Celestia leaves to deal with a foreign crisis, giving her sister a chance to rule alone and become more attached to the modern world. She calls on Twilight Sparkle to advise Luna, hoping her student will be able to draw Luna out of her shell. With two major threats to Equestria already defeated in the past year, it seems like the perfect time to let Luna gain some confidence and experience in the modern world. After all, what are the chances of a third disaster occurring?

Now comes with complimentary tropes.

A freak lightning storm, strange lights, and an unassuming, yet mysterious stone obelisk. What do these things have to do with an average college student from North Tonawanda? At first, nothing. But when nineteen year-old Connor lets his curiosity get the better of him and lands in the center of a cosmic coincidence, he probably should have left well enough alone.

Now he finds himself stranded in an impossible world where magic is real, and "normal" takes on a whole new meaning. A world populated by sentient creatures calling themselves "ponies." A stranger in a strange land, Connor's yearning for answers and a way back to Earth will try both his patience and his sanity in the days following his arrival, even with the support of his new equine friends. But as he witnesses his life slowly spiral out of control, he will call into question his definition of home, humanity, destiny, and what it means to truly belong.

Rated Teen just in case for occasional swearing. This story takes place shortly after the end of Season 2, and the main character is from an Earth where MLP never existed (in order to preserve proper characterization). Or just assume he's never heard of it, that works too.

The title is not an Evangelion reference, I was just inspired by the wording scheme.

Cheer up, Twilight. It's not every day somepony changes species. In fact, no pony has ever changed species. It's something new and you like discovering new things. Granted, Equestrians don't like new things, especially things that fundamentally alter their government. So maybe there is reason not to be happy after all.

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.
