The air on the upper ridges of Mount Vesuvius was thick with the suffocating stench of sulfur and scorched pine. The ground beneath groaned, a continuous, low-frequency tremor that rattled the loose volcanic scree down the steep slopes. Gray ash had already begun to drift from the heavy, roiling cloud capping the peak, dusting the wild olive trees like a premature frost.
Selene stepped out into a clearing of black basalt rock, her breath coming in sharp, deliberate measures. Her mortal disguise was entirely discarded. Her porcelain skin caught the unnatural orange glow of the mountain's throat, and her eyes were completely flooded with an inky, telepathic darkness.
She stopped. The phantom frequency that had haunted her for eight hundred years had stopped moving. It was right ahead of her.
Standing in the center of the desolate ridge, framed against the smoke-choked sky, was a silhouette that shattered every theological framework she had ever observed.
It was a monolithic figure, standing well over seven feet tall, clad in a seamless armor of matte, midnight-violet alloy. The suit possessed no joints, no bolts, and no decorative human heraldry; it looked like a singular, fluid entity forged from a dead star. The light of the volcano didn't reflect off its surface; the dark metal actively swallowed the ambient glow, creating a terrifying void in the shape of a warrior.
"You," Selene hissed, her voice carrying a localized telepathic weight that shattered the brittle volcanic stone near her feet. "The silent mover of the bedrock. I have tracked your cold pulse from the temples of Mycenae to the roots of this burning hill. Reveal your name, creature, or I will tear it from your soul."
The armored figure didn't flinch. It didn't take a defensive stance. Slowly, with a mechanical, terrifyingly deliberate rhythm, the monolithic titan turned to face her. Two piercing, brilliant azure optics flared to life beneath the visor.
"Subject: Selene Gallio," a voice rumbled from the chest plate. It was a sound devoid of human resonance, flat and clinical, yet it carried the absolute weight of a computer executing a diagnostic. "Current chronological age: approximately eighteen hundred years since baseline biological awakening. Mutant proto-external classification."
Selene's eyes narrowed, her arrogant confidence instantly fracturing against the cold precision of his words. "You know my name?"
"I have monitored your development for fourteen hundred and twenty-one years," David stated, his azure eyes scanning her frame as a thin sheet of text and mathematical algorithms streamed across his internal HUD.
Out loud, he began reading the telemetry, treating the ancient, feared sorceress like a specimen on a laboratory slide.
"Comparing current metrics to the baseline recorded during the diagnostic spike of 800 BC in the Aegean Basin," David continued, his level voice carrying over the roaring of the volcano. "Your raw telepathic pressure has increased by forty-two percent. Cellular density: stabilized. The unique biological capacity to siphon and metabolize human lifeforces has optimized, resulting in an estimated cellular equilibrium that renders you functionally immortal. However, your reliance on atmospheric mystical currents introduces a structural inefficiency of roughly seven percent."
...She is trembling, David... the symbiote's heavy, dual-layered whisper vibrated inside his mind, its fluid presence coiling tightly beneath his armor plates. ...The witch does not like the math. She wants to bleed us. Let me stretch our fingers... let us taste her magic...
"Maintain containment," David commanded the symbiote internally. "The assessment is not yet complete."
Selene's face contorted into a mask of pure, feral rage. For two millennia, men had knelt before her. Pharaohs had offered her sacrifices, and Roman senators had begged for her favor. To be spoken to like an unrefined resource, to have her godhood reduced to percentages and structural inefficiencies by a giant of violet iron, was an insult her immortal ego could not survive.
"You dare measure me?" Selene screamed, her hands whipping forward.
She didn't use an unrefined telepathic push. She unleashed a massive, concentrated torrent of dark, chthonic sorcery, a swirling vortex of shadowy, necrotic flames that tore up the solid basalt rock of the ridge as it surged directly toward David's chest. The magical blast was dense enough to incinerate a legion of Roman soldiers in a fraction of a second.
David didn't dodge. He didn't even raise his arms. He simply planted his heavy, matte-black boots into the volcanic ash and let the magical inferno strike him dead-on.
The necrotic flames slammed into the Vibranium-T-O-Symbiote matrix with a deafening, thunderous CRACK.
But there was no explosion. There was no smoke.
The moment the magical energy made contact with his armor, the Vibranium lattice within his skin instantly matched the kinetic frequency of the blast, drinking the force of the impact. Simultaneously, the uncorrupted Symbiote layer acting as his physical vanguard absorbed the raw, thermal heat, converting the chaotic energy into localized power storage for the ship's relays below. Within three seconds, the massive vortex of dark fire was completely swallowed, leaving David standing entirely uninjured, his violet alloy humming with a faint, temporary purple glow.
David checked his internal HUD. "Energy absorption metrics: optimal. The kinetic-dampening capabilities of the Vibranium matrix remain absolute against primordial mystical outputs. Thermal conversion efficiency: ninety-four percent."
He looked back up at Selene. The ancient sorceress had stumbled backward, her face completely pale, her dark eyes wide with a profound, existential terror she hadn't felt since her childhood. Her ultimate spell had been completely metabolized like a standard caloric intake.
"What... what are you?" she gasped, her voice cracking as she stared at the seamless, unblemished violet chest plate. "No god... no mutant... can simply eat the dark arts."
"You confuse advanced thermodynamic manipulation with divinity," David said calmly, stepping forward. His massive footprint left a perfectly compacted, silent impression in the shifting ash. "I am not a god, Selene. I am the infrastructure that will survive the entities currently hunting your world from the stars. Your magic is a fascinating variable, but it operates on a localized, primitive scale."
He stopped precisely five paces from her, his towering frame casting a long, shadow-clad silhouette over her trembling form.
"The mountain behind us will erupt in exactly thirty-six hours," David informed her, his azure eyes locking onto hers with a cold, absolute clarity. "The city below will be buried. My sub-relays will harvest the kinetic output of the cataclysm. You will not interfere with that harvest."
Selene stared up at him, her mind frantically trying to process the sheer, unfathomable scale of the entity standing before her. He wasn't a king to be seduced, nor a monster to be slain. He was a cold, calculating force of nature that had been watching her from the dark for over a thousand years.
"And if I refuse?" she whispered, her pride desperately fighting against the cold logic of her survival instinct.
"If you interfere, I will be forced to neutralize you as a systemic risk," David replied, his right arm fluidly shifting as the symbiote and T-O nanites sprouted a heavy, jagged executioner's glaive that hummed with a tearing, micro-vibrational frequency. "Your immortality is a biological equilibrium. It is not mathematically absolute. I can dismantle your cells atom by atom and store your genetic material in a stasis tube for the next three thousand years. It would be an inefficient use of my processing time, but it is an acceptable contingency."
The glaive held its position for one long, terrifying second, the microscopic vibration of the edge dissolving the falling volcanic ash before it could even touch the metal.
Then, with a smooth, liquid motion, the weapon flowed back into David's arm, smoothing over until his skin looked like polished cosmic armor once more.
"Consider your options, Subject Selene," David stated, turning his back to her as he walked toward the hidden entrance of the volcanic transit hatch. "We will intersect again when your understanding of the universe has matured to match my metrics. Do not touch the pillars."
With a silent, hydraulic hum, the cloaked rock face parted, and David stepped into the dark, leaving the oldest mutant on Earth standing alone on the roaring, ash-choked slopes of Vesuvius, her entire reality permanently shattered.
