In God of War (2018), Kratos's wife is named Faye. She is already dead when the game begins, but her final wish drives the story: she wants her ashes scattered from the highest peak in all the realms.
Faye is the name Kratos and Atreus use for her during most of the journey. Later discoveries reveal that she was the giant Laufey, connecting the family to Jötunheim and to the wider conflict involving the Norse gods. The game keeps this identity hidden for much of its runtime.
Faye is often confused with Freya because the names sound similar and Freya is another major female character in the game. They are different people: Freya is the former Valkyrie Queen and goddess, while Faye is Kratos's wife and Atreus's mother. The 2018 game also uses the name Laufey in its closing revelations and related lore.
