Theras is the second planet in the Aneros System. It is a temperate superhabitable terra home to the widespread Bilphon species in the Kardesh Galaxy of the vast Crown Cluster. Theras is the cultural capital of the Arcturium Civlization.

## **Overview**

Theras is one of the most important worlds in the Kardesh Galaxy's entire history, as it served as the birthplace of the Bilphon species, which would quickly become one of the most prominent species across the Kardesh Galaxy. Thanks to this, Theras is held in extremely high regard in almost all Bilphon cultures, serving as the spiritual homeland of all who bare the title of Bilphonkind. Because of its significance in Bilphon history, Theras is the single most generally shared thing in Bilphon culture throughout the Kardesh Galaxy, and as a result, it is by far the most closely guarded world for all Bilphons.

Despite how much it is beloved by Bilphons today, the aforementioned species did not seem to worry about the overall care of the planet, allowing artificial climate change to run rampant for hundreds of years, deforesting many life-filled forests, causing countless species to go extinct, and pushing the planet's resources to the very brink. Despite this, Bilphonis would eventually be able to undo the damage done by their predecessors, and they would do all possible to keep Theras as it was millennia ago, even slowing the natural process of continental shifting.

Due to the population crash of most of the main cities, Theras is much greener and more hospitable than it was in previous millenia. Every structure, residence, and city must have little plants or grass growing around them and in their lawns. There were even a few cities that were cut off from the rest of the world and abandoned.

Theras is currently a paradisaical housing planet, one of the top tourist destinations in the Kardesh Galaxy, and busy trading hub. A full ten percent of the planet is covered in large mega-cities designed to have as little impact on the natural environment as possible, with the rest serving as nature preserves for a large array of life, including cloned versions of animals made extinct by civilization in the past.

## **Moon System**

Theras has a single selenic moon named Lutari, which itself has been preserved for cultural purposes. It has a small population of around seven billion inhabitants, located in various large biodomes and metropolises protected the dangers of Lutari.

In the past, Theras used to have another moon named Olenor, but it along with the old Lutari got pulled into Theras, they together formed the moon of Lutari as it is today.

## **Climate**

The climate of Theras is one of the most diverse in the entire Aneros System. Its environment varies depending on which climate you're in, with some parts hot enough to create boiling deserts and others frigid enough to create mazes of glaciers. Each region of Theras has a unique biosphere able to support a variety of flora and fauna.

Its orbital position within the habitable zone of the star Aneros allows for carbon-based life to flourish across the planet's whole surface.

The planet's people also keep this environment under check by employing artificial climate generators to maintain a desirable temperature and climate in various sections of the world. These climate generators have also made Theras more hospitable to life than it was previously.

## **Bilphon impact on Theras**

### **Negative Effects**

The rapid advancement of the Bilphon species through typical technological stages, such as the discovery of electricity and the invention of industrialism, would have an impact on the wider world around them, as artificial carbon dioxide emissions would cause the global climate and temperature to rise artificially. The planet's ice caps melted as a result, threatening the life that lived there and raising sea levels.

Along with the environment, the planet's natural resources would be nearly depleted due to the ever-increasing need of a growing population. Much of the planet's native forest regions would be completely devastated as the trees that make them up would be demolished for the countless resources that they require. The majority of Theras' natural oil and uranium reserves are also located there.

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 Bilphons caused, as many thousands of tons of plastic from the old times still remain in the ocean to this day.

Theras would also be given countless artificial satellites by Bilphons, covering the planet's orbit with communication, weather, and mapping satellites, along with orbital telescopes. Though these would grant Bilphons a much more advanced 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 Bilphon 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 Bilphons made a habit of just killing them outright to have access to resources exclusive to them such as ivory.

### **Positive Effects**

Bilphons have had a significant positive impact on planet Theras, the most notable of which being the undoing of damage caused by them. As the species progressed to type one, surplus carbon dioxide emissions would be gradually removed, recreating a more natural climate cycle on the globe.

Not only that, but many of the extinct animals wiped off by Bilphons would be brought back to life through cloning technology. The Irridalli, Salatrians, and Quirot Fish are among many of them.. Other species that had been long dead by the time of Bilphon evolution were also brought back to life.

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 Bilphon, 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 Bilphon life on the world. Any asteroid that poses a threat to the Theras and the life that inhabits it are destroyed by Bilphons before it even crosses a thousand kilometers in the planet's orbit. As well, Thears has remained untouched by any large scale intragalactic or intergalactic conflict involving the wider Bilphon species, as its location is often hidden from other intelligent species.

## **History**

### **Formation**

Theras formed from the planetary accretion disk created from the formation of its parent star, Aneros, in 4,750,000,000 BCE. As it formed, the planet was a hot hell world completely covered in massive fields of molten lava and magma. However in 4,600,000,000 BCE, an ancient planet around six thousand kilometers in diameter nicknamed Olenor collided with Theras, shattering the former and causing massive amounts of debris to be put in orbit around Theras. This orbital debris would eventually coalesce and form two major moons named Lutari and Indar respectively. This event also caused the planet to tilt on its axis about twenty degrees, causing the planet to experience four distinct seasons.

Theras would enjoy the company of two moons for several millions of years, however in 4,490,000,000 BCE, the smaller of the two moons, Indar, began to have its orbit around the planet slowed by its sister-moon Lutari, 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 Theras into a hot oceanic planet. 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 Theras entirely.

### **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 Aeros Explosion in around 575,000,000 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 Aeros Extinction caused more then 42% of all life on the planet to be eradicated by massive volcanic forces, turning the entire landscape of the supercontinent into a volcanic ocean, killing all life that inhabited it.

However, one of the few remaining families of fauna known as the Terefrogian would begin to rise from the ashes of the world, ultimately evolving into what would become to be species of massive amphibians known as Gigaphibians in 245,000,000 BCE. Gigaphibians 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 seventy-five kilometers in diameter collided with the planet, wiping out all known forms of Gigaphibians.

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 Theras. 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.

And like what would happen with the amphibians, reptiles would rise from the ashes and take their place as the dominant lifeforms of the planet, existing on all landmasses of Theras.
