He is the ruler of the Domain of Death and the father of Erinys. He was a minor figure in Greek mythology, often referred to but rarely appearing in person. Thanatos isn't mentioned in the game itself, but it's curious to notice that, for being a Primordial god , it is very likely that he participated in their war, which was mentioned at the intro of the game. The war was so vicious that almost all of the Primordials died during it, and Thanatos was one of its few survivors, which is also a proof of the great strength and power he possesses, even against other Gods. It is possible that, since many Gods were dying in the war and he is the God of Death, he was getting stronger at each time another God perished. In the Multiplayer, when a warrior respawns after death, the announcer may sometimes say "Thanatos will have to wait". Thanatos is described as an ancient and fearsome God, who predates the cycle of life and death, and is the reaper of all souls. Zeus sent the siblings to capture him and hide the Spartan where he wouldn't be found. After Kratos , Deimos' brother and the real Marked Warrior, killed Ares and became the new God of War, he was summoned by his mother Callisto , who told him his brother was alive.
