View Zeta Virginis on Wikipedia
The Heze System, also known as the Zeta (ζ) Virginis System, or simply as Heze, is a gravitationally bound system of asteroids and planets orbiting the star Heze located 74.14 lightyears away from Sol. The system, and it's parent star are both estimated to be a young 1.5 billion years old. The system consists of six major planets, Olamide, Petras, Eden, Asther, Pacifica and the captured rogue planet Avalon. The Heze system also holds a number of dwarf planets, the largest of being Odinn, and one red dwarf star, Rouge, also known as Zeta Virginis B.
Heze, unlike Sol, is not separated into multiple regions. Whereas Sol consists of the inner system and outer system, divided by the Asteroid Belt, Heze does not possess a major asteroid belt between the inner terrestrial planets and the outer gas giants (though the planets Asther and Pacifica do possess trojan satellites and form what is known as the pseudo-asteroid belt) and also possesses no starbases to establish sector commands the likes of INCOM and OUTCOM. However, there is a colloquial separation of the inner terrestrial planets of Olamide, Petras, Avalon and Eden, and the outer gas giants of Asther and Pacifica. This division is not recognised by the Sol Defence Corps, but has been used in Naval Development Group official documents.
The majority of planets in the Heze system have recieved minimal research as most attention and funding has gone into researching the anomalous rogue planet Avalon.

Some theories to explain this may be the second star, Rouge, interfering in the planetary development coalescence within the protoplanetary disc. However this does not align with the theorized origin of Rouge originally being a brown dwarf. This is one of the Heze system's many anomalous properties.
Information
Heze's formation in what is referred to as the Virgo Interstellar Dust Cloud occurred 1.5 billion years ago and is one of the only planets in the theorized dust cloud area to retain a protoplanetary disc other than it's neighbor star Syrma. This dust cloud is also theorised to have formed many other stars in the region as well as many stars which make up the Virgo constellation, including again, Syrma. Rotation of mass collecting from mutual gravity generated heat and lead to the formation of the star Heze, whose size did not inflate to large enough sizes to absorb the rest of the dust cloud in it's region, forming a protoplanetary disc that formed seven of the eight major astronomical bodies in Heze. The eighth, Avalon, is theorised to have been captured 200-300 million years ago. While Avalon's albedo fog blocks sunlight from Heze and forces the planet to depend on geothermal heat for life to form, the heat of Heze does allow life to form on the fourth planet, Eden.

Information
Olamide's surface and overall composition consists of high amounts of silicon, with phosphorous and sulfur covering the surface and giving the planet it's distinct colour. There are also believed to be massive deposits of copper and aluminium on the surface of Olamide which contribute to the patches of turquoise rock. Large patches of mountains are found around the equator of Olamide and are believed to be dormant volcanoes organized into clusters.
These mountains are eroding constantly however, as the planet's proximity to Heze means it receives immense solar winds despite Heze being an A-type main sequence stars, which means it has weaker solar winds.

Information
Petras is believed to have formerly been a binary planet similar to Pluto and Charon, whose orbit deteriorated and caused the planets to collide with each other due to orbital interference.
This theory is supported by the many small asteroid satellites that Petras has despite being a small protoplanet. Many of these satellites have had similarly deteriorated orbits and have crashed into the surface of Petras, creating large patches of lava all across the surface of the planet. Other theories include that Petras has captured some of the meteorites and asteroids that typically strike, or that both occur at once.
Petras is the youngest planet in Heze and is composed primarily of silicate with it's meteorite impacts adding a presence of heavy metals.

Main article: Avalon
Avalon, officially known as Heze (/ˈhiːziː/, hee-zee) III, is a terrestrial planet located in the Heze (Zeta Virginis) binary system, located 74 lightyears away from Sol in the Virgo constellation. Classified as an anomalous body by the Sol Defence Corps, the planet is a myriad of dualities - a habitable atmosphere and abundant wildlife clash dramatically with its toxic soil and poisonous oceans. Avalon is covered in a greenhouse fog that partially blocks light from its parent stars, its lukewarm temperature instead coming from the planet's highly volcanically active crust. Avalon is the only planet in the Heze system which is classified as habitable.
Heze was discovered in June 2047 via the transit method of it intersecting its parent star. However, the planet's thick fog had masked its unique properties and was not considered a habitable planet until advanced technologies had allowed scientists to discover its atmospheric composition remotely, prompting it as a prime habitable candidate and marking it for later exploration by the Final Frontier Project.
Information
Avalon is a terrestrial planet slightly over half the volume of Earth, but with twice the density, giving a gravitational pull of approximately 0.86 G, meaning minimal adjustment is required for anyone stepping foot on the planet. Much of Avalon is geologically active, with earthquakes and volcanoes creating hot springs which form steaming lakes. Although it is an uncommon sight, some of these lakes can grow to incredible size, rivaling that of even the Caspian. Despite the otherwise hostile implications set forth by the planet's activity, pockets of life containing fauna and flora exist in patches which surround these lakes, creating a network of oases which are shrouded in a purple hue brought along by the colour of the glowfruit Tree's leaves.
Radiometric dating of bedrock samples as far as 2.3 miles below the surface of the planet have led to the discovery that Avalon as a planet is 3.4 billion years old, nearly 3 billion years older than its parent star, Heze. This has led to the theory that Avalon is, in fact a captured, formerly rogue planet from a distant star system, owing to its highly eccentric orbit and unusual rotational period. Avalon's original star system, as well as how it had sustained life even while rogue, still remains a mystery.

Information
Eden is the third oldest planet in the Heze system after the gas giants Asther and Pacifica, and is the second most thoroughly researched. Unlike the other terrestrial planets, which are untouched, missions have been sent to Eden to research it - an early-development planet almost identical to early models of Earth is invaluable knowledge to scientists. Missions have concluded that the surface of Eden is both extremely toxic due to carbon dioxide and an incredibly cold surface - completely covered in snow and ice - and can only be traversed with use of insulated hardsuits.
Early multicellular life has been found in both oceans and on lands, with both oceanic and surface life measuring centimetres in length. Underneath the snow and ice covering the surface of the planet is fertile soil protected from the toxic atmosphere. Naval Development Group researchers are looking to initiate further missions to Eden as soon as possible, but it is believed that studies will not be conducted until a permanent colony and colonial administration is established on Avalon.

Information
Asther is the first planet in the Heze system to be discovered from Earth by use of the transit method of it intersecting Heze. The planet is 1.3 times larger than Jupiter and is planned to become the economic outpost of the Heze system in coming years similar to how Jupiter is the economic core of Sol, and is to host a major starbase and anchorage. Asther houses many trojan asteroids captured from the orbit of Pacifica, many of which constitute a pseudo-asteroid belt between Asther and Pacifica, with some being flung out into the Oort cloud of Heze.
Asther possesses only two large moons, Redford and Shaori. Redford is notable for it's highly volcanic surface and Shaori is notable for being especially visible from Avalon during their flyby periods, having a larger orbital radius from Asther than Redford. Though no studies have been conducted due to the focus on Avalon, Shaori may contain a subsurface ocean of liquid water caused by tidal heating.

Information
Pacifica was discovered around the same time as Asther, making Heze one of the first stars to reveal two planets at once using the transit method. Much like Asther, Pacifica also hosts a number of trojan asteroids which are largely shared by Asther and Pacifica, many of the trojans being flung from one's gravitational pull to the other before being flung out towards the Oort cloud. Their trojan asteroids together form the pseudo-asteroid belt.
Pacifica hosts three major moons, Mobe, Jasime and Astlana, each of which in close enough proximity to Pacifica to host subsurface oceans which are made especially likely due to Pacifica's introduction of water and ice to the Pacifican system.
Mobe is especially likely to support a subsurface ocean as it's surface is dotted with numerous elevations believed to be geysers dispensing what is believed to be water vapour. Each moon of Pacifica is comprised mainly of ice, with very smooth surfaces with Jasmine being the smoothest object in the Heze system, and each decorated with lineae.

Odinn, also known as Heze VII, is a dwarf planet and the second final major astronomical body in the Heze system. Composed primarily of iron and ice, Odinn appears to have been the core of a former planet. Curiously, Odinn spins almost perpendicular to it's orbit, which is shifted ever so slightly each year by Rouge, which passes close by at one point in it's orbital period. It is predicted that the planet will eventually be pulled into Rouge's gravitational attraction and be destroyed millions of years from now. Odinn has captured few trojan satellites from Asther and Pacifica, however, most of the satellites it accumulates are stolen by Rouge during their near orbit periods. The planet is named after Odin, the chief deity of Norse religion.
Information
Odinn is theorized to be the former core of a planet judging by it's composition of almost entirely iron and water ice. An explanation for how it's former planet had lost all of it's material is several past collisions with other protoplanets on the outskirts of Heze. However, there is little evidence to prove that other protoplanets existed as far out. These planets were either rendered rogue, flung out of the system by Rouge, or formerly orbited Rouge and had their orbits deteriorated over time either due to instability or following the aforementioned collisions with Rouge.
Alongside spinning perpendicular to it's orbit, Odinn also has a very high rotational velocity for it's relatively small size. This may also be related to interactions with Rouge, but since studies of Odinn have been put on pause to focus on Avalon, only speculation can currently explain the many unanswered questions of Odinn.

Information
Rouge is theorized to have once been a brown dwarf star formed in the protoplanetary disc of early Heze, and remained as such for a long time before coming into contact with a gas giant to force it's core to reach critical mass and undergo fusion. Remnants of this gas giant are being searched for as it is unlikely that the planet was rendered rogue by the collision. Alternatively, it could have been absorbed by Rouge which is what caused the extra mass to cause the core to undergo fusion.
