The Parvo-Aa/Vekro-Aa System, usually called the Parvo-Aa System, is a major binary system found in the Frealee Sector of Florathel. The system is home to the most populous regions of Saw-Yos, a powerful nation in the region, as well as the homeworld of the Salakela. The Parvo-Aa System is comprised of two stars, Parvo-Aa and Vekro-Aa, the latter of which is much less massive and orbits distantly from the former. Currently, there are ten worlds around the two stars of the system, with a majority, six appearing around the primary Parvo-Aa. The secondary, Vekro-Aa, holds four planets in orbit around it.
Architecture[]
The inner Parvo-Aa System contains three worlds, Coros, Trada, and Kralean. In the outer Parvo-Aa system, there are also three worlds, Saleas, Virelask, and Turosar. Beyond the gas dwarf of Turosar lies a vast cloud of debris, referred to as the Limit Cloud. Beyond the primary star lies the secondary, Vekro-Aa, which orbits within the Limit Cloud and contains four worlds as previously mentioned: Harba, Tarekass, Myra, and Nissara. Various habitation stations and megastructures are sprinkled through the entire system, which contains a massive portion of its population.
Planetary Bodies in Detail - Parvo-Aa[]
Coros is currently the first planetary body from Parvo-Aa, and is a sunblasted lava world orbiting alarmingly close to the surface of Parvo-Aa. Coros, once known as Rathelis is known for being the homeworld of the extinct Corvelmar, one of the most influential species of ancient Rukelian Empire, who wiped themselves out in war a few thousand years after the fall of said nation as the Woni swept over it. In the time of the Corvelmar, Coros was a lush world orbiting within the main sequence Parvo-Aa's habitable zone. However, in the intervening years, Parvo-Aa has expanded, moving the habitable zone outward to Saleas and Virelask, and destroying any life there may have been. Coros' surface is being thoroughly searched for ancient artifacts which may advance science in Florathel by thousands of years. Coros currently has no moons, with all of them being mined for resources, but it has many asteroids in its lagrange points with a curious amount of aluminum, a metal which is almost never found in asteroids.
Trada is currently the second planet in the Parvo-Aa system. In its day, it was a cool, rusted world with large ice caps on both poles, likely terraformed by the Corvelmar. Now, however, it is a barren world, with almost no atmosphere and certainly no life. Trada's surface is a heavy research site, as unlike Coros, it's surface wasn't partially melted, meaning that ancient artifacts from the Corvelmar may have been left behind. Trada is covered in straight canyons criss-crossing the surface, and although some have them have been destroyed, most of them are in perfect condition. These canyons often have modern cities constructed on the walls for researchers to live in, and the planet is a great tourist attraction.
Trada has one asteroid moon:
Volsca
Kralean is the third planet in the Parvo-Aa system. In its day, it was a cold, icy world. Today, its surface is trapped under two hundred standard atmospheres of pressure, the equivalent of having over three thousand elephants standing on every square inch of your body. Because of this extreme pressure, anything on the surface can't even evaporate, being pressurized into "hot ice", which means that even today, not a single individual has touched the surface of Kralean.
Despite this, there are millions of people living in cities floating in the white clouds connected by various flying vehicles and even vast bridges. The population of these cities is roughly two hundred million individuals all gazing at the endless clouds. These cities aren't just for cosmetics, however, as they are slowly stripping the nitrogen and carbon dioxide off of Kralean, potentially opening up the possibility of terraforming.
Kralean has two moons:
- Alydan
- Deviran
Saleas is the fourth planet in the Parvo-Aa system, and a former moon of the gas giant Virelask. Saleas is the home of the Salakela species, and capital of the Economic Federation of Saleas. Saleas and its moon Heleas were both similar icelocked waterworlds, fully covered in a thick crust of ice, until Parvo-Aa expanded into a red giant, bringing them into the habitable zone. As this happened, life evolved much faster, evolving to intelligence very soon after this development. Today, Saleas is an icy world with vast gaps between the ice, where the water shows through into the surface.
Saleas has three natural satellites:
- Heleas
- Paea
- Fras
- Eknar's Ring
Virelask is the fifth planet and first gas giant in the Parvo-Aa system. Virelask is the largest planet in the system, and contains seven major moons and untold numbers of minor ones. The planet is much the same today as it was during Parvo-Aa's main sequence, but some of its moons are slowly melting, and have been heavily colonized by the EFS. Similar to Kralean, Virelask holds billions of people in floating cities above the vast orange cloud tops. Two of Virelask's cities are notable for staging mock wars between each other, as a great game, making them a massive tourist attraction for the planet.
Virelask has seven major moons:
- Delek
- Torkash
- Yelasrea
- Verra
- Reeser
- Leelik
- Morod
Turosar is the final planet which directly orbits Parvo-Aa, and has remained much the same since its formation. Turosar is what is known as a "gas dwarf" world, which is a planet on the low end of gaseous planet sizes, and it orbits near the beginning of the Limit Cloud, which means that it has an outsize number of minor moons for its size and distance. Turosar likely formed closer in and was ejected by Virelask, and its two major moons were likely captured as well, destroying any original moon family. Turosar does not have a very large population, and it's mostly ignored on the interstellar stage.
Turosar has two major moons:
- Theletma
- Taisel
The Limit Cloud is the official name for the clouds of comets and other debris extending over a light-year from the central star. The Limit Cloud contains several dwarf planets, some of which contain populations of hundreds of thousands of people.
The deep freeze of the Limit Cloud is often use to make computing processes more efficient, so many virtual reality computers are located here.
The Limit Cloud contains trillions of comets and thousands of dwarf planets. Only the most major are listed here:
- Tunuras
- Vidori
- Laitheia
- Daiter
Planetary Bodies in Detail - Vekro-Aa[]
Harba is the closest and largest planet orbiting Vekro-Aa, and the second largest planet in the entire planetary system. Harba is a hot, sunblasted gas giant, with little to no non-robotic population. Plans exist to move Harba outward and possibly construct a shellworld.
Harba is surrounded by a set of orbital rings which mine gases from its exceedingly thick atmosphere, and accelerate them at close to the speed of light, eventually fusing them into heavier elements to construct stuff like space stations, which will be spread out around the system for individuals to inhabit.
Harba, being so close to its parent star, only has one alarmingly close moon:
- Hesaia
Tarekass is a medium-sized world similar to Saleas, which has been aquaformed to be like Saleas. Many Salakela live in its oceans, constructing vast towers similar to their homeworld. This makes Tarekass the second most populated world in the system, counting Saleas and Heleas as one place. Tarekass is a tidally locked world, so its entire night-side is locked in kilometers of ice. Because of this, some are throwing around ideas to melt this area and possibly spin up the planet.
Tarekass is the most important world orbiting Vekro-Aa, and has upwards of 70% of the entire system's population. Tarekass is also the seat of government of the Vekro-Aa County, which is the smallest county on record, only containing the secondary star of this system because of both stars' dense populations.
Myra is the third planet of the Vekro-Aa System, and the second smallest. Myra is an ice-locked world that has been cloaked in ice since it was formed. Upon close investigation, the planet contains vast networks of tunnels running through the ice, to various huge hollows, that seem to be filled with abandoned cities. It was likely colonized in its early days by the Corvelmar, who most likely dug these tunnels in response to the great war. Because of this, Myra is a top scientific research site, with research teams descending into the catacombs often. They have found cryogenic pods, and they may find a living individual inside one too. Who knows what the future will bring?
Myra holds two moons in relatively low orbit around it:
- Tenvao
- Vucuris
Nissara is the final planet of Vekro-Aa and the third largest planet in the system. The planet orbits close to the edge of Vekro-Aa's sphere of influence, and contains a vast amount of material and stuff surrounding it. Nissara, due to its distance, has a relatively low population, but its interesting set of moons makes it a tourist attraction, however minor.
Nissara has a significant population floating in cities just above its purple-colored-clouds, and even has miniature cultures restricted to certain cities. This makes Nissara interesting not just for planetary scientists, but for sociologists as well.
Nissara is very interesting in that radar from some of the floating cities has sighted something very large moving far below. They have sent down pods which should survive pressures far above that where they are going, but none have returned, with mission controllers hearing only a crack in the glass and a scream.
Nissara has six major moons:
- Gaabos
- Terubis
- Bosinda
- Umbura
- Donus
- Wirothea
