Aeris continued with a grin and with a look of excitement. “...through combat.”

Cael blinked rapidly. “Wait—what? Why?!”

Aeris’ eyes glittered like starlight, full of mischief and hunger.

“Ryu.” Her mana began rising, slow and deliberate. “If you want the information on the Fallen Luminaries…”

Astral patterns started swirling around her feet.

“…you’ll fight me in the Arena.”

The tension in the Guild spiked instantly.

Ryu stared back flatly.

“Fine,” he said. “don’t cry when you lose.”

Aeris smiled, pure and bright — the smile of someone thrilled.

“Try me.”

The Elven Guild rumbled with anticipation.

The battle was inevitable.

And the entire capital felt it.

The Guild Master of the Elven Guild — Thalanor Eryndale comes to look at who’s causing all this commotion but sees the man he trusts — Ryu Aetherion. Thalanor is quite a good-looking elf.

Thalanor greets Ryu with an excited tone. “Ain’t you good, Ryu?”

Ryu replies plainly. “Yes.”

Thalanor with his voice playful “Don’t be like that. It’s been centuries since we’ve seen each other.”

Thalanor stepped closer, brushing a hand through his silver-white hair, his emerald eyes sparkling with the same youthful arrogance he had even as a “young” elf centuries ago.

“You vanish for ages,” Thalanor said, clapping Ryu on the shoulder with the casual familiarity of someone who truly could, “and the first thing you do when you stroll back into my Guild is cause a celestial-tier commotion?”

Ryu shrugged. “Wasn’t my intention.”

Aeris snorted lightly behind them. “It absolutely was your intention.”

“It absolutely was not,” Ryu corrected, monotone.

Cael watched the exchange like some fever dream, eyes darting between living legends.

Thalanor finally noticed him and Yoru.

“Oh—new faces.”
He leaned in to Ryu. “You actually brought company? You? Mr. I-travel-alone-for-800-years Aetherion?”

Ryu ignored that completely. “Aeris wants to fight.”

“She always wants to fight.” Thalanor waved a hand.
Then his grin sharpened.
“And she only challenges someone if she thinks they’re worth drawing blood from.”

Aeris’ eyes narrowed in pleased agreement. “Flattering, but unnecessary.”

“It was not a compliment,” Thalanor replied.

The tension between the three was nothing new—Cael could tell instantly there was history here, old and tangled, like three constellations whose paths constantly crossed whether they wanted them to or not.

Thalanor clapped his hands once.

“Well then! If my strongest Arbitress wants a duel with my oldest headache, who am I to deny the entertainment? The Arena is open.”

Aeris’ mana sharpened. “I’m ready now.”

“Of course you are,” Ryu sighed.

Thalanor leaned in, whispering loudly,
“Try not to level the arena this time.”

“That was one time,” Ryu replied.

Thalanor raised a brow. “It was ten times.”

“Semantics.”

Yoru tugged Cael’s sleeve. “Come. You’ll want to see this.”

Thalanor gestured toward a wide corridor lined with glowing runes.

“This way. The Arena awaits.”

Aeris walked past Ryu, her shoulder brushing his as she moved ahead—light, deliberate, and very clearly intentional.

Ryu clicked his tongue but followed.

The crowd parted instinctively.

Every elf in the Guild felt the rising pressure—the kind that only came when two monsters of the old era prepared to clash.

Thalanor’s grin widened as he stepped back, studying Ryu with an appraising tilt of the head—like he was reacquainting himself with the shape of a myth he once knew personally. “Centuries,” he repeated, a touch of nostalgia beneath his lively voice. “You’d think immortality would make time feel shorter. It doesn’t. Not when an old friend disappears off the face of the world.”

Ryu lifted an eyebrow. “You didn’t look too devastated.”

Thalanor placed a hand on his chest dramatically. “I wept every night.”

Yoru snorted. “He absolutely didn’t.”

Thalanor snapped back, “Let me have my moment!”

Aeris watched them with faint amusement simmering beneath her poised exterior. To her, this banter was familiar—natural. Ryu slipping into old social grooves he hadn’t touched in ages was something she hadn’t expected to enjoy, yet she did.

The Guild hall, however, remained taut with tension. The elves around them had resumed their tasks—but only superficially. Eyes still darted toward Ryu, toward Aeris, toward the Guild Master, waiting, listening, afraid to breathe too loudly in the presence of beings who could individually shift the balance of nations.

Thalanor gestured toward the main corridor. “Well then! Since Aeris insists on tradition—”

Aeris glanced away coyly.
“It’s not tradition. It’s… personal preference.”

Ryu sighed. “You just want to punch me.”

“I want to measure you,” she corrected. “Punching is optional.”

Cael whispered under his breath, “That’s somehow scarier.”

The Guild Master waved for them to follow.
“Let’s take this to the Arena before you two accidentally demolish my lobby.”

“You two?” Ryu repeated. “I haven’t done anything.”

“Not yet,” Thalanor retorted. “Give it five minutes.”

Aeris nodded in agreement. “Two minutes.”

“…Tch.”

They moved as a group, the corridor before them stretching out in an elegant arc crafted of moonstone, star glass, and drifting mana-lights. The architecture was ancient, but not old; familiar, but constantly renewing itself. Elyndoriel did not simply maintain structures—they allowed buildings to grow, to evolve, like living organisms of magic and artistry.

The footsteps of the group echoed softly, giving the atmosphere a sense of ceremony.

The Walk to the Arena

Cael stayed close to Yoru, still trying to process everything.

“Do… do people normally challenge Ryu like this?”

Yoru looked amused. “If by people you mean idiots or immortals with no sense of self-preservation, then yes.”

Cael swallowed. “And Aeris is…?”

“One of the few who can survive it,” Yoru answered. “Barely.”

“Barely?” Cael repeated, horrified.

Yoru shrugged. “Ryu holds back… aggressively.”

They passed under archways glowing with astral script—most of it written in a strange, elegant language Cael didn’t recognize. Ryu briefly glanced at one of the runes.

He muttered, “I designed that.”

Thalanor snapped his fingers. “Ah, I knew I recognized the structure! You made those glyphs in your ‘boredom phase,’ didn’t you?”

“Everything was my boredom phase,” Ryu replied.

Aeris gave him a side-eye.
“And yet you still say you’re not dramatic.”

“I am not.”

“You built a system of self-updating runic architecture because you were ‘slightly bored.’”

Ryu didn’t respond.

Cael tilted his head. “You can do that?”

Yoru leaned toward him with a whisper. “He once created an entire sub-era of magic because he didn’t like how long spell incantations were.”

Ryu clicked his tongue quietly, which only confirmed it.

Thalanor chuckled. “Well, regardless, your craftsmanship remains unmatched. The Arena is still one of the wonders of this capital.”

“And Aeris’ favorite playground,” Yoru added.

Aeris smirked, flickers of astral light gathering around her shoulders. “Guilty.”

Arena Antechamber

They stepped into an enormous circular chamber—the threshold before the Arena.

This was where challengers prepared.
Where legends took a breath.
Where fear and resolve coiled together.

Floating runic plates circled overhead like mechanical constellations. They hummed in recognition of Aeris’ presence, then dimmed out of respect for Ryu’s.

Thalanor gestured outward. “Beyond these doors lies Elyndoriel’s greatest battleground.”

A massive gate in front of them glowed, lines of astral mana pulsing like veins.

Aeris stepped forward, clasping her hands behind her back in a deceptively calm posture. “Ryu.”

Ryu looked at her.

She smiled faintly. “No rules. Yes?”

Ryu froze.
Thalanor froze.
The runes froze.

Yoru groaned loudly. “Aeris, for the love of the stars—NO.”

Cael flinched. “N-No rules?!”

Ryu stared deadpan. “Absolutely not.”

Aeris blinked innocently. “Fine. One rule.”

Ryu crossed his arms. “What rule.”

“No erasing the Arena.”

Ryu narrowed his eyes.
“That rule is insulting.”

“It is necessary,” Thalanor agreed instantly.

Aeris turned to the gate. “Besides, the Arena has been reinforced enough times that I doubt you could destroy it by accident.”

“By accident,” Yoru repeated. “Meaning Aeris KNOWS he could do it on purpose.”

Aeris didn’t deny it.

Ryu sighed. “Fine. One rule.”

Aeris' mana brightened.
The gate responded, activating with a low vvvmmm.

Thalanor clapped his hands once. “Excellent! Once both of you step inside, the Arena will fully manifest and lock.”

Aeris walked past Ryu, hips swaying slightly—the kind of movement that wasn’t meant to entice but ended up doing so anyway simply because she moved with such refined confidence.

She murmured as she passed:
“Try not to disappoint me.”

Ryu muttered, “You talk like you’re the stronger one.”

Aeris gave a small, lethal smile. “I talk like I’m the one who’s excited.”

Then she entered the Arena.

The Arena of Celestial Echoes

As Ryu stepped through the gate, the world expanded.

The Arena wasn’t merely large—it was colossal, a dome holding an artificial sky. Stars drifted overhead, forming patterns in real time. The ground shimmered with astral circuits, forming a combat grid older than all but the greatest elf historians.

Floating platforms orbited at various heights, gliding slowly like moons around a planet.

And at the center—

Aeris waited.

Her hair floated gently around her as astral motes danced in the air.

When Ryu entered, the dome sealed shut behind him with a thunderous wave of mana.

BOOM.

The entire capital felt it.

Elves across districts paused, looking toward the Guild’s dome.

Rumors already began spreading.
Speculation.
Fear.
Excitement.

Up in the audience stands—formed entirely of condensed astral light—hundreds of elves filed in, whispering intensely. Every pair of eyes locked onto the ancient sovereign and the astral prodigy facing each other on the arena floor.

Even higher above, in the central command balcony, Thalanor stepped into his own platform, arms crossed, an eager grin plastered on his too-pretty face.

Yoru sat cross-legged beside Cael, who was gripping the railing so tightly his knuckles had turned bone white.

Cael whispered, “Ryu… looks calm. Too calm.”

Yoru blew a puff of air. “That’s because he is calm. Ryu doesn’t get excited. He doesn’t get nervous. He just exists.”

A beat.

“While Aeris,” she continued, “is two seconds away from exploding into happiness.”

They weren’t wrong.

Aeris’ entire body glowed with barely contained anticipation. “Ryu.”

Ryu lifted a hand lazily. “What.”

Her next words fell like a divine proclamation.

“Don’t go easy on me.”

The Fight Begins

Thalanor raised his hand high above the crowd.

“BEGIN!”

AERIS MOVED FIRST.

Not a blink.
Not a breath.
Not a warning.
Pure astral acceleration.

Her body vanished into a streak of light.

BOOM—!!

The ground cracked where she’d been standing a fraction of a second prior. Astral light tore through the air like a meteor aimed straight at Ryu.

Cael yelled, “She’s so fast—!!”

Ryu lifted one finger.

One.

Single.

Finger.

A pulse of mana rippled outward like a minor heartbeat of the universe.

The astral streak bent violently off-course—Aeris twisted mid-air, twisting in a spiraling flip before landing lightly on a floating platform hovering ten meters above him.

She grinned.

Cael’s jaw dropped. “He… deflected her?”

Yoru nodded. “Ryu’s mana density is so absurd that half of Aeris’ attacks won’t even reach him unless he lets them.”

Aeris flicked her wrist.

Several floating runic orbs manifested behind her—astral stars.

With a soft breath, she intoned:

“Astral Invocation: Starshower Convergence.”

The orbs exploded into beams of light that rained downward like a barrage of celestial arrows.

They moved fast.
Too fast for anyone normal to track.
Even Cael could only perceive streaks of light.

Ryu lifted his hand slowly—

And the entire barrage broke apart into harmless dust before touching him.

Aeris shivered in delight.

“Oh, I missed this.”

Cael asks, “H-How did Ryu do that?!”

Thalaron and Yoru reply in sync. “He uses the same composition to cancel the spell used by the other person.”

Cael is in shock. His mouth agape. “W-Wait, really?! Is that even possible?!”

Thalaron “Yes, not for everyone.”

Aeris Gets Serious

She lowered her stance, palms tracing complex astral sigils into the air.
A constellation circle materialized behind her—twelve points connected by shifting lines.

Ryu sighed. “The Twelvefold Zenith? Already?”

“You expect me to warm up?”

“Most people do.”

“I am not ‘most people.’”

“Unfortunately.”

Aeris thrust her hand forward.

“Ascendant Constellation — Twelvefold Zenith!”

The twelve astral nodes behind her fired toward Ryu in a spiraling attack pattern. Each one carried enough power to rupture mountain stone.

Ryu waved his hand like he was dismissing a fly.

A spatial fold formed—a clean bend in reality.

The constellation attack crashed into the fold and vanished.

Aeris’ eyes lit up. “Good.”

Then she appeared behind Ryu instantly.

Her kick swung toward his head—a clean, elegant, lethal arc of momentum.

Ryu caught it with two fingers.

Cael choked on air. “He—he just—two fingers—?!”

Aeris smiled.
“Better than before.”

“You’re weaker than before.”

“Oh?” she tilted her head. “Compared to who?”

“You, two centuries ago.”

Aeris laughed, delighted. “Then make me stronger.”

She twisted, using her captured leg as leverage—pushing off Ryu’s hold, she launched herself into a spinning arc of astral force.

Ryu let her spin past, stepping aside casually.

Aeris landed in a low crouch, skidding slightly.

The arena ground beneath her cracked from the force.

She stood again—hair floating, eyes glowing, arcane constellations swirling around her like a living halo.

“I’m only warming up now.”

Ryu cracked his neck once. “Someone said they don’t need to warm uop. Well, whatever.”

Ryu Finally Moves

Aeris felt it—the instant shift.

Ryu stepped forward.

Just one step.

But the Arena trembled.

The stars above flickered violently.

Even Thalanor inhaled sharply.

Yoru leaned forward.

Cael’s blood ran cold.

Aeris’ smile widened into something unrestrained, almost predatory.

“Oh… yes.”

Ryu lifted his hand.

And space compressed around Aeris' position.

—!!

Aeris’ eyes widened. She teleported instantly, reappearing several meters away as the air where she’d stood folded inward like crushing glass.

Dimensional sorcery: Absolute Pride.

Ryu didn’t use sorcery.

He used authority.

Aeris’ excitement skyrocketed. “Try harder.”

“Don’t beg.”

Aeris threw her palms outward.

A surge of astral energy erupted from her body, forming a massive field of star-light—her domain.

“Astral Realm: Celestial Court!”

The arena transformed in an instant — Stars spiraled, gravity shifted, platforms realigned, constellations stitched themselves through the air, forming complex patterns.

Every floating platform multiplied—forming a labyrinth of astral moons swirling around Ryu.

The audience gasped.

Cael stumbled as gravity fluctuated.

Yoru placed a stabilizing hand on his shoulder. “Don’t fall. Aeris’ domain isn’t friendly to the inexperienced.”

“But how do we not—”

“Because I’m blocking half the effects.”

Cael paled. “That was HALF?!”

Ryu looked unimpressed. “This again.”
