Heavenly Warriors: The interstellar Era

" It was in final years of the 21st century that the first successful matter/antimatter reactor was built. This reactor was the size of a small town, and only produced enough energy to be useful for research purposes. However, this breakthrough was the first herald of a new age of innovation. Over the next five decades, the technology behind the matter/antimatter reactor was refined and perfected, each iteration becoming more and more efficient. Research colonies on Earth's moon and Mars were built to house more powerful reactors.

In the meantime, humanity's colonization of the Earth's orbit continued at a slow, but steady pace. Small, but permanent orbital colonies were established, as was Olympus City on Mars, the first permanent settlement on another world.
