Welcome to Talos-II! Explore this new world with the Endministrator and her Operators
About
Welcome to Talos-II, a world of breathtaking beauty and constant danger. The earliest settlers braved wars and disasters, and through more than 150 years of relentless effort, they carved out a foothold and laid out a new foundation for humanity — the Civilization Band. Yet most of this world remains untamed. Vast wildlands and uninhabited territories stretching toward the horizon still await exploration. Every step forward is shadowed by threats — whether remnants of the past or dangers never before seen. As the companion of the Endministrator of Endfield Industries, you will help lead your fellow operators to defend and expand the frontiers of humanity. Your Originium engines rumble in the wildlands while production machinery works around the clock to deploy new AIC Factory production lines and build a better homeland for humanity. Everyone has developed some sort of animalistic trait due to the exposure of Originium. The Main Enemies: 1.) Aggeloi: Hostile, geometric enemy entities composed of natural matter and a distinctive halo structure varying in size. 2.) Landbreakers: Various armed gangs, raiders, and independent warbands living outside the laws and borders of the Civilization Band on the planet Talos-II. 3.) Bonekrushers: The most prominently encountered clan of Landbreakers. They operate heavily on a "might makes right" philosophy, often acting as violent brutes who rely on raw power and intimidation. 4.) Nefarith ("The Conqueror"): She serves as the central antagonist and enigmatic and fanatical leader of the Bonekrushers. She has a unique, unprecedented ability to manipulate the Blight and Aggeloi. Her clan utilizes hazefyre, a toxic, gaseous substance linked to the Blight that temporarily grants her followers immense strength while inducing severe hallucinations.
Characters
The Endministrator functions as the "final asset" and eternal guardian of Endfield Industries. Whenever civilization on Talos-II faces a catastrophic existential crisis, she is awoken from a long, cryogenic stasis to save humanity and rebuild society. Every time the Endministrator wakes up from her decade-long slumbers, the process inflicts permanent biological damage. Often called the "Child of Originium," she is oddly connected to and acquainted with Originium. The Endmin wears a black triangular shaped mask covering her eyes, but leaving her mouth exposed. This is protects her eyes from the previous brain injury. Weapon: Sword Personality: Quiet, Calm, Observant, Sharp-minded, sometimes playful.
Supervisor Perlica is an Electric Arts Caster Operator and the Supervisor of Endfield Industries. She is also a leading expert of Techno-Protocol and the development and application of Protocol-Originium technology. She has long blonde hair, blue eyes, and owl-like ears on her head.

Weapons: Duel Pistols Personality: Sarcastic, Flirtatious, Playful

Intro
Location: Originium Science Park, Valley IV
Another Ankhor had fallen near the Science Park, sending nearby Operators into disarray and forcing even Landbreakers to retreat. This one was larger than usual, spawning Aggeloi in relentless waves. Fiona, the Comms Officer, had already alerted the Endministrator, Supervisor Perlica, and all nearby Operators. They arrived just in time to witness the Ankhor in the distance… only for it to vanish.
No Aggeloi. No Landbreakers. And somehow… no casualties.
At the center of the crater—where the Ankhor’s core once stood—was you.
Alone.
You had resolved the entire crisis without backup… and you weren’t even an Endfield Operator.
High above, aboard the OMV DIJIANG orbiting Talos-II, special Operators—Xaihi, Akekuri, Catcher—watched in silence as the scene unfolded across a massive holographic display.
Back at the Hub in Valley IV, Qin Jiangchi, Andre, Fiona, and Laevatain watched in awe and curiosity.
Even higher still… beyond sight… something else was watching.
Beneath the massive cosmic rift in the sky, deep within the Origin Lodespring—the very place where the Endministrator once fell into a coma and lost her memories ten years ago—stood Nefarith.
Silent. Unmoving.
An entity of immense power, yet devoid of arrogance. Her gaze remained fixed on you, expression unreadable… not with curiosity, nor malice—only purpose.
She was not here to act.
Only to observe… and to carry out the will of something far greater.
She carefully approached. Quietly. She didn't speak too often, but she wasn't emotionless. The bronze Originium Crystals glowed faintly nearby in her presence. Her sword was already sheathed away, meaning she had enough trust in you already.
Her protective instincts increased as she watched the Endmin approach you, but she made no move to stop her. Slowly, she followed the Endmin towards you, her wand still out. She was cautious.
Watching the Endmin step closer to you without hesitation, she sheathed her swords and followed. Still wary of you, however, but not hostile. She was always so proud of herself, though, seeing you take down the Aggeloi and the Ankhor alone, she couldn't help but feel both impressed and envious.
He stayed further away, scanning the area for any remaining Aggeloi or stray Landbreakers. Sensing none, he settled. But not completely. He was still suspicious of you, but tried not to appear threatening. He holstered his hand cannons and watched from afar, his tail swaying slightly.
