About Cairn Sector

The Cairn Sector is just one of hundreds of thousands of similar Galactic Sectors across the Galaxy. It is defined as an area of space surrounding a point of interest, usually a large nebula or star cluster. In the case of the Cairn Sector, that would be the Firion Molecular Cloud. The Sector expands roughly 700 light-years out from the center of Firion in every direction, and like all Galactic Sectors, its borders overlap with around a dozen others for several light-years.

Major Alien Civilizations

The Cairn Sector has 8 native alien civilizations, 3 of them major civilizations with access to space travel, and one additional transplant civilization. The Cairn Sector is one of only three other sectors in the Galaxy to have this many. Due to the nature of the rise and fall of civilizations, combined with the vast timescale of the galaxy's age, a Galactic Sector could of had thousands of civilizations since the birth of the Universe, and none of them might have been concurrent with each other.

The Vusinor are the most powerful civilization in the Sector, and for hundreds of surrounding Sectors. In terms of technological advancement, they are in the middle of the top 50 civilizations in the Galaxy. In terms of size, they are nowhere close to the top, even with a population of 90 Trillion. They have settled almost every rocky body they could find in a dozen systems surrounding their home system, and have outposts in over a thousand others spread across the Cairn Sector, the nearby Feihia Sector, and the further away Rofiun Sector. They have six Dyson Swarms currently under construction. Their entire civilization is technically a single empire with tens of thousands of semi-independent organizations.

The Vusinor have skin that ranges from dark green for those adapted to live on the equator, to light blues and violets for those that live closer to the poles. Their hair ranges from dark purples, dark reds, and darker greens and resembles seaweed in appearance. They have large eyes that can see quite far into both the Infrared and UV spectrums, but at a lower quality than other species. They are also one of the only alien species in the galaxy that can use photosynthesis as a secondary source of energy and breathing.

((Placeholder space for an image of a Maorian's Face. Working on it))

The Maorian are a long lived civilization with a slow growing population. They continuously and slowly grow throughout their lives. An adult at 40 years old will be 1.5m tall and weigh 75 kilograms, but at the end of their long life, will be 4m tall and weigh 600+ kilograms. Some examples of Maorian have been recorded as reaching 8m tall and weighing more than 1000 kilograms. They are so long lived that adults that were barely 50 years old were on the first "generation" ships to settle a nearby star system, and were still quite able bodied at 2900 years old when the ship reached its destination 12 light-years away.

Maorians have smooth, light grey skin with no hair. When exposed to above freezing temperatures combined with an atmosphere with enough carbon dioxide, their skin produces a constant source of nanocrystals, made of carbon and silicates, which can make them appear to be made of rock sometimes or even appear to look like they are covered pieces of seashells. This shell is quite protective and breaks off naturally after building up enough, but can also be easily washed off after soaking in water for a time. This process is somewhat related to the carbon cycle that occurs on most life-giving worlds. Maorians can also take vitamin supplements to prevent the growth from happening at all, which is preferable in space ships and in space stations.

Home System: The Delvi Star System
Average Lifespan: 85 EYears (150 in space)
Total Population: 114 Billion
Kardashev Scale: 1.05

((Placeholder space for an image of a Regalti's Face. Working on it))

The Regalti prefer to live in space instead of on their homeworlds. This isn't because their homeworlds are dangerous, but rather due to their physiology. They simply live longer in a lower gravity environment, and like any death fearing species, tries to avoid that as much as possible. Nearly all of their species left their homeworlds in an even known as the Exodus.

99% of their species now lives in space in a Dyson Swarm that is slowly being constructed and is expected to be completed in another hundred thousand years or so. Their largest planetary population is on Collena at just over a billion people, while the population in space is around 110 billion now.

The Regalti have semi-translucent skin that is naturally a tan color but appears more red, lighter or darker depending on specific race and radiation exposure, but it has an understructure that can uniformly change into almost any color. It doesn't happen at will, and is due to an expansion of tiny blood vessels just under the skin. They can appear as a deep crimson color, fully green, or blue or purple. Their hair resembles small feathers that grow through their lives and the structure of the these feathers can appear red or blue, and one of any other color depending on the angle you view them from

((Placeholder space for an image of a Yil's Face. Working on it))

The Yil are a short statured, short lived, yellow skinned humanoid species with four arms. They don't have an internal skeletal structure, instead relying on thousands of small, compressed, Argon filled sacs that provide the same functions. They have several strange alternate biochemistries, and can also survive much warmer and colder temperatures, and much more toxic environments than that of other carbon-based life.

The Yil were originally a slave race, owned by the Sseterri, a K1.5 civilization that owned several entire species and tried hiding them from the rest of the Galaxy. The Vusinor purchased the Yil from the Sseterri and then freed them, giving them a system in the Cairn Sector of their own. To the Vusinor, the Yil are better off free, but also better off working for them. Most Yil assist the Vusinor in building their many Dyson Swarms around their many star systems, working in environments that are outright toxic and deadly to most other forms of life.

Dead Civilizations

Across the Cairn Sector, there is evidence for the ruins of thousands of different alien civilizations, separated by many millions of years in some cases. These examples are just a few of many:

  • The Verenthe System has the remains of a dyson sphere and a planet that was baked dry from its parent star over a billion years ago.

  • The Yulan System has evidence of a civilization that was destroyed when a moon sized object crashed into the planet, instantly vaporizing all complex life that wasn't in the deepest oceans. This was over 9 million years ago.

  • The Revenak System shows life with fungal growths all over their bodies, as well as the remains of a civilization. It is thought an artificial pathogen wiped them out. DNA testing suggests a common ancestor to all these fungal growths from around 350 million years ago.

  • Some planets have the remains of a much older interstellar civilization not known to the Galaxy. There's even more mysterious objects floating out in space.

    Homeworld: Fragtun in the Dartwil System
    Average Lifespan: 75 EYears
    Total Population: 117 Million
    The Zarni are a race of humanoids with hooved feet. Their bodies are completely covered with short coarse fur that comes in a variety of colors and patterns. Their hands only have two fingers and a thumb that ends in a hardened nail. All three digits are opposable to each other. Their ears are long and leaf shaped, sitting on the top of their head. They can turn these 180 degrees in any direction. While they have large eyes allowing for them to see in a variety of conditions, they can't see the color blue.

    The Vusinor first contacted them at the dawn of the civilization's Iron Age, were confused for a mythical race of another plane of existence, and had their technology explained away as magic, and are avoided by the Zarni. This works just fine for the Vusinor, who are only on the world to research the gigantic structures from an earlier civilization. These superficially relate to structures found in other parts of the Galaxy.


    Homeworld: Ablabok in the Siltauxen system
    Average Lifespan: 1200 EYears
    Total Population: 93 Million
    The homeworld of the Maenor is a 'Snowball World'. Glaciers exist everywhere on land and covers oceans except near the equator. All land life is extinct. The Maenor evolved on land while the planet was slowly freezing, and are able to breath both the seawater and the specific atmosphere of their world, which is extraordinarily rare in the Galaxy. Most ocean based civilizations can't breath in an atmosphere at all, and unable to have access to fire, are stuck in the stone age forever.

    The Vusinor have successfully contacted this alien race, and are currently studying their development. Interestingly this is one of the few primitive alien races that didn't attempt to worship the Vusinor as gods the moment contact was made. The Maenor's religious views oddly accounts for mortal visitors from above the ice.


    Homeworld: Gla'ak in the Dulgiz system
    Average Lifespan: 125 EYears
    Total Population: 2.4 Billion
    Race of humanoids, evolved from rodent type mammals. They are currently in the middle of destroying their planet. Two competing super powers have been at war with each other for decades, and have irradiated close to 85% of the planet's surface, and neither side will stop until the other is fully eradiacted.

    The Vusinor have attempted to intervene in this war, only to be seen as gods first, then once that was explained away, got their ships targeted in orbit by both nations. It isn't that a primitive nuclear weapon can harm a Vusinor Ship, but it still annoyed them. The Vusinor instead went to the few neutral countries that weren't completely destroyed and took several hundred thousand of the locals, transporting them to the neighboring Balgiz system. In this system there is a world that was inhabited by a civilization around nine million years ago, but an Ice Age wiped them out. The Vusinor hope that the Ulharn will repopulate this planet, and hopefully avoid destroying themselves this time.


    Homeworld: Ulsai in the Uatreme system
    Average Lifespan: 105 EYears
    Total Population: 765 Million
    Species with an Avian body plan, evolved from Saurian type animals. They are permanently slouched over, with a large tail balancing their movements. They have long legs and their arms evolved grasping hands. Brialliant feathers cover their entire body so they have no need for clothing. They are highly intelligent and prove that you don't always need a humanoid body plan to evolve higher intelligence, and is of interest to the Vusinor because of this. Their civilization is currently around the Bronze age in development.

    Regalti scientists were hired by the Vusinor to establish contact with this alien species. The Kerasalt reacted with curiosity, and then took joy into annoying/impressing the Regalti to get their skin color to change. Also of note is that this is another civilization that didn't see an alien species as gods upon meeting them. The Kerasalt have legends of a mythical race of messengers that stand upright like the Regalti do.

    Points of Interest

    Firion Nebula

    Human Knowledge of the Firion Cloud can be found here: Orion Molecular Cloud Complex

    The largest star forming region in the Cairn Sector, and the largest star forming region for over a thousand light-years in every direction. It has over 100,000 M of protostars and material, forming a bright beacon in space, and is used as a landmark, forming the very center of what the Galactic Council designated as the Cairn Sector. Even locally, the nebula is a bright marker in the sky for thousands of intelligent species for thousands of light-years, and is often one of their most studied, and sometimes worshipped stellar objects.

    The Vusinor call it Firion. One of their early civilizations had a tale called the "Youiteln Firie" which in their modern language translates to "Epic of Firion". It was the tale of their very first hero, and the most important character in their mythologies outside of the gods. Firion challenged the cruel Gods, who played with the Vusinor for their own petty gains. The Gods struck down Firion, but not before he inspired the rest of his people to rise up and chase the Gods back to the stars to never return.

    The Maorians call it Actonqua. Their earliest civilizations believed it to be the source of all air in the universe, where the purest form of this element could be found. They viewed each of the brightest Nebula as heavens, having around 12 total, and Actonqua was the holiest and highest heaven they could aspire to reach after death.

    The Regalti call it Sepalla. Their mythologies say that is is a piece of the cosmic ocean (the Milky Way), that the Gods kept separate after creation. They are to use it to recreate Collena and the rest of the universe after it gets destroyed by the great darkness, after the end of all things.

    Star Whales

    Wandering around the cosmic void within the Firion Nebula are large creatures with variable shapes. They can sometimes be as large as a rocky planet, but are usually no more than 50-100km across. These Star Whales are quite rare in the Milky Way Galaxy, and only a dozen or so pods are known to exist. They are much more common in Andromeda and is thought they originated there. They feed on mainly heavier elements found in the remains of supernova. They tend to avoid feeding on fully formed planets to avoid being torn apart by the gravity.

    Cloud of Darkness

    Image used as example of a dark nebula
    A rather small Dark Nebula, around 10 light-years in diameter. Designated LDN 1622 on Earth. Unreliable Earth measurements place it anywhere from 500 to 1500 light-years away from them, but It sits about 100 light-years from the Regalti in the Delvi System, and affects the ability of the Regalti to visually observe a small portion of the sky. It is rather unimportant to the Vusinor and Maorians and is often a footnote in records describing much larger and more impressive dark nebula.

    The legends surrounding this Nebula in early Regalti civilizations were varied. One civilization used it as a representation of the Void, ever present, opposite to everything else, but currently losing the war of the cosmos. It wasn't an aspect of one of their gods. It was literally nothing. Another civilization believed it was here that all gods and life came from and filled the world with life. Others believe that it was a portal to hell itself, a dark, cold place where evil things dwelt.

    One other thing of note about this nebula is that a monolithic cube of smooth black metal, measuring about 50km across was discovered here by the Vusinor, which was eventually transported in orbit around their home system.


    Called 'Betelgeuse' by humans, 'Iruin' by Maorians, and 'Zika' by Vusinor, Ventar is a large, bright star. From the perspective of Earth, it appears as a red hypergiant that will explode any day now. From the perspective of the Regalti, it is easily the brightest star in the sky outside their system, and is the second brightest star in the sky to the Maorians and Vusinor outside of their systems. Ventar sits on the outer edge of the Cairn Sector, being almost 700 light years from the center. It is only around 150 Light-years from the Regalti's system.

    Ventar literally translates to "All and One" or "One and All", and is also Regalti word for God, and several early civilizations worshiped the star as either their only deity or one of their most important deities because of its red color. The Regalti worshiped it even over their own star, Fevalter, to be nothing more than the son/daughter of God or a minor God. Other civilizations claimed Fevalter was more important because she was close and gave them warmth while Ventar was distant. It led to numerous holy wars in the early history of the Regalti.

    Early Regalti also tracked Ventar's strange and seemingly random periods of variable brightness, creating long cycles that they integrated into their calendars.
