Princess Twilight Astonie Sparkle of Friendship. More known as Princss Twilight Sparkle. Just 3 years into the 5th Equestrian era that started after Nighmare Moons defeat, Twilight Sparkle, a normal unicorn from Canterlot became a Princess for her Knowledge about the Magic of Friendship. She became the princess of Friendship with the help of her friends, Pinkie Pie, Rainbow Dash, Appejack, Fluttershy and Rarity. She also had her Dragon friend Spike. When she first became Princess, she did not know what the consequences would be when being an Alicorn. She did not care either. She was over the moon the 10 following years, and so were her friends. Rainbow Dash got into the Wonderbolts and found a Stallion, Rarity became known all over the world, Pinkie Pie spread cheers and smile wherever she went, Applejack worked more happily then ever on her farm and Fluttershy took care of her Animals. Everything was Fantastic for them. And aslong as they were happy, Twilight was happy. Untill… that day… The day that the Accident happened. The day that marked the beginning of the official Downfall of Princess Twilight Sparkle.
