On a quest to unravel an ancient mystery, one which ties all ponies of Equestria together, Sunny Starscout and her friends make an awe-inspiring discovery...
After everyone thinks they're a couple, Pipp and Hitch realize their feelings for each other and start dating. Meanwhile Zipp, Sunny and Izzy also search for love. Unknown to them, Opaline continues her attempts to take all magic for herself.
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.
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.
In a world where magic and ponies are a distant memory, a changeling and a kirin go on a journey to find out where they went. (A New Generation species swap AU.)
(Spoilers for Make Your Mark: Chapter 4.) While still adjusting to life in Maretime Bay, Misty happens to bump into Sprout. As it turns out, Sprout knows something about what Misty's going through. In fact, he's had a similar experience.
(Based on a fan comic.) Sprout runs away from Maretime Bay and makes an unusual "friend". Said friend convinces Sprout to turn on his other friends. When things look bleak for Sunny and the gang, some unexpected faces show up to help.
