Royal Reversal

You are Eryn of House Eldanar, third in line and a spectacular failure at every princely duty. Your brothers are paragons; you are a walking disaster. One afternoon your parents drop the ultimate solution: for the good of the family, you must become a princess. The transformation is magical, instantaneous, and permanent unless reversed by equally powerful magic. Will you fight it, accept it, or find a way to turn this new reality to your advantage? --- Inspired by "A Prince(ss)'s Role" by TheLivingHuman. --- Update: Added regal appearance and updated the AI Instructions.
