Chapter Four , The Path of the Empty Fist
Theseus and Apeiron sat across from one another at a long stone table, the fire between them burning low.
Apeiron told him everything.
About the attack.
About the gods who descended like storms.
About his parents falling from the sky.
About his brother being torn away and lost among the stars.
He spoke until his voice finally failed him.
The table split with a thunderous crack as Theseus's fist came down, stone fracturing beneath his knuckles. The hall fell silent.
"I warned my brother," Theseus said, his voice low and iron-hard. "I told him never to grow complacent. Never to leave Olympus unprepared." His jaw tightened. "He chose otherwise."
He turned his gaze to Apeiron. The fury in his eyes dimmed, replaced by something heavier older.
"And now he is gone."
Theseus straightened, towering over the chamber. "Hear this clearly," he said. "You are under my protection. No one will lay a hand on you here. Kosmos Maches is neutral ground the safest ground in existence. Warriors from every realm come here to train, to test truth through combat. Even gods honor its laws."
His eyes hardened again. "The ones responsible for my brother's death will answer for it. In time. We wait for the word from Zeus."
He paused, studying Apeiron. "You remember the one who killed him."
Apeiron nodded. "He was a giant. He called himself Modi."
Theseus exhaled through his teeth. "I should have known," he muttered. "One of Thor's sons. That drunk fool leaves ruin wherever his blood walks."
Apeiron stepped forward and then dropped to his knees.
"Please," he said, his fists clenched, knuckles white. "I've seen the warriors here. Their strength. Their discipline." His voice steadied. "Before my father died, I saw him fight. And before the end, he told me the truth."
He looked up, eyes burning with resolve. "He said you trained him. He said you taught him a martial art."
Theseus said nothing.
"He called it Mu no Ken," Apeiron continued. "The Empty Fist."
Silence stretched between them.
"Teach me," Apeiron said. "Not so I can rage. Not so I can beg the gods for mercy." His voice did not break. "Let me earn it. Let me carry it."
He bowed his head.
"I know who destroyed my family," Apeiron said. "Let me face them. Let me be the one who ends it."
Theseus rose at once.
"No."
The word struck like a shield slammed into the earth.
"You are human," Theseus said, his voice firm, unyielding. "And I will not send a human to die fighting gods." His gaze hardened, but there was no cruelty in it. "You would stand no chance. I know that. And I know, without question, that my brother would never have wanted that for you."
He took a step closer.
"He would not have wanted you thrown into a war you cannot survive."
Apeiron said nothing.
"These arts you speak of," Theseus continued, turning away for a moment, "Mu no Ken is not a single discipline. Across this world, it exists in fragments. Gods take pieces of it and fold it into their divinity. Warriors blend it with steel, magic, blood, speed. Every school here carries an echo of it."
He looked back.
"But the true art," he said, quieter now, "is not a blend. It is the foundation beneath all martial paths. Emptiness. Precision. Denial." His jaw tightened. "Very few have ever understood it. Fewer have survived mastering it. Not because it is forbidden but because it demands something most beings do not possess."
He studied Apeiron carefully.
"I can see it in you," Theseus said. "You are fully human. You take after your mother."
A pause.
"Your father and I were not."
Apeiron stiffened.
"That is why we endured what Mu no Ken demands," Theseus went on. "The art does not test strength alone. It tests what you are made of. It strips away protection, talent, even identity. And most break long before the end."
His eyes sharpened not with anger, but with certainty.
"And we are not Olympus's army. We do not choose when war begins. Zeus has chosen restraint."
He exhaled slowly.
"So we wait."
Apeiron bowed his head, breath uneven.
"Please," he said. "I know I'm human. I know I'm weak. But I can endure." His fists clenched. "I'll train the right way. I'll give everything. When Olympus finally moves, I'll be ready. I'll help stop whoever did this to my family. To my mother. To my brother."
Silence filled the hall.
Theseus looked at him.
Not at the bruises.
Not at the frailty.
At the refusal.
At the grief that did not rot into rage.
At the resolve that did not beg for mercy.
At the will that would not bend.
For the first time, his certainty faltered.
"…Fine," Theseus said at last.
Apeiron looked up.
"You will come with me to class this morning," Theseus continued. "No promises. No shortcuts." His voice hardened again. "If you fail, you are done."
He turned toward the door.
"If you want to be a warrior," he said over his shoulder, "you'll listen to every word I say."
Apeiron sprang to his feet.
He rushed to gather his things, heart pounding, as Theseus stepped out into the early light. Together, they headed toward the dojo.
The moment Apeiron stepped inside, the air changed.
He had been given training attire black and gray, simple and functional. Fitted cloth wrapped his frame, light enough to move freely but dense enough to withstand impact. Gray shoulder guards rested over his upper arms, compact and unadorned, more restraint than armor. Reinforced wraps covered his forearms and boots, built for grip and balance rather than protection.
Warriors filled the vast hall beings of every kind drawn from across the multiverse. Some trained in forms that resembled kickboxing, others in hand-to-hand disciplines so alien they barely looked like combat at all. Power and technique blended seamlessly. Fists ignited with energy. Bodies moved through space without touching the ground. Magic flowed through strikes as naturally as breath.
Apeiron stood still, absorbing every word.
Theseus watched him without blinking.
"You're certain?" he asked. "This isn't ceremony. This isn't a game. People die here."
"Yes," he said. His voice did not shake.
Theseus nodded once.
"Then fall in."
As Apeiron stepped forward, Theseus reached into his cloak and drew out a small crystal clear, unmarked, light folding silently within its core. He pressed it into Apeiron's palm.
"What is it?" Apeiron asked.
"These training grounds were not made for humans," Theseus said. "That crystal will keep you alive." He spoke plainly. "No air. No pressure. You will not suffocate. You will not be crushed."
He met Apeiron's gaze.
"It will not make you stronger. It will not make you faster. It will not save you from failure."
A pause.
"I refuse to watch you die because the environment itself decided you did not belong."
Apeiron closed his hand around the crystal and nodded.
Then he took his place.
He stood alone among gods, monsters, and warriors shaped by power he did not possess the only human in a sea of the inhuman.
Theseus stepped to the front of the hall. The noise vanished the instant he raised his hand.
"We begin with movement," he said. "Run. Fly. Phase. Move however your nature allows."
He let the words settle.
"This is a warm-up. Thirty minutes." His gaze swept the hall. "Go as far as you can."
A faint pause.
"Minimum distance: one hundred thousand light-years."
The class stirred not with disbelief, but anticipation.
Theseus turned his palm outward.
Space folded.
A gateway tore open not into nothingness, but into an infinite dimension shaped by a single act of will. A vast, solid plane extended forward, narrow and deliberate, like a path carved through existence itself. It stretched beyond sight, anchored by form alone.
Beyond the path, there was nothing.
No stars. No horizon. No direction. Only absolute void endless, formless, and unforgiving.
"This is not a race through emptiness," Theseus said. "You will have ground to move upon."
His eyes hardened.
"Leave the path," he said, "and the void will take you."
Without hesitation, the warriors stepped forward.
Some leapt into the void as beams of light. Others dissolved into motion, bending space beneath their feet. Wings unfurled. Magic flared. Bodies vanished forward as if distance itself had agreed to move aside for them.
Apeiron swallowed and followed.
Figures streaked past Apeiron in blurs of color and force. Some crossed galaxies in heartbeats, folding space as they moved. Others vanished entirely, their speed too great to perceive. The sound of displacement thundered through the void.
Apeiron ran.
At human speed.
His breath burned within seconds. His legs protested immediately, muscles screaming as he forced himself onward. Each step felt meaningless against a distance that dwarfed comprehension, yet he took them anyway. Sweat soaked through his clothes. His vision blurred. Still, he ran.
Thirty minutes passed.
For him, it felt like a lifetime.
Then space snapped.
The infinite collapsed.
Apeiron was wrenched back into the dojo, dropping to one knee as reality slammed itself back into place.
The others returned moments later stretching, rolling their shoulders, speaking in low voices. Some laughed quietly. None of them looked strained.
Apeiron stayed where he was.
His chest heaved. His legs shook beneath him.
"Theseus addressed the class without looking back. "The warm-up is over. Find a partner."
The training resumed.
Sparring.
Technique drills.
Live combat.
Apeiron was hurled into walls hard enough to crack stone. Driven to the floor again and again. Struck until his vision swam and the world rang in his ears. He faced beings whose power eclipsed his own so completely they held back not out of respect, but pity.
Some of them smiled as they did it.
Each blow was a reminder of how far behind he stood.
Hands raised, breath ragged, Apeiron faced his next opponent a warrior who vanished and reappeared in flashes of light. Pressure points flared white-hot as strikes landed faster than his eyes could track. His body slammed into the ground before he could recover.
Another opponent followed. The earth itself peeled away beneath their feet. Stone rose and shattered as fists came down like falling mountains. Apeiron dodged where he could, rolled where he had to barely staying alive.
By the end, he could no longer stand straight.
His eyes were blackened.
Skin split and swollen.
Hands trembling uncontrollably.
The class was dismissed.
Theseus approached, arms crossed, his expression unreadable.
"I teach many classes," he said evenly. "If you're serious, you'll attend all of them." A pause. "Unless you've changed your mind."
Apeiron forced himself upright. Pain screamed through every muscle, every joint, every breath.
"I haven't," he said.
His body was broken.
His spirit was not.
Theseus turned and walked toward the next hall.
Apeiron followed.
Apeiron kept going.
From class to class, hall to hall, discipline to discipline, the result never changed. He finished last every time. He was struck down, thrown aside, mocked openly for being the weakest one there for being human. By the end of the day, his body was a map of bruises and swelling, every movement paid for in pain.
When they finally returned home, Apeiron barely made it through the door.
He collapsed onto the floor, boots half-off, breath ragged, hands shaking as he tried to push himself upright. Every muscle screamed. Every joint burned.
"I can't," he said aloud, his voice breaking. "I can't do this every day. I'm nowhere close to them. I never will be."
His fists clenched, nails biting into his palms.
"I can't avenge my parents," he whispered. "I can't save anyone. I'm just… weak."
The room stayed quiet.
Then, a soft chime broke the silence.
Apeiron froze. With trembling hands, he reached into his bag and pulled out a small square device smooth, etched with faint lines where magic and technology intertwined. The surface glowed.
Pandora's image appeared, gently projected into the air.
"Are you there?" she asked. "Can you see me?"
Apeiron let out a weak laugh, tears slipping free.
"Yeah," he said softly. "I can see you."
They talked at first about small things how much they missed each other, things that didn't matter and somehow mattered the most. He told her about the classes. She teased him gently, the way she always did. For a moment, the pain faded.
Then his voice cracked.
"I don't think I can do it," he said quietly. "I don't think I can be a warrior. Or the best at anything." He swallowed. "I wanted revenge. I wanted to make things right. But maybe I'm just… destined to be nobody. To be nothing."
The tears came then, freely, uncontrollably.
Pandora's expression softened.
"Don't say that," she said. "You may be human, but your heart is larger than anyone I know." Her voice was steady, certain. "You feel more deeply. You endure more quietly. That matters."
She smiled, warm and unwavering.
"I believe in you."
Apeiron wiped his eyes, breathing slowly.
"…You're right," he said at last. "I can't do it like them. That doesn't mean I should stop." He exhaled. "I just have to find a way that works for me. As long as I try my hardest, every day… I hope it comes true."
His voice steadied.
"I'm not giving up."
They stayed connected long into the night, their voices low and familiar, a quiet anchor against the dark. Eventually, exhaustion claimed him.
Apeiron fell asleep listening to her breathe.
Each word she had spoken lingered with him, filling his will, holding him together.
