The next day arrived without mercy, and Apeiron dragged himself into the dojo long after the others had already taken their places. His body was a ruin of bruises and swelling, muscles locked tight with pain, joints stiff and unresponsive with every step he forced himself to take. Others bore marks of training as well, split lips, bandaged arms, the dull ache of effort written across their posture, but nothing close to his condition, nothing that spoke of being crushed again and again without reprieve.
And the day unfolded exactly as it always did.
Class followed class without pause, each one stripping away another illusion. Grappling sessions left him pinned beneath opponents who never overextended. Striking drills exposed openings he could not yet close. Speed trials mocked him with opponents who moved before he could finish deciding to move. Strength contests reminded him, brutally, that will alone could not bridge every gap. Pressure point training shut his body down in ways he was still learning to undo, while tactical exercises revealed just how far behind his awareness truly was.
Every discipline delivered the same verdict.
He lost.
He lost to fighters who could see the future before it happened and adjusted without effort. He lost to warriors who stepped cleanly between moments of time, reappearing where he least expected them to be. He lost to gods whose bodies were shaped by transcendence itself, beings for whom gravity, momentum, and endurance were optional inconveniences rather than rules. Against them, Apeiron was slow, fragile, and incomplete, a human pushing against a wall that refused to acknowledge him.
Weeks passed like this, bleeding into one another without relief.
On the weekends, he returned to Olympus, and there he found something the dojo could never take from him.
Pandora.
He visited her whenever his body allowed it. Some days they walked slowly through the palace's quiet halls, his steps measured, her pace matched his. Other days, when movement hurt too much to risk, they sat together in the garden.
It had started as a place of recovery. It became something else.
They tended it side by side, hands in the soil, planting new shoots where older ones had withered, guiding vines along broken stone, coaxing life back into places that had once been forgotten. Apeiron moved carefully, favoring bruised limbs and strained joints. Pandora worked patiently beside him, never rushing, never asking him to be stronger than he was.
When the pain grew too sharp, she used her power. Subtle and gentle, never overwhelming. cosmic warmth passed through her hands into his body, easing fractures that had not yet healed, knitting muscle and nerve just enough for him to breathe easier. She did not erase the cost of his training. She made it survivable.
They talked while they worked. About his training. About her recovery. About the futures they wanted but were afraid to name out loud. They spoke of dreams, of who they wished to become, of a life that might exist beyond duty and expectation.
When Apeiron spoke of his failures, she listened without interrupting. And when he finished, she never answered with pity.
She answered with belief.
She never told him to quit.
She reminded him why he had begun.
And because of her, every Monday, no matter how broken his body felt, Apeiron returned to the dojo.
Three months into training, he did not walk into the dojo.
He crawled.
His hands scraped against the cold stone as he pulled himself forward, breath shaking in his chest, vision blurring at the edges. Every attempt to stand ended the same way, his legs giving out beneath him as pain dragged him back to the ground.
Theseus approached, arms folded, watching in silence for a long moment before speaking.
"…I'm impressed," he said at last. "Three months, and you still haven't quit."
Apeiron forced himself upright, swayed, and collapsed again, his breath coming in ragged pulls as sheer will refused to let him remain on the ground. He lifted his head despite the pain burning through every muscle, his voice hoarse but unbroken as he spoke.
"I won't quit," he said. "Something is changing. I'm stronger not quickly, not enough yet but it's real."
For the first time, his words did not carry the fragile edge of hope.
They carried certainty.
His hands clenched into fists against the stone, knuckles whitening as something colder and deeper settled into his resolve.
"I will avenge my family," he said quietly. "My father. My mother. My brother."
Theseus studied him in silence, the weight of that resolve pressing even on him.
I have never seen will like this, he thought, not even among gods.
Aloud, he turned back toward the class, his expression unreadable as the moment passed.
"I'll be back," he said simply.
He lifted Apeiron with one arm and opened a fold in space.
They fell.
The world shifted into a separate pocket dimension vast, enclosed, and deliberate. This place had not been built for comfort. It had been built for training.
The space was filled with equipment. Suspended targets hovered at different heights, slowly drifting. Shifting constructs reconfigured themselves in response to motion and intent. Along the perimeter stood living magical dummies humanoid frames bound with runes, their surfaces flexing as if alive. They watched. They adjusted. They were made to fight back.
But all of it felt secondary to what lay at the center.
A massive lake stretched outward, its surface unnaturally still.
This was the Lake of Suffering.
It healed all wounds.
Flesh knit back together. Bones reformed. Nerves reconnected. No injury was beyond it.
But the lake did not heal kindly.
To enter it was to be forced inward, dragged through the deepest corridors of one's own mind. It did not create pain it remembered it. Every fear buried. Every loss denied. Every moment the soul had fractured and pretended it hadn't.
The suffering did not come in waves.
It was infinite.
There was no relief. No fading. No mercy in repetition. The lake trapped you in your worst nightmare and made it endless your worst pain, your most unbearable truth, replayed without distortion, without escape. Time meant nothing inside it. Endurance did not shorten it. The mind was forced to confront everything at once, forever, until it either accepted it… or broke.
Most gods could not endure it for more than a few seconds. They would rise screaming, minds splintered, bodies healed but wills shattered. For them, the healing was never worth the cost.
The Lake of Suffering did not break the body.
It tested whether the mind deserved to keep it.
Apeiron struggled in Theseus's grasp.
"Don't take me out of training," he said urgently. "Don't treat me differently. I want to be a warrior."
Theseus set him down gently.
"This is training," he said. "It's called healing."
He lowered Apeiron nearby the lake.
"This is restorative water," Theseus explained. "It heals flesh, bone, and nerve but it exacts a price. As it repairs the body, it drags the mind backward, forcing it to relive its worst trauma. Not once. Not selectively. All of it."
He let the words settle.
"Most cannot endure that. Their bodies recover, but their wills do not. The psychological damage breaks them long before the healing is complete."
His gaze shifted to the surrounding space.
"This pocket dimension makes it worse," Theseus continued. "Time does not exist here. There is no forward or backward, no relief through passing moments. Extended exposure erodes identity itself. The mind begins to lose its sense of before and after."
He reached into his cloak and held out another crystal, its surface faintly pulsing.
"This will grant you access to this place," he said. "You may train, heal, then train again for as long as you choose. Within this realm, time does not impose age or exhaustion. You can remain here for what feels like years even eons and when you return, less than a second will have passed outside."
He tapped the crystal lightly.
"It also allows you to move where time does not exist. In zero-time zones, where motion should be impossible, it will anchor you letting you act, breathe, and endure when time itself has been stripped away."
He met Apeiron's eyes.
"That is why you must keep the crystals on you at all times. It anchors you to reality beyond this place. Without it, the void here would consume you. You would not survive."
Theseus's voice hardened as he reached his decision.
"I doubt this will make much difference in the end," he admitted honestly, "but I would rather you struggle on your own terms than continue to be broken by those who were born with power you do not possess."
He raised a hand, and light folded inward as a portal began to form, its edges warping space with quiet finality.
"You will train here alone," he continued. "Not against killers shaped by divine blood or supernatural gifts, but against yourself, your limits, and whatever you can carve out through will alone."
His gaze sharpened as the portal stabilized.
"Do not stay long," he warned. "Most who linger in places like this lose themselves. Stripped of resistance, stripped of reference, they become something else."
He hesitated, then finished softly.
"They become… empty."
Before Apeiron could respond, Theseus stepped back and vanished into the closing light, leaving the portal behind and the warning hanging in the air.
Apeiron lowered himself into the lake, and the pain did not strike his body.
It struck his mind.
The water closed around him, and memory surged forward all at once, violent and unrestrained. Fire tore through the night sky as his father moved instinctively in front of them, shielding them with his body. His mother's hand slipped from his grasp as the ship ruptured, her scream ripped away by vacuum and thunder. His brother vanished in an instant, one moment beside him, the next replaced by emptiness where a life should have been. Above it all, gods clashed, their war tearing his world apart as though it had never mattered.
Loss pressed in from every direction, intimate and suffocating, the lake itself knew exactly where to reach.
And it did not let go.
He saw it again and again, the same moments replayed without mercy. Fire. Falling bodies. The silence after screaming ends. Each memory struck with perfect clarity, not dulled by time, not softened by distance.
Apeiron screamed and dragged himself from the lake, collapsing onto the stone as air rushed back into his lungs. The pain vanished instantly, but his injuries returned just as fast, broken bones screaming their presence as reality reasserted itself.
He stared at the water for a long moment.
Then he stepped back in.
The memories struck again, and again he endured them, but each cycle went further than the last, digging deeper, refusing to stop at the surface of grief. When he emerged, he did not rest.
He destroyed himself with a singular, terrifying focus.
He shattered his hands against unyielding stone and living constructs alike, striking until every bone gave way and his fingers collapsed into useless shapes. The training dummies did not yield; they struck back with calculated brutality. Each impact punished his mistakes, and every counter-blow drove force into his arms until even the clarity of pain was lost to a dull, throbbing roar. He continued anyway, cycling through every martial form in his arsenal refining his footwork, perfecting his timing, and sharpening his angles striking until his very body failed beneath the weight of the repetition.
He drove his limbs far beyond their natural limits, breaking them under the sheer force of his refusal to stop. His bones splintered as he struck constructs designed to adapt and resist, and when they countered, they broke him in return. He ran until his legs failed him completely, sprinting through the endless space, leaping and pivoting in a frantic dance of violence until his bones fractured beneath his own weight and his feet were crushed by the distance he demanded of them. When even that was not enough, he slammed his skull against the stone until the darkness finally claimed him.
Then, broken, bleeding, and barely conscious, he crawled back to the lake.
The water accepted him, but its grace was cold. It rebuilt what he had destroyed slowly and cruelly forcing him to relive every loss, every scream, and every moment his world had ended while his body was stitched back together piece by piece. His flesh restored itself even as his mind was flayed open, suffering layered upon suffering without mercy or reprieve.
When the healing finally finished, he rose from the depths, and he did it all again. His hands, his arms, his legs, and his skull each was offered up to the strike, the counter, and the inevitable break. He would heal only to break again.
There was no counting the cycles and no way to measure the passage of time. In a realm where time did not exist, he endured an eternity that could not be named, a place where days, years, and lifetimes held no meaning, and repetition was the only constant left to him. Every cycle sharpened his technique; every failure corrected itself in blood and fracture. Every form he knew was refined against a resistance that did not tire, until the man and the art became one.
When he finally judged it was enough, he returned to the lake one last time, letting the water rebuild what his training had broken even as it punished his mind with the familiar visions of fire, falling bodies, and the emptiness where his brother had been.
When the healing finished, he rose without hesitation, took the crystal in his hand, and stepped back into the dojo returning to the exact instant he had left, as though no more than a heartbeat had passed outside the pocket dimension.
He stood at the edge.
And watched.
From the edge of the hall, Apeiron studied the warriors as they trained how they shifted weight, how they struck, where their balance broke and recovered. He traced movements in the air, mimicking forms without power, without speed, memorizing angles and timing instead of force.
He could not compete with them, so he learned from them instead, watching their movements, their timing, their habits, and filing every mistake and every success away for later.
At night, he returned home and spoke with Pandora, their conversations drifting from long silences to soft laughter to a quiet understanding that needed no explanation, until sleep claimed him mid-sentence more than once.
Weeks passed in this way.
Then months.
One night, as they spoke like they always did, Pandora went quiet.
When she spoke again, her voice trembled.
"Apeiron," she said softly, and he could hear that she was crying. "You… you can't visit me anymore. At least not for a while."
He sat up at once, the fatigue leaving him. "Why?" he asked. "Did I do something wrong?"
"No," she said quickly, wiping at her tears. "No, it's not you. It just… happened again. A group of bandits, Pirates and Soldiers. They tried to take me. Olympus stopped it, but now everything's on high alert. No visitors. No exceptions."
His jaw tightened, anger flaring before he forced it down. "Can we still talk?" he asked. "Using the crystals device?"
"I would want nothing more," she said without hesitation.
He exhaled, some of the tension easing, though the ache remained. "I don't think I could go a day and not talk to you," he admitted. "Honestly, I think I'd have a hard time even showing up to training if I couldn't."
She managed a weak laugh through the tears. "Then don't stop," she said gently. "Keep training. Tell me about it like you always do."
So they kept talking, about training, about small victories, about nothing important at all, filling the space between them the only way they could. When the call finally ended, Apeiron lay staring at the ceiling for a long time, knowing that even separated, even watched, even threatened, they would continue exactly as they always had.
Together.
The very next day, he woke and returned to training.
Somewhere within that endless repetition, something began to change. His body grew stronger, denser, more resilient. Speed increased beyond what a human should have sustained. Muscles adapted. Bones hardened. Endurance became unnatural. He was different than before, not enough to match them, but no longer the same.
Apeiron stood at the edge of the dojo, watching others train, beings who bent time, folded space, and wielded power as naturally as breath. After a moment, he closed his fingers around the crystal and stepped away from them once more.
Inside the pocket dimension, he trained without interruption.
He ran across the infinite plane until his lungs burned and his legs screamed, forcing himself to continue long after instinct demanded he stop. When he finally slowed, it was not by choice. He stood there shaking, breath ragged, and the weight of it all crashed down on him.
Tears streamed down his face.
"What's the point?" he whispered. "I'll never catch them."
"I'm too weak," he said aloud. "I can't protect anyone like this. I can't avenge them."
For a moment, the thought of an easier path tempted him.
His thoughts turned to Pandora, to her voice, her smile, the way she believed in him when no one else did. Then to his family, to fire in the sky, to hands slipping from his grasp, to the promise he had made over their deaths.
Then he dismissed it.
There was no easy way.
He turned and struck the nearest construct with everything he had. Bone snapped, pain dropped him instantly, and he crawled to the lake, lowering himself into its depths as memory and healing tore through him together.
This became the rhythm.
Train, Break, Heal and Endure.
In a realm without time, he remained until suffering dulled and endurance became reflex. He left only when he decided it was enough, stepping back into the dojo at the exact instant he had departed, then returning home to sleep, to wake, and to begin again.
Months passed in the outside world.
Then one day, everything changed.
Apeiron lay beneath the surface of the Lake of Suffering as the last echoes of fire, falling bodies, and empty silence washed through him, and when the water finally released him, he rose fully restored and walked toward the training grounds without urgency or thought.
He stopped in front of the punching bag.
He struck once.
It was not the same.
A presence gathered around him, dark, silent, and absolute, not energy and not force, but something deeper, as his very presence pressed outward. The space in front of his fist emptied before the strike arrived. Time thinned. Distance lost meaning.
The punching bag tore free from its anchor and vanished across the dimension, reduced to fragments by something Apeiron did not yet understand.
He stared at his hand.
Something had changed.
"I think…" he whispered, "…I figured it out."
He did not celebrate.
Instead, he moved.
Apeiron broke into a run, and the ground fell away beneath him as his stride lengthened beyond anything he had known before. With each step, distance compressed unnaturally, his body clearing impossible spans in a blink as the space ahead of him thinned and gave way. He leapt, higher than he ever had, higher than his instincts believed possible, and the air distorted around him as he descended.
He struck again.
His punches came faster than thought, each motion warping the space it passed through, the dimension bending and trembling as reality itself is struggling to keep up.
Then he stopped.
Without another word, Apeiron took the crystal and stepped back into the dojo, returning to the exact instant he had left. To the world around him, nothing appeared to have changed; he was still bruised, still human, and still the weakest presence in the room. He remained a silent ghost among the living. He did not tell his uncle, he did not tell the instructors, and he did not tell a soul what he had seen or where he had gone.
That night, he returned home and ate in silence, speaking with Pandora as he always did. He laughed when laughter was expected and listened intently when she spoke, but he kept the transformation burgeoning inside him a secret. He slept a dreamless sleep, and the next day, he returned to the dojo.
He lined up with the others, his eyes fixed forward and his posture unremarkable. Before the training truly began before anyone could even notice he was gone his hand slipped into his pocket, and he stepped away, back into the pocket dimension.
The moment he arrived, he felt the difference.
He moved his arm, and the motion was effortless, devoid of the friction that once governed his movements. He clenched his fist and struck a nearby construct harder than he ever had before. Nothing broke. He kicked with the force of a falling world, yet nothing shattered. Finally, he slammed his head against the wall, expecting his bone to crack and the familiar bloom of pain to follow.
There was nothing. His body absorbed the impact without resistance or damage, as though it no longer recognized the very concept of breaking.
Apeiron stared at his hands for a long moment, the silence of the dimension ringing in his ears. He realized then that he needed a new approach. "This time," he said quietly to the void, "speed."
He ran.
At first, it was the same as always. The infinite plane stretched outward, silent and empty, as his breathing settled into a rhythmic hum. His stride was controlled and familiar, the gait of the boy he used to be. Then, he pushed not with reckless abandon, but with absolute precision.
His feet no longer fought the ground. Resistance thinned and then vanished entirely, as if the space ahead of him were being removed rather than crossed. A faint black presence gathered around his body; it was not energy or power, but a pure, undeniable presence. Space itself failed to remain intact in front of him, folding inward and giving way to his will. He ran faster than sound, faster than reaction, and eventually, faster than light could properly form intention. Time did not pursue him; it bent to accommodate his passage.
Then, he felt something new. He slowed and lifted his head, sensing a change in the dimension far beyond where he had ever dared to go.
Gravity.
He stepped forward deliberately, and the weight pressed down instantly ten times that of a normal world. His bones groaned and his muscles tightened as the ground began to resist his every move. Yet, he remained upright.
He ran again. The farther he went, the more the gravity climbed. Twenty times. Thirty. Each step demanded absolute alignment; any inefficiency would have crushed him, and any wasted motion would have torn his body apart. The black presence around him did not flare or expand, but instead compressed tighter against his form as he continued his journey into the heavy dark.
There was no ceiling, no boundary, and no limit. Gravity climbed endlessly the deeper he moved into the dimension, pressing down with a force that would have pulverized even the strongest warriors. In that crushing depths, he trained. He struck until he collapsed, and then he returned to the lake.
The Lake of Suffering rebuilt him slowly and without mercy, forcing his mind through the familiar cycles of loss and terror while his body was restored piece by piece. Every time he could stand again, he returned to the gravity field and pushed farther than he had the time before.
Again. And again.
Inside the pocket dimension, time did not exist. He remained until destruction, healing, and endurance blurred into a single continuous state. When he chose to leave, he used the crystal and returned to the dojo at the exact instant he had left, no time had passed at all.
He repeated this cycle day after day for months in the real world.
The gravity never stopped increasing, but eventually it could no longer find a way to break him, not because the weight vanished and not because his body had become invincible, but because force had nowhere to accumulate. Stress did not gather. Pressure did not echo. It passed through him and dispersed into nothing.
He was no longer resisting gravity.
He was denying it inefficiency.
Eventually, he realized something unsettling.
He could no longer hurt himself.
No matter how hard he struck or how violently he moved, there was no failure point left to exploit. The Lake of Suffering became unnecessary, not because pain was gone, but because pain required a system, and he had removed it.
His body had not grown stronger in the way others measured strength.
It had become emptier.
He told no one. Not his uncle. Not the instructors. Not Pandora. Every return to the dojo placed him back at the same moment he had left, unchanged to the eye, though something vast had already concluded within him.
Then the day finally came.
Apeiron walked into the dojo beside Theseus and held out both crystals in his open palm.
Theseus frowned, turning them over in his hand.
"Why are you returning these?" he asked, neither angry nor curious, only measuring. "Are you telling me you're giving up on your training?"
Apeiron stood a little straighter than before. Leaner. Denser. Still unremarkable to the eye, still unmistakably human.
"I don't need them anymore," he said. "I'm ready to train with the others."
Theseus studied him in silence, the way a master studies a stance before correcting it.
"You've been here two years," Theseus said at last. "Two years among warriors who bend time, tear space, and wield forces you cannot sense, much less command."
His gaze hardened.
"You stand beside beings who shape fire, water, earth, and lightning as extensions of their will. Warriors whose bodies are reinforced by magic, bloodlines, or divinity. Some move at speeds that fracture perception. Others strike with strength that collapses terrain."
He gestured toward the open space where the pocket dimension waited.
"That realm has no air. No stable gravity. Distance alone kills the unprepared. The vacuum strips breath from mortals. The gravity there will crush a human frame long before combat even begins. Without that crystal, you would die before the warm-up ended."
His eyes returned to Apeiron.
"And yet you stand in front of me with this confidence."
Apeiron met his eyes calmly.
"I know," he said. "That's why I've been preparing."
Theseus exhaled slowly, the faintest restraint entering his voice.
"Preparation is not mastery," he said. "And belief does not keep air in your lungs."
Apeiron smiled not in defiance, not in pride.
"Then watch," he said.
Theseus held his gaze for a long moment before giving a single nod.
"Very well," he said. "Line up."
As he turned back toward the class, he added without a backward glance, "Don't die. You're still my nephew. I'll step in if I have to."
The warriors assembled in a disciplined line. Space folded before them, and the pocket dimension opened like a silent, hungry maw. They readied themselves to race, stretching their limbs and igniting their innate powers. Fire licked at the ground beneath the feet of some, while others shimmered with the intense glow of magic, localized gravity, lightning, or impossible speed.
No one looked twice at Apeiron. No one knew what he had been doing in the depths of that crushing silence. They saw only a human bruised, quiet, and profoundly ordinary.
But Apeiron was ready. And for the first time, the world was about to see the cost of the work it never witnessed.
