A long time ago, 65 Million Years to be exact, in the Galaxy. Life existed on many planets across the Galaxy While on some planets it was very at very primitive stage, while on some other there thrived intelligent lifeforms which grew their technology to large extent. Primia was one among those planets. Primians were a highly advanced race of beings . Their civilizations were fueled by Energon, the purest form of energy harvested along with a metal called Cytium from a Star using Star Harvesters. They were divided in the war between the Priman republic and the Rexen empire.

Rexens were originally a colony established on habitable planet, they named Quintessa. As the time passed, the colony grew and scattered across the planet. The growing colony was initially under Priman rule, but ultimately, it evolved into an empire ruled by the Rexen dynasty. The Empire became part of the Alliance, a coalition of Space Empires and Republic across the Galaxy bounded by a common constitution. This constitution provided guidelines over certain aspects like Colonizing a new planet and interaction with its native lifeforms, interplanetary trades and exchange, peace across the Galaxy while each government had their own constitution and laws. Priman republic was most powerful and technologically advanced member and leader of Alliance. But as the Rex Tirus ascended the throne, he saw the destiny of Rexen empire to rule over the Galaxy. He enticed some members of Alliance with promise of power and rights which they couldn't get under Priman leadership. In return, they had to support and accepting Rexen empire as their leader. Thereby, he established the Imperial Command and started war against Alliance, especially the Priman republic.
