Welp, I said huge, and FUCKHUEG is what I went for.

The large blue sphere with the hazard line box is earth.

Blue circles are 'Populi' worlds, planets that were 'glassed' from orbit to clear indigenous life to make way for enormous hab-complexes to stash lots and lots of people. The Terrans get most of their recruits from these worlds.

Green circles are 'Agri' worlds, worlds designed entirely for farming, so that they may provide the fucktons of food this empire requires.

Black and dark yellow boxes are mining worlds, ones that 'core' various rocks out for valuable materials, and double as industrial centers. Many worlds in many systems have been utterly destroyed, and many of these are actually in asteroid fields. Almost all imperial systems have some sort of industrial/mining operation, but the marked ones are the extremely important ones.

While enormous, the Terran empire is spread extremely thin, and can only bring but fraction of its might to bear upon any foe, thus their original plan of rapid expansion has slowed down and is now focused almost entirely on securing current lands. Most of their armed forces are also currently employed on the internal zones as 'peacekeepers.'
