9th moon from Arkkanna, Lies between the orbits of Errios and Kothrann.
Onkoaa, also known as Arkkanna IX, is the ninth moon known for its extravagant ice caps and craters, which contrast the bloody orange color. Onkoaa also has a very rough surface, which, along with the craters, implies that not only did the moon itself have a chaotic past but also Arkkanna's System, which can explain the large rings of Arkkanna and the numerous craters on various--rather many--moons. Onkoaa also has dust floating about, giving the impression that there is an atmosphere. Its ice caps are also made of regular water ice mixed with other compounds. No life has been found here, not even in the ice caps. Another thing that makes it unique is its orbit. It lies very close to Kothrann, offering close views every now and then.
Lore:
Onkoaa is a very unique moon of the Andrean Sector and holds countless mysteries. It is known for being one of the very few barren moons--moons without an atmosphere. Its craters and distance from Arkkanna are other subjects that are taken into consideration. It has ice caps comprised of water ice mixed with other compounds. Onkoaa also has a thin dust layer above its surface, mimicking an atmosphere. It is faint but visible. It also has very rough terrain, with some parts being mountainous and steep, or gradual slopes and flats.
Hyperean Records show that Onkoaa had little to nothing to do with Hyperean Mythology. Even during the Aurean Great War, there aren't many ruins compared to habitable worlds or worlds with atmospheres. However, Onkoaa was heavily mined and used in the past, along with being one of the main sources of resources for the Aureus Civilization. Onkoaan materials were also in better condition than the ones found in habitable or atmospheric worlds, as there was not much erosion and weathering to influence the existence and formation of materials. Because of this, there are many derelict mining, extraction, and excavation sites scattered around the moon. Another thing is that its polar caps were generally left untouched. Of course, various battles and skirmishes took place here, but most of them were not drastic enough to leave a mark. What makes its polar caps strange is the pattern. The pattern is not naturally occurring but that is not what it is about, rather, it is something much deeper. While it may appear to the Korelite-Crystals Plains on Shabol, the ice seems "sentient". It grows without the need for other materials to be present such as water, and its growth is exponentially multiplied when it is in the dark, growing at 42 times that of the norm. The ice is also attracted something unexplainable. It seems that it grows even faster near ships or buildings, and grows around them, almost as if it is encasing it. All of this evidence has led to the idea that the ice, which will be referred to as "Glacium". It seems to also have similar properties to the ice created by Kaither Sars, the Hyperant that dwells on Katharaeas. Another interesting about Glacium is that it is marginally electrically conductive. This is very similar to Korelite on Shabol, which it too is electrically conductive, but to a large extent. Because of these various and many factors, it may seem apparent that the ancient Aureus Civilization left the "ice" caps alone--and for obviously good reasons.
Onkoa is rich in various minerals, metals, and materials. It appears that in the past, it was heavily fortified as it was one of the Aureus Civilization's "Resource Worlds", where it is protected and mined for its resource to fuel the civilization. Of course, there are many common materials like iron, titanium, silver, gold, etc etc. There are some other unique minerals and materials that make this moon unique for them, such as Hadallite, Dorphanite, Aperiolite, Javalite, Bittite, and many others. Some metals can include Rekorium, Gellium, Axnium, and Silacium. Most of these unique metals each have their properties, such as cosmetic uses, durability, strength, and industrial purposes such as resistance to weathering, high density, conductivity, and many others.
Overall, this moon is intriguing, from its large mountain ranges ranging thousands of kilometers, or the dangerous Glacium. From it's conflicted and exploited past, to the now ruins that tower and stand silent over the Onkoaan terrain, forever paused and wrecked.

Apparently US2 lighting is widely different, as I used the same color for Onkoaa from the US2 version.
