Unlike all the other disgusting alicorn OCs I've seen, mine, named Crystal Gleam, doesn't "have all the abilities" nor is she "immortal" like all the others.
She does have teleportation, levitation, and shield powers. She was not born an alicorn (like most would out of pure laziness), rather she worked her way to become one by being Princess Luna's student. She earned her cutie mark before she got her wings, by being skilled at finding buried gems without any tools. While she did become a princess herself, she declined wearing her official crown offered to her by Luna because she didn't want to be seen as spoiled or snobby. She does have her own castle, but rarely does anything there. She does keep a huge hoard of jewels in a super secure room guarded by her own royal guards. She is not Princess Luna, and she gets really pissed off when someone calls her Luna. Don't be a fool and piss off an alicorn princess.
