Skaði (also referred to as Skadi, Skade, or Skathi) is a Jötunn and Norse goddess associated with bowhunting, skiing, winter, and mountains. In all sources, she is depicted as being the wife of the Vanir-God. However, in Heimskringla, Skaði is described as having split up with Njörðr and has later married , and that the two produced many children together. In both the Poetic Edda and the Prose Edda, Skaði is responsible for placing the serpent that drips venom onto the bound .
Skadi's shape shifting father was responsible for kidnapping the goddess Idunn and stealing the golden apples from her garden. When the gods heard of this Odin demanded the gods to go kill Thiazzi and to bring Idunn and the golden apples back to Valhalla. The giant eagle was hunted down and killed. When Skadi found out that her father was dead she grieved for a long time.
The gods decided to have a celebration for the safe return of Idunn and the death of Thiazzi. However the feast stopped when Skaði came bursting through the doors of Valhalla with a cold winter air the female Jöhar came seeking vengeance for the death of her father.
Seeing the rage in Skaði Odin and the other gods acted out of fear they lied saying the celebration was to honor Skaði and her father Thiazzi. Odin then placed Thiazzi among the stars but Skaði still believed Odin was lying. During the feast Loki was able to make Skaði laugh her grudge against the gods of Valhalla went away.
Skaði married Njörðr during the Idunn's celebrated safe return to Valhalla however their marriage wouldn't last because Skaði couldn't live in the sea and Njörðr couldn't live in the icy cold. Before her marriage to Njörðr and after her marriage to him. Odin has tried many times to get Skaði to love but failed.
Although Skaði placed the venom dripping serpent over Loki as he is bound and chained. Skaði was now the goddess of winter after her marriage to Njörðr. She tried to warn Loki about the punishment that Odin and the gods had for him as Ragnarök started getting closer.

Before God of War (2018)
Skaði learned how to hunt from her father, Thiazi, a shapeshifter. She became a huntress beyond compare, even to any god. Even the jötnar Guardian, Laufey, admires her.
Odin wanted her for his bride, believing she would bear him strong sons. Skaði spurred his affections, and for that insult, Odin vowed revenge. It was put forth that the Aesir was plagued by an Eagle who would steal the precious golden apples of Iðunn. Not even the finest archers among the gods could bring it down.
Odin knew Skaði could not resist the temptation to prove herself superior. Skaði hunted down the Eagle and shot it with a bow. When she went to collect her quarry, she found no Eagle but her own father slain. Skaði was overcome with grief and shame and succumbed to her fate as winter came, holding her father in an eternal embrace.
