Many years have passed since Kratos took his vengeance against the Olympian gods, and he now lives with his young son Atreus in ancient Norway in the realm of Midgard. The game opens following the death of Kratos’ second wife and Atreus’ mother, Faye, whose last wish was for her ashes to be spread at the highest peak of the nine realms. Before starting their journey, Kratos is confronted by a mysterious man with godlike powers. After seemingly killing him, Kratos and Atreus begin their journey.
Reaching the Lake of the Nine, Kratos and Atreus encounter the friendly World Serpent, J�rmungandr, the last remaining giant. After running into impenetrable black mist which can only be extinguished with the Light of Alfheim, they receive aid from the Witch of the Woods to use the Bifr�st in order to travel to Alfheim and secure the Light. Upon vanquishing the mist and reaching Midgard’s peak, they overhear a conversation between the mysterious man, revealed to be Baldur, his nephews Modi and Magni, and the imprisoned M�mir. After they leave, Kratos and Atreus confront M�mir, who reveals that their goal is actually in J�tunheim, but travel there has been blocked to keep out Odin and Thor. M�mir, however, knows another passage. He instructs Kratos to cut off his head and have it revived by the Witch of the Woods, revealed to be Freya. Kratos immediately distrusts her, but both Freya and M�mir warn him that he must tell Atreus about his true nature.
