Greece: Me, Ruler of Destiny!

Good news: I transmigrated.

Bad news: it's Greek mythology, and I'm unlucky Prometheus.

Even better news: a soul from another world has altered the trajectory of fate. He has become the only variable capable of changing the world, and he was born very early, so there is plenty that can be done.

So...

Things begin to spiral out of control.

Years later, Zeus is finally born, only to discover that everything has slipped beyond his control.

Prometheus: This time, you are the challenger!

Also known as [Whether Greece is chaotic or not, Prometheus has the final say], [The mastermind prophet, in command of divine oracles], [Starting by foretelling the twilight of the gods], [In Greece, I have many children and much fortune], [Zeus: I only hate being born at the wrong time].

(The author writes with guidance from Prometheus, so this is not random nonsense.)
