The Great Star Sphere is the only significant area of realspace which contains matter and energy. It is composed of concentric spherical collections of stars called spheres separated by large expanses of nothingness called Abyssal Gaps. Connecting them to their neighbors are highways of traversible stars stretched between them like chewing gum called Abyssal Bridges.

The Great Star Sphere is divided into exactly fifteen Major Spheres, each of which contain their own Minor Spheres which in turn hold distinct regions and landmarks.

Following is a list of all major spheres, sorted based on whether they are significantly colonized by some galactic power. Each sphere may have multiple names, the name listed will be the canonical name provided by the Abrixine Catalog Index.

There are eight spheres occupied by intelligent spacefaring civilizations:

• GSC A and GSC B, two relatively small major spheres controlled by the Galactic Sapients Coalition strongly connected by an unusually high number of Abyssal Bridges which facilitates easy travel between the two.
• Amanillion, the primary space of the Greater Human Cooperative and its vassals.
• ESA SKYBOUND A*, originally Wahrk Aviform Hegemony territory but currently majority controlled by the Enid's Cluster Triad
• ESA SKYBOUND B*, a formerly unexplored, relatively small major sphere currently being explored and settled by the Wahrk Aviform Hegemony
• NATAS-Enida-Imp Cluster, the Enid's Cluster Triad's sphere of origin.
• Asriphale, the Nusita Divine Commandment's sphere of origin.
• Perivaga, an extremely large sphere near the center of the galaxy which has the most Abyssal Bridges of all major spheres, bridging it to Amanillion, GSC A, and ESA SKYBOUND A*. It is currently a contested zone between the Greater Human Cooperative and the Wahrk Aviform Hegemony.

The remaining spheres have no known intelligent spacefaring life:

• XSS-8, XSS-3, XSS-13, XSS-14, and XSS-15 are all major spheres only accessible by first passing through one of the three Abyssal Bridges stemming to them out of the NATAS-Enida-Imp Cluster. As such, they have not been explored or charted except by the Enid's Cluster Triad which retains exclusive control over all spacelanes leading in and out.
• Inaga Zone 13, often shortened to “Inaga 13”, is a major sphere neighboring Asriphale.
• GCR-10, a small sphere of little note on the periphery of the galaxy.

Main Article: Factions

The galaxy is controlled by numerous civilizations, factions, alliences, and other groups of interest. Here is a brief list of the major galactic players, sorted by the general nature of their existence.

Following is a list of political entities and alliances which exist primarily as governances over their people.

• Greater Human Cooperative - A Human led and governed alliance which controls much of its major sphere, the GHC is composed of the New Human Alliance and its vassals:
  • The Birn Reconstruction - A civilization composed of four species, the Bhirni, Nixiti, Pothon, and Pihitil.
  • Hilix Confederate Stars - Formed from the union of the Zhyn and Renau species.
  • Fern Systems, Limited - A megacorporation borne from Pihitil enterprise which gained total autonomy before being subjugated into the GHC.
• Enid's Cluster Triad - An Imperial Hamarchy consisting of three spacefaring races from the same major sphere which, after decades of war, united under common ground in order to exert control over the rest of the galaxy. The three members are:
  • The Askraadi Dominion - The current hegemonic leaders of the triad.
  • Hian Hegemonic States - Multiple distinct and non-homogenous Hii cultures which present to the Triad as the HHS.
  • The Mmnique Kingdom - Formed of two codependent species, the Iuspex and Ruspex.
• Whark Aviform Hegemony - A somewhat warlike coalition of avian species known for their generally honorable attitude. There are hundreds of individual political entities making up the hegemony, but the most powerful are:
  • Cheri-Nusit
  • Ilpixis
  • Aprexus-Pix
  • Astraxi Dominion
• Galactic Sapients Coalition - A highly populated direct democracy founded from the splintered remnants of pre-unification-war Human governments.
• Nusita Divine Commandment - A generally isolationist and violently religious cell of Nusti which gained intergalactic fame for cracking their species' homeworld after deeming the Cheri-Nusit pact heretical.
• Rinnegatamatha Hoard - A unified multi-monarchy of colossal dragon-like beings which can survive in most planetary conditions as well as the void of space.

The abundance provided by the galactic scale allowed for corporations, previously shackled by their planetary vessels, to expand into their own self-governing entities that other nations had to recognize and negotiate with in order to coexist. Sovereign Enterprise, also known as mega or gigacorporations, often (but not always) have territory overlapping with those of other powers, but also have their own laws and governmental systems which affect those in their employ.
