Primordials

The Primordials were the first race of beings and deities that came into existence, predating the Gods and Titans. They were astronomical in size and their appearances were elemental and cosmic, bit similar to the Titans, though they bore a more humanoid appearance.

The in-fighting among the Primordial race resulted in the creation of the world and universe, and also caused the birth of the Furies.

In the God of War Series
It's said that before the Titans and the Gods, a war broke out between the Primordials, the beings who forged the Earth. Their war was so massive it caused many natural disasters around the world, and from the rage and madness of their war, the Furies were born.

The best known Primordials are Chaos, Gaia, Ouranos, Nyx and Tartarus. Morpheus, Charon, Thanatos and the Sisters of Fate would also be considered to be Primordial deities.
