The storm is breaking on the Horizon.

It's been two months since the battle against Nightmare Moon. Luna is recovering, Celestia is busy turning the government back into a diarchy, and the Mane Six have returned to their lives. All seems well, but when Celestia discovers that half of the power of the Elements of Harmony have been transferred to each of the Bearers, she decides to send thirteen mysterious members of the Royal Guard to monitor them as they manifest and develop their new abilities.

The sins of a forgotten war still linger, and an ancient evil lurks in the shadows, just waiting for the right time to strike. The Mane Six suddenly find themselves once again at the heart of a conspiracy to bring about Eternal Night, and only by awakening their powers and realizing their full potential can they do anything to stop it. Friends both old and new will help them along the way, and an unseen force will guide them as it seeks to right a wrong made thousands of years ago. The Bearer's journeys will take them outside the borders of Equestria and into the world beyond, and when they return, they'll have the power and experience necessary to save the world and bring about balance in all things.

Twilight told her friends of her adventures in the Human world, but she didn't tell them everything. One dark secret haunts her still.

Hamburgers are delicious.

Fluttershy gets possessed by a demon. Antics ensue.

For more than a millennium, it was believed that the princesses were immortal. But as time marched ever forward, it become clear that even the alicorns won't live forever.

Princess Celestia is at the end of her life.

While Equestria must find a way to cope with this new reality, those that are truly suffering are those closest to her. None are struggling as much as her sister, Princess Luna. Not only is she forced to handle the duties of ruling Equestria and taking care of the transition, she must also cope with the imminent death of her beloved sister.

"You cannot die unless your patron does."
The answer to the first question Twilight asked when she formally became the princess of magic. Billions of years later, she regrets not thinking this through.

Princess Celestia has called Twilight Sparkle and her friend Rainbow Dash to meet her in at the castle. Unsure of why they are the only ones called to there they make haste for Canterlot.

Only one way to find out.
