Something has happened and Twilight finds herself in a strange and dark new world. The Bipeds here have strange magic, advanced technology, and a lot of problems. She needs a few friends, and they just might need her. WORM crossover. Deadpan29 has created some great supplementary material that is canon to the story.

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.

What if instead of a chest, The tree of harmony gave Twilight a book with strange writing and a heart shaped gem on the cover. After reading a mysterious rhyme: "When the time is right. Underneath the same light. A bond will ignite. At very first sight." The Mane Six, and Spike, are all magically sucked in and they travel to a world with no ponies or magic, but humans and...bending! People who can control the four elements of nature. With no way to get back home, they stumble upon a new friend: Avatar Korra, a fiery but big hearted young girl with an extraordinary destiny. Upon first glance, the Ponies all feel an instant connection with the young girl, who might also be the key to them returning to Equestria and uncovering the secrets of the book, while at the same time help Korra to defeat an evil masked man named Amon who vows to rid the world of bending with his mysterious and terrifying powers.

Now the ponies will need to adjust to their new environment: a whole new world where people seem to loose sight of friendship almost too easily, but Twilight sees that there is hope, as they show Korra the ways of Equestria and with that, the ponies and avatar start to change their world for the better, by helping everyone see that Friendship is exactly the kind of magic that this world truly needs.
