Welcome to Equestria, a world of friendship and magic! Twilight Sparkle has been crowned Princess of the Crystal Empire, and now she wants to learn how to be a good leader. Inspired by her friend Princess Cadance, Twilight sets off on a quest to discover the Crystal Heart Spell - a magical spell that will help her follow her heart no matter what.

Princess Cadance tries to bring the Crystal Empire together with a garden celebration to herald the arrival of spring. But when the plants have an unusual effect on the ponies, will she and her pony friends fix everything and bring happiness back to the kingdom? Love is in the air – or at least it should be on Hearts and Hooves Day! But when an outbreak of the pony sniffles turns this loving holiday into a disaster, Princess Cadance must find a way to get every pony through the winter blues. And what better way than a Garden Hearts Celebration?

All the ponies in Equestria love the Summer Sun Celebration – all except Princess Luna. So when she discovers a surprise Winter Moon Festival is planned just for her, Luna is determined to stop the party! Princess Luna, the guardian of the night, peacefully rules over Equestria alongside her big sister. When the Cutie Mark Crusaders suggest she should have a holiday as equally prestigious as Celestia's Summer Sun Celebration, she declines. Luna isn't comfortable with such attention – especially after all the terror she caused as Nightmare Moon.

While attempting to find a way to stop a curse that's affecting all the books in Ponyville, Princess Twilight Sparkle discovers a lost and forgotten village that just might hold the key. Princess Twilight Sparkle is so close to finishing her Autumnal Equine-nox spell, she can feel it. But she needs one more book to pull it off, and it’s extraordinarily rare. As the leaves in Ponyville start to fall, her search for the text takes her to the town of Bales. It’s packed with libraries and bookshops, so the princess is in a reader’s paradise!

Princess Celestia travels to a distant land to help an old friend bring the magic back to her homeland. When any pony asks Princess Celestia for help, she is more than happy to be of service. So when Duchess Diamond Waves says she is in desperate need of assistance, the wise leader of Equestria clears her schedule. Arriving at Monacolt Magic Academy, Celestia notices that her dear old friend seems to have lost her sparkle.
