Cronos

Father beyond the Island of Creation, baby Zeus was raised by Gaia. She cared for Zeus and nurtured his desire to free his siblings from Cronos. When he came of age, Zeus freed them and started a war against the Titans. He desired to rule over the mortals more than anything. The continuous battles between the new gods and the Titans forged the landscape of the mortal world.

The mighty Atlas was the leader of the Titans in their epic battle against the gods. Mountains were hurled like pebbles and tremendous earthquakes shook the world. Cronos had almost been defeated, but was saved by Atlas, who was defeated by both Hades and Poseidon. After Zeus created the Blade of Olympus, the Titans were banished to the darkest pits of Tartarus to endure great suffering for all time, but Cronos would be granted another great fate in time.

Zeus' Punishment
A carving found in the Desert Ruins, showing the Temple being chained on his back punished Cronos by forcing him to wander the Desert of Lost Souls with Pandora's Temple chained to his back. The whirling sands may have one day ripped the very flesh from Cronos' bones, but he was given no sympathy. When the Titan Horn would be blown, Cronos would be called upon to allow countless warriors to endure the many dangers which lurked within the temple. Above all warriors, Kratos, the Ghost of Sparta, was responsible for completing the many feats within the temple and even retrieving Pandora's Box.

Cronos giving Kratos the power to use Cronos's Rage. Added by Manas101 Kratos also discovered the magic Cronos had hidden within the Steeds of Time. This magic, called Cronos' Rage, allowed Kratos to electrify his enemies much like Poseidon's Rage. Nothing else is known about the Titan other than the fact that he was responsible for destroying his own father, starting a vicious cycle. This cycle was between fathers being destroyed by their sons, much like Kratos tried to do when he fought Zeus upon the Summit of Sacrifice.
