Arthur's eyes scanned the tablet screen with growing fascination. The history of this universe unfolded before him like a tale from another world which, to his understanding, it was. The timeline of humanity's progress diverged sharply from what he remembered.

The discovery of advanced propulsion systems, humanity's expansion across multiple planets, and the formation of the United Federation of Earth (UFE) painted a picture of ambition and unity. Yet there was a subtle undercurrent of war, the struggle for survival against monstrous creatures, and the rise of the ECHOs as humanity's elite guardians.

He marveled at the ingenuity but also felt a pang of unease. "How did I end up here? And why does everything feel so... different? This is totally different from what happened on Earth, so it must be a parallel world." Arthur's thoughts churned until a sharp knock on his door interrupted him.

James' voice came through. "Arthur, come with me. There's something we need to discuss with you."

Arthur placed the tablet down and followed James through the mining station's winding corridors. They entered a room with stark white walls, a metal table, and two chairs facing each other. James gestured for Arthur to sit.

"Wait here," James said before stepping out.

The silence in the room was unsettling, but Arthur didn't have to wait long. The door opened, and one of the ECHOs who had helped to slay the behemoths entered. Without his helmet,

Arthur could see the man clearly. He was tall, with jet-black hair styled neatly back and piercing blue eyes that seemed to assess everything in an instant. His face was sharp, with high cheekbones and a strong jawline, giving him an air of authority and precision. The dark armor he wore made his presence even more commanding.

The man sat down across from Arthur and leaned slightly forward. His gaze was direct, almost unnervingly so.

"Arthur, was it?" he asked, his voice calm but firm.

Arthur nodded. "Yes. And you are?"

The man didn't answer. Instead, he began his line of questioning. "Where are you from?"

Arthur frowned slightly but answered truthfully. "I told James already. I'm from Earth."

The ECHO's eyes narrowed. "Explain how you arrived here."

Arthur recounted his arrival, his struggle to understand this world, and his confusion over its differences. The ECHO listened intently, only interrupting occasionally for clarification. Then he shifted topics.

"What was the history of your Earth like?" he asked, his tone still calm but with a sharper edge of curiosity.

Arthur hesitated but decided to answer. As he spoke, describing the wars, technological advancements, and societal shifts of his Earth, he noticed the ECHO's expression subtly change. A flicker of surprise crossed his face before he quickly masked it.

When Arthur finished, the ECHO leaned back in his chair and exhaled. "So, not only are you from the past but also from a parallel dimension."

Arthur blinked. "You're... not surprised?"

"I've seen stranger things," the ECHO replied cryptically. He leaned forward again. "How did you become this strong?"

Arthur had anticipated this question and prepared a response, a mix of truth and omission. "I already had this power when I arrived on this planet," he said. Technically, it was true, though he carefully avoided mentioning the nature of his powers, adaptability and evolution.

The ECHO studied him for a long moment before standing abruptly. "That will be all for now." He walked to the door and stepped out. Arthur could hear faint murmurs outside.

…

Outside the Room

James stood beside a man in front of a holographic console. The man's fingers danced over the interface, analyzing Arthur's vitals, voice patterns, and responses.

Unauthorized duplication: this tale has been taken without consent. Report sightings.

"Is he telling the truth?" James asked.

The analyst nodded. "Every word. There's no indication of deception."

James' brows furrowed. "It doesn't make sense. How could he suddenly gain this much power? Still, if he's not lying, I have no reason to doubt him for now."

He turned to a nearby soldier. "Guide Arthur back to his room. I'll meet with the ECHOs to decide what to do."

…

The soldier entered the room where Arthur was being interrogated "You're free to go. I'll escort you back to your quarters. If you need anything, you can use the tablet provided to you."

Arthur thanked the soldier and returned to his room. Once inside, he resumed his exploration of the UFE's database. He delved into the structure of the government, learning about its intricate hierarchy and the power held by the various parties.

The ECHOs intrigued him most, their origins shrouded in secrecy but their capabilities revered across the galaxy.

…

Meanwhile, in a secure briefing room, James sat with the two ECHO elites. One of them, still armored, spoke first. "Arthur's situation is unique. We should bring him with us to Solace Prime, and ask the admiral what to do with him. He'll know what to do."

James nodded reluctantly. "I don't have the authority to handle something of this scale. Fine. We'll send him with you."

The ECHO nodded. "We leave tomorrow morning."

…

That evening, another soldier knocked on Arthur's door. "You've been scheduled to leave with the ECHO squad tomorrow morning. Pack your belongings and be ready by sunrise."

Arthur leaned against the doorway, digesting the news. "Where am I going?"

The soldier hesitated. "To Solace Prime. Beyond that, I don't know."

Arthur thanked him and closed the door. Sitting on the edge of his bed, he thought about what lay ahead. "I'm being pulled deeper into this world. Maybe they will have answers... or more questions."

The rest of the evening, Arthur immersed himself in learning about the Epsilon-class warships the Space station Solace Prime and their capabilities.

The sleek, 2-kilometer-long vessels were marvels of engineering, and he couldn't help but feel both awe and apprehension about what awaited him.

…

The next morning, Arthur met James at the landing platform. The commander extended a hand. "Good luck out there. Whatever your path is, I hope it leads to answers to your questions."

Arthur shook his hand firmly. "Thanks for bearing with me. I'll do my best."

The shuttle's hatch opened, and Arthur boarded. As it ascended, the mining station grew smaller until it disappeared entirely. When the Epsilon-class warship came into view, Arthur was amazed. Its sleek, obsidian hull stretched endlessly, bristling with weapons and exuding an aura of invincibility.

Inside, the ship's interior was a seamless blend of functionality and luxury. Soldiers moved with purpose, and the corridors glowed with a soft, ambient light. A soldier guided Arthur to his quarters, a modest but well-equipped room.

The ship launched smoothly, breaking through the atmosphere and into the void of space. Arthur watched from a viewport as the planet shrank into a distant sphere. Moments later, the ship accelerated, and a swirling vortex of light signaled their entry into a wormhole.

…

Exiting the wormhole, Arthur's jaw dropped as the Dreadnought-class space station came into view. The colossal structure dwarfed the warship, its size comparable to Earth's moon. Massive docking bays hummed with activity, and the station's surface glinted with lights and weaponry.

The warship docked seamlessly, and Arthur followed a soldier to another shuttle. His thoughts raced as they moved through the station's labyrinthine interior.

'I don't know where this path leads, but for now, it's the best option I have,' he thought, steeling himself for whatever lay ahead.

…

The shuttle hummed softly as it carried Arthur deeper into the heart of Solace Prime. Through the viewport, he caught glimpses of the station's immense interior, sprawling cities encased in transparent domes, towering spires that seemed to touch the stars, and labyrinthine industrial sectors alive with the flicker of automated systems and the bustle of countless personnel.

"It's amazing how far humanity has reached," Arthur muttered to himself, awe-stricken by the sheer scale of the station. It wasn't just a hub of military and scientific operations, it was a self-sustaining megastructure.

The soldier escorting him glanced back. "First time seeing something like this?"

Arthur nodded. "Yeah. Hard to believe people built this."

The soldier chuckled. "The UFE's pride and joy. Solace Prime is humanity's fortress against it's enemies. You'll get used to it."

The shuttle docked at a sleek terminal, and Arthur was guided through the station's security checkpoints. As he walked, he noticed the diversity of people, humans of every origin and even a few alien species, their forms and features alien yet oddly humanoid.

The air was filled with the low hum of activity, punctuated by distant announcements and the rhythmic march of soldiers.

Finally, they arrived at a chamber with a vast, arched ceiling and walls adorned with holographic maps of the galaxy. At the center stood a circular table, where several figures were already gathered.

Arthur's escort saluted and stepped aside as one of the ECHO elites approached. This time, both were without their helmets, revealing another striking figure, a woman with short, silver hair and piercing amber eyes. She exuded an aura of sharp intellect and calm authority.

"Arthur," she began, her voice measured and deliberate. "Welcome to Solace Prime."
