Labyrinth

Cali is a goddess, who was "murdered" by Odin. only to find herself abandoned on Midgard and adopted by the starks; she thought maybe she could change her prophecy by becoming a superhero. Only to be betrayed by the very same superheroes who once welcomed her with open arms.

(The timeline is very off from the story. please just go with it. as far as this story is concerned, there is no Thanos. Civil war happened, but everyone is happy and living life as superheroes. Loki knows he is a frost giant, so there won't be any freaking out because he is a frost giant. we all know and love him for it. )
