Lore: The Usurpations built an energy factory, that transmits light and converts it into pure energy by pumping the energy through pipes which saves
more energy and power up the Usurpation Civilization. As the lights get converted into pure energy and get pumped into the middle platform, there are 2 magnetic fields set up, that actually are connected to each other. The force of the energy then collapse in itself so, so that antimatter is getting produced in the center. This makes it a infinite energy source. The Factory was using ALOT of other usurpations in their Civilization. Against the will clean the pipes, use ropes to attach certain platforms and so on.
However, there were alot of aliens that got mad about the faction and the way they got treated, they said: We are getting used for your power and for your factions. We cant allow this, we cant allow the harming you did on our creatures. we are getting used unfairly and for no other reason than this, we will declare a war to stop this once and for all.
