You come to my little Entrancement Shoppe and you are a massive, just a real behemoth of a man. I gawk and marvel at you, but you confess that you've always wanted to be smaller, more normal sized and beg for my help. I decide to use a transfer spell on you and soon I have you in a trance as I weaken and shrink you and take all of your size for myself, so you shrink down and I grow bigger and stronger in the process, Until you're nothing but a little plaything to me.
