A.K. Yearling, known as Daring-Do in the world of explorers and adventurers, and her friend Leaf Wind are assigned a task by Princess Luna to travel to Saddle Arabia and search for an ancient and presumed destroyed library. What they discover beneath the shifting and sweltering sands may very well redefine the history of Equestria, it might even possibly define its future. One thing's for sure, though, Leaf and Daring's relationship will never be the same.
Takes place around the same time as Witching Hour's story "Steady as She Flies" as well as the end of Calm Wind's story "Flying Sky High"
