For thousands of years, the starry sky that humans have looked up to is an eternal picture. The position of each star is fixed by divine law. The rise and fall of the empire and the destiny of individuals are all predicted by this "Star Map of God". The right to interpret the star chart is in the hands of the "Oracle". They are the maintainers of order and the spokespersons of destiny.
However, the young royal star mapmaker, Kai, a genius who was skeptical of oracles, discovered a "wandering star" that should not exist during a routine observation. The appearance of this star was like a drop of ink falling into clear water, disrupting the order of the entire sky and shaking the foundation of faith on which the empire relied for its survival.
Kai's behavior was labeled as "heresy", and he became the target of the Oracle's full pursuit. On the way to escape, he met a cynical old scholar who was pursuing the truth of history, and a mysterious nomadic girl from the desert who dictated the ancient legend of "visitors from outer space".
