Titan

The Titans are a primordial race of divine beings that preceded the Gods. They were the children of Gaia and Uranus, and ruled over the universe after Kronos overthrew their father. Though the story of their rise to power is similar to that of the Olympians, the Titans were for the most part chaotic and corrupt, a fact most evident in their leader, Kronos. Humanity was created during their reign, but though it was called mankind's "Golden Age" it was not a time of peace for them. Gaia thus gave a prophecy that Kronos' tyrannical rule would be overthrown in the same way that he took power, with his children rising against him.

Trying to evade the prophecy of his downfall, Kronos devoured each of his sons and daughters as they were born, but his wife Rhea saved their final child, Zeus, by presenting Kronos with a stone wrapped in swaddling clothes instead. Hiding him away from the other Titans, Rhea ensured that Zeus would be raised in secret, and when he was grown he freed his brothers and sisters from their father's belly and stirred up a rebellion against the Titans

The war between the Titans and the Gods was called the Titanomachy. The Gods were victorious and threw Kronos and the other evil Titans into the depths of Tartarus, but spared those that took their side in the war, such as Helios and Prometheus, and gave them places in the new order. Those Titans that took a neutral stance in the conflict, like Oceanus and several of the Titanesses, were left alone, though many of their roles were taken over by Olympian gods.
