Infinite War
From Supreme Commander Wiki
The main conflict between the United Earth Federation, the Aeon Illuminate, and the Cybran Nation of Supreme Commander, the Infinite War has been waged for over one millenia. It followed the collapse of the Earth Empire after the separation of the symbionts from Earth Command, resulting in the formation of the Cybran Nation, and the formation of the Aeon Illuminate, after the death of the Seraphim on Seraphim II. The Infinite War is fought uniquely using giant Mech like Armored Command Units, operated by a single highly motivated pilot, that build factories, which in turn create fully robotic engineers and combat units along whith those they do all three faction do build superior manned units to there robotic counterparts. The Infinite War takes place on various planets in the Milky Way Galaxy. Quantum Gate Networks allow for instantaneous travel between the planets. The Infinite War has claimed billions of lives and has turned planets into nothing more than dead rocks floating in space.
The Infinite War came abruptly to an end by the unforseeable emergence of a Seraphim invasion force through a Quantum Rift above the planet Earth formed by Black Sun's firing. However, this only marked the beginning of another, even bloodier conflict. This event forced the Cybrans, Aeon, and UEF to forge a hasty alliance against the invaders. However, Brackman's computer, QAI, made with Seraphim technology, rebels and joins the Seraphim, along with a large part of the Aeon Illuminate which renames itself the Order of the Illuminate. This time though, one side is actually winning - unfortunately for humanity, it's the Seraphim and their allies. The Seraphim warriors are finally stopped when the inter-dimensional arch is destroyed, halting future Seraphim reinforcements. After this, they and their Order compatriots are hunted down.
