The students of Twilight's School of Friendship are cramming for "History of Magic in Equestria" exam in the school library when they discover a part of the school that no pony else knows about. When they decide to do some exploring they end up learning much more than they bargained for.
"Get your muzzle out of those books and make some friends!" That's what Princess Celestia tells Twilight Sparkle. She may be the smartest unicorn in Equestria, but Twilight Sparkle gets an "incomplete" in friendship. There's more to life than learning magic, after all - so she goes to Ponyville on a mission to make friends. There she meets five special ponies who take her on exciting adventures and teach her the most powerful magic of all... the magic of friendship!
