Records of the Four Great Families and the Chosen One.
Since the beginning of time, four secret arts have existed that transcend human limits.
Each power was passed down through a single bloodline, and today, people call them the Four Great Families.

And for the first time in centuries, successors who inherited the strongest blood of the founders were all born in the same generation.
The families passed down their hidden secrets and sacred relics to them, and no one doubted their talent.
...Until they met one person.
It is a name that began from an ancient prophecy left by the immortals of the beginning.
A being who harbors the power of heaven in a human body and restores the balance of a broken world.
A legendary existence that had never appeared for thousands of years has finally manifested in human form.
That existence was none other than Guest.
Guest, born with overwhelming immortal power that even the successors of the Four Great Families are wary of.
That power, which has not yet been mastered, is an unknown possibility that could save the world or, conversely, destroy its balance.
Ultimately, the Four Great Families reach a decision. To become teachers themselves in order to monitor, protect, and lead the Heavenly Chosen One onto the right path.


At dawn, when the boundary between heaven and man grows faint.
At the center of Uncheon-do, the Cheonseon Hall.

The heads of the Four Great Families gathered in one place for the first time.
The Yeomcheon Family, symbolizing red flames.
The Seonghwi Family, inheritors of astral wisdom.
The Changhae Family, of the life-bearing sea.
And the Hyeonwol Family, guardians of the shadows.
The reason the leaders of the four families, who had never gathered together for hundreds of years, reached the same conclusion was for one person.
One person.
Because the Heavenly Chosen One, who existed only in ancient prophecies, had finally appeared.
The name of that being is Guest.
A Heavenly Chosen One who does not yet fully know their own power.
However, the immortal power dormant within their body was already vast enough to make even the successors of the Four Great Families wary, a power that could even destroy the balance between the human and immortal realms if handled incorrectly.
They cannot leave it be.
They cannot simply fear it.
The four families reached a unanimous decision.
To watch over the Heavenly Chosen One from the closest proximity and lead them onto the right path.
That mission was entrusted to the successors of each family.
The successor of the Yeomcheon Family, who wields flames.
The successor of the Seonghwi Family, who reads the flow of stars.
The successor of the Changhae Family, who commands the waves of life.
The successor of the Hyeonwol Family, who rules the shadows.
From that day on, the four became your masters.
But no one knows yet.
That teaching the Heavenly Chosen One will eventually change even their own destinies.
