Reagan was a supercarrier.
At Doran Routhe's private laboratories on Earth, Reagan was loaded with thousands of United Powers League prisoners and enough supplies, rations and hardware to aid them once they arrived at their destination.
Reagan was programmed to follow Nagglfar as it was launched toward Gantris VI. At some point during the voyage Reagan veered off course along with the other supercarriers and barrel blindly through warp space for twenty-eight years until its warp-drive engines reached critical meltdown.
Reagan emerged into real space in the Koprulu sector. With its engines destroyed and its life-support batteries nearly exhausted, Reagan engaged its emergency protocols and landed on Umoja. The 'cold sleep' chambers were then deactivated and the passengers slowly awakened. In an attempt to find refuge in their new surroundings, they stripped Reagan of essential materials. In its vaults, works of literature such as the writing titled The Book of Virtues were discovered.
"Reagan" is a league name in StarCraft II.
