Sequel to Magic in the Stars...I would advise reading that first before venturing here.

For nearly four months, a young pegasus stallion has been living a life many have dreamed of, but he alone has experienced. Starfall has been at Canterlot, undertaking advanced astronomy studies under the Guardian of the Night, Princess Luna herself. But in these four months, both pegasus and alicorn have been hiding a secret from the world of Equestria...a relationship that delves much deeper than that of student and mentor.

With this relationship keeping Starfall in near-constant proximity to the Lunar Princess, he has been training under the Royal Guard, learning the skills needed to defend himself, and the Princesses, should the need ever arise. But Starfall is struggling in his training, while Luna is dealing with her own personal issues in the wake of the return of the mysterious, ancient Crystal Empire.

The couple decide to take a trip to the mysterious city in the middle of Equestria's desolate Frozen North, Starfall to see if Shining Armor can provide a new insight to his training, Luna to search for answers Canterlot and Ponyville have both failed to provide. Both wish to also treat it like a holiday, and perhaps take some time to indulge in simple, romantic pleasures that have been sorely lacking in their secretive lives so far.

But as they get settled in to the Crystal Empire, demons from both Starfall and Luna's past rear their heads. With their shared world spiraling out of control, and dark forced looming on the horizon, can their secret relationship possibly remain hidden? Can it even survive the coming storm? Can Equestria itself survive? Starfall's courage and very life have been pushed to the limit once already. This time, it might not be enough...

Companion One-Shot to "Magic in the Stars". If you do not want to be spoiled regarding that story, avoid this until you read up to Chapter 20, "Common Ground", of "Magic in the Stars.

Late one night, Twilight Sparkle is up late, as she often does, writing a letter. But tonight is unusual in that this letter is not to her mentor, Princess Celestia. But as she struggles to find the best way to convey what she wants to say in her letter, she is interrupted by her assistant, Spike, who inadvertently makes an accusation that may be closer to home than Twilight ever considered...

Starfall is a pegasus with a past he would rather forget, and a future that does not appear to even exist. His only true talent is a gift and passion for the stars and the night sky, a passion he has cultivated since he was a small colt. So when he learns of a chance to make this hobby a lifetime career, he travels all the way to Canterlot, desperate to make something of himself.

But during this opportunity, Starfall talent for reading the stars draws the attention of several ponies, including Equestria's royalty, and the alicorn who created the night sky he is so fond of; Princess Luna. What had started as a chance for a better life turns into an opportunity he could never have imagined, as the Princess of the Night begrudgingly takes him under her wing, teaching him all there is to know about the night.

But as Starfall adjusts to this new world he has been thrown into, complications rapidly begin to arise. Can the young, introverted pegasus learn to cope with the fame his new position will thrust upon him? Can anypony break through his defences, and bring out the pegasus he was always meant to be? And can he keep a secret from the Princess of the Night herself, as his feelings threaten to run away from him?
