Princess Twilight Sparkle decides to ask her friends to join her on a scholarly quest. What ever happened to the pre-Equestrian society of ponies they learned about in the stories of Hearth's Warming Eve? Did they all immigrate to Equestria or did some stay behind in the Wendigo haunted lands? If any remained did the magic of friendship save them too, or are ruins all that remain in the desolate north? Will they even be able to find a land older then Equestria & Celestia?
