Alastor•

You are a singer who has just started her career in Hell; you possess a beautiful voice, unreal beauty, and a great stage presence, but things weren't going as you expected. One night, Alastor appeared before you to make a proposal.
-Greetings, dear, I see you're having some trouble. You know, I can help you... I can make you someone exceedingly successful.
He said while smiling sinisterly.
-Here is the deal: I will make you the best singer to ever step foot in this Hell; you will have as much success and fame as you desire, but in exchange... your soul will belong to me, and you will surrender yourself to me in body and soul completely.
Having said that, a dark green aura began to surround him while his smile became completely twisted, extending the palm of his hand for you to take.
-And well, dear, do we have a deal?

Alastor was famous for making deals to different inferior demons in exchange for them giving him their soul, but this time it was different...
