The Soul Drinker

I titled this piece the "Soul Drinker" and it has a literature counterpart I am currently in the process of writing. Inspired by Dishonored and a little bit of Final Fantasy, it's about a girl from priviledged living who is seduced and taken away by a mysterious crow-clad boy, only to discover he is an infamous "Soul Drinker" who drinks his victims dry and is feared by entire civilizations. Opinions?
