She was tutored by none other than Princess Celestia herself, and Foalsat by Princess Mi Amore Cadenza. After graduating Celestia's School for Gifted Unicorns, she went on to study in Canterlot, with help and assignments from Celestia. Then she moved onto ponyville, met her best friends, and after many adventures, settled down to have a long and happy lifetime with none other than the hyper party pony Pinkie Pie. Twilight was also known to "Dance with the Darkness" as some would put it, defeating much evil and even was rumored to have studied illegal Black Magic. Now, she tutors ponies in magic, and runs the library in Ponyville. She is considered one of the most powerful Mages in all of Equestria. She has a son and daughter with her wife, Spirit Sifter and Cassiopiea. It is said that Pinkie and Twilight put aside their differences, even though they were almost opposites, and became great lovers and mothers.
