A newborn foal is found in the streets of Canterlot. Nobody knows who he is, or how he got there, only that he already has a cutie mark. However, several mysteries, surround the foal as it grows under Celestia. Mysteries that start to come to light when Nightmare Moon arrives. With the help of his friends and family, Beacon will work to discover what is happening to him....

And what he really is.....

(After the first two chapters, this will take place in an episode by episode format, starting with “Mare In the Moon.” I do not own any of the MLP franchise.)

Canterlot is in turmoil. Ponies are split between supporters of the new Princess Twilight Sparkle, or her enemies. Now constantly surrounded by three of her brother's best guards due to other Solar and Lunar guards who had gotten close to Twilight being picked off by assassins. Twilight begins to doubt how long she has left until an attempt on her life is foiled by a strange intelligent creature that was discovered after a comet struck the castle. What is this creature, where did it come from, and is this some plot by her enemies to end her life?

Chaos reigns over Canterlot as a mysterious unicorn named Dark Secrets arrives to assist the beleaguered Cadence and Shining Armor, who have their hooves full running two empires, searching for Celestia, and trying to deal with the growing shadow spawn attacks. In Ponyville, Twilight has fallen into a depression at the loss of her mentor Celestia, and will not talk to anypony except for Spike and her friends. While time goes on, and Lucid Dream gains strength, an awakened Princess Luna reveals to these ponies a shocking secret, one that asks the question: Is Lucid Dream really the enemy here?

For over a thousand years have we slept, enduring the dying screams of my brothers and sisters in arms. For over a thousand years have we dreamed of the day when we would break free of these bonds that bind us to our prison and come back into the world. For we were there when the nightmare had been banished... We were there when the Nightguard fell and was imprisoned. We were imprisoned because we followed her and yet we helped the sun. But we did not think that the sun would banish the nightmare or send us to endure more hardships. This is why we never forgot, and never forgave. Now, it seems that we will finally break free of this place, as Twilight Sparkle will be the key to releasing us both, entity and unicorn, to take our revenge on the sun!
