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.
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, with its large mountain ranges ranging thousands of kilometers, or the dangerous Glacium.
