Y/N is Thor and Lokis older sister. However they are very protective of her even though she has fenrih by her side. About five years ago Y/N begged Odin to let her live on earth among the mortals. She gave up being next in line and her father told her brothers that she had died on a mission as I said I’d never return to Asgard. What she didn’t plan on is meeting Peter who is her age now twenty three.
