哈迪斯星系

Hades is an unclaimed system. It is accessible only through territories controlled by pirates and thus isolated. Hades is best known for the remains of the Hadesian civilization. Formerly claimed by the United Planets of Earth, it was abandoned a second time in 2546. All planets in the system are inhospitable due to an conflict in ancient times which left Hades I, II, and III devastated and contaminated. Hades IV was even bifurcated by an unknown device.
==History==
===Hadesian Settlement===
290 000 - 300 000 BCE SEY Hades was settled by an spacefaring civilization named by the humans 'Hadesians'. They settled on at least two planet of the four planets in the system. They shared a written language and culture. Trade and travel between the planets existed.Loremakers Guide also discussed the possibility that more than one species inhabitated the system: 'One possibility is that they were all settled by three different species. Another is that only one species inhabited all of the planets and then splintered into enemy factions.'
=== Hadesian Civil War ===
Most likely in a series of combats, Hadesians destroyed the atmosphere of the planets they were living, still for unknown reasons to his later rediscoverers. Hades IV was split into two parts by a single doomsday device.
It is not known whether Hades had access to the existing wormholes at this time (probably harming their abilities to expand), or the realignment of the wormholes first isolated them from his parent civilisation (i.e. see collapse of the Oretani jump-point).
===Rediscovery===
The jump-point into Hades (from Nexus) was re-discovered by humans in 2515 by the Merry Crow, a tramp freighter with stolen goods, who hid its discovery.The Galactapedia re-iterated previous information given by the older Galactic Guide. According to the GC the system was discovered in 2515 by the Merry Crow. The GP instead notes that the crew decided to not enter the system and hid the discovery of the jump-point. The GC also claimed that the discovery was 'formally' attributed to Jake Tapps in 2531. An information which did not appear in the GP.
Jake Tapps, former navigator sold the navigation data of the jump-point, after the ship was destroyed and his crew (except Tapps) were killed in 2529. GC notes his reason was to finance his SLAM addiction. The system was entered, cartographed and registered by the Dynamo Corporation in 2531.
Dynamo's exploration ships soon discovered ruins of its former inhabitants. Initial plans to terraform the planets were given up and the findings were sold to the United Planets of Earth (UPE) which claimed the system. The devasted tomb-like state of the planets ruins lead to the nickname Hades. The former nickname was later officially adopted by the UPE.
===Messer Era===
In the time before the rise of Ivar Messer, the system was extensively searched by xenoarchaeologists. In 2541 the UPE retracted their protection to support the Tevarin War effort. The newly formed United Empire of Earth left the system entirely unprotected.The void was filled with treasure hunters and researchers needed to contract private companies for their security.
In 2647, the xenoarchaeological faculty of the Astravin University at Cestulus published a paper which theorized that the Hadesian civilization had been wiped out in a interplanetary war.
Imperator Corsen Messer V later adopted the theory that the Hadesians possessed advanced weapon technology and organized a search effort, which was conducted by UEE marine forces. In the process artifacts and ruins were irretrievably destroyed.
===Post-Messer Era===
After the downfall of the regime, hundred of academic institutions across the signed a petition in 2792 asking the UEE to reclaim the system. Due to the ongoing conflict with the Vanduul the petition was refused.
To this day, thousands of structures have been identified on the planets and artifact and technology hunt continues. Goods excravated or shipped from the Hades System without the approval of the Department of Xenoarchaeology are considered contraband by the Advocacy.
==Etymology==
Hades was named after the greek god and personifcation of the underworld. It was given due 'this grandiose level of destruction' on Hades IV and the tomb-like state of the worlds.
===The Hades Cryptid ===
Travellers to the system often swear that it is haunted. Also known as "Hades Satan", "Tobias" and "Thanatos", the mysterious Hades Cryptid has had reported sightings over the years by Humans, Banu and Xi'an. The creature has been described as lacking skin, with blue veins and blue musculature visible on the being's surface. However whenever someone tries to get a good look at it, it vanishes.
==Gravitational governors==
===Hades===
Hades is a main Sequence Dwarf-F 'blue-white B9 IV' star. If planet II, III, IV had not been devastated by the war, they would probably hardly be habitable today, as they are outside the green band due to the decrease in emissions from the star. The Galactic Guide notes that this observation stands 'in seeming contradiction to the age of other stars in the stellar neighborhood'.
==Planets==
===Hades I===
The only planet which lies in the 'inner edge' of the green band. The cratered planet probably once had an atmosphere. 
===Hades II===
Once settled, the remaining ruins of hadesian cities lying under a thick layer of ash which preserves them from the sharp winds. Most of the ruins above the ash layer has been eroded over time.
===Hades III===
The 'smog planet' planet has a toxic and high pressured atmosphere. Access to the planet is therefore complicated. The extreme conditions have eroded most of the surface ruins but scans indicate ruins have survived under the surface.
===Hades IV===
Hades IV is the famous 'half planet', and is officially designated a '0.5' planet by UEE authorities. The world was split in two distinct halves 'likely impacted by a weapon of mass destruction' . It is unkown if it was ever settled by the Hadesians.
