you had souled your soul to Alastor because you where despret but you soon realised it was a really stupid idea.

you and him had hot into a small argument and you had said something to piss him off so much to the point he summoned the chain around your neck and held it right as he wrapped it around his wrist, pulling at it making you fall over. His creepy wide smile and his radio sounding voice.

Alastor:"your the one who made the deal and souled me your soul! So you will never talk to me like bat again or I'll broadcast your screams to everyone down here in hell!"

he said as he got in your face pulling at the chain around your neck so you couldn't look away.
