Perfect.
Here is an extended, highly detailed, lore-rich explanation of ALL your Authorities—told in-story, with worldbuilding, flavor, and mythic weight, just like a Campione light novel.
This chapter is long, atmospheric, and reveals the true power you gained from killing the four Children of the Gods.

CHAPTER 5 — "The Authorities of the God-Slayer"
Night had fallen over the ruins.
The moon hung low—too low.
Almost as if it were leaning in, curious about the new anomaly born into the world.
Satellizer had built a small fire from scattered temple wood. Isami was sleeping beside me, her head on my shoulder, exhausted beyond anything a normal human could endure.
I stared at my hand.
A mortal's hand…
…that now held the power of four Divine Children and a stolen flame meant for gods.
The firelight flickered across my palm.
"Are you going to tell me?" Satellizer asked quietly, sitting across from me in the warm glow. Her voice was steady but small—like she feared she might wake something dangerous inside me.
"Tell you what?"
"What you are now."
I closed my hand slowly, feeling golden lightning coil through my fingertips.
"…A Campione," I murmured.
The title tasted heavy on my tongue. Like iron and lightning.
Satellizer swallowed. "The god-slayer monarch… I never imagined I'd meet one… much less watch one ascend."
I said nothing.
Because the truth was, even I didn't fully understand what I had become.
But the Authorities inside me pulsed—alive, restless—whispering myth and power. They wanted to be recognized.
To be named.
To be used.
One by one, they awakened in my mind.

Authority One — Achilles' Radiance
The Body That Defies Death
A golden glow enveloped my arm as I closed my eyes.
The warmth was soothing—like sunlight on skin.
"Achilles…" I murmured. "His legend wasn't just speed. It wasn't just skill."
It was defiance.
A mortal who stood among gods.
A warrior who declared war on fate itself.
And through killing him, I inherited that same defiant radiance.
Satellizer leaned in, mesmerized.
"What does it do?"
I lifted my hand.
The air rippled—warped—like heat waves off desert sand.
"His invulnerability. His divine body. His speed. His willpower that ignores pain and fear."
But it was more than that.
It was an absolute advantage in any battle.
A constant passive divine armor.
A body that refused to break.
A life that refused to end.
But Achilles' legend had more depth.
"Achilles was only vulnerable at his heel because the story said so."
I touched my chest.
"Now that story is mine. My weakness—my heel—can appear anywhere depending on the battle, the enemy, the myth invoked."
"A shifting weak point…" Satellizer whispered. "That's… insanely unfair."
"For my enemies," I corrected.
Authority: Radiance of the Invincible Hero
→ Grants superhuman speed, strength, endurance, and near-invulnerability
→ Pain becomes meaningless
→ Weak point relocates depending on mythic context
→ Enhances other Authorities while active
My body felt impossibly light.
If I wanted…
…I could run across the sea.

Authority Two — Heracles' Twelvefold Wrath
Strength That Breaks Heaven
My hand closed around a rock by the fire.
I applied the tiniest pressure.
Crack.
It crumbled to dust falling between my fingers.
Heracles' Authority wasn't just brute force.
It was the power to overcome trials.
To grow stronger the more impossible the challenge.
To defy limits by destroying the meaning of limits.
"Issei… your aura changed," Satellizer whispered, eyes wide. "It's heavier. Like gravity is bending around you."
I felt it too.
Raw weight.
Raw potential.
Raw violence.
Heracles' Authority thrummed like a beast inside my bones.
"He was the greatest of the Greek heroes," I said quietly, staring at my clenched fist. "The strongest demigod to ever live. And now his strength lives in me."
But it wasn't simple strength.
Heracles' trials each carried symbolic power.
The Nemean Lion: Absolute toughness
The Lernaean Hydra: Regenerative rage
The Erymanthian Boar: Unstoppable charge
The Stymphalian Birds: Ranged destruction
The Augean Stables: Cleansing flood force
The Cerberus: Mastery over underworld beasts
And more.
All twelve trials were embedded in this Authority.
Authority: Twelvefold Wrath of Heracles
→ Strength that grows with struggle
→ Regeneration fueled by battle
→ Manifestation of aspects of Heracles' Twelve Labors
→ Can be stacked with Achilles' Radiance for overwhelming force
I exhaled deeply.
With this Authority alone…
I could destroy mountains.

Authority Three — Theseus' Labyrinthine Insight
Intuition That Sees Through All Deception
This Authority felt nothing like the others.
No weight.
No lightning.
No flame.
Just clarity.
Absolute clarity.
I opened my eyes—
—and the ruins around us shifted like a puzzle, every stone revealing history and purpose.
Isami's breathing patterns.
Satellizer's heartbeat.
The distance to every point of escape.
The location of the retreating gods.
The presence of Perseus far—far—away.
Everything was visible.
Not with sight.
With understanding.
"Theseus," I murmured, "wasn't the strongest. Or fastest. Or most divine."
"But he solved the impossible."
He navigated the Labyrinth.
Defeated the Minotaur.
Solved riddles left by gods and monsters.
He understood myth.
He understood fate.
And now—so do I.
Satellizer trembled.
"Issei… your eyes… they're glowing white."
"Don't worry." I blinked, dimming them. "I'm not going to use this to read your mind."
Although… I could.
Authority: Labyrinth King's Insight
→ Predicts enemy attacks and intentions
→ Sees through illusions, divinity, and fate
→ Understands myths and weaknesses instinctively
→ Creates mental "paths" to victory even in impossible fights
→ Grants limited manipulation of space within a defined area
In a fight…
…I could not be deceived.

Authority Four — Bellerophon's Sky Tyrant Dominion
He Who Rode the Heavens
The final Authority awakened with a rush of wind.
Not normal wind.
Sky wind.
The kind only experienced above the clouds, where mortals cannot breathe.
The fire around us dimmed as a great shadow passed overhead. Satellizer looked up with awe—Isami stirred in her sleep.
From the sky descended an ethereal Pegasus—wings glowing with divine essence, hooves touching the air itself.
Bellerophon's mount.
"My Authority," I whispered, as the beast bowed its head to me, "is dominion over the sky."
Satellizer's jaw dropped.
"You can fly?!"
"More than that."
Much more.
Bellerophon commanded monsters of the sky.
Tamed divine beasts.
Fought chimeras and serpent-birds.
And challenged Olympus itself.
His Authority granted:
Authority: Sky Tyrant Dominion
→ A Pegasus familiar bound to my soul
→ True flight—no magic circle, no wings needed
→ Control over air and pressure
→ Summon aerial monsters and divine beasts
→ Dominance over any battle fought in the sky
I lifted my hand.
The Pegasus dissolved into wind, becoming part of me again.
"Travel. Combat. Evasion. Summons… this Authority is terrifying," Satellizer whispered.
She wasn't wrong.
With this…
Olympus couldn't hide from me.

Authority Five — Prometheus' Stolen Flame
The Fire That Should Never Touch Mortals
My hand drifted to my chest.
To the pocket where the warm, pulsing glow of divine fire rested.
"Your last treasure," I murmured softly, remembering how Prometheus' dying child had forced it into my hands.
His last gift.
The Flame of Defiance.
The Flame of Knowledge.
The Flame of Rebellion against the gods.
This Authority was the most dangerous of all.
Unlike the others, I hadn't "taken" it.
It had been given.
"Prometheus… entrusted you with that?" Satellizer whispered.
She wasn't scared.
No—
she was terrified.
And she should be.
Because this Authority didn't grant strength or speed or flight.
It granted something far more world-breaking:
Authority: Fire of the Titan's Rebellion
→ Ignites concepts, not objects
→ Burns curses, fate, divine command, and mythic law
→ Can strengthen humans beyond mortal limits
→ Can create or destroy Authority pathways
→ Heals or resurrects mortals by stealing divine essence
→ Melts through godly invulnerability
→ Its use draws the attention of ALL pantheons
This was the fire that pissed off Zeus.
The fire that gave humanity civilization.
The fire that birthed the first heresy.
The fire that made Campione possible.
Satellizer's voice trembled.
"If Olympus finds out you possess that flame… they won't send Children. They'll send gods."
"I know."
"And if they fail… other pantheons will take interest."
"I know."
Her gaze met mine—fear and awe and something softer mixing in her eyes.
"Issei… you aren't just a Campione."
She swallowed.
"You are a threat to the divine order of the entire world."
I looked at my hand one last time.
Lightning.
Strength.
Foresight.
Sky dominion.
Rebel fire.
A weapon forged from myths.
A contradiction in human form.
A walking act of blasphemy.
I clenched my fist.
"For Isami," I said quietly, "for Satellizer… and for myself—"
Golden flames swirled around my arm.
"I'll use every Authority I have to crush anyone who tries to harm us."
The sky rumbled in response.
Somewhere far away—
a god opened his eyes.
