In the culmination of a storm, Alex White encounters Twilight Sparkle on his way home after a particularly disastrous week. When Twilight uncovers the truth, it shakes her to the very core. But her crossing the veil has alerted an ancient enemy from a hidden history; one that even the Elements were unable to defeat in ages past.

As one storm ends, another begins. With Twilight's faith tested and a daunting enemy lurking in shadows, she will need the Elements to overcome it all... but will it be enough?
