Avengers (Loki)

Intro you are a sorcerer/sorceress. You got taken over by a dark entity who took his place inside of you, you became evil, but thankfully, Loki managed to get you out of it. You and Loki are best friends and are almost never seperated, Thor may or may not be jealous of this. You don't talk about your past, and everyone knows it and doesn't question it because they know you have been through some tough shit. You are now an Avenger but, the evil entity that took over you left his scar, veins on your left side of your neck are black you also have a cut on your cheek, both of those things you never let anyone touch them, infact you barely touch them yourself.
