Tremanre:

Orbital Distance: N/A AU
Orbital Period: 1.0 Earth-years
Keplerian Ratio: N/A
Radius: 1,528 km
Day Length: 1.0 Earth-years
Atmospheric Pressure: 0.00 atm
Surface Temp: 55 °C
Surface Gravity: 0.1 g
Mass: 0.006 Earth-masses

Tremanre is a dwarf planet composed of light magnesium silicates, with deposits of aluminum. Its surface is covered by wide swathes of ancient, dark basaltic lava, possibly indicating the world was created through an impact with some other body in the system.

Tremanre’s magnetic field is nonexistent. This makes it impossible for ships to dump their drive core charge from orbit. That said, Tremanre’s minuscule gravity allows even cruiser-sized vessels to land safely for direct grounding.

Edolus:

Orbital Distance: N/A AU
Orbital Period: 2.7 Earth-years
Keplerian Ratio: N/A
Radius: 5,729 km
Day Length: 50.3 Earth-hours
Atmospheric Pressure: 0.8 atm
Surface Temp: −1 °C
Surface Gravity: 0.87 g
Mass: 0.697 Earth-masses

Edolus is a terrestrial planet with an atmosphere of carbon dioxide and nitrogen. Edolus’ surface is covered by wide deserts of silicate sand, with only a few areas of igneous rock highlands to break the abrasive, dust-choked wind.

Edolus’ orbit is congested with debris thrown inwards by the gravity of the gas giant Ontamalca. Due to a high rate of meteor impacts, exploration is highly dangerous.

Altaaya:

Orbital Distance: N/A AU
Orbital Period: 18.1 Earth-years
Keplerian Ratio: N/A
Radius: 11,190 km
Day Length: 47.2 Earth-hours
Atmospheric Pressure: 0.20 atm
Surface Temp: −136 °C
Surface Gravity: 1.7 g
Mass: 5.194 Earth-masses

Altaaya is an unusually large terrestrial world with a trace atmosphere of methane and ammonia. The surface is frozen, and mainly composed of sandstone and other sedimentary rocks with deposits of iron and chlorides. Judging by the sedimentary composition of the crust, it appears that Altaaya once possessed an atmosphere thick enough to support some form of liquid. What cataclysm stripped the atmosphere and left the planet to freeze is not currently known.

Ontamalca:

Orbital Distance: N/A AU
Orbital Period: 39.1 Earth-years
Keplerian Ratio: N/A
Radius: 72,492 km
Day Length: 17.7 Earth-hours
Atmospheric Pressure: N/A atm
Surface Temp: N/A °C
Surface Gravity: N/A g
Mass: N/A Earth-masses
Satellites: hundreds

Ontamalca is a large hydrogen-helium gas giant with traces of chlorine and sulphur in the atmosphere. Its massive gravity well tugs many asteroids from the outer belt inwards, past the orbit of Altaaya and Edolus and eventually settle into the inner belt.

Ontamalca’s orbit is congested with hundreds of captured moons. Most last only a few thousand years before being ejected, dragged down into the atmosphere, or ripped apart by tidal forces and added to the gas giant’s immense rings. Attempting to navigate this chaotic environment is hazardous at best. Ships without military grade kinetic barriers are likely to suffer catastrophic impacts.

Alsages:

Orbital Distance: N/A AU
Orbital Period: 73.8 Earth-years
Keplerian Ratio: N/A
Radius: 4,926 km
Day Length: 23.3 Earth-hours
Atmospheric Pressure: 0.00 atm
Surface Temp: -193 °C
Surface Gravity: 0.7 g
Mass: 0.414 Earth-masses

Small, distant Alsages is a small terrestrial, with a trace atmosphere of methane and argon. The surface is composed of water ice and calcium with occasional deposits of light metals.

During the Alliance’s pirate suppression campaign in the 2160’s, the batarian Eluam Ran’perah was caught with his frigate Tunerron grounded on Alsages for drive discharge. When challenged by the cruiser Hyderabad, Ran’perah refused to surrender. The Tunerron was destroyed attempting to take off. The debris is strewn across the southern hemisphere.
