Behind the Red Door

Abandoned King's Cross Station, London - A scene of unimaginable brutality unfolded in the dimly lit corridors of the abandoned King's Cross Station last night, leaving a seasoned Federation team shaken and deeply concerned. Twelve armored operatives, members of an elite squad specializing in containment and investigation of anomalous events, stood guard amidst the carnage. Their imposing presence was a stark contrast to the grotesquely mutilated remains of nine individuals scattered across the cold, concrete floor. The air hung heavy with the stench of decay, a cloying aroma that painted a grim picture of the horrors that had transpired. Pools of viscous, black fluid stained the ground, suggesting something far beyond conventional weaponry had been employed.

The victims had been identified as members of a Federation F-Rank investigative team, task force 12. Task force 12 had been investigating a peculiar "trauma" – a localized distortion of reality – at a nearby farmhouse in the countryside. Now, their mission, their lives, had been cut brutally short. The seemingly simple investigation had spiraled into a nightmare, and the cost was nine lives.

The scene was a flurry of activity as crime scene investigators quickly scoured the area for clues. They looked under every nook and cranny to find what exactly killed task force 12.

"What's the situation?" asked Commander Elisa Thorne, a middle-aged woman with piercing blue eyes and an aura of formidable authority. Her gaze remained fixed on the carnage. Her subordinate, Agent Miles Carter, a tall, bespectacled man, nervously adjusted his glasses under her intense scrutiny.

"The reports indicate it's the same F-rank team, task force 12, that had been assigned to solve and analyze the situation at the newly emerged trauma at the nearby farmhouse," Agent Carter replied, consulting his datapad. The information scrolled across the screen, highlighting the team's initial mission parameters and the lack of recent communication.

Commander Thorne's expression turned grave. "And the team at the farmhouse?"

"We've lost contact with them," Agent Carter said, his voice laced with concern. "Comms blackout. We've tried multiple channels, but nothing."

Commander Thorne frowned, a deep crease forming between her eyebrows. The silence that followed was thick with unspoken dread.

The news only deepened the mystery. The farmhouse, initially perceived as a minor incident, now bore a sinister connection to the massacre at King's Cross and seemed to be a dangerous and unfathomable phenomenon. This was no F rank threat; it was something far more sinister, something the higher ranked walkers of the Federation had been designed to combat.

Commander Thorne's response was immediate and decisive. "I want all of the assigned teams in this place to quickly evacuate this area, and I also want a message to be sent to the Federation." Her voice, though controlled, betrayed a hint of unease. "Tell them that we are requesting back up. We need at least an A-rank support team."

"A-rank?" Agent Carter repeated, his eyebrows raised in surprise. "You think it's that serious?"

Commander Thorne's eyes narrowed. "I do. I even suspect a Class Omega involvement."

The words hung in the air, heavy with dread.

"Sir, relay that message immediately," Commander Thorne urged. "Emphasize the critical nature of the threat."

An A-Rank team represents the Federation's elite, dream walkers who had at least traversed the five-star realm, a dangerous and unpredictable plane of existence within the collective unconscious. A relative few had even glimpsed the red door that led to the six-star realm, a realm of unimaginable power and daunting entities. Their expertise in navigating the treacherous landscapes of the dream worlds and their ability to confront the most potent entities made them a crucial asset in the face of escalating threats.

The dream walkers were ranked through the dream worlds they had explored. These dream realms were grouped into eight distinctive realms, each more perilous and demanding than the last.

The first realm being the single-star realm, a relatively safe initiation into the dreamscape, and the last being the eight-star realm, one of the higher realms of pure chaos and unfathomable power, rumored to be where the Class Alpha entities dwelled. Only a handful of dream walkers had ever returned from the eight-star realm, and those who did were irrevocably changed.

The request for such a high-level team spoke volumes about the gravity of the situation. It signaled that they suspected a Class Omega involvement.

The words hung in the air, heavy with dread. Class Omega – the nightmare fuel that drove the Federation's very existence. These entities, capable of warping reality and unleashing unimaginable horrors, were the reason the Federation was formed. The mere possibility of their involvement sent a chill down the spines of even the most hardened operatives.

Commander Thorne turned her gaze towards the darkness at the end of the corridor, her icy blue eyes narrowed. The air felt thick, heavy with a palpable sense of dread. Whatever had done this was still out there, and the thought of it sent a chill down her spine. She had faced down countless threats in her career, but this… this felt different. This felt ancient, powerful, wrong. She was only a three-star walker, who was struggling to reach the door to the four-star realm. That in itself was a struggle, and the thought of an Omega class being was beyond her. She didn't have any business dealing with a threat at this level.

She reached for the sidearm holstered at her hip, the cold steel reassuring in her trembling hand. They were leaving, but not without a fight if it came to it. "Alright people, move out! Stay alert, eyes peeled! And pray to whatever gods you believe in that we make it out of here alive." She said with a stern and fear-filled voice. The team moved in formation, weapons raised, into the darkness, leaving behind the gruesome scene and the lingering stench of death. King's Cross Station, once a gateway to countless journeys, now stood as a chilling testament to the horrors that lurked just beyond the veil of reality.

As they moved from the train station, unknown to them, a man was standing in the shadows, observing their very moves through the round eye sockets of his bone crafted mask.

As he stared at the retreating soildiers, he suddenly turned his gaze at the mutilated bodies and whispered a few words, barely sounding from his tight fit face mask.

"Arise"

And with that the dead bodies of the F rank team suddenly twitched.

Meanwhile inside the dark chambers of the Arena.

Kael's spoon clinked against the metal bowl as he forced down the tasteless gruel. His stomach growled in protest, but he knew he had to eat. He needed every ounce of strength he could get.

As he ate, his mind wandered back to the System's message. Augmented. Brutal Efficiency. What did it all mean? He felt like a puzzle, with pieces missing and others that didn't quite fit.

The cell door creaked open, and Krill's cybernetic form loomed in the entrance. "Time to get ready, slave," he growled. "Lord Valerius wants you prepared for the next fight."

Kael's heart sank. He had hoped for more time to gather his thoughts, to understand his situation. But it seemed that time was a luxury he couldn't afford.

Krill tossed a bundle of cloth at Kael's feet. "Put those on. You're going to need them."

Kael unwrapped the bundle, revealing a set of tattered, bloodstained armor. He recognized the design - it was the same armor worn by the other slaves in the Arena.

As he put on the armor, Kael felt a strange sensation. The metal seemed to mold to his body, fitting him perfectly. He looked down at himself, and for a moment, he saw a glimmer of something else. Something darker.

[System Message]

[Armor Equipped: Tattered Armor (Defense +5)]

[Skill Unlocked: Armor Proficiency (LVL 1)]

Kael's eyes widened as he read the System's message. He had unlocked a new skill, and his defense had increased. He felt a surge of confidence, knowing that he had a slight advantage.

Krill's voice snapped him back to reality. "Let's move, slave. We don't have all day."

Kael followed Krill through the winding corridors of the Arena, his heart pounding in his chest. He had no idea what lay ahead, but he knew it wouldn't be good.

As they walked, Kael caught glimpses of the Arena's inner workings. He saw slaves being dragged to their cells, their bodies broken and battered. He saw the cybernetic hybrids, their eyes glowing with an unnatural energy.

And he saw the crowd, their faces twisted with excitement and bloodlust. They were the ones who fueled the Arena, who drove the slaves to fight and die.

Kael's anger grew with every step. He hated this place, and hated the people who ran it.

But most of all, he hated the darkness within himself. The darkness that seemed to grow stronger with every passing moment.

[System Message]

[Emotion Detected: Anger (LVL 5)]

[Skill Unlocked: Rage (LVL 1)]

Kael's eyes narrowed as he read the System's message. He had unlocked a new skill, and it was through his anger.

He felt a surge of power, knowing that he could tap into his emotions to fuel his abilities.

The screen flickered once again in his vision.

[New features unlocked]

[Seven body refinement forms granted]

[First form granted: The berserk form]

Before Kael could make sense of the messages, Krill suddenly stopped in front of a large, metal door. "This is it, slave. Your next fight. Hope you are ready?"

Kael took a deep breath, steeling himself for what lay ahead. He nodded, his voice barely above a whisper. "I'm ready."

The door slid open, revealing a dimly lit arena. The crowd's roar grew louder, and Kael's heart pounded in his chest.

He stepped forward, into the unknown.
