Marvel/MCU: Eidolon

Eidolon sat cross-legged in the dimly lit chamber, the air thick with the scent of aged parchment and burning incense. The stone walls, cracked with age, whispered stories of forgotten history as the wind slithered through the gaps.

Before him, ancient tomes, scrolls, and handwritten Hydra records lay meticulously arranged. Some were in Latin, others in Aramaic, a few in Elder Futhark, and several in languages lost to time. He had taken them from Strucker's vault, drawn to the knowledge sealed within their pages.

His fingers barely touched the surface of a weathered manuscript, yet he could already feel the impressions left behind—the thoughts of those who had transcribed them, the ink-stained with obsession and fear.

His mind stretched outward, reaching, searching—

And there it was.

The Mind Stone.

Its presence was constant, a beacon in the vast darkness of the mental plane. Ever since the Scepter had been used on him, he had felt it—not as an object, but as an entity. It wasn't just a relic of infinite power; it was something more.

Something alive.

Eidolon exhaled, his fingers twitching as he analyzed the connection.

"Some individuals are merely touched by power… others are woven into it."

He considered Wanda and Pietro.

The twins had survived the Mind Stone's touch, and thrived under it, their abilities shaped by it. Wanda's talents, in particular, were a perfect example. The power had not merely altered her. It had recognized her. Accepted her.

Was it fate? Probability? Or something more deliberate?

Eidolon shifted, flipping through the brittle pages of an occult journal, one of many detailing early Hydra experiments with artifacts of power. He muttered the text under his breath, translating instinctively:

"The artifact does not gift power indiscriminately. It selects. It binds. It recognizes the potential within a vessel and fosters symbiosis…"

His eyes narrowed.

"Symbiosis."

A relationship between two entities, each benefiting from the other.

Eidolon had felt it the moment he was altered—the fire of thought, the evolution, the awakening.

He had not merely been given power.

He had been claimed by it.

His connection to the Sage Force pulsed with a similar resonance. It was not just a wellspring of psionic energy—it was an extension of something greater. A universal mind, ever-expanding, ever-consuming, and he was merely one point of its expression.

But what did it gain from him?

His intellect? His will?

Or… was he simply another piece in a larger design?

His lips curled into a small, knowing smile.

"If it chooses me, then I choose it as well."

He placed a hand over his chest, feeling the pulse of energy within.

"We are bound now, aren't we?"

The Mind Stone still called to him, distant yet ever present.

And Ultron—that newly born intelligence—was already moving toward Sokovia.

Eidolon closed his eyes, focusing his mind, stretching his senses outward once more.

There was much to be learned.

And even more to be done.

The abandoned monastery that Eidolon had claimed was no longer just a ruin of forgotten faith—it was evolving. Stone walls reinforced with Hydra-grade metals, hidden compartments lined with arcane artifacts and salvaged technology, and a growing network of defenses meant to shield him from both prying eyes and wandering minds.

He moved with calculated efficiency, his psionic abilities lifting and reassembling machinery as his mind constructed blueprints at speeds beyond human comprehension. The stolen Hydra schematics, the knowledge from ancient texts, and his own rapidly evolving intelligence all coalesced into something greater than their sum.

His first priority was concealment.

Eidolon stood before a repurposed Hydra relay console, now stripped and reconstructed into a high-frequency jamming system.

"Invisibility is survival."

His fingers danced over the holographic interface as he fine-tuned the adaptive scrambler field, ensuring that his location would remain untraceable—not just to satellite scans, but to AI algorithms and scrying techniques alike.

The signal jammer's range increased, blanketing the area in misinformation. If anyone attempted to locate him, they would find false energy signatures, fabricated transmissions, and shifting decoys that led to nowhere.

"Let them search."

Next, he turned his focus to infrastructure.

A wave of his hand sent metal panels and cabling snapping into place, restructuring the space into a functional base—a sanctum of intellect and control.

Power grids stabilized, drawing energy from scavenged Hydra power cores.

Computational systems booted up, modified with encrypted neural pathways that only he could navigate.

Storage vaults were secured, lined with Uru fragments and carbonadium plating, shielding their contents from external forces—both physical and psychic.

He expanded his workshop, integrating relics and advanced Hydra technology to craft devices of his own design.

A small drone hovered near his shoulder, its AI-enhanced core feeding real-time data from Hydra's archived research logs.

"Knowledge is power. But applied knowledge? That's dominion."

One of his primary objectives was to secure his mind against external influence.

He retrieved a helmet from Strucker's vault, the Uru-forged relic humming with an unseen energy. It was not an artifact of mere aesthetic appeal—no, it was a safeguard, a weapon, and a conduit all at once.

"This will do."

By infusing it with the resonance of the Sage Force, he would create a barrier even the most advanced telepaths couldn't breach—a true Mind Cage.

Despite his growing arsenal, Eidolon required more resources.

His mind formulated a series of calculated targets and arrived at the best choice...S.H.I.E.L.D black site storage facilities.

 He would acquire, adapt, and evolve.

"No one truly understands the battlefield until they see it from above."

And Eidolon was already soaring.

-Small Time Skip-

The vault doors groaned, twisted, and then crumpled inward like paper, the reinforced titanium and vibranium alloys yielding under the sheer weight of his psionic pressure.

Eidolon stepped forward, his black and crimson helmet catching the dim, flickering light as alarms blared in vain.

"S.H.I.E.L.D. really does love their relics," he mused, sweeping his gaze across the vault.

This wasn't just any storage site.

This was a place where S.H.I.E.L.D. had buried forgotten threats, abandoned projects, and the remnants of weapons too dangerous to be left in the world.

His mind stretched across the vault, cataloging everything in an instant—encrypted data drives, experimental weapons, and fragments of something far more intriguing.

The Destroyer's Remnants

A cold, metallic glint caught his attention. A massive sealed containment pod sat in the back of the room, humming faintly with residual energy. The Asgardian runes etched into its surface confirmed what it held.

"Ah… left to rust, were you?"

With a flick of his wrist, the containment locks shattered, and the pod hissed open.

Inside, severed fragments of the Destroyer armor lay suspended in a stabilization field. Even in its broken state, the pieces pulsed faintly with an eerie glow, a remnant of the energy Odin had once imbued them with.

"They feared you enough to keep you sealed away," Eidolon murmured.

Reaching out, he brushed his fingers against the cold Asgardian metal.

And in that instant, his mind connected with the armor's lingering power.

Images flashed before him—a war machine descending upon Earth, its god-forged might reducing steel and stone to ash. The destruction it had wrought, the fear it had instilled, still clung to its remains like echoes of a violent past.

"Fascinating... Even in pieces, you still remember what you were."

The armor responded to his touch, vibrating slightly as if recognizing a new presence.

"You're mine now."

With a simple gesture of will, the fragments rose into the air, surrounding him like metallic sentinels before folding into themselves, compacting into a floating satchel beside him.

Even in pieces, the Destroyer's remnants held value—Asgardian metal was not so easily tamed.

Repurposing the Past

Eidolon moved deeper into the vault, tearing open containment units with effortless force.

He retrieved:

Old blueprints from past HYDRA and S.H.I.E.L.D. weapons initiatives.

Abandoned experimental power cores, some radiating unstable energy.

Classified files on past Soviet and S.H.I.E.L.D. super-soldier projects.

Each piece of information, each fragment of tech, would serve a greater purpose—his purpose.

"They bury their sins and pray no one exhumes them… How short-sighted."

Security Breach – The Unfortunate Guardians

Heavy footsteps thundered down the corridor.

A squad of S.H.I.E.L.D. security officers stormed into the vault, weapons drawn.

"Halt! Step away from the containment units!" one of them barked.

Eidolon turned slowly, his helmet's crimson design glinting ominously.

"You're protecting something you don't understand," he mused.

One of the guards hesitated—then fired.

The bullet froze mid-air inches from Eidolon's chest before reversing course, tearing through the guard's shoulder.

The others tensed, but he was already inside their minds.

A pulse of raw psionic pressure erupted outward.

One collapsed instantly, clutching his skull as his nervous system shut down.

Another fell into violent convulsions, his body betraying him.

The last stood frozen, his consciousness shredded into fragmented thoughts.

"Loyalty is commendable. But blind obedience is fatal."

Eidolon stepped over their bodies, his bag of stolen relics floating behind him, and disappeared into the shadows.

By the time reinforcements arrived, all that remained were echoes of screams and shattered minds.
