Does the setting need a random generic human space empire? As a community member, I'm concerned that this sort of thing might "unbalance the setting or overshadow the played factions" — which is something our faction page's guidelines advises against — due to it being created with a population of 5 billion with a bunch of constituent worlds. Additionally, a lot of its description has real world comparisons and references rather than original ideas, which seems kind of lazy. If it's meant to be an offshoot subset of the civilization that is stuck in the SARPiverse, then maybe write it from the perspective of where they are in this universe rather than the parts we'll never see. From what I understand, it's based out of a small fleet, so there's no need to talk about 5 billion citizens in the infobox or talk about their government in another galaxy. Who governs the fleet? What's this fleet's culture and population? Stuff like that seems more relevant because it doesn't circumvent the faction buildup guidelines.
