Fiction:Jephi Confederation

Edonis is a small galaxy, roughly 30,000 parsecs in diameter and 40,000 parsecs thick with roughly 3,600 stars within it, most being located in the Core or within the two major arms, Edon and Edui. In it's short history of around 100,000 years (Earth time), only two major Space-Faring life forms have presented themselves: The Jephi and The Maxidoni, each separated into the two arms.

The Jephi home world is located near the far end of the Edon Arm, named Cazorus and The Maxidoni's is far closer to the Core, only about 2,000 parsecs away. It's name is Faru. The Galactic Core of Edonis is a large red blob of collected stars, with high gravitational pull. Said pull has prevented Maxidoni ships from exploring the galaxy, as they eventually get sucked into the Core and destroyed, but they have expanded into the rest of their arm reasonably well, controlling around 1,450 stars. Meanwhile in Edon, Jephi technology has provided them with advanced ships capable of outrunning the pull, thus allowing them to make first contact with the Maxidoni on planet Angora. The Jephi control almost all of the galaxy, with 2150 stars in their domain.
