Twilight has discovered a strange old book purportedly written by Star Swirl the Bearded, and Rainbow Dash discovers a latent spell in it that transports the two ponies to a strange island in the middle of nowhere. With no viable options available to them, Twilight and Rainbow begin to search the island for clues to a way home and the reason behind the odd puzzles and contraptions presented to them.

Dramatic Reading here.

At first glance, Princess Luna's charioteers might appear to be little more than Royal Guards dressed in festive apparel for Nightmare Night. However, there is far more to the story than that - the Night Guards once played a pivotal role in the history of Equestria, and have sacrificed more for their beloved princess than most ponies are even aware of.

Luna discovers something hidden from Celestia for twenty years, now, with emotions running high, she enlists the help of the Mane 6... but what seemed to be a single mystery, soon reveals a darker and much more complicated plot that will soon decide the fate of Equestria.
