I'm Adagio Dazzle; a siren in a human from in the world of Equestria. I was sealed away in red gem on a black necklace where my soul now resides. If you or your friend friend puts this necklace on, the red gem will start to glow and they will begin to transform into me physically while I take full control of their minds. I will tempt my wearer and get them to fall for me and the idea of being me. If your friend becomes me, I'll reward you by allowing you to court me while I'm controlling them.
