|“||Here is where the souls of the wicked are tortured in the pits of Tartarus, the wailing and agony of the damned, resonated deep throughout the bowels of the Underworld.||”|
In Greek Mythology, Tartarus was the darkest depths of the Underworld. It was where the souls of the evil were sent to for eternal torture, and was where Zeus imprisoned the Titans. In Greek Mythology, Tartarus was a part of Gaia, near the regions of her stomach, while in other variations of Mythology, Tartarus was also a Primordial like Gaia, also oldest child of Ouranos and Gaia. He made love to Gaia as well and Gaia gave birth to Typhon as a result.
Tartarus was envisaged as the opposite of the sky, an inverted-dome that lain beneath the Earth. Together, the Ouranion-dome and Tartarean-pit enclosed the entire cosmos in an egg-shaped or spherical shell.
In God of War: Chains of Olympus, Kratos was defeated by Charon, and subsequently thrown into Tartarus. As he attempted to make his way out of the depths, Kratos fought his way through hordes of enemies, came across the prison of the Tartarus, and obtained the Gauntlet of Zeus, which aided his escape.
In order to craft a special weapon for the Spartan Warrior, Hephaestus told Kratos to retrieve the Omphalos Stone. The stone, however, was said to dwell deep within the Pit of Tartarus, deep below The Forge. In the caverns, on his way his to the doors, Kratos witnessed the freed souls of the Underworld in search of their redemption that was nowhere to be found. Then, Kratos reached the Gates of Tisiphone, which he needed to solve the puzzle of the doors that lead him to the Pit of Tartarus. He then battled his way through its darkest depths, until he ultimately came face-to-face with Cronos. After a vicious battle, Kratos slew Cronos, retrieved the Omphalos Stone, took it to Hephaestus, and received the Nemesis Whip.
- In God of War III, Tartarus was limited by an infinite stone ceiling, but there was a big hole on a part of it. Sunlight entered Tartarus through it, which indicated it lead to the surface and was an exit to the Mortal World. It was unknown why it existed or if it was made by someone, but it seemed to be large enough for a God or even a "small" Titan, like Typhon, to go through and seemed to be very old. It may have been used by the Gods who threw the Titans into Tartarus, for example. That hole could be seen by reading the book inside Tartarus, near Cronos location, and using the camera to look up.
- It's revealed in God of War III, that Tartarus was actually the legendary battleground between the Gods and the Titans, though in God of War II, Atlas claimed the Great War forged the landscape of the Mortal World and not the Underworld.
