Archeron

Archeron in Space Engine

Archeron is a Class X habitable planet located in the Archeron System, in the Scutum-Centaurus Arm of the Milky Way Galaxy. Archeron was the home planet of an ancient warfaring reptilian race known as the Sagittari, and for many millennium served as the capital of the Sagittari Slave Empire until its ultimate collapse and occupation by the Trappist Empire.

Archeron formed around 12 billion years ago around its parent red dwarf star, Archeron Prime. After billions of years, Archeron acquired a breathable oxygen-nitrogen atmosphere, settled into a stable orbit, and life evolved on the planet. Among the many forms of exotic alien life, the reptilian Sagittari race would emerge around the year 180,000 B.C.E. The Sagittari would advance slowly, as many factions formed on the surface of Archeron, and millenniums upon millenniums of aggressive tribal warfare would take over the planet, wreaking havoc on the planets biosphere. After around 60 millennia of constant warfare, the Sagittari would unite under one banner and scientific, military, and societal progress would accelerate. The Sagittari soon began expanding around their home system, and being in a rather fertile part of the galaxy, discovered other planets with life, and even some other sentient races.

The Sagittari weren't keen to share resources and planets with other races, and began waging genocidal warfare on numerous other species. They developed bioweapons to cleanse planets and make them suitable for Sagittari colonization. Scientists in the Archeron system conducted brutal experiments on captured POWs to create more bioweapons. Eventually, the prototype for what would become the galaxy-altering "Nano Corusia" pathogen would be created. The Sagittari Slave Empire was created, and slaves were brought to many regions of the empire to labor for many long hours with barely any compensation.

Eventually, after thousands of years of constant labor, oppression, and genocide by their Sagittari overlords, the many enslaved races of the Sagittari Slave Empire began to revolt, and a long series of civil wars between the Sagittari and the races it had oppressed effectively collapsed the empire. After the war ended, Sagittari influence was mitigated to a few systems outside Archeron. The Sagittari Empire was reduced to an interstellar hermit kingdom. The luxurious and advanced lifestyle on Archeron began to collapse, as the Sagittari lost many resources and almost all of its slaves, Sagittari had to begin working to pick up the slack. The government on Archeron and the few remaining systems slowly became more dictatorial and many Sagittari civilians on Archeron became lower class.

In 52,837 B.C.E, the Trappist Empire discovered the remnants of the Sagittari Slave Empire during a routine expansion. The Trappists at first attempted negotiations to incorporate the remnants into their regime, but the Sagittari refused any negotiations. The Trappist Empire chose to invade the remnant hermit kingdom and subjugate the Sagittari. War was declared, and the Trappist starship fleets quickly invaded and occupied several key systems, inflicting huge losses to the Sagittari within a single Earth year. The Sagittari struggled to mobilize their forces and were eventually forced to evacuate all forces to Archeron for a last stand. The Trappists deployed fleets of starships and troops onto Archeron. Despite staggering progress, the Trappists struggled on Archeron due to the Sagittari cities being made of a hyper-resistant metal alloy. Despite this, the Trappists occupied and annexed Archeron after two years of war.

Life on Archeron plummeted rapidly, the Trappists established an occupation government, and every useful Sagittari civilian was enslaved. Sagittari scientists were forced to replicate both their hyper-resistant metal alloy and the "Nano Corusia" pathogen for the empires operations on Nesta. The by-product of the pathogens production infected the planets biosphere and slowly killed off or infected most flora and fauna species on the planet. The Sagittari population of the planet began to plummet, and brutal repression by the Trappist Empire left many more Sagittari to rot in labor camps across the planet. Archerons' skies and atmosphere began to darken and turn purple, as did the oceans, and a mass extinction of much of the planets biosphere had begun. By the end of the occupation and beginning of the Trappist genocide of the Sagittari, only 16% of Archerons biosphere and 3 billion Sagittari remained.

After the genocide of the Sagittari and abandonment of the planet, Archerons biosphere continued to die off, and any Sagittari that survived slowly died off, ending the species after a few more generations. Archeron was unaffected by the 200 Year War, and was left alone for 55,000 years. In that time, 87% of all life on Archeron died, with any remaining survivors being mutated by the pathogen.

## Overview

### Description

Archeron is a Class X "Graveyard" Habitable planet. Much of the planets flora is colored purple, and the Nano Corusia pathogen in the atmosphere has bended the red dwarf stars rays into a dull purple color. Archeron has very little flora and fauna, with many converging on small spaces of life such as islands, mountains, near flowing rivers, and at the poles. As a result, much of the planet is lifeless, where only hardy plants and some animals can effectively survive and adapt. Most creatures have been infected and mutated by the pathogen, and are more deformed and alien than any uninfected creatures. The planet hosts the remains of thousands of once prosperous Sagittari cities, and many Trappist labor camps, facilities, and laboratories constructed during the occupation. The Trappist Empire constructed its headquarters on the planet on an island chain in the planets southern oceans. The Trappist Obelisk, a large communications tower that coordinated the operations on the planet, was constructed on an artificial floating island, and below it, in the abyssal depths, the main laboratories were constructed. These laboratories manufactured the Nano Corusia pathogen en masse for the Trappist Empire.

Despite the low biodiversity and dead zones covering most of the planet, life has adapted and even thrived on some small, isolated areas of Archeron. Life has flourished on certain isolated island chains, mountain ranges, and expansive cave networks, with many species adapting to the mass extinction and evolving to fill in many ecological niches. The oceans aren't completely dead either, as close to the thriving ecosystems, diverse aquatic flora have taken root on the seafloor, drawing in herbivores, which drew in medium sized predators. In the deeper areas of Archerons oceans, gigantic creatures have been rumored to take residence in the open oceans and trenches.
