Okay, so I went on deviantart and found some Diamond Tiara related art that I think is perfect for the story.

If Rosejule ever sees it used on my story and it turns out she doesn't want it used, please tell me and I will take it down and go back to the old screencap from "Crusaders of the Lost Mark".
