The year is 2307 A.D. Although fossil fuels have been depleted, humanity has obtained a new source of energy to replace them in the form of a large-scale solar power generation system based on three huge orbital elevators. However, the benefits of this system are available only to a handful of major powers and their allies. 
The three orbital elevators belong to three superpower blocs. These are the Union, led by the United States of America; the Human Reform League, led by China, Russia, and India; and the AEU, led by Europe. These superpower blocs continue to play a grand zero-sum game for the sake of their own prestige and prosperity. 
In this world of never-ending conflict, a private armed organization appears, dedicated to the elimination of war through armed force. Its name is Celestial Being, and it is in possession of "Gundam" mobile suits. With these Gundams, it begins armed intervention into all acts of war.

It is the year A.D. 2307. Fossil fuels on Earth have been depleted entirely, with mankind turning to the next available power source: solar energy. During this time, 3 orbital elevators with solar power generation systems are built, each under control by the Union (formerly United States of America), the Human Reformist Alliance (Russia, China and India) and the AEU (Europe). However, not all countries are able to enjoy the benefits of this system, leading to widespread resentment and war. Arising out of the conflict, a mysterious non-profit military organization known as Celestial Being appears, dedicated to end all warfare using Mobile Suits called Gundam. This begins the stories of Gundam Meisters (pilots) Setsuna F. Seiei, Lockon Stratos, Allelujah Haptism and Tieria Erde as they are thrown into conflict between the 3 superpowers and the other various factions.
