Serus

Serus was once a major Omni star system. As a result, many ruins are scattered across and has become the target for many looters. A Dyson Sphere was built around Serus making the system appear like a large red square when viewed from several lightyears away.

Enkladius
Enkladius is a heat blasted Earth-sized planet that only takes three days to orbit. As a result, it has dreadful surface temperatures of over 2,200 F, and the planet's surface is slowly melting away into lava.

Dianis
Dianis is a planet that likely had vast oceans during the time of the Omni. However, these oceans have long since boiled away, leaving behind a geography of giant salt flats and large mountain ranges. Surprisingly, the planet still has a temperate environment, though the planet's thick atmosphere of carbon dioxide and nitrogen makes it unbreathable.

Libitinia
Libitania is a junkyard world whose atmosphere and geography was shaped by the Omni that stored retired starships and other vehicles here. It is hypothesized to be one of the earliest established colonies of the Omni because the amount of debris manages to cover the entire planet. Remarkably, these ships have become well preserved.

Zirin
Zirin is a large terrestrial planet dotted with mining facilities. It is very rocky and sustains an atmosphere of kryton and argon.

Arolaus
Arolaus is a gas giant 13 Jupiter masses large. Though it outputs lethal radiation, evidence of former helium-3 mining is found within the moons.

Sallas
Sallas is a typical hydrogen helium gas giant.
