The Illal System:
The Illal solar system was first surveyed in the middle of the twenty second century, during a time now known as The Great Expansion, by the deep space exploration ship, SNARK.
This ship was built and funded by The Torkelik Foundation, a consortium of multiplanetary corporations.
The discovery of the rare mineral Caverite in the system, secured it a special and important place at the time.
The first people to settle on Illal, a then lush, sub tropical world, found that the atmosphere was un-breathable. As a result, three large atmosphere processing plants were set up on the surface to terraform it. These units were set up at the locations now marked by the Prosk, Sentium and Crion hubs. They also found some ancient ruins scattered around that date back thousands of years, some of which go deep into the planet. At the moment, no one knows who built them.
Below is a diagram of the Illal solar system with the relative sizes of the six planets.

We will start with Helos.
Helos

Closest planet to star
Size: Diam 12390km
Mass 0.92 Earths
Avg Temp 165 c
Orbital Year 105 days
Length of Day 1.29 days
Distance from star 65.3 million km
Helos is an arid hot world with active volcanoes and a toxic atmosphere. Several large deposits of Caverite can be found on this planet, but the harsh atmosphere makes it difficult and expensive to extract.
---------------------------------------------------------------------------------------------------------------------------------------------------
Illal

Second planet from star
Size: Diam 13158 km
Mass 1.08 Earths
Avg Temp 37.8c
Orbital Year 292 days
Length of day 22.5 hours
Distance from star 129 million km on the inner edge of the habitable zone.
Illal used to be a sub tropical planet covered in dense jungle and desert. Now, after many decades of terraforming, deforestation, strip mining and over development, it is covered with technology and It's atmosphere is just, mildly toxic. Many alien artifacts and some ruins have been unearthed during the colonization proses. No one knows if these were put here by an indigenous population, or a former colony of some, as yet unknown, alien race. Illal has two moons. The closest one is named Fennon. It is a large moon, being slightly smaller than Mars, with comparable gravity. It has a thin, but breathable, atmosphere and is still undergoing terraforming. A large proportion of the people who left Illal because of the virus have relocated to this moon. The second moon is called Desos. This moon is quite small and has no atmosphere.
------------------------------------------------------------------------------------------------------------------------------------------------
Etal

Third planet from star
Size: Diam 11376 approx size of Venus
Mass 0.86 Earths
Avg Temp -4.51c
Orbital Year 1.42 years
Length of day 2.73
Distance from Star 1.15au
Etal is a cold world on the outer edge of the habitable zone. It has a breathable, but thin, atmosphere and has been colonized. It no longer has any large bodies of surface water, but it does have hydro thermal vents and some lakes. There are large bodies of liquid water under the surface. There is life on Etal, in the form of vegetation, in and around the vents and lakes. There are also some higher life forms, but these have never evolved past the insect stage. There is a high amount of Caverite on this world, so it is mined extensively.
-------------------------------------------------------------------------------------------------------------------------------------------------
Kalec

Forth planet from star
Size: Diam 7838km
Mass 0.14 Earths
Avg Temp -69.4c
Orbital Year 2.83 years
Length of day 1.03 day
Distance from Star 2au
Kalec is known as the shattered planet. Mainly composed of ice, with an iron core and a rocky inner mantle. Kalec get it's distinguishing marks from a collision with a smaller body, approximately 14 million years ago. The collision shattered the planet, which then coalesced again.
Kalec has one moon which was formed from the remains of the body that hit the planet. Kalec has a thin atmosphere and gravity comparable to Mars. It's surface is rich in mineral deposits, including Caverite, so is extensively mined.
---------------------------------------------------------------------------------------------------------------------------------------------------
Maeff

Maeff (pronounced, May-ef)
Fifth planet from star
Size: Diam 139822km
Mass 1.18 Jupiter's
Avg Temp -147c
Orbital Year 11.9 years
Length of day 9.93 hours
Distance from Star 5.20au
Maeff is a large blue gas giant mainly composed of hydrogen, helium and methane. It has an extensive ring system and 14 moons. The moons are mainly composed of rock and ice. The inner most moon, named Foenus, has a thick atmosphere which is highly toxic, but it has an average surface temp of 14c due to continuous volcanic activity caused by gravitational sheer. It has high concentrations of minerals. It has been colonized and is extensively mined.
--------------------------------------------------------------------------------------------------------------------------------------------------
Konsu

Sixth planet from star
Size Diam 116464kmm
Mass 95.2 Earths
Avg Temp -179c
Orbital Year 28.9 years
Length of day 10.7 hours
Distance from Star 9.38au
Konsu is a medium sized gas giant similar in size to Saturn. It is composed mainly of hydrogen and helium. It has a smaller ring system than Maeff. Konsu has four moons and is unusual in the fact that it orbits the star in the opposite direction to all the other planets in the system. It is theorized that the planet was once a rogue that was captured by this stars gravity.
Welcome to Illal.
