Cosmoria contains one hundred stars. It is home to a vast number of nations, with whole star systems rarely falling under the control of a single polity. To control an entire star makes a civilization far larger than the vast majority to have ever existed.
Argothiya is a medium-sized star known for its importance in the history of Celathiya and the wider Core Worlds Alliance. Home to both the Viphians and Timporians, every world orbiting this star hosts an ecosystem of some sort. The gas giant of Vossen serves as the capital of the Commonwealth of United Economic Nations, the planet sporting an immense double ring structure. Between the rings are vast counter-rotating cylinders that supply a great deal of living area.
Arlioux is a medium-sized star best known for the large clouds of dust that orbit it. Astronomers from across Aylathiya made note of the regular anomalous dimming of the star. The clouds of dust represent a valuable store of resources, but a large number of minute "shepherd planets" keep the dust largely diffuse. The system has only one major planet, Thalsiedeln.
Ayauyu is a small star orbiting the massive black hole Nocturne. It is dominated by a large spinning ring-like structure that is made up of the planets once in the system. While Sagittarium finished the structure, it was built over tens of thousands of years by previous civilizations. It is often compared to Eos, a star system with a fairly similar situation.
Byutix is a small highly-unstable red dwarf who has a binary twin, Helyar. The violent star somewhat regularly emits vast flares that have destroyed all but the most distant of its planets. The system is full of debris from these worlds that has coalesced into a diffuse disk. One such flare was so powerful that it destroyed the atmosphere of the planet Shosturan around Helyar. The event became a major event in the Neo-Terranist religion.
The minute red dwarf of Cephei straddles the line between brown dwarf and star. It was difficult to prove that hydrogen fusion took place in the core, but it was eventually proven to take place in a millionth of all fusion events within it, technically making it a star. Most of the faint star's light comes from Deuterium and Lithium fusion. The star was originally colonized by Sedrua but was later taken by the Quintet Payotari Association before being retaken by Lowyzyol.
Demiurge is one of two neutron stars in Aylathiya. Despite its small size, it is one of the most obtrusive objects within it. Much of Eos is rendered uninhabitable by its furious release of radiation. In the past, there was a large structure around it, built by the Triumvirate Civilization that spared Aylathiya from its punishing radiation. It was destroyed during a war between Aztaya and Florenta in 81,277 CE.File:Divline.png
Elegy is an ultra-cool red dwarf that numbers amongst the smallest stars in Aylathiya. It orbits the black hole of Nocturne and hosts a very small population. The low metallicity of the system has resulted in a very small number of planets mostly made up of carbon. It has almost always been left to its own devices by Sagittarium, rarely receiving a seat at the table. The eight billion souls that reside in this system have some of the lowest quality of life in all of Aylathiya. The economy has no ability to grow and depends heavily on imports to survive.File:Divline.png
Eos is an ultra-low-mass Red Dwarf that is bested only by Cephei in minuteness. The star would be utterly unremarkable were it not for the absurdly large megastructure located around it. Technically orbiting this structure, Eos and its disk have been an incredibly important part of history, with nearly every major empire in the history of Aylathiya having some claim over the structure. It predates even Father Zaphenim and the First Aeternal Society. The most likely candidate for its construction is the state of Hyperion within the Lareas Alliance.
Eos is mostly controlled by the Greater Martial Consilium, a multinational congress made up of nearly every nation in Martial Space. The Consilium's capital city of Scipio is located on the megastructure. Several planets orbit the disk, but are usually considered to be satellites of the star by convention.
Eylanse is a red dwarf star that was the center of Sedrua for most of its modern history. It had been inhabited on and off many times by various civilizations in Aylathiya, making records and artifacts on the planet quite cosmopolitan. After the fall of Sedrua, the star became a stronghold for the federal government of the Commonwealth of Aggregate Aylathiya but, due to fears of a resurgent Sedrua, has no independence. The component states of the Commonwealth each have business in the system, much to the chagrin of the native Bahattes who have consistently struggled to create a state for themselves after millennia at the top of Aylathiya.
Gira Gira is a large Red Supergiant located in Aylathiya and is one of the most massive stars therein. It is home to the Phaethon system responsible for maintaining the Eos megastructure. There is one independent state in the system, DELYATU.
Gruxugawa is a somewhat small main sequence yellow star home to the Kephins species. Historically, it was an important history in Sedrua and remains important in the nation of Vaspujian. Other polities reside in this system as well, such as Avolast and Celathiya who both control large tracts of territory in the system. Gruxugawa boasts a diffuse cloud of energy collectors that, together, have a living area greater than the planets in the system.
Hanabi is a unique object in Aylathiya and one of its two Neutron Stars. Unlike Demiurge, Hanabi is a Thorne–Żytkow Object, meaning that it is a giant star that had absorbed a neutron star in its past, replacing its core. On the surface of this neutron star, a sustained fusion reaction takes place that yields strange products. The system is only about a million years old. Its planets were destroyed by the neutron star colliding with the original red giant or were ejected from the system.
Hanabi is valuable not just for the high concentration of heavy metals around it, but the abnormally high levels of the element Orichalcum, making it a tremendously valuable system. Hanabi has changed hands many times and currently has no controller by treaty. Despite this, bases from the Occult Galaxy Project can be found around the star.
Hearts is the white dwarf binary twin of Odo, its name deriving from the ancient religion of the Civese who believed that the small body becoming visible in the night sky represented a change in heart for their patron deity. In the past, it possessed an impressive accretion disk and may have triggered several novae, described by the nearby Civese as divine judgement that made leaving underground caverns hazardous for several months at a time. Currently, the Poratus megastructure exists around Hearts, a sort of Recurrent Nova Engine that not only shields Civese worlds, but also gathers much of the power released by the explosions. Every Civese nation, Sagittarium, and the Commonwealth of Aggregate Aylathiya lay claim to portions of the megastructure.
Helyar is the orange dwarf binary twin of Byutix. Despite interference from Byutix, Helyar maintains a respectable number of planets that are remarkably close to each other. Helyar had historically been an immensely important system; worlds within it have been the capital of interstellar empires several times. Most of the infrastructure built during those periods has fallen into disrepair however, as the system lost all of its power. Currently, the Kyan Commonwealth claims most of Helyar, with outposts from the Confederacy of Borealis and Thulcandria making up most of the rest of the population.
L'Starte represents the origin point of nearly all life in Aylathiya in some way or another. Being home system of Ma'eau, it has the most diverse and robust ecosystems in all of Cosmoria. Despite being non-intelligent, the ecosystems are still capable of large scale organization and self-management. L'Starte is divided between the nation of Naidaro, Paladins that worship Ma'eau, and the Duchy of Royer.
Lycurgus is a small star that, despite its small size, has been starkly divided for much of its history. Hosting the planet Sakijast, home of the Arkhosian species, the planet never saw a unification of its nations. Instead, they became space-faring on their own, warring with each other just as they had before they reached space. After some time, the Arkhosian Order and the United Provinces were the two major powers on the world and system broadly. With the construction of a Dyson Swarm well under way, these two powers, and their vast cohorts of vassals, would continually compete as they expanded beyond their home system. Sedrua would conquer both nations after some time. The system is currently a part of the nation of Arkholst, a member of the Commonwealth of Aggregate Aylathiya.
As for physical properties, the star has more usable territory than most systems its size. The small planet of Hitogawari was harvested over thousands of years by the Order, and the moon of Stetsett by the United Providences. Both worlds would contribute to a massive Dyson Swarm that remains mostly in tact. A brief period of stellar-level Kessler Syndrome, that is the creation of a deadly cloud of space junk that makes travel impossible, tore up many of the habitats. To this day, a fine dust surrounds the star in a sphere.
Mili is a unique giant star and the brightest in Aylathiya after Gira Gira. It shines in such a way that, in the night sky, the faintest hint of green could be seen, so faint that one has to essentially convince themselves its there to see it. Mili has a powerful magnetic field and a heliosphere that encompasses its "binary" twin of Medb. Mili has a great deal of infrastructure around it that gives it about a tenth as much living space as Eos. The star has very few planets of its own.
Nocturne is a large black hole straddling the boundary between Aylathiya and the core of Cosmoria. Its large gravity allows it to entertain three stellar companions: Ayauyu, Sekhmet, and Elegy. The body has a handful of planets itself. Nocturne has been an untamed wilderness for most of its history, far too large to ever be exploited to its full extent. Once the nation of Sagittarium formed, however, the system had finally become united under a single ruler. This brief period of stability was followed by what was essentially a confederation of independent nobles who ruled their various domains with little oversight.
Odo is the third brightest star in Aylathiya. The star has a large industrial capacity that makes it crucial to the economy of the region. An intensive star-lifting project, using ultra-strong magnetic fields to tear apart stars, is powered by the megastructure around its twin, Hearts. Vast amounts of metal is harvested from the star and shipped across Aylathiya.File:Divline.png
Oratorio is the youngest star in Aylathiya, having only just begun fusion thirty thousand years before the present day. Even so, it has retained the protoplanetary disk that itself is only 500,000 years old. Extensive tampering by Ma'eau, including the strategic placement of shepherd planets prevent the disk from collapsing into new planets. Since protoplanetary disks are quite dense, it has allowed for Ma'eau to introduce a diverse spaceborne ecosystem.
The planets in the ecosystem universally have low gravity, giving the Un'oit an easy task in colonizing all of them. Since they were able to tame much of the spaceborne life in the disk, they resided within a low-tech space-faring civilization that persists in some areas to this day. Outside of the system, the Un'oit have adapted to a technological lifestyle and export a great deal of resources from their system.
Sachitel's Idyll is a derelict system that, while important during the reigns of Father Zaphenim and, afterwards, Mother Sachitel, had fallen into disrepair. Civilizations from across Martial Space raided, exploited, and extracted nearly everything from the system; even Father Isayo and Father Rinayo played a large role in the desecration of much of the system. The reason for this is the large military force, known as the Resonant Divinity. It is an ancient and eternal force that spends a great deal of time gathering and stockpiling resources. In other words, it is a fantastic military target and thus has been treated as a sort of autonomous mine.
The center of Zythyn Civilization, Sakia is a major system for Lowzyol and Aylathiya broadly. As one of the nodes along the Anemoi Line, the system has always hosted great ports and a high population. The Zythyns, however, were only involved in this trade as Sedrua rose to power. Before then, they were simply ignored on their home world of Lokira. Worlds such as Vode served the primary purpose of trade. Most worlds have layered artifacts dating back thousands of years as different civilizations rose and fell. Consequently, the system is quite resource poor, forcing the inhabitants of this system to rely on outside systems. This was a major driver in the history of Lowzyol whose large population consistently demanded cheap goods, forcing leaders to expand elsewhere.
Sekhmet is a medium-sized star orbiting the black hole of Nocturne. Its most distant satellite, Sekhmet has always been the most independent of the systems under the control of Sagittarium. Despite being so distant, the star has only retained its three closest planets, a series of terrestrial worlds whose population represents over an eighth of all of Sagittarium's people. Despite the relatively small population, Sekhmet hosts more of Sagittarium's industry than all other systems save for Nocturne itself.
The system hosts a large Ekrosian and Vlanoan population who make up the self-ruling republic known as Rendell. Other nations in the system are protectorates of Sagittarium, colonies, or the personal property of nobles who often act with little oversight. Economically-productive regions are ruled directly from Thalia.
Seycara is a large star that by all accounts should have died ages ago. Tampering by Ma'eau has kept the star alive for millions of years longer than it should have survived. Extensive infrastructure keeps its death at bay, supporting the aged star against the immense pull of its gravity. Consequently, most of its planets have long since been destroyed, with the remainder hosting life fitting for this zombie of a star, the Marred Life. The innermost planet orbits within the star, its dim parent not even having the energy to destroy it. Beyond this planet, the Marred planets host life hostile to nearly all species in Aylathiya.
Surayea is a medium-sized star nearing the end of its life. Over the last one billion years, the planet of Gohbrin orbited so closely that the silicates on its surface melted, creating large seas. Ma'eau took advantage of this liquid to seed the planet with life. A unique form of life based on Aluminum. Most of the planets around the star have large mirrors around them, concentrating enough of its light to make them habitable for the Orcubor, a species who needs temperatures of at least 2,000 degrees Celsius to survive.
Tryvya is a small red dwarf with only a single planet, the world of Ommekha. The system is free of dust because a contingent of Administrivae tirelessly work to keep it clean. As for its one world, it is perfectly smooth, spherical, and has a consistent density throughout itself. It is made up mostly of ultra-clear quartz. Standing on the planet, one would be able to see all the way into its mantle, giving it a faint orange glow. There are numerous asteroids, particles, and comets that share the same perfect shape which collectively orbit the perfectly spherical, stable, and free of metal star that is Tryvya. Tryvya orbits The Administrator itself, a vast construct that ways about 1.2 M☉.
Wik'Jawum is the home of the Ror Units and potentially the oldest civilization in Cosmoria, the so-called "First Civilization." This ancient civilization, over ten million years old, was destroyed by the first known Noospheric Disturbance, resulting in a runaway restructuring of the matter on the planet D'Naevium, forever altering its surface and the life it contained. The system is currently under the control of a handful of orders of Paladins, such as the Alkan Order and the Vespanic Order.
Ynnud is a very small hydrogen-poor star that appears billions of years older than its actual age. It formed in a region so devoid of hydrogen that it almost immediately began fusing helium in its core, giving the star its unusual spectrum. Ynnud was important throughout the history of Aylathiya as the system changed hands many times in history; it was essentially a frontier system. Currently, it is administered by many of the nations that once laid claim to it and several home-grown civilizations.
Auriminos Laeschaude is a large system that gravitationally dominates the center of Azurullya. Within its center lies the titanic Auriminos, a black hole bested by none in mass. The heaviest individual object in Cosmoria, except for perhaps the High Warlock, Auriminos is accompanied by over 100 satellites, nine of which being massive stars.
Dexotrau is a star permanently locked in the state of a supernova. Despite having temperatures well in excess of one billion degrees kelvin, the star has yet to fly apart. Every year, the amount of iron that it spews out increases, suggesting a lifespan to this phenomenon.
Caligar is technically an unclassified star, but in Lowiras it is considered a Crimson Eye, a large red star with unique properties. It entertains five worlds, including Caliyon which is the home world of the Lacertians.
Ithillid is technically not a star, but in Lowiras it is considered to be one. It is made up exclussively out of high-energy Corporus Noum. Its sole planet hints at the existence of an ancient civilization.
Jullyt is technically an unclassified star, but in Lowiras it is considered a Magenta Mirage, a small star that mysteriously emits visible light only towards the top and bottom of the spectrum. It entertains five worlds, including Wyre which is the homeworld of the Griyosht.
Suryalo was a large yellow-white star that had since become a White Dwarf. At the end of its life, it swallowed many of its worlds, leaving behind only three. Despite this, the Revacens were able to evolve on Arec.
The Brown Dwarf Medb is technically the binary twin of Mili, but since the body has never undergone fusion, it is relegated to the Brown Dwarf category. Despite its status, Medb was still able to sustain a thriving ecosystem around one of the moons of its only planet, Tuirne. The moon of Eithlinn gave rise to the Dotsk species, whose exploits allowed them to create Dotskgard. This fortress nation of trillions has resisted nearly all attempts at conquest. The ancient state had created a vast fusion array powered by the readily-available gas Medb contains.
Amarent is an anomaly of a world that is currently poorly-understood. Dating methods consistently return an age far too old to be composed of the heavy elements it is. With a unique core made up almost entirely of lead, the planet has a weak magnetic field that does little to protect it from the punishing radiation of interstellar space. Amarent has been under the control of Sedrua since it was first discovered, but is currently not claimed by any one nation. Even so, forces from the Commonwealth of Aggregate Aylathiya occupy much of the world and often engage in conflict with forces from the Cabal of Amaranth Truth and the Church of the Fae Queen.
Amarent has a high concentration of Amaranth energy throughout it, a force believed by many to pervade all of reality. This results in the space around the planet being both highly unstable and highly dangerous. The result is the manifestation of Ambrosian Remnants, fragments of a story that adherents to many religions obsessively piece together. Many of these remnants are physical objects, relics, or even records that describe civilizations that have never existed. Other remnants are spatial or temporal anomalies that temporarily induce hallucinations in any nearby intelligent organism, usually describing important, if not fictional, events.
Berceuse is a barren world whose only atmosphere is a cloak of radon gas produced in large quantities by the planet's remarkably radioactive mantle. There are bacteria that thrive in the core that create large tree-like structures which take advantage of the mantle's heat. Since the planet is home to a great deal of radioactive material, it was highly sought after for much of history before cheap fusion reactors became common. Since only the largest of craft can bare the load of a fusion reactor, however, the planet's strange supply of elements is a major source of income for the planet's mostly Un'oit inhabitants.
Etude is a rogue Ice Giant that possesses a faint ring system and seven moons of varying composition. It has the highest Un'oit population outside of their home system of Oratorio. Despite its somewhat isolated position, three of its moons have populations in the tens of billions thanks to large subsurface oceans created due to tidal heating. This heating is a relatively recent phenomenon and, thus, the system has no native life to speak of.File:Divline.png

Eye of Aylathiya, often including a "The" in its name, is a large rogue planet surrounded by a megastructure for which it is named. This legendary device was activate twice in its history. The first time, in 59,122 CE and second in 96,378 CE. The former activation, which was an attempt to resurrect the Angels, killed Mother Sydiah and plunged Sedrua into financial ruin. The second activation, however, resurrected all of the Angels. This would eventually lead to the War of the Ancients and Aylathiya's Ignominy.
Sedrua built a similar device around the star Ayauyu which was also successfully activated. Unlike the Eye of Aylathiya, which is currently barely inhabited, Ayauyu hosts a fairly large population.
