Known Universe

Known Universe, also called Known Space, sorted the Universe or the Civilization, is the universe that had already been explored and settled by humanity and allies during the Next Renaissance through different means. Like the name implied, it composes a vast number of galaxies, in which 4 main ones (see: the Core) being the central hub of virtually everything and the cradle of all intergalactic superstates. While the nearer to the Core a galaxy is will gain more profitable interest and wealth, the more distant it is, it'll be the opposite.

The Known Universe could be divided (not 100% clear, though) into 3 categories:
 * Core Systems: All 289 superstates and a major number of smaller planetary powers locate in this space. Including the Laniakea and its neighboring space, notably are Shapley, Hercules, Coma, Perseus-Pisces plus their surroundings, with the Laniakea being the centre. These are the most powerful, stable, freedom and prosperous of all. All the most elite administrative units of those superstates are here.
 * Inner Realm: also called Inner Sphere/Space/Rim. Spanning billion of light years, continuously from the Core to outerspace, encompassing an uncountable number of space objects, from space station to whole solar system. The vast majority of both population, influential subjects (independent stations, communities, planets....) and the rest of those superstates' sovereignty space locate around here. The society here, despite still enjoying tremendously benefits from the Core, is less stable & occasional being threaten by terrorists, mostly from the hardliners (remnants of Communist/Nationalist hardheaded Chinese & Russian, species dissatisfy with the current living.....)
 * Outer Realm: also called Outer Sphere or Rim. To put it short: the major environment here could be described as much similar to American Wide Wild West, Siberia region during 19th century or Australia/Brazil during past gold rushes. Despite all the efforts from both central, regional and local governments, the common theme here, fueled by past and present Gold-Rush-styled feverish migrations, is what you could see in Western-themed movies in early 20th century. The most lawless region of all, but also full of incredible chances, as vast number of planets here still under development or just being discovered/start to explore by the majority of the Civilization.
