Uuoea-Esa System

The Uuoea-Esa System is the birthplace of the Unathi civilization. They soon spread from their homeworld of Moghes to the planets beyond, and eventually into the stars themselves.  Despite being an interstellar species, nowhere is more developed than this system, with the Unathi’s spacefaring civilization designed to harvest minerals and energy and return it to their home planet.

Uuoea-Esa

Uuoea-Esa, also known as the Mother Star, is the lifegiver of the Unathi, a F-Type Main Sequence Star, a type of star capable of producing a large habitable zone, similar to Sol.

It has seven planets in its system, as well as many countless Dwarf Planets.  Most of these planets have some form of Unathi habitation, either on the surface, or in orbit.  These habitats have existed for centuries, with many being their own independent state in their own rights.

Yoos

Yoos is a minor rocky body, and the first planet in the Uuoea-Esa System. It is both small and hot, and it has often been ignored by Unathi colonisation efforts.

Yeora

Yeora is a gas giant, lying between the sizes of Saturn and Uranus. It is the second body from Esa, and has many orbital harvesters and facilities vital to the interstellar Unathi civilization.

Measurement	Value
Mass	47.354 Earths 0.149 Jupiters
Radius	8.11 Earths
Average Temperature	110°C
Rotation Period	4.45 days
Orbital Period	3.63 months

Akka’Shar

Akka’Shar is the third body in the Esa System, and is another large Gas Giant, though much smaller than Yeora. Akka’Shar has three moons, Lask, Sten, and Skrep, all of which have been colonised. Akka’Shar straddles the line between Superearth and Gas Giant, allowing for far deeper exploration, and colonisation of the mysterious interior.

Moghes

Moghes is the fourth body in the Esa System, and is the homeworld of the Unathi. It is a rocky, pangaea-like world, undergoing continental breakup. It has two moons, Statt’att, and Zek’Rah, both of which have been significantly colonised and inhabited.

Ssah’hah

Ssah’hah is the fifth planet in the Esa system, and is a small rocky body with no atmosphere. It has never been habitable, and its surface is marked with craters, signs of no tectonic activity.  Despite this, it has been widely inhabited and serves as the Unathi’s most important mineral harvesting colony.

Oe’erg

Oe’erg is the sixth planet in the Esa system, and is a habitable, frigid world, colonised by the most foolhardy and brave of Unathi. It is smaller than Moghes, but protected by a thick atmosphere.  The planet itself is a continental world covered nearly entirely by glaciers and massive ice sheets. Around the equator, temperatures are warm e
