It's 2217, and humanity is mostly governed by the solar system-wide government called the Sol Governance. Suddenly, as if from nowhere, the crew from several governance military stations is abducted by the arrival of a group of lights from outside the Sol system! Eventually, the governance operation against "the visitors," led by Admiral Reshma Shan, is forced to work with a two-hundred-year-old political enemy of planet Erth: the descendants of the lunar society of Tellmondo, the Asteropians!
