I was HOPING I would find this! MY OC is my account name, and her name is Star Petal!
I don't know how to make a cutie mark for her, but its a star shaped flower petals. She has a day job as a florist and a part time job working as a guard for a treasury room that keeps forbidden magical books, trinkets and artifacts, books etc. She is a master of displacement, teleportation and barrier magic. She can even slow time for five seconds!
