When strange magic starts appearing in Canterlot, cousins Todd and Tex find themselves swept into a series of wild adventures alongside the Equestria Girls. From battling villains to navigating a world where magic and danger collide, the cousins quickly learn that Canterlot is anything but ordinary.

Equestria was once a land of unity, where earth ponies, unicorns, and pegasi lived side by side in harmony. Now, the tribes remain separated, their friendship reduced to little more than an old legend. But Shadow Plane is different. Haunted by visions of Equestria's past, and able to see the spirits of Twilight Sparkle's era, Shadow embarks on a journey with Sunny Starscout to restore the magic that was lost and bring the three tribes together once more. Because the legacy of friendship isn't over, it's waiting to be reborn.
