World Background: Astraeon
Astraeon is divided into five major factions:
1. Kingdom of Humans – Strongest army, sheer numbers
2. Elven Dominion – Masters of nature magic and speed
3. Dwarven Empire – Genius engineers, supreme weapons
4. Monster Clans – Mountain-dwelling tribes tied to shadows
5. Dark Legion – Army of the Dark Lord, once aimed to unite the world through force
Three hundred years ago, a prophecy foretold:
> "The Chosen Light will end the war…"
No one realized the Chosen Light carries a heart of light… in a body of darkness.

The Birth Secret of Shadow Shin
Mother: Elf Queen
Father: The Dark Lord
During a secret encounter in the Elf-Dark War, they fell in love.
When his mother became pregnant:
The Elves saw it as betrayal
The Darks saw it as weakness
A mysterious incident occurred: the mother and child vanished.
Everyone assumed they were killed by humans.
The truth?
His mother discovered her son's powers were more dangerous than all factions combined.
Fearful for his life—and for the world—she hid him in a shadowy village, teaching him control over his shadow and restraining his powers.
Before her death, she whispered:
> "If you can unite light and darkness… perhaps you can save our world instead of destroying it."

Shadow Shin is admitted, his true heritage unknown to anyone.

Beginning of the Story — Episode 1: Pilot
Shadow Shin lives a quiet life in a remote village… until a giant creature of the old Dark Legion appears.
For the first time, his latent power awakens uncontrollably:
Shadows move independently
The ground darkens
The monster retreats in fear
At that moment, a team from the Academy arrives, recognizing the "sign of the Chosen Light."
They decide to take him with them.
But… in the shadows, the Commander of Darkness watches from afar, whispering:
> "The heir of darkness… has returned."
Thus begins the war for his destiny.
