In the clearing of an unnamed forest between Canterlot and Ponyville, the bodies of Rainbow Dash and Pinkie Pie were found, along with the wreckage of a flying machine. The Royal Guard are claiming it was a tragic accident, but Twilight Sparkle suspects that there is more to it. Will she find an answer to a question that nopony asked, or is she just trying to distract herself from her own grief?

Celestia has been keeping a close eye on her once wayward sister Luna, but that hasn't stopped Luna from plotting her demise (and the demise of the Elements of Harmony) in absolute secrecy. After three-years under house arrest in the castle, the first steps in her plan to overthrow Princess Celestia have been set in motion, on the night of a full moon, as she schemes to take the throne and bring the lands of Equestria to everlasting night once again, and killing all who stand in her way.
