These Orbital Frames come to shape the destiny of Earth and its colonies, for both good and evil. A new weapon given to these rebels is the Orbital Frame, a mecha which makes extensive use of Metatron-based technology. Eventually, different groups on Mars begin to rise up in opposition to Earth, the most well known of these called Bahram. Those in power on Earth begin to take a dim view of the colonists of Mars and Jupiter, calling them "Enders", and imposing harsh and exploitative laws and taxes against them. Fueling this expansion are two scientific advances: the development of the Laborious Extra-Orbital Vehicle, or LEV, a mecha used for labor and military use, and the discovery of Metatron, a high-energy ore found on Callisto. Mankind has colonized Mars, and space colonies are set up in orbit around Jupiter.
