Yeon-woo had spent the last five years trying to move on from the disappearance of his twin brother.
Then, one day, his brother’s pocket watch—a final memento—found its way back to him.
And hidden within it was a diary.
"By the time you hear this, Brother, I will likely no longer be of this world."
The Obelisk, the Tower of the Sun God, stands at the crossroads of countless dimensions and universes.
It was there that his brother climbed, only to be betrayed and forced to close his eyes forever.
Armed with the truth and the diary his brother left behind, Yeon-woo begins his ascent of the Tower.
"From this day forward... I am Cha Jeong-woo."
