The Lyra Empire

After humanity mastered spatial jump technology, a new Age of Exploration began.

In 2126 AD, humanity on Earth began migrating on a massive scale, setting out for Green Sea, a planet 70,000 light-years away in the direction of the Lyra constellation.

That year was also known as the first year of the Galactic Calendar.

In Galactic Year 1037, an imperial exploration ship discovered alien life in the Red Wheel System and named these savage, vicious alien lifeforms the Zerg.
