Published: Feb '18
A thief breaks into Canterlot Castle to steal Celestia's crown while Twilight is visiting. It's a nice little character piece. Both the thief and Celestia's super crown are a little underdeveloped due to the short runtime, but Twilight isn't. It's pretty rare to see the "wise alicorn" angle explored with her so it's always a delight when a fic taps into it.
