The Homeworldian Empire was the galaxy spanning militaristic regime of Homeworld. It ruled over 10 Quadrants and frequently destroyed planets or suns to gain resources. Opposed only by the 5th and 7th Quadrants, it would last a hundred-thousand years and rule through fear and subjugation.
It was unofficially governed by The Intergalactic Police Force through a treaty made in 23002.
