Ares' Sword was the weapon used by the fallen God of War, Ares.
God of WarEdit
Ares used this sword in the final battle with Kratos, but he underestimated the Ghost of Sparta and was impaled through the chest with the Blade of the Gods. The sword had a slightly larger role in the God of War novel, as it was used to kill the god instead of the Blade of the Gods, which was never mentioned. This would leave a plot hole, as Atropos attempts to destroy the blade in order to change Kratos' fate in God of War II.
