Underworld

The King of the Underworld
Hades, the oldest brother of Zeus, is the ruler of the Underworld and all of iyts inhabitants. Hades is the weakest of the three brother kings but is certainly not the stupidest in my opinion. I beleive that he was the hardest of the gods to vanquish in the God of War series together. Hades weilds the Claws of Hades; two cruel looking hooks with with chains that are quite similar to the Blades of Exile that Kratos uses throughout most of God of War 3. These hooks have the power to bring cursed souls to the battlefield to help their summoner.

Hades' Fall
Hades falls to the ever-growing-strong Kratos by having his own souls ripped out with his own weapons. With Hades' souls Kratos is able to swim to river Styx unharmed by the souls that stole his power in the beginning of the game.

The Claws of Hades
The Claws of Hades are very much like the Blades of Exile. But the Claws seem to have a mind of their own when it comes to battling. The Claws are like a second fighter raging alongside Kratos in many ways.

The Underworld
The Underworld is where souls go after they die.

They either became monsters to wonder back into the world of the living, soldiers for Hades' army, or tortured souls to wonder forever in the never ending world of the dead to always hear the melody of the damned and cursed.

Kratos travels to the Underworld in every main game. First when he was murdered by Ares and climbed out of the gravedigger's hole. Second, when Zeus killed him and he was pursuaded by Gaia to live again. And third, when he fell from Gaia's back and had a chat with the ghost of Athena. Hephaestus once in a while had Kratos go into the Underworld to retrieve a stone that could help Kratos battle Zeus.
