Thanks to Twilight and her friends; Midnight Star was given a second chance at life. A chance to be happy without the horrors of her memories; but those memories where never truly gone. With their return, Midnight finds herself torn between harmony and chaos. But her struggles are only beginning; a greater threat has emerged. The Frozen Empire.

With Celestia and Luna beyond reach while investigating the silence of Saddle Arabia, and Twilight injured, it is up to Midnight to act in Twilight's name in order to defend Equestria. The only question is; can she do what must be done to stop the Frozen Empire and still keep her darker side at bay? Or will she destroy the very land she's trying to protect?
