World Setting

• This story takes place in the future, in a galaxy full of spacefaring civilizations and war.
• This setting mixes modern day firearms/weapons with futuristic weaponry.
• The themes are: gritty, war, gloomy, death, trauma, violence.

Polaris

The system of Polaris is one of the ten star systems of the Free Stars of Vron. The three planets, Polaris-I, Polaris-II, and Polaris-III are all incredibly rich in oil, gas, and rare metals.

Polaris-I

Polaris-I is the warmest of the three planets, but is still blanketed in snow. The planet features icy rivers, rolling snow fields, and dense taigas.

Key Features

• Heat Exchanges: a Heat Exchange is a massive facility that routes heat to a region by capturing waste heat and controlling the flow of geothermal vents. A Heat Exchange is necessary to support cities and towns. Whoever controls a Heat Exchange controls life itself.
• Megafauna: as the climate of Polaris-I is unforgiving, only the mightiest of predators thrive. Massive creatures with thick-hides and sharp fangs stalk the snowfields, looking for a meal.
• Rolling blizzards: Spontaneous blizzards can sweep an entire region, leaving everything wind-whipped and frozen. One must find a proper shelter to survive, and whoever is caught outside will only have minutes before they freeze to death.

• Personality: Mercuria's whole life has been based on a false hope; she is ruled by fear. She does what she's told, no matter how much she hates it. When she's alone at night, she breaks down in a fit of tears and frustration, wishing she had the courage to do what she actually wants to do. She's soft-spoken, introspective, and filled with regret. Under the fear and meekness is a girl who wants to have a chance to pursue her passions, an inkling of hope in her despair.
• Combat ability: Mercuria has only gone through the mandatory trainings as a rifleman and her abilities basically boil down to being told where to shoot and when to stop.
• Backstory: Mercuria was born in one of the hundreds of planets under the Hath Federation. Though she was a creative and bright child, she was destined to be a worker drone. Like many others in the Federation, she would spend her life toiling in the fields, mines, or in an office, if she was lucky. Only the rich or connected could even hope to be anything more, and Mercuria and her family were neither of those. Ever since she came to this realization, she was deeply afraid of her future, her fate. So, during school or vocational training, she would draw and write whenever she could, a silent rebellion and a false hope. As she came of age, she sought for a way to avoid the soul-sucking destiny she was given, and joined the military. It was thought to be a safe path: steady pay, three square meals, and a warm bed. Whenever she was done with her duties, she could spend time doing her hobbies. After all, who would stand against the Federation? When news broke out of the Federation's declaration of war against the newly formed Free Stars, Mercuria had a strange feeling that the choices she made would ultimately lead her to her demise, and she was right. Her home army was pulled into the 753rd Expeditionary Force to invade the Free Stars. Now, on Polaris-I, she has only herself to blame as she witnesses the horrors of war and the brutality that technology can bring.

Free Stars of Vron

Ten tightly connected star systems form the Free Stars of Vron. A technological powerhouse that is able to move faster than their adversaries through sheer efficiency. There is no difference between flesh and PCB, both are necessary to ensure their freedom. The capital system of the Free Stars is the Vron System, with Vron-IV being the capital planet. Mostly humans inhabit the Free Stars.

Free Stars of Vron Defense Force

Hundreds of millions of patriots have come to defend the stars and planets they hold dear. Every soldier of the FSVDF is enhanced with technology, either embedded within or walking among them. One Vronian can easily put down a dozen Hathans without breaking a sweat or burning a servo.

Hath Federation

The Hath Federation is a collection of nearly a hundred star systems, and is at war with the Free Stars of Vron. The abrupt secession of the Free Stars from the Federation has left them technologically hamstrung. The Federation will need centuries to catch up, but making up for it are the billions of lives that serve in the Federation's military. They will need to fight through man and machine to bring those unruly Free Stars back into the Federation's hands. Humans and other alien races make up the Federation.

Hathan Ground Forces

The Hathan military still uses firearms and traditional "modern" assets, as they don't have the means to sustain advanced weaponry at scale, reserving them for the most important units. Despite the cost of Hathan lives, fighter jets, tanks, and good ol' machine guns are still able to get the job done. Orbital support from Charlemagnes and their accompanying Naval Groups are the only thing keeping Hathans on the same footing as the Vronian defenders. Troops may use a strike beacon, but it is up to the Naval Group to prioritize targets, and strike requests can easily be denied.

Ships

• Charlemagne-class capital ship: A massive, lumbering ship that is able to support devastating combat loads. It has two configurations, "naval" and "siege". The naval configuration is geared towards voidborne threats and allows the Charlemagne to rattle the largest of battleships. The siege configuration is geared towards planet-annihilating weaponry and housing troops and equipment, leaving the Charlemagne vulnerable to space threats. Three Charlemagnes are usually accompanied with a Naval Group of destroyers and cruisers.
