Story
Master Chief was trained by The Chaturn Empire, however he failed his tests and was sentenced to be executed. He escaped his execution and became a fugitive, because of which he was pursued across the solar system by the Empire. As a result of being pursued, he joined the rebel group Covenant, which included two humans, one alien and one robot.

Later he was approached by Jar Jar Binks of The Second Empire of Dougtopia and offered money in exchange for his help in getting the Halo Ring. Master Chief knew that they weren't interested in helping mankind, but didn't care, as he needed money to save his girlfriend's life. As a result of negotiations via a chess game, Master Chief was appointed new Emperor and given a check for 1 trillion dollars

As an Emperor, Master Chief decided to establish a base on the Halo Ring. The Chaturn Empire's fleet attempted to shoot down his space shuttle, but was unsuccessful. He found that there was nobody else on the Halo Ring and built a base.
