CENTURIES AGO
There was a time when Heaven and Hell knew nothing but war.
NovelToon
For thousands of years, the two realms clashed over a single place
THE LAKE OF ETERNAL PEACE
NovelToon
A sacred lake said to possess the power to stabilize the balance between all realms. Neither side was willing to surrender it, believing that whoever controlled the lake would determine the future of existence itself.
Heavan raised it's holy fire and the underworld answered with eternal flames
Cities Crumbled, Kingdoms Vanished Entire races were caught between a war they had never wished to fight.
THE ENDLESS WAR
NovelToon
That's what History named it..A War which showed no sign of ending even if the world turned upside down and round
Yet it did.
Not through a conquest or surrender but through two people who chose peace over pride..
The Greatest Archangel which Heaven has produced and 27th Prince of Hell
LLEWYN KILYZIAH and KAIROS VEN ALVAREZ

The Era of VYlTHRIS
NovelToon
A land where angels and demons lived beneath the same sky, Where heavenly gardens stood beside infernal forests,Where halos and horns were no reason for hatred.
For centuries...Vylthris remained the foundation of peace.
A kingdom admired by Heaven, Respected by Hell and feared by anyone foolish enough to threaten it.
..
Of course...
Every peaceful kingdom needed at least one walking disaster.
And Vylthris had its own Disaster
The youngest , most beloved child of the royal family someone for who people prayed wouldn't wake up before noon.

The sky above Vyltheris was glowing an alarming shade of crimson.
NovelToon
Half the training courtyard had been blown apart.
Angelic runes were shattered, demonic flames burned across the marble ground, and several terrified angels were currently flying away from a rampaging infernal beast.
In the middle of the chaos stood Vion
The enormous creature roared.

Ten minutes later.
ROYAL PALACE OF VYLTHRIS
NovelToon
Vion stood in the middle of the massive throne hall with his hands behind his back, sweating
Unfortunately, It wasn’t working.
In front of him stood two very powerful and very irritated beings.
His parents.
The King of Hell, Kairos Ven Alvarez, sat lazily on the throne, long legs crossed, looking far too amused for the situation.
NovelToon
Beside him stood Llewyn Kilyziah-Alvarez, his golden eyes narrowed in pure disappointment and anger

Pain.
That was the first thing Vion felt.
Not physical pain, but the uncomfortable sensation of his entire existence being squeezed through a portal.
THUD
Vion crashed face-first onto solid ground.
CHOI SEONG-HUN : VION
CHOI SEONG-HUN : VION
Ow..
He slowly pushed himself up and looked around.
Tall gray buildings.
Bright neon signs.
Strange metal vehicles rushing past.
And humans everywhere.
Vion stared blankly.
CHOI SEONG-HUN : VION
CHOI SEONG-HUN : VION
This place looks depressing..
A few nearby pedestrians glanced at him strangely before continuing on their way.
Vion dusted off his clothes and sighed dramatically.
CHOI SEONG-HUN : VION
CHOI SEONG-HUN : VION
So this is Earth.
A faint glowing screen suddenly appeared in front of him.

Classroom 2-B.
The door slid open and the teacher walked in.
Behind him stood Vion.
The entire class immediately looked up.
Most of the students had dyed hair, piercings, or bored expressions.
Well so did Vion so meh..
