The Aureiga-Selos System is the planetary system composed of the planets Aureiga and Selos. It is located in the Melyos System, in the Via Sagittaria Galaxy.

Aureiga

I am the first to see the whole of this beautiful world on which we live. We should not destroy her for short-term gains but preserve her. (Laia Geitas, first Humeiga around Aureiga, 25/07/16,848 BCE)

Aureiga is a terrestrial planet harboring multicellular organic life located in the Melyos System, the homeworld of humeigas and the capital of Regnum Aureiga.

Overview

Aureiga is an average-sized terrestrial world, with the estimated mass of 1 Standard Terrestrial Masses. It's diameter is around 12,756 kilometers. These properties combined give the planet a gravity of 1G, which is adequate for most sapient species. Aureiga is in a binary with the planet Selos, which also keeps the axial tilt of Aureiga stabilized. Aureiga has a temperature of around 6 °C on average.

Aureiga has a nitrogen-oxygen atmosphere with a pressure of 1 Standard Atmospheres, which is perfectly suitable for the majority of carbon-based lifeforms.

Geography

As Aureiga is cool world, there is hardly any hot desert, and large ice sheets and tundra are prevalent across much of the planet. The planet is mostly covered with grasslands, plains and forests, as well as seas and oceans (57 %). Oceano Greto is the largest ocean. The planet has 6 continents:

  • Zìa
  • Aurùp
  • Tareita
  • Greas
  • Kàleip
  • Naed
  • Isù

The highest peak on Aureiga is the mountain of Alcim on the continent of Aurùp at 8,394 meters above sea level.

The continent of Aurùp is famed for the great tundras spanning much of its area.

Fauna

Aureiga contains many very interesting species scattered across its surface. There are so many that it is still believed that there are still more to be discovered.

Lyne

The Lyne live on the tundra of Tareita. They have an omnivorous diet, but eat mainly meat. With their fur, they can thrive in the deep cold of their main habitat. Most Lyne have a yellowish eye color, though it is not unheard of to see a Lyne with green or purple eyes. Lyne have famously sharp hearing. On average, they can hear the crunch of a dead leaf from 15 kilometers across a plain.

Gird

The Gird are native to the savanna of Kàleip, but are now spread all across the planet. They have a primarily vegetarian diet but can be scavengers if need be. The Gird can run at nearly 90 km/h for 10 minute bursts, or around 35 km/h for long distances. This animal was one of the first domesticated for travel across the continent by the native Humeiga tribes in prehistory, and they were spread across the world for easy travel before invention of cars.

Cities

Aureiga has many cities. Most of them are vastly expanded forms of ancient cities, because people generally move towards concentrations of population, and many are underground or in the sky. Most are fully self-sufficient.

Zàlepar

Zàlepar is the capital city of Aureiga, located on the continent of Kàleip. It was one of the first cities to be constructed in the ancient history of Aureiga, and has been continuously inhabited ever since. The city is also famous for the Capitol, the district of the city where all government services in the Regnum Aureiga are conducted. The population of the city is approximately 910 million inhabitants. The city's outskirts are notably more modern than the so-called "old town" near the center, and if someone used to advanced cities visited the Old Town, they get a sensation of going back in time.

Dèya

Dèya is the most populated cities on the planet with 14,231 million inhabitants. Interestingly, it was founded relatively recently, as many of the other cities were growing "too crowded" at the time of its founding. The city is famous for its unique elevation, looking almost like a craggy pyramid.

Selos


The distant desolation has been conquered for the betterment of all people. (Alys Ridget, leader at the time of the landing of Valiam Merida on Selos, 13/04/16,799 BCE)

Selos is a barren, lifeless world in a binary system with Aureiga, located in the Melyos System. It is the first colony planet of the Regnum Aureiga.

Overview

Selos is the only natural moon around Aureiga, has a mass of 0.012302 terrestrial mass, a diameter of 3,474.80 kilometres and a surface gravity of 0.166 G. The axial tidal of this moon is of 4°44'40.49" and is tidal locked to the planet, ie the same face of the moon is always face to the planet. But due with the eccentricity of the moon around the Aureiga-Selos barycenter, inhabitants of Aureiga can see roughly 59 percent of Selos' surface over its orbital period, and vice versa.

Selos is the first object other than Aureiga to be explored and colonized by the Humeiga. Selos has very small amounts of volcanic activitiy across the surface as well a very weak magnetic field. Selos has no substantial atmosphere, as most gases can easily escape its gravity. Due to its distance to its sister world of Aureiga, they cause tidal forces on each other, resulting in Aureiga's sea levels changing, and the crust of Selos being flexed enough to crack it in some places, creating scattered volcanoes.

History

Due to the surface color of the planet, most believed that life existed on the plains of Selos, like the plains on its sister planet Aureiga. But in 16,778 BCE, with the first probe image of the surface of Selos, it was absolutely confirmed that the surface was a lifeless desolation, with rocks strewn across the surface. In 16,799 BCE, the first Humeiga on the moon, Valiam Merida.

With analysis of rock material from Selos, there are many similarities with rocks of Aureiga. One theory to explain this involves another ancient world of the Melyos System smashing into ancient Aureiga, blasting it to pieces, and causing Aureiga and Selos to coalesce in their modern form.

Cities

Cities on Selos are contained within domes, with a large underground section. The first, founded in 16,610 BCE was named after the first Humeiga on Selos. It is on this city there are a party to celebrate the event in question and some district have name of the crew of Valiam Merida. The second city took the name of the commander of the first relatively long-term base on Selos, Laia Geitas, and was founded in 16,515 BCE.
