The sun crept over the horizon of
Aurora Spritian, casting its warm golden light over the mansion on the hill.
The morning air was crisp, carrying with it a sense of anticipation and
tension. Today was the beginning of their most intense training yet — the
mastery of energy.
The battle arena stretched out like a
coliseum, surrounded by advanced technology and shimmering energy barriers. The
teams gathered, their faces set with determination. Zyren, Akira, Akio, and
Hiroshi stood ready, the dark tendrils of Halcyon Raven Flux flickering faintly
around them. Kyra, Mirae, Taro, and Kaito were equally focused, their aura
carrying the icy calm of Cyrex Snow Flux. And then there was Kyrin's team —
Kyrin, Senjuro, Rin, and Blaze — the ones who had shocked everyone the day
before by harnessing all ten types of energy.
But while they stood waiting in the
arena, Veyvron and Syvaren observed from the control cabin high above. The room
was filled with monitors displaying the trainees' vitals and energy readings,
but Veyvron's eyes were locked on the four who had defied all logic.
"Only we've ever been able to master
all the different energy natures," Veyvron said quietly, his voice serious.
"And now these four kids have complete control over them. Do you know what that
means, Syvaren?"
Syvaren folded his arms, his sharp
gaze following his brother's. "Maybe they have cores?"
Veyvron's expression darkened. "I'm
sure of it — at least for Kyrin. I've sensed it in him for a long time. But
yesterday… when their energies combined in that storm, I caught faint traces of
core energy from all four of them. If I'm right, they might all possess cores."
Syvaren let out a slow breath. "Then
they're more dangerous — and more powerful — than we ever imagined."
The Core Theory
The cores were a rare and almost
mythical phenomenon. Only a few assassins in the history of the ten nations had
ever possessed them. A core was a crystallized form of pure energy housed
within a person's soul, allowing them unparalleled control and affinity over
the elemental forces of the world. Both Veyvron and Syvaren had developed their
cores through brutal training and sheer willpower and combination of the ten
energies — but if these four had them naturally…
"They'll need to learn control,"
Syvaren said. "Because if their cores awaken fully before they're ready, it
won't just destroy them — it could destroy everything around them."
Veyvron nodded. "Then let's make sure
they're ready."
Training Begins
Veyvron's voice boomed over the comms,
breaking the quiet in the arena. "Today, you'll begin your energy control
training. Each of you has been gifted with incredible power — but power without
control is destruction. Let's see how well you can handle it."
The first test was simple: energy
manipulation. The teams were tasked with forming their respective energy into
stable constructs. Zyren's team created shadowy weapons — swords, daggers, and
spears made of the Halcyon Raven Flux's eerie dark energy. Kyra's team summoned
crystalline ice formations, the Cyrex Snow Flux swirling in delicate but deadly
shapes.
But when Kyrin's team stepped forward,
the entire arena shifted.
Kyrin's palm opened, and flames of
Solarflare Ember Flux danced alongside the biting cold of Cyrex Snow Flux. Rin
created shimmering constructs of Radiant Horizon Flux while Blaze's hands
sparked with Viridian Cyro Flux's crackling energy. Senjuro wove all of them
together, creating a sphere of pure, balanced light and shadow.
The arena trembled under the sheer
force of their combined power.
Veyvron exchanged a look with Syvaren.
"It's not just their cores," he said. "It's their synergy. They complement each
other perfectly."
A Dangerous Discovery
As the day's training progressed, it
became increasingly clear that Kyrin's team was different. Their ability to
switch between energies and combine them with ease was unlike anything the
instructors had seen. But there was something else — something beneath the
surface.
When they pushed their powers to their
limits, strange energy signatures began to appear — deeper, older, and more
dangerous.
During a sparring match, Blaze
unleashed a devastating wave of Lumin Emberlight Flux, and for a split second,
the energy around him shifted into something darker — something primal.
Veyvron's eyes narrowed. "Did you see
that?"
Syvaren nodded. "It's their cores.
They're starting to awaken."
The Warning
After training, Veyvron gathered
Kyrin's team in a private chamber. The room was dimly lit, the atmosphere heavy
with unspoken tension.
"You're all progressing faster than we
ever expected," Veyvron began, his voice calm but serious. "But there's
something you need to know. The power you're accessing — it's tied to something
deeper inside you. Your cores."
Rin tilted his head. "Cores?"
Syvaren stepped forward. "A core is a
crystallized form of pure energy within your soul which is connected to an artificial
core connected to your Solar Plexus. Only a handful of assassins have ever
possessed one — and we believe all four of you do."
Kyrin's eyes widened. "But… what does
that mean?"
"It means you're more powerful than
anyone else in this nation," Veyvron said. "But it also means that if you lose
control, that power could consume you — and everything around you."
Senjuro crossed his arms. "So what do
we do?"
"Tomorrow," Syvaren said, "we begin
the next stage of your training. You'll learn not just to control your energy —
but to control your core. And you'll need to master it fast."
"Why fast?" Blaze asked.
Veyvron's expression darkened.
"Because there are forces moving against us — and they won't wait for you to be
ready."
The Road Ahead
As they left the chamber, the weight
of their newfound knowledge settled heavily on their shoulders. They were no
longer just trainees. They were the future of Aurora Spritian — and the only
ones who could stand against the darkness rising in the world.
And far beyond the hilltop mansion, in
the shadows of the nine nations, that darkness was already beginning to stir.
The next morning, the air around the mansion felt
heavy with anticipation. Kyrin and his team had been summoned to Veyvron's
cabin — and they all knew this was going to be different. There was a sense
that something important was about to happen. As they entered, they found both
Veyvron and Syvaren already waiting, their expressions serious.
Veyvron gestured for
them to sit and spoke in a calm but commanding voice. "Today, I'll be examining
your cores — and by understanding their nature, I'll know exactly how to guide
your training from here on."
The room fell
silent, and then Veyvron turned to Blaze first. "Let's start with you."
Blaze stepped
forward, removing his mech suit and then his shirt. The faint glow of his core
shimmered just beneath his skin — a deep, burning red, pulsing like a
heartbeat. Veyvron's eyes narrowed as he studied it.
"This… is the Crimson
Aetherheart Core," Veyvron said with clear admiration. "It's an
extraordinary core — rare and powerful. Your core allows you to channel the Crimson
Phoenix Flux, but its potential goes far beyond that. Once it's fully
awakened and fused with the 10 energies of Aurora Spritian, you'll be able to
create an Ascendant Phoenix Form— a form of
unimaginable power and destruction."
Blaze grinned, the
fire in his spirit clearly mirroring his core. "I like the sound of that," he
said, clenching his fists.
Next, Veyvron
turned to Rin. He stepped forward confidently, and removed his jacket. The
soft, radiant light of his core shimmered with a silvery-blue hue.
"This is the Celestia
Mirage Core," Veyvron announced, his voice thoughtful. "It's a core of
illusion and reality, of light and reflection. You haven't even scratched the
surface of its true power yet. When this core reaches its peak and merges with
the 10 energies… you'll be capable of creating Planetary
Devastation — the
ability to conjure catastrophic gravitational forces and reshape entire
battlefields. A truly terrifying gift."
Rin's eyes
widened, taking in the weight of those words. "Planetary Devastation…? You're
serious?"
"Deadly serious,"
Syvaren added. "Your core's potential is unlike anything we've seen in
generations."
Then came Kyrin's
turn. He stepped forward, his heart pounding in his chest. The glow of his core
was intense, a swirling storm of energy crackling just beneath the surface.
Veyvron's eyes lit
up. "This… this is the Aetherstorm Catalyst Core," he said, his
voice filled with awe. "A core designed for warriors. This core grants you inhuman
stamina, allowing you to fight far beyond the limits of any normal
being. It also takes your firearm and melee mastery to unprecedented heights —
every strike, every shot will be faster, stronger, and more precise. You'll
become an unstoppable force on the battlefield."
Kyrin felt a surge
of pride — and power — course through him. This was what he had always dreamed
of.
Finally, it was
Senjuro's turn. But the moment he stepped forward and removed his shirt, the
room shifted. The light from his core wasn't just a glow — it was a prism
of colors, radiating all the energies of Aurora Spritian. Both Veyvron
and Syvaren froze, their eyes widening in shock.
Veyvron's breath
caught. "Who… gave you that core?" he asked, his voice almost a whisper.
Kyrin frowned.
"Sensei… aren't cores developed spiritually inside the soul?"
"Yes," Veyvron
replied, still staring at the shifting colors of Senjuro's core. "But this…
this isn't an ordinary core. This is the Prism Aetherheart Core — and it once belonged to Valan
Krynn, the greatest assassin the world has ever known. He was my
cousin. This core… should have died with him."
Senjuro's face
grew serious. "You're right, Sir Veyvron. Five months ago, Valan Krynn came to
me — covered in blood, on the brink of death. He had been ambushed by Segrito
assassins, and even in his weakened state, he fought them off like a true
warrior. But his injuries were too severe."
The room fell
silent as Senjuro continued. "I took him into my home, tried to heal him — but
he knew his time was short. And in his final moments… he placed this core
inside me. He told me to carry his legacy — and that's when my journey as an
assassin truly began."
For a moment, no
one spoke. The weight of those words hung heavy in the air.
Syvaren broke the
silence first. "For a warrior like Valan Krynn to meet such a tragic end… it's
unthinkable. But Senjuro — you must understand — if he entrusted you with his
core, then he believed in you. He saw something in you."
Veyvron nodded,
his expression finally softening. "No wonder you were able to create that sphere
of combined energies. Only the Prism Aetherheart Core can wield all 10
fluxes in perfect harmony. Senjuro… you're more than just a student. You're the inheritor
of Valan Krynn's will."
Senjuro clenched
his fists. "I'll fight until my last breath to honor
his legacy," he vowed, his voice filled with conviction.
The room stayed
silent for a few more moments before Veyvron finally spoke again. "Your
training from here on will be different. Now that we know the true nature of
your cores, we'll help you awaken their full potential. You'll learn not just
to control the 10 energies — but to fuse them with your core's unique abilities.
You'll become the protectors this world needs."
Kyrin looked at his friends — at the determination in their
eyes — and he knew this was just the beginning. The real
battle was still ahead.
