Everypony is the hero of their own story. That's how the old saying goes. But Deft Embrace is no hero. Terrified of stepping outside the walls of Neighgaton, and with telekinesis so weak she can barely fire a small pistol, she doesn't have the makings of a hero.

But Deft is a mother, and when danger threatens her two young fillies she will find that the line between mother and hero is sometimes blurred. And that even a weak, frightened mare can be a fierce fighter when defending her children.

But will it be enough? What can one mare do against the whole wasteland?

Equestria awakes one morning to discover a massive storm has formed over Cloudsdale, one which even experienced weather ponies have no control over. Rainbow Dash, with help from her friends, must investigate this strange storm and find a solution before the problem spreads all over Equestria. Meanwhile, the Cutie Mark Crusaders are having some adventures of their own.

After being banished by the Elements of Harmony, Nightmare Moon returns. She tracks down Luna, and the princess of the night must face her greatest nightmare alone.
