Nearly a century after six mares united under Equestria's greatest ideals, one is left to ponder her dreams, her life, and her legacy. In doing so, she may realize that friendship - much like magic - truly never dies.

When dark creatures begin appearing in Equestria, Princess Celestia and Princess Luna summon the bearers of the Elements of Harmony to Canterlot. Before the six ponies can arrive, though, four strange ponies are expelled from a portal that appears in the throne room, and they explain that Equestria is not the only place at risk from these creatures. Thus begins an adventure that will reveal a greater destiny for Ponyville's librarian than she could have ever dreamed of.
