lore for Hegemony
Of course, not all colonists were so wicked. Some were able to band together – the Hegemony of today was the result of such an alliance, one of necessity between the military, farmers and workers. About three months after the Collapse, a Domain task force emerged from hyperspace in the sector. It was named Strike Force Pollux, and consisted of elements of the 14th Domain Naval Battle Group. The ships were running on full automation, as it was sent many years ago with the objective of studying the effect of long term cryo-sleep on human beings. Soldiers from the disgraced 200th Legion constituted the bulk of the test subjects. As the officers and crew of the task force were awakened, they quickly recognized the small colonial community was on the brink of collapse.
The task force could not be matched in battle in space or planetside, but they lacked crucial supplies. They sought to annex worlds that needed their protection, and that could also feed the tens of thousands of their soldiers and crew. The farmers of Verdaria II, and the men who maintained the works in an industrial autoworld of Hastaeus Prime were annexed first to secure basic provisions and repair facilities for the fleet. They were followed by the fledgling colony of Itos II, highly sought for the rare resources found there. These three core worlds and the men and women of the Domain task force were the foundation of the Hegemony.
so this is how i take this and i have made bold some of the things I want to reference within it.. first of which is the quality of the military that is the backbone of the Hegemony. the "disgraced" 200th Legion. to me this sounds like an arm of the military that was formed to toss the trouble makers in deemed valuable enough to keep around but not so valuable that you want them influencing the rest of your armed forces.
next they sought to annex worlds so that they could eat. and maintain there fleet. but also note that it does not say they went out of there way to protect anyone else. this fleet from the old empire seemingly turns its back on any colony that can not pay. at least there is no evidence to suggest otherwise. and if your going to say they protected so and so over here and so and so over there. why not list all the rest with them. unless they decided not to.
the way i see it. the disgraced 200th legion saw this as an opportunity to do things there way. not the way of the government that they knew. but the way in which would reward them the most for the least amount of effort. and so became a mafia of sorts. creating there own government. but again going by what is said in the lore. I would imagine that if at any time one of those colonies currently under there protection lost the ability to pay/supply them they would hang them out to dry and move on. which in my book is a flaw so grievous that I cant think of them as a true government body.
Because I cant think of any government currently that would just cut pieces of itself out and give up sovereignty over. Any government I can think of instead works the other way they fight to gain land and then take more land from other governments usually threw war never to give up any land they claimed.
at least thats my 2 cents on how i precieve the Hegemony to work.
