The CMCs are at it again. In an attempt to gain their cutie marks, our three protagonists discover an ancient tome in Twilight's library and use a spell promising to deliver them an "adventure beyond imagination." However, things do not go as planned, and the three young fillies find themselves awakening in a world far different from the beautiful land of Equestria. Now transformed and confused, the ponies must find each other and, hopefully, a way to return home. Yet when an evil arises that threatens not only this new world, but also their own home, will the CMC be able to protect those they care for most?
