This is Amy and I'm sorry if your OC is also named Amy I don't have a name for her but the name Amy came into my head and I named her that and I'm sorry if it copies your OC's name T^T.

She's a princess that followed every rule to be a queen but somebody took it so she found a necklace in an ancient red box and found the necklace and that is why she has that black cracked thing on her in her after form it has gone missing since the necklace does have a soul of it's own.
