In standard year 3017, Earth's civilization was defeated by the Chamber of Commerce mercenary group under the Star Alliance. After that battle, the solar system disappeared.
More than a hundred years later, a scholar studying the Sombra Temple in the Star Alliance Science City accidentally fell into the space-time ring of the cosmic string in the temple. She returned to thousands of years ago and encountered a group of mysterious unknown creatures.
As the remnants of the Earth slowly integrated into the Star Alliance, they discovered that their home planet Earth once had an identical temple. As the investigation deepened, the Earth's remnants discovered that the war a hundred years ago did not seem to be as simple as a competition for resources as stated in official records. . .
A few years later, disputes surrounding the temple's secrets gradually surfaced, and then a bank robbery directly kicked off a new round of interstellar war.
