Ruaor, in grand terms, is a very unremarkable planet. It is a hot, tidally locked Selena world with a very thin and tenuous atmosphere made up of Krypton and Xenon, and is piratically made entirely of rock. Despite this, it, and its sister world, Roaur, are viewed as very scared by the Ugnarain people.
Originally, Ruaor was part of a duel-planet system with its sister world Roaur. However over time the two gradually drifted apart, becoming independent bodies. While Ruaor's gravity would capture the dwarf moon Penala, Ruaor would keep the majority, Souana, Vagak, and Haka respectively.
Though being tidally locked to Ugura, it does not receive nearly the same amount of radiation from it as its sister planet. Its day side is permanently very hot, while its night side is very cold.
The population on this planet is forced to be the same as that of its sister planet, Roaur. This is because the Ugnara believe that if one world's population is higher then the other, then that will increase the births of males or females depending on which one has said higher population. In order to keep the balance between the two, both worlds are required to have a maximum population of twelve million.
In Ugnarian mythology, Ruaor was the personification of the female sex and the older twin to Raour, the personification of the male sex. The two of them would be the first offspring of the mother creator god, Urgutu, and the father creator god, Ugura. When Raour came into being, the Ugnara, and all other life on Urgutu could be born with the female form. If a heterosexual Ugnara couple was wishing to have a daughter, then they would pray to Ruaor in hopes of having one.
Ruaor formed alongside its sister planet, Raour during the formation of the star Ugura on 3,026,000,000 BCE. Its dwarf moons, Souana, Vagak, and Haka would form alongside them.
Ever since their formation, the two Selena worlds would gradually drift apart. Ultimatley culminating around 1,400,400,000 BCE when the two would escape each other's gravity, becoming independent bodies. Its gravity would keep the three aforementioned dwarf moons in orbit around it.
On 9980 CE the Ugnara would land on the planet. After mapping out and exploring its surface, they decided to begin construction of vast domed colonies across the planet. The first of these colonies finished construction on 10010 CE.
Once the Ugnara Kingdom joined the Ambrosia Alliance of United Systems, Ruaor would join Q.U.I. An organization that exists for the progress and betterment of Ambrosia Alliance controlled mining colonies.
