Arthur's Secret Base
The portal didn't close so much as it collapsed, flickering out of existence the moment Arthur cleared the threshold.
He didn't stick the landing.
His legs simply gave out. He pitched forward, hitting the cold polished floor of his laboratory with a dull thud. The Space Stone tumbled from his fingers, rolling across the floor until it clinked against a cabinet leg.
Alarms blared instantly.
"MASTER!"
Winky appeared with the sharp crack of displaced air. She took one look at the crumpled form on the floor and didn't hesitate. She snapped her fingers, levitating him immediately as she rushed toward the medical bay.
"Eve! Full diagnostic!"
"Already running," the AI responded, her voice carrying an edge of concern that shouldn't have been possible for artificial intelligence. "Initiating comprehensive biometric scan."
Winky's hands glowed with soft healing magic as she worked, stabilizing what she could. Monitors flickered to life around the bed, holographic displays painting the air with data streams.
Arthur's vital signs were erratic. Heart rate elevated. Blood pressure fluctuating. Neural activity spiking and dropping in irregular patterns.
But it was his face that made Winky freeze.
Arthur, who had maintained the youthful appearance of a twenty-year-old for years, looked different. His skin was pale and papery. And his hair, usually a thick raven black, was now shocked with heavy, jagged streaks of grey at the temples.
He looked like he had aged twenty years in twenty minutes.
"Eve," Winky whispered, her large eyes wide with horror. "Master's hair..."
"I see it." The AI's voice was quiet. "Continuing analysis."
—
Ten Hours Later
Arthur woke with a groan.
It felt less like waking up and more like clawing his way out of a grave. His head pounded with a rhythm that felt like a hammer on an anvil. His mouth tasted like copper and ash.
"Lights," he croaked. "Dim... fifty percent."
The harsh laboratory lights softened instantly.
He tried to sit up, but a wave of nausea and vertigo slammed him back against the pillows. The room spun lazily.
"I would advise against movement, Sir," Eve's voice floated through the room, gentle and insistent. "Your equilibrium is currently compromised."
Arthur rubbed his eyes, noting vaguely that his hands were trembling.
"Eve. Damage report."
"You've been unconscious for ten hours and twenty-three minutes."
"That long?" Arthur let out a slow, shaky breath. "I'm in for some bad news, aren't I?"
He turned his head slowly, catching his reflection in the polished metal surface of a nearby instrument tray. He froze. He reached up, touching the silver-grey streaks at his temples.
"Well," Arthur rasped. "That's a new look. Tony is going to call me 'Grandpa' if he sees this."
"The aesthetic changes are the least of your concerns." A holographic display materialized above his bed, showing a rotating 3D model of his body. It was lit up with angry red warning signs.
"Give it to me straight."
"Starting with the expected issues," Eve began. "Your magical pathways have sustained significant damage from the prolonged use of the Arcane Mage State."
"How bad?"
"Worse than projected. The state was designed for intense but brief engagements. You maintained it for over thirty minutes while engaging in continuous high-level combat and channeling energy from both the Power Stone crystal and the Space Stone."
Arthur nodded slowly. That part he'd expected.
"All of that was tested in simulations," he said, fighting a headache. "Why the extreme damage?"
"We never tested in actual high magic combat within a hostile dimension that actively fought back against your existence. You should not have held the state for more than fifteen minutes."
Arthur frowned. "Why am I hearing about this now? No warnings popped up during the battle. The HUD countdown didn't change."
"Master, Hell's dimensional radiation severed my connection to the suit the instant you crossed over. I was blind. You may not have noticed the lack of my assistance due to the intensity of the battle, but the HUD was operating in safe mode. It wasn't receiving feedback."
Arthur let out a long sigh, closing his eyes. "I really didn't have a second to think about anything else in that fight. My fault. I shouldn't have blindly trusted the display." He paused, the implication sinking in. "So... how was I holding the Arcane State for the extra time if the suit wasn't regulating it?"
"Sir, the answer is in your hair."
"Vitality?"
"You kept the state active by unconsciously drawing on your life force. You burned years off your life in minutes. The grey in your hair is a visible symptom of rapid cellular decay."
The room went quiet.
"How bad?" Arthur asked softly.
"If untreated? Permanent reduction in physical capabilities by forty percent. Permanent reduction in magical capacity by thirty percent. Accelerated aging going forward." Eve paused. "Your lifespan has likely been shortened by decades. The damage was compounded significantly when you channeled the actual Space Stone while already in a compromised state."
Arthur absorbed that in silence. Decades gone. Just like that.
"What's the solution?"
"I've been cross-referencing your condition with the experimental compounds in your cold storage. Several of your vitality potions show promise."
Arthur almost smiled. "The ones I made for Eileen."
"Precisely."
Arthur had been aging slowly for years, far slower than any normal human should. Whether it was Death's Mark, his chi cultivation, the magical enhancements he'd accumulated, or some combination of all three, he simply didn't age at a normal rate.
He still looked like he was in his twenties while Tony Stark had grey temples and crow's feet.
But Eileen was human. Fully, completely human.
Arthur had realized early in their relationship that if he lived for centuries, which seemed increasingly likely, he would watch her grow old and die while he remained young.
That was unacceptable.
So he'd researched. Obsessively.
Magical potions from wizarding traditions across the globe. Rare herbs and fruits from K'un-Lun's hidden gardens. Alchemical formulae from Kamar-Taj's restricted archives. Cellular regeneration compounds reverse-engineered from Kree technology.
He'd experimented, refined, tested. Created dozens of prototype potions designed to extend life and preserve vitality.
Eileen had been taking a stabilized version for years now. She didn't look a day over twenty-five.
But Arthur had never needed the potions himself.
Until today.
"Potion Seven shows the highest compatibility with your current condition," Eve reported. "Base ingredients: K'un-Lun immortal peaches and crystallized phoenix tears, stabilized with Kree nano-meds."
"The difficult one," Arthur muttered.
"The effective one." Eve pulled up the compound's specifications. "It should fully restore your vitality and reverse the cellular damage."
"Should?"
"Will. With ninety-seven point three percent certainty."
"And the catch?"
"It works only once. The compound creates a form of biological immunity after initial exposure. Your body will develop antibodies to its specific magical signature. If you damage your vitality like this again, Potion Seven will be useless."
"Once is enough," Arthur said quietly. "I don't plan on making the same mistake twice."
He turned his head toward the door. Winky was standing there, twisting her hands, her eyes glistening with barely contained tears.
"Winky."
She was at his bedside in a blur of motion.
"Master Arthur is awake." Her voice wavered. "Winky is so relieved. Winky was so worried when Master collapsed. Master's hair turned grey and Master wouldn't wake up—"
"I'm fine," Arthur said gently, reaching out to pat her hand. "Or I will be, soon enough. More importantly, I'm glad to see you're all healed up. I took revenge for you."
Winky sniffed, wiping her nose. "Winky is fine. But Master's condition..."
"Has a solution," Arthur finished firmly. "Eve has it ready. No need to worry." He shifted carefully, propping himself up. "How is everyone?"
Winky's posture relaxed a fraction. "The family waited for news of Master before sleeping. They only rested when Winky returned home with word that Master was back and stable. The children were very insistent on staying up, but Mistress Eileen convinced them."
Arthur smiled softly at the image. "Thank you, Winky. What about Ariadne? Tony? And Hulk?"
"Ari is still at the house. She insisted on staying until Master returned safely. Mr. Stark had to leave. The one-eyed bald man called him away for urgent business."
"Fury." Arthur rolled his eyes. "Looks like he's going to make some big moves with Tony."
"The green man has been transferred to one of Master's remote properties for the night," Winky continued. "Young Master Tristan made Winky promise to bring him back the moment Master woke up. But Winky decided to wait for Master first."
"Good call." Arthur swung his legs over the side of the bed, fighting down the lingering dizziness. "I'll handle things later. But first, let's get this healing done. Eve, walk us through it."
Winky retrieved the potion from cold storage.
It was a small, reinforced vial containing a luminescent green liquid that swirled with its own inner light. The Immortal Peach extract gave it a soft, heartbeat-like pulse.
"This will hurt," Winky warned, preparing a specialized syringe designed for magical compounds. "The restoration process is... aggressive."
"I just fought Mephisto in Hell," Arthur smirked. "I think I can handle a needle."
Winky gave him a look that suggested he was an idiot, but she loaded the syringe with precise, practiced movements. The green liquid filled the chamber, casting strange shadows across the medical bay.
"Ready?" she asked.
"Do it."
The needle slid into his arm. Winky depressed the plunger.
The green liquid began flowing into Arthur's bloodstream.
For a second, nothing happened. Then, fire.
It wasn't painful, exactly, but it was intense. A rushing, roaring warmth that flooded his veins like sunlight breaking through a dam. The monitors around the bed erupted with activity. Heart rate stabilized. Blood pressure leveled out. The angry red warnings on the hologram flickered to yellow, then to a soothing green, one by one.
Arthur gasped as the fog in his head evaporated. The trembling in his hands ceased instantly.
He looked at the reflection in the instrument tray. He watched as the grey streaks in his hair darkened, the black reclaiming the roots and spreading outward, erasing the evidence of his brush with mortality until his hair looked exactly as it had that morning.
Five minutes later, the sensation faded to a hum.
"Cellular reconstruction complete," Eve announced. "Vitality levels restored to baseline. Physical capabilities returning to normal parameters. The grey hair phenomenon has been fully reversed."
Arthur flexed his fingers experimentally. Strong. Steady.
"It worked," Winky breathed, her shoulders slumping in relief.
"It worked," Arthur agreed, standing up. The dizziness was gone. He felt light. "I feel... better. Much better."
"You are not fully recovered," Eve cautioned, ever the buzzkill. "Your magical pathways are still damaged. Estimated repair time is twenty-four to thirty-six hours before you can safely channel wizarding magic again. And I strongly recommend you avoid direct Infinity Stone contact for the foreseeable future."
Arthur stretched, his back cracking. "Noted. No more fighting Hell Lords in their own dimensions. At least not this week."
Winky didn't laugh. She looked up at him with solemn eyes.
"Master Arthur," she said quietly. "What happened in there?"
"I won," he said simply, offering her a reassuring smile. "Mephisto is locked in Hell. He can't reach Earth anymore. He can't reach us."
"Forever?"
"That's the idea." Arthur offered his hand. "Winky, let's head home. I have a family to reassure and a very excited young wizard who apparently wants his pet Hulk back."
Winky's face split into a wide, teary smile. "Yes, Master Arthur!"
She grabbed his hand.
"Let's go home."
