Backstory: Originally a unicorn talented in magic and student of Princess Celestia's shortly after the banishment of Nightmare Moon. He was a dedicated pupil, determined to prove himself as worthy of her praise he pushed himself with trying to create more and more powerful spells. One night he finally developed what would become his Magnum Opus, a spell since lost to time, along with his identity and appearance before casting it. While performing the spell the intense magic proved too much for even him to withstand, causing his horn to shatter and his magic to attempt and fail an alicorn transformation.
He now resides in a hidden wing of Canterlot Castle, acting as a mysterious tutor to any student of Celestia's who are curious enough to stumble across him. This includes Twilight Sparkle whom he takes under his wing (well... metaphorically), seeing a lot of his younger self in her, however he fears that she may end up like him.
