“The oldest stories are written in the stars, stories of time before man and gods. When titans ruled the earth. The titans were powerful but there reign was ended by their own sons; Zeus, Poseidon and Hades. Zeus commanded his brother Hades to create a monster so strong it could defeat their parents and from his own flesh. Hades gave birth to an unspeakable horror, the Kraken. 
Zeus became King of the heavens.

 Poseidon, King of the seas and Hades tricked by Zeus was left to rule the underworld in darkness and misery. It was Zeus who created man and man’s prayers fed the god’s immortality. But in time, mankind grew restless, they began to question the gods and finally rise up against them. Into the world, a child was born, a boy who would change everything. His name, PERSEUS.

I’m a big fan of medieval tales/movies with this kind of intro.❤
