The Great Empire is located in the southeastern starfield of the Orion Arm. It is said that hundreds of thousands of years ago, a powerful divine spirit-like creature appeared in this region, and since then, this starry sky has maintained advancement and development. By today, aside from the Great Empire, three of the top five civilizations within the Orion Arm are situated here.
However, this starry sky, which originally seemed like a holy land, was invaded by enemies. These enemies have caused massive destruction and massacre in this region of civilization development, leading vast amounts of ancient-feeling planets to become ruins.
Surprisingly, the main species of the Great Empire is very similar to Earth people; some Imperial persons, upon arriving on Earth, go unnoticed as aliens.
