Cloudy Day has a history of being forced to change schools after bizarre accidents start occuring around her. Her most recent transfer has landed her at Canterlot High, where she hopes she'll be able to settle down and finish out her highschool years without anything strange happening.

Sun Chaser is a social outcast and an oddity amongst the student body of Canterlot High. He spends most of his time living out of his family's workshop in the local scrap-yard just outside of town. Due to personal reasons he's been absent from school for the past few months, but he's scheduled to return soon.

Between these two students, the recently renewed attendance of the Dazzlings, and the new friendships with the students at Crystal Prep Academey, it seems Sunset and her friends have their work cut out for them.

Using the defeat of Dicord to cover their tracks, a host of evil creatures sneak into Equestria. A lone outsider, a guardian against dimensional aggressors, is ambushed and trapped inside a ponified body. Now, suffering from mild amnesia, he must travel across Equestria to defeat the evil he is charged with protecting this dimension from whilst also searching for a way to free him from his cursed form.
