Garrea is the innermost planet in the Dorok System, the capital of the Free Nation of Garrea, and a major world of the United Nations of the Florathel Galaxy. Garrea is relatively desolate compared to most homeworlds, due to its tidal lock to its parent star and the resultant temperature extremes on the subsolar point and night side. As of now, Garrea has a relatively low population compared to other major worlds like Artaclate and Carlea. Currently, Garrea is the most powerful member of the FGN Core Worlds, and is a major influence in the nation as a whole (aside from the whole capital thing).

Properties

Garrea is relatively small, being only ~4,700 km in radius, and its mass is similarly low. Unlike many inhabited worlds, the planet's biodiversity is relatively low, due to its extremely harsh conditions. Aside from this, and the smaller scales, Garrea is very much habitable. Its system is more oxygen-rich than normal, and as a result Garrea has more tectonic activity and a stronger magnetic field than what would be expected of a planet this size, nearly 6.5 billion years old.

Atmosphere

Garrea's atmosphere is relatively thin, due to the effects of highly powerful bursts of solar wind from its parent star. These flares are mostly negated by Garrea's powerful magnetic field, otherwise the planet's atmosphere wouldn't even exist. Due to its advanced age, Garrea also has a high percentage of Argon compared to younger planets.

Aside from these statistics, Garrea's atmosphere also contains little oxygen, due to the paucity of plant life here. The native Rorazals have evolved to be perfectly comfortable under these conditions, but it is uncomfortable or even lethal for most other oxygen breathing species.

Orbit & Rotation

Garrea is the innermost planet orbiting the M-type star Dorok. As Dorok is a red dwarf, Garrea must orbit very close in to allow for habitability, and despite its insanely close orbit of only 14.39 days it is still quite cold. The eccentricity and inclination of Garrea's orbit is negligible.

Garrea is tidally locked due to its distance from the star, and as such rotates in the same period at which it orbits. Due to this, the perpetual night-side of the planet is locked in eternal darkness and is covered in kilometers of ice, and the region beneath the sun is incredibly arid and uninhabitable. Thus, only the the twilight regions are truly inhabited by more than the hardy desert people.

Infrastructure

Although it lacks moons, Garrea has a huge amount of stuff orbiting it. Today, Garrea's sphere of influence is so full that it is impossible to find a location more than 100 kilometers away from a structure of some kind. This makes it very difficult to navigate within it, and as such Garrea has some of the most advanced positioning systems of any planet in the galaxy.

There is also a huge network of artificial orbital rings of varying sizes. These rings are the most efficient way to leave and reach the planetary surface, and are also notable habitation structures. Freely orbiting the planet is a hundreds-of-billions-strong cloud of large habitation cylinders that each have populations of around 4,000.

Another feature of the numerous orbital rings surrounding the planet is a spacecraft railgun, allowing smaller spaceships to be slung at insane speeds out of the system to enable activation of the spike drive. Unfortunately larger spacecraft cannot be fired in this way because they generally are not designed for that kind of acceleration.

Geography

A map of Garrea.

Garrea's tectonic plates are very sluggish, due to the planet's advanced age and corresponding core cooling. However, in the period of time before they began slowing down, Garrea developed a set of seven large bodies of continental crust. Today, three of them are both on the day side and above water, although those three have merged into a supercontinent, Sonian, as of today.

There are two large oceans on Garrea, split by the supercontinent of Sonian. These are the Caleinar Ocean, the larger of the two, and the Avidon Ocean. These oceans were named in prehistory, but no one has any idea why they were named the way they were. Garrea's oceans are much less affected by the temperature gradient moving away from the subsolar point because thats how water works, and as such are more biodiverse than the planet's landmasses.

Most of the supercontinent of Sonian is incredibly high-temperature, and only the twilight regions have anything other than hot desert. As such, the vast majority of the population of the planet lives in the twilight regions, relegating most of the rest of the planet to either autonomous resource extraction or to the bands of wandering desert peoples.

Due to the planet's tidal lock, the entirety of the night side of Garrea is covered in a massive ice sheet varying in thickness from 0.4-4.1 km. As the ice sheet ever-so-slightly makes it over the terminator, it begins melting, creating large freshwater lakes or rivers around its edge. However, most of the rest of the ice cap is completely uninhabitable.

Hidden beneath the ice sheet are three other bodies of continental crust. However, no one knows what they're like because they're under kilometers of ice. There also appear to be vast lakes beneath the ice shell.
