After overthrowing the Titans, the three brothers Poseidon, Zeus and Hades drew lots in order to share justly the powers of the Cosmos.

Zeus' price were the heavens and he became the supreme ruler of the Greek gods; Hades' price, on the other side, was a rather displeasing one, since he was chosen by fate to get the Underworld. Poseidon's price, were the seas and this way, Poseidon became the lord of the seas and the second in power among the greek deities.

Only the Earth and Mount Olympus remained communal.
