Earth (also known as GaiaSol Prime, and Sol III) is the third planet in the Sol System and the homeworld of Humanity. It is also the first natural known Me-Class world to Humanity. Earth has one natural satellite, Luna. Earth is most associated with the United Federation of Star Systems as it is the birthplace of Humanity and the administrative capital of the UFSS. The planet functions as the location of several large Bureaus in the Confederacy of Borealis, but it is not one of the official capitals. Even so, Earth is one of the most important worlds in the local universe's entire history, as it served as the birthplace of the human species, which would quickly become one of the most prominent species across the local cosmos. Thanks to this, Earth is held in extremely high regard in almost all human cultures, serving as the spiritual homeland of all who bare the title of Humankind. Due to its importance in human history, Earth stands as the single most universally shared object in human culture across the Local Universe, and as a result, is by far the most guarded world to humanity as a whole.

Despite how much it is beloved by humans today, the aforementioned species did not seem to worry about the overall care of the planet, letting artificial climate change run rampant throughout hundreds of years, deforesting many life filled forests, causing countless species to go extinct, and pushing the planet's resources to the very brink. But despite all this, humanity would manage to reverse the damage done by their forefathers with time, and they would do all that they could to keep Earth as it was from humanity's beginnings, even halting the natural process of continental shifting.

As of 100,000 CE, the Earth has been through countless events and has many experiments conducted on her. Earth is currently a paradisaical housing planet, one of the top tourist destinations in the Milky Way, and busy trading hub. Many green megacities can be observed from orbit. Some megacities even reside in the vast oceans.

Most farming on Earth is completed by massive farming towers built in places where conditions were hostile in the past. These farms comprise of up to 32% of the food income on Earth. About 6% of the crops come from large floating farms on the oceans, which are powered hydroponically. The remaining 62% of the food comes from imports.

The Earth is much greener than it was back in the earlier ages thanks to the population crash and subsequent ruralization of most of the large cities. Each building, home, and megacity is required to have small plants or grass growing by them as well as in their lawns. There were even a few cities that were closed off and abandoned.

Most of the energy on Earth comes from clean, renewable energy sources such as solar and wind, as well as newer forms of nuclear fusion that are clean and safe for the environment. A tiny fraction of the energy is from geothermal processes in the Earth's mantle and outer core, while the rest come from buildings themselves.

Throughout the planet's history, countless conflicts were waged in its borders. These wars ranged in size from a single area of land, to engulfing all of Earth and her people. The three respective conflicts that fell under the ladder category were known by the local populace as the first, second and third World Wars, with the third of which almost resulting in the extinction of the human species.


The planet currently houses seven continents, North America, South America, Europe, Asia, Africa, Australia and, Antarctica, Each of these continents holds a population of trillions of individuals, larger then entire colony worlds. Separating these continents are five distinct oceans known as the Atlantic, Pacific, Indian, Arctic and Southern Oceans respectively.

Across these continents are many different landscapes such as forests, plains, wetlands, deserts, tundras, badlands and so on. Thanks to this extremely varied geography, Earth is rather famous for the geodiversity of its respective landmasses.


Orbital view of Africa.

Africa: Overview

Africa is Earth's second largest continent, as well as Humans home continent. The Geography of Africa was once mainly Grasslands and Deserts, but is now mainly a huge Ecumenopolis. The Northern region of the continent is one huge desert, known as the Sahara Desert. The central region was, before urbanization rain forests and savannah, and the southern was temperate forests.

By the 200th Millennium, central Africa is the only area that seems remotely as it was in the year 1 CE. The rest is almost as if it had turned into an Mini-Ecumenopolis.

"There is no probability, that any other detached body of land, of nearly equal extent, will ever be found in a more southern latitude; the name Terra Australis, will, therefore, remain descriptive of the geographical importance of this country."-Matthew Flinders

Australia: Overview

Orbital view of Australia.

Australia is the seventh-largest continent on planet Earth. Australia is one of the hottest continents of planet Earth, second only to the continent of Africa, and is also currently one of the most populace. Its original geography was primarily compressed of massive deserts spanning hundreds of thousands of kilometres in length, along with massive fertile plains prime for farmland. However in 2,100 CE, the native humans began to urbanize all landmass on the mainland continent, causing all of the continent to become one massive city and turning it into a miniature Ecumenopolis, this continent-wide city would be known as: "Terra Australis," the original title given to the continent by European explores. Thanks to this urbanization, Australia became one of the most populace continents of the planet, even though it originally stood as one of the least hospitable continents to humans.

Before the continent was completely urbanized, it had one of the most diverse forms of flora and fauna to inhabit its surface, and it also stood as the last bastion of the so-called: "Mega Fauna" of Earth, massive mammals that once dominated the whole of the planet. These aforementioned species would be spared the destruction they would surely face during the construction of Terra Australis thanks to floating refuges in the Pacific Ocean, along with the species being sent to extra-planetary colony worlds that can sustain them.

A controversial subject throughout most of the continent's inhabited history is exactly how large the Australian continent is, and how many landmasses are apart of it. This confusion has persisted for thousands of years, with many including areas like New Zealand, and some of the Indonesian Isles as part of a continent known as: "Oceania."  However, the currently accepted definition of the Australian continent includes Mainland Australia, the island of Tasmania, and the island of New Guinea, and the Melanesian Isles. New Zealand and the Polynesian Isles were defined to be apart of the: "Zelandia" continent.

Australia: Landscape

Before being urbanized, Mainland Australia's terrain mainly consisted of massive arid deserts in the westernmost points of the continent, dry plains towards the center of the landmass, and tropical in the easternmost point.

Antarctica: Overview

Orbital view of Antarctica.

Antarctica is is the fifth-largest continent in the world and is also the coldest continent of planet Earth's ten continents, with an average temperature of negative sixty degrees Celsius, and a geography of massive broken ice caps and large snowy mountain ranges. It is located at the absolute south pole of the planet, causing the extreme temperature seen. Despite the cold however, Antarctica has a large population of around fifty billion individuals, mostly clustered in the large coastal cities lined all across the continent's shoreline.

Though it was not always the cold landmass we see today. Originally, it was a temperate land with massive tropical forests dominating major expanses of the land, inhabited by countless forms of flora and fauna. However as it broke apart from the former super continent it was apart of, it would gradually cool down, ultimately becoming the icy wasteland we see today.

For most of the continent's history it remained uninhabited by any intelligent species, as the extremity of its location prevented the native humans from colonizing it. Along with the natural inhospitable nature of the landmass, the various human nations of Earth collectively agreed to bar any colonization attempt of the continent with the Antarctic Treaty. However later on, as the Earth became more and more over populated, the continent would begin to be colonized by various human nations.

By the 200th Millennium, Antarctica is home to 50 billion people, who were born, and live their lives in the southern continent. They live here via a series of underground tunnels and cities, and surface domed cities that protect them from the worst of the Antarctic cold. Hundreds of major cities are located on the continent, and the major capital of the continent is called Suda Poluso, and is located exactly on the south pole. It is home to some of the most advanced scientific research on Earth.

Antarctica: Landscape

As previously stated, Antarctica is a land of icy tundras, massive snow-capped mountain ranges, and countless small icy islands. At the westernmost point of the continent, facing the west Southern Ocean, lies the Antarctic Peninsula, a chain of bedrock islands that are separated by deep channels.


Earth has one of the most diverse climates in the entire Sol System. Its climate is varied depending on each hemisphere, with areas warm enough to creating boiling deserts, while others are cold enough to create mazes of icebergs. Temperatures also range from being cold enough at the poles to freeze water and warm enough at the equator to fry an egg on a metallic surface. Each region of Earth has a unique biosphere able to support a variety of plant and animal life. 

Earth's overall climate is very temperate, so much so that it's often used as the exact model for a: "temperate" world. Its position in its system allows carbon-based life to flourish across all of the planet's surface, orbiting within a so called: "Habitable Zone" for life of its caliber to exist on.

This climate is also kept in check by the planet's inhabitants, using artificial climate generators in order to keep a desired temperature and climate in the various regions of the planet. These climate generators have also allowed Earth to become more habitable to Earth-life then it was originally.


Being the home world of Humanity, the global population is around 6 trillion currently, far over what the natural holding capacity is. The population numbers exclude the inhabitants of orbital habitats and space cities. Most of the population resides in the dense megacities, which reach far into the atmosphere, while the rest live in parts of reclaimed nature, mostly farming for fun.

Earth is a very diverse world culturally, as it contains thousands of regions, some of which still follow fragmented state borders.


In celebration of Vega becoming Earth's new North Star around the year 14000 CE, a petition went through the terrestrial governments, pleading for a beautification type project, as everyone was obsessed with physical beauty at that time as well as making Earth look elegant in comparison to other worlds. Many asteroids and comets were diverted and eventually crashed into each other in controlled collisions. A few smaller asteroids were placed in orbit to keep the rings from degrading, and trillions of nanites were released to construct the rings. 

As well as breaking apart the asteroids and comets, the nanites were responsible for giving the color of the rings. The nanites then rained down after completing their tasks, forming the most brilliant meteor shower seen on Earth in millennia. The ring system has since remained stable. 

Human impact on Earth

Negative Effects

As the human species rapidly progressed through the typical technological stages, from the discovery of electricity, to the invention of industrialism, it would have an affect on the wider world around them as man-made carbon dioxide emissions would cause the global climate and temperature to artificially rise. This caused many of the planet's icecaps to melt, endangering the life that inhabited them and raising the sea level.

Along with the climate, the planet's natural resources would almost be exhausted to the very limit thanks to the ever-growing population's increasing demand. Much of the planet's native forest lands would be totally destroyed as they would demolish the trees that make up them for the countless resources needed from them. As well as most of Earth's natural oil and uranium reserves.

Non-biodegradable resources, such as plastic, were also left all across the planet's surface, with particular emphasis placed upon the planet's oceans. Thousands of tons of plastic would be left in the oceans, leading to a process known as: "Ocean Acidification," which in layman's terms, turns the ocean into acid, endangering all life on the planet that relies on the ocean. This is by far the most long reaching affect on the planet early humanity caused, as many thousands of tons of plastic from the 21st century still remains in the ocean to this day.

Earth would also be given countless artificial satellites by humanity, covering the planet's orbit with communication, weather, and mapping satellites, along with orbital telescopes. Though these would grant humanity much understanding of the planet they existed on, it had an unattended side effect, as vast amounts of orbital debris would be created throughout the decades that these aforementioned satellites were in orbit around the planet. This threatened to coat the planet in a blanket of debris, preventing the human species from venturing into the wider universe at all. However with time they were able to mitigated the problem.

The increasing urbanization of the world also caused the extinction of countless forms of flora and fauna, as they are unable to exist within an urban environment. Not only that but humans made a habit of just killing them outright to have access to resources exclusive to them such as ivory.

Positive Effects

Humans have also had a profound positive affect on planet Earth, the first and foremost being the reversing of damage done by them. As the species reached the type one stage, they would gradually remove the excess carbon dioxide emissions created during the 21st century, restoring a more natural climate cycle on the planet.

Not only that, but many extinct species destroyed by humans would be brought back from the dead with the use of cloning technologies. These include the Woolly mammoth, the Dodo, and the Thylacine. Countless other families of flora and fauna have also been brought back into the world. Along with those destroyed by humanity, other species that were long dead by the time of human evolution, such as the trilobite and the dinosaurs were also brought back and were given controlled environments for them to flourish.

Many floating sanctuaries have been constructed across the planet's oceans, allowing many species to live in controlled environments free from any natural or otherwise threats against them. Along with sanctuaries on Earth proper, many have been constructed in orbit around the planet, as well as being placed on other colony worlds.

Thanks to most resources used by the populace being extracted by extra-planetary colony worlds now, the resource strained planet has begun to have its natural resources replenished. These include oil fields, precious metals, fresh water sources, and massive forests to inhabit unurbanized environments on the planet.

The protection of the planet itself is a major aspect of human life on the world. Any asteroid that poses a threat to the Earth and the life that inhabits it are destroyed by humanity before it even crosses a thousand kilometres in the planet's orbit. As well, Earth has remained untouched by any large scale intragalactic or intergalactic conflict involving the wider human species, as its location is often hidden from other intelligent species.

Restoring of Earth

The united human nations of Earth began to fully restore planet in 2,125 CE. With fusion energy, they were able to provide Earth and extra-planetary colonies such as Luna and Mars with near infinite energy. Along with fusion energy, the discovery of seismic generators just twenty standard years later allowed humans to have complete control of the planet's natural continental shifting, meaning they could control the movements of continents across the planet, as well as stopping the process of earthquakes that could devastate cities across the surface.

Along with the restoring of the land, they would use climate generators to remove much of the carbon dioxide emissions made by humanity during the 20th and 21st centuries, essentially solving the global warming crisis. Not only that, but using remote drones, they were able to remove the blanket of orbital debris that surrounded the planet.

The final righting of human wrong would be the resurrection of almost all known extinct species of flora and fauna that inhabited the planet throughout the remaining centuries of the 2,000 CE through the use of cloning technologies, creating countless floating sanctuaries on both the planet proper, and in orbit around it, as well as other colony worlds across the galaxy.


After the War of the Decamillenial Transition and the Split of the Confederacy, Earth was left with only one billion inhabitants, mostly the richer who used automation to live and survive. The descendants of those evacuated began to slowly come back, although the majority had made new worlds for themselves, most notably three copies of Earth using Terrashaping. By the year 21,000 CE, Earth's megacities had been repopulated. By 25,000 CE, the population remained steady at 30 billion, with much of the people residing within the megacities. The land on and near them was given time to fallow and regrow.



Planet Earth formed from the planetary accretion disk created from the formation of its parent star, Sol, in 4,540,000,000 BCE. As it formed, the planet was a hot hell world completely covered in massive fields of molten lava and magma. However in 4,500,000,000 BCE, an ancient Sol planet around six thousand kilometres in diameter nicknamed: "Theia" collided with Earth, shattering the former and causing massive amounts of debris to be put in orbit around Earth. This orbital debris would eventually coalesce and form two major moons named Luna and Diana respectively. This event also caused the planet to tilt on its axis about twenty degrees, causing the planet to experience four distinct seasons.

Earth would enjoy the company of two moons for several millions of standard years, however in 4,490,000,000 BCE, the smaller of the two moons, Diana, began to have its orbit around the planet slowed by its sister-moon Luna, and it would begin to drift towards the aforementioned body, eventually colliding with it. The two moons would be ultimately torn apart from this event, and the orbital debris would form a singular large major moon sharing the name of the former largest major moon.

Throughout the remainder of the 4,000,000,000 BCEs, many rocky asteroids filled with water collided with the planet, slowly cooling down the planet and leading to massive amounts of water vapor to enter within the atmosphere and form thick clouds. These aforementioned clouds would begin to create massive amounts of rain to fall from the sky, creating a global ocean and turning the Earth into a hot O-Class world. In the following millions of years, volcanoes began to spew out massive amounts of materiel, forming the landmasses that would soon become the planet's continents, changing the Earth from an O-Class world to an E-Class one.

Evolution of Life

In 3,500,000,000 BCE, life began to appear in the planet's oceans. This life form was a simple single-celled organism feeding off of hydrothermal vents deep within the ocean. However it would slowly begin to replicate itself and evolve into more complex multicellular organisms, ultimately leading to the event known as the: "Cambrian Explosion," in 541,000,000 BCE.

Life would continue to evolve into even more forms of complex life, with life being able to inhabit the lands by 380,000,000 BCE. The planet would be absolutely teeming with life, inhabiting all landmasses on the world. Until' unfortunately, in 252,000,000 BCE, an event known as the: "Permian Extinction," or the: "Great Dying" caused more then 58% of all life on the planet was eradicated by massive volcanic forces, turning the entire landscape of the supercontention into a volcanic ocean, killing all life that inhabited it.

However, one of the few remaining families of fauna known as the: "Proterosuchus," would begin to rise from the ashes of the world, ultimately evolving into what would become to be known as the: "Dinosaurs" in 245,000,000 BCE. Dinosaurs would rule the planet for millions of years, spreading themselves across the whole of the planet. However they too would face destruction when a massive asteroid around eighty-one kilometres in diameter collided with the planet, wiping out all known forms of dinosaur.

And like what would happen with the dinosaurs, mammals would rise from the ashes and take their place as the dominant lifeforms of the planet, existing on all landmasses of Earth. As they continued to propagate themselves, what would become to be known as the: "Primate" would evolve in 55,000,000 BCE. Primates would have the advantage of opposable thumbs, allowing easy manipulation of the environment around them.

Throughout even more millions of years, certain primate species began to evolve to walk upright, eventually becoming completely bipedal in 4,000,000 BCE. Along with the new posture, select primate species began to evolve larger brains, causing them to remember key things about their environment, as well as the manipulation of simple tools by 3,000,000 BCE, and the manipulation of fire in 1,500,000 BCE. And by 200,000 BCE, they learned the first forms of language, causing the evolution of what we would come to know as the intelligent species: "Humans". Though they were not alone on the planet, as another intelligent species known as the: "Neanderthals" inhabited the landmasses with them. However gradually over time, Neanderthals would be fazed out by humans thanks to crossbreeding.

Early Human History

Humans would begin to spread themselves across the whole of the planet, inhabiting all of Earth's continents by the year 10,000 BCE in larger and larger groupings of people. These groupings of people would eventually form the first examples of human society and each would have various sizes of land and technological capabilities. Some Human groups would learn how to plant massive amounts of farmland, allowing for great amounts of food for their respective populace. While others learned how to tame other fauna of their home planet, such as horses, to allow them to travel the land much quicker then they would have been able to do otherwise. And by the year 5,500 BCE, sailing was a common technology of human societies, allowing them to travel across the ocean and visit distant continents.

The usage of metals such as bronze and iron would also become a common practice among human civilizations, allowing them to create much more durable tools and increasing productivity. Unfortunately, what would become to be a common practice among the species, countless conflicts would be waged by various human civilizations for various reasons, though the most common would be the expansion of their respective empires, with several attempting to conquer the entire known world, with the most successful of this time being the Mongol Empire which controlled almost the entirety of the Asia continent.

Long after the fall of the aforementioned empire, the human powers of the Europe and Asia continents were the most powerful forces on the planet, and the European powers had ambitions to conquer the entire world, particularly the nations of England and Spain. In an attempt to open new trade routes to the Asia continent, they would discover the North and South American continents, and the collective continent of Europe would pillage and conquer the New World, commuting horrible atrocities to the native humans that already inhabited the lands. However with time, the two American continents would be able to beat back their European occupiers, becoming independent nations. Afterwards humans would discover and colonize both the Australian and Zelandia continents.

Exploration and colonization of the planet would be one of the chief goals of humanity after the discovery of the Americas, as they believed that the world was made up of massive landmasses. However after areas like the Falklands Isles, and the Polynesian Isles were discovered, it was believed at the time that all that remained of the world were small islands. Unknown to them at the time, there was one more large continent, located at the planet's absolute south pole, and it would finally be discovered by humans in 1,816 CE, and they would name it Antarctica. However thanks to its inhospitable nature, and the current technological capabilities of humans at the time, they were unable to colonize it, and they would remain unable to for many years to come.

After the discovery of electricity in 1,879 CE, humanity began to discover more and more technologies at an extremely fast rate. From industrialism, covering the planet with massive factories. To the early space age, dotting the planet's orbit with countless satellites humans would evolve along the technological stages at an anomalously fast rate. this technological progress would be slingshot in heights after the two respective conflicts that involved almost the whole of the planet, culminating with the discovery of the possible end of the world, that of nuclear weaponry, though they were extremely restrained in their use.
