In Rune Continent, magic flows like air, but it also breeds an abyss that swallows everything. The "rune" that drives all this is both power and the source of destruction.
The Holy Empire of Demacia maintains its decadent order with an iron fist, and the aloof protoss enjoys playing with the world. Caesar, a college student, accidentally awakens his ancient bloodline and is chosen as the "Watcher of the Void". As his power began to get out of control, he embarked on a journey to solve the "nightmare" and formed an alliance with the cursed little fox Ahri, the frost witch who was hunted by the tribe, and the mysterious rune collector Ryze.
The broken crown, the blood-stained runes, and the eyes staring at the end of the abyss...
As Caesar gets closer to the truth, he discovers that the so-called prophecy of "saving the world" is just another sacrifice set by the ancient gods.
This young man who once struggled at the bottom unknowingly stood at the center of the storm. Should he become an empty vessel without emotion, or should he retain his love and will and risk the end of all things?
The abyss has opened its thousand eyes, and Caesar's heart is shaking.
This time, what the Watchers want to protect is not only peace, but also the final right to "choose to be yourself."
The story is divided into six volumes: Awakening of the Void, Advent of the Dark Moon, Set Sail of the Origin Plan, Shattered Throne, Final Dawn, and Era of White Clothes. Each volume contains different themes and plots.
