Mastaar Galaxy

"Pale white mist and mysteries in every star, this is the Mastaar Galaxy, our beautiful home afar"
-Tzan'Kai the explorer
The Mastaar Galaxy, also known as the Milky Way, the Silver Sea, and Abraxas's Devour (after my beloved!), is a large spiral galaxy located in the Virgo Supercluster. The galaxy orbits around a large black hole known as to terrans as Sagittarius A, and to non-terrans as the Great Eye. It is home to billions upon billions of lifeforms. 
The galaxy is subdivided into regions and sectors, with the Great Eye making up the 0,0 point. The galaxy has no single unified government, instead being divided among intergalactic nations. The galactic south is dominated by the rival Aravaraia and Harva Empires, which have been at war since the Raia Occupation of Harvath 4 thousand years ago. It also contains the Free World of Quainaar, and the Gordau Empire, which has been eating away at both the Raia and Harva Empires. 
The galactic north is connected to the south through only the Damvarati Gap in the west, and the Da'atashi'i Trade Worlds in the East. It contains a multitude of smaller nations, like the Association of Worlds, the Naas Sector, and the Rotechnica Black. 
There is also the Galactic West and the Galactic East, both of which consist of undiscovered space. The eastern one is known as The Sclera, while the western one is called the Scotoma. The only confirmed nation to exist in either region is the Federation of the Sol Stars. 
The Mastaar Galaxy is home to a mysterious substance known as magic or praxis. About 9% of the entire galactic supply is located in the Sol System with 8% on the world of Earth, primarily because of the replenishing effect caused by the Convergence, known to Mastaerians as the Illumination. Large beings known as the heaven sailors can sense and follow this magic. 
The Mastaar Galaxy is currently set to form a galactic binary with the nearby Andromeda Galaxy, known to non-Terran Masterians as the Cradle of Arcturian (yes, that's me). The galaxy can be seen from the naked eye, and fills up a good portion of the sky in The Scotoma. Alongside it, a smaller satellite galaxy known as Triangulum/The Kassandric Eye also orbits Mastaar. Exploration missions to both are considered a top priority among Mastaerian explorers, such as Tzan'kai.
