Eithlinn
More actions
Eithlinn is a habitable moon in the Milky Way. The moon is the homeworld of the Dotsk and is capital of Dotskgard. It orbits the gas giant Tuirne. The entirety of the Tuirne system has a population of 145 Quadrillion, making it the most populous system in the Milky Way. Eithlinn is the largest moon orbiting its planet as well as the largest terrestrial object in its system. The moon orbits a Brown Dwarf three astronomical units away, making the tidal heating caused by its proximity to Tuirne its main source of warmth.
Accompanying Eithlinn are over forty other spherical moons. The largest of which are Anamnesis, Mys, and Roid. Eithlinn is about seventy percent as massive as the Earth, while its parent is fifty percent more massive than Jupiter.
History
The planet first formed 9.77 billion years ago around Tuirne. It was likely that its parent was a rogue planet captured by Medb, the Brown Dwarf it orbits almost 11 billion years ago. The planet first gained oceans roughly 6.6 billion years ago and gained life 5.1 billion years in the past. In the long history of the planet, there were far more asteroid strikes due to the large gravity of its parent, hence why the planet took so long to develop life compared to its age.
Multicellular life appeared on the planet 1.1 billion years ago and shortly after started living on the land 900 million years ago. The large amount of volcanic activity on land offered large amounts of nutrients for these life forms, making land a great place for the organisms to live.
The Dotsk
The Dotsk emerged in 120,000 BCE and quickly developed agriculture as there was no ice age to inhibit them like it did with humans in 100,000 CE. From there, they took another five thousand years to develop metallurgy and enter into a bronze age, quickly replaced by an iron age later that millennia. Much like most species, they had tribalistic tendencies and formed their own nations and economies.
The Dotsk had no access to oil on their planet, they used geothermal power for everything. The lack of oil but abundance of volcanism made this an easy choice for them. As they slowly industrialized, they began spreading to every corner of their planet, bringing technology with them. After several wars, they entered a period of globalism in which the economies of their various nations became more and more interconnected. During this same period, they began landing craft on their accompanying moons. With no threat of climate change, due to the irrelevance of sunlight and the lack of oil, the Dotsk were quickly able to form their planet into an ecumenopolis. There were no limits, they had access to the easiest form of power.
Type I
Eithlinn was fully under the control of the Dotsk by 17,000 CE. Around this same time, the whole of the Tuirne system was being colonized and Eithlinn became an ecumenopolis. Their first mega structure was not a Dyson Swarm, like most civilizations, but a massive orbital ring around Tuirne. This ring was made up of the hundreds of asteroids orbiting Tuirne. With this ring they were able to start gas giant lifting the planet to gather large amounts of Helium 3 to power their ever-expanding nation.
Type II
One of the few planetary systems to become Type II without a dyson swarm was Tuirne. With huge arrays of Fusion reactors, they were able to generate the power required to attain Kardeshev II status. Without things such as plants or a home star, they never developed the concept of Dyson Swarms. Instead, they just kept building up their home system. Soon, they had hundreds of rings around their Brown Dwarf, lifting huge quantities of material to build up their civilization. Other planets in the system were moved around Tuirne as it very quickly became the proverbial center of the Dotsk. Over 99% of Dotsk lived within one light-second of their home world.
Contact
Eithlinn and the moons around it remained where the vast majority of Dotsk lived. They continued advancing their own system with little regard for the outside universe. Their own system could support quintillions, so they had no reason to leave. As they remained in place. population growth slowed, but advanced technology made death a rare occurrence, so this mattered little.
When the LaC first contacted the Dotsk in 15,671, they quickly had the Dotsk join as a single-system-state called Dotskgard. The Dotsk were eager to join an interstellar confederacy, it meant that they would have protection and could remain in their one system. Despite being the smallest of the new states, they were instantly one of the most influential. With a population of ten quadrillion at the time, it was easily a large portion of the population of the LaC. Its economy grew considerably as it was able to import materials it needed rather than fuse elements, allowing for the government to life restrictions on population growth that served to prevent overwhelming the reactor array. Very quickly the population grew as several million more O'Neill cylinders and other habitats flooded the space around Tuirne. Eithlinn gained several artificial layers in this time period to make more room for all the new Dotsk.
Blockades
During the War of the Decamillennial Transition, the system was blockaded by The Empyrean, a nation fighting against the Lactean Confederacy. The imports the people relied on were cut off all at once and the infrastructure around Medb to star lift was mostly several millennia old as they did not need to continue extracting metals from it. The local government, which was largely human or influenced by them, issued several mandates to lower the consumption of individuals. After a decade of this, the Dotsk grew weary of these restrictions, many were suffering deficiencies and the LaC military was busy defending human worlds over nonhuman ones. The normally very temperate Dotsk broke and a revolution occurred, causing the Lactean Spring and, later, the Split of the Lactean Confederacy.
Anarchic Period
The Anarchic Period in the Milky Way saw the collapse of The Lactean Confederacy and downturns in most major nations around it. What this period did was end the Blockade and allow the Dotsk to overthrow their leaders. After several coups and a brief civil war, the nation was able to set up a decently stable republic modeled after the original government the planet had before the Lactean Confederacy. With Eithlinn as the capital world of this New Dotsk Republic, called Dotskgard in Xeno after the Neo-Norse word for the nation, the nation broke its habit of isolationism and began sending colony ships to other worlds. Again, the population swelled as resources flowed in from nearby systems the Dotsk easily subjugated with their huge population to draw troops from.
The Confederacy of Borealis
After the formation of the Confederacy of Borealis, the Dotsk, whose total population was exceeding one quintillion, a companion moon of Eithlinn was made into the Financial Capital of the Confederacy. This thrust Tuirne from a comparatively minor world to the center of markets in the Milky Way. When wormhole technology was perfected a millennia later, over twenty ended up leading to the Tuirne system. Currently, many of the largest corporations have offices on Eithlinn or orbiting it. Despite the large amount of wealth circulating in the upper echelons of Dotsk society, the majority end up living average lives apart from the high population.
Physical
Eithlinn has a small magnetic field of its own. This field is just enough to protect it from the cosmic rays that its parent's magnetic field misses. Even so, a lot of radiation is missed, causing most species to be covered in thick layers of dermis filled with pigments to absorb harmful rays.
Oceans water covers the surface of most of the planet. These oceans are mostly a uniform depth except for around land masses. Here, they sharply decrease it depth until hitting land. What land there is on the planet is formed almost entirely from volcanic activity. Every bit of land has a large volcano at its center, spewing large amounts of vital chemicals into the air and ground. Islands that cease volcanic activity somewhat quickly erode away due to the fairly high erosion rate on the moon.
At one point in the moon's history, it was thought that Mys, a companion moon of Eithlinn, was a sub-satellite of Eithlinn as the majority of simulations ran backwards suggest this.
Geography
Most of the planet's original volcanic activity and natural surface has been altered by the Dotsk to suit their needs more, leaving little in the way of natural geography left. The planet has five layers made mostly of material brought in from asteroids orbiting Tuirne. These layers are covered in large amounts of buildings and other infrastructure in edition to large open spaces and parks for the sake of aesthetics. On the poles of the moon are massive radiators that emit large amounts of infrared light, cooling it. Were it not for these radiators, the moon would very quickly heat to the point of killing its inhabitants.
