The world is slowly dying, eaten away by an unseen force bent upon the utter destruction of Equestria. Celestia had pinned her hopes on a pony that was meant to save the world. Somewhere along the way everything went astray.

Far to the south Chrysalis amasses her armies for the final battle between pony and changeling. Through the aid of a negative energy crystal a new breed of changeling has arrived. The world shall burn before the might of the Undying Swarm. Death has come for Equestria on pellucid wings.

Prior knowledge of the "The Stormlight Archive" isn't needed.
