"An Age of Darkness will come when the lessons of Harmony are forgotten. When Equestria reaches this darkest hour, the Protectors of Equestria will return to lead the way back to Harmony." -- The Final Prophecy of Princess Flurry Heart
After a team of pegasi return cursed with frost that cannot be thawed, Sunny and her friends must confront a far older threat that looms in the frozen North.
When Zipp chases down Sunny to a lonely coastline with a new lead from the ancient past, she finds herself pursued by a more recent history that keeps her stuck in the present.
Sunny and Hitch learn that a dragon named Spike was responsible for sending Sparky's egg to Maretime Bay. They and their friends then seek out Spike to try to get some answers about what happened to Equestria and Princess Twilight.
It was just supposed to be a short flight. Take some selfies, livestream a few videos of smiling unicorns, and voila! Thousands of hooftaps. But real life sometimes doesn't work that way.
Just after all the fuss of magic being back is sorted, Sunny returns home to the reminder that she has no home. This is not something her friends will let stand.
After Misty flees the sleepover, Zipp notices she's still in the garden outside the Crystal Brighthouse. Zipp ends up learning something unexpected about the strange newcomer -- and how she can help.
Izzy Moonbow has always felt alone. Until one day, when she comes across a garden hidden amongst the trees and its caretaker, a strange mare named Luna.
The ponies of Maretime Bay don't know the lone Sea Pony who lives near their shoreline. She knows them, though. If only she could find a way up there...
Sunny is careful to use her new abilities and influence only to help others. But even so, she notices everypony in town is increasingly tense and fearful around her. And then she finds out why...
