==Stars==
===Crab Pulsar===
The Crab Pulsar is a young neutron star at the center of the nebula. It is roughly 20 km in diameter, and its pulsating beams rotate 30 times per second.
===Wollstonecraft===
Wollstonecraft is classified as part of the territory of the Delson Hegemony. After the War on Gaea, the system was given to human refugees from the war to start a new life of their own. They renamed all of the planets and moons in the system after characters from Mary Shelley's novel Frankenstein.
===Sarkanna===
Sarkanna is home to one of the oldest habitable planets known in the galaxy: Zema. The star system was believed to have once been home to ancient civilization that inhabited the galaxy four billion years ago. Physical evidence from this previous civilization is nearly non-existent, and the system's previous inhabitation was only known through data records found on Novarckas.
===Stratus Centauri===
Stratus Centauri was a system previously colonized by the Omni. Their ruins gave rise to a spacefaring civilization known as the Sarkakion.
