Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Shaken from watching her friends succumb to Discord's tricks and Chrysalis' deception not long ago, Twilight Sparkle decides that the Elements of Harmony should be more than ready for the next threat, whatever that threat may be. When her eagerness to be prepared yields a grave mistake with consequences reaching farther than the Elements can imagine, all Tartarus breaks loose. It will take finding the truth of the Elements to have any hope in fixing their transgressions, and their friendships. From the littlest filly to the Heavenly Goddesses themselves, everypony's way of life hinges on a group of mares who may not have it all together.

Lyra is a young mare returning to the capital for business instead of pleasure after a falling out with her closest friend. Pressured by all those who love and care for her, she's on a journey of self discovery and ascension. Assigned the task of becoming truly independent and learning how to make her way in the world, the only thing standing in her way is herself. That, and the world falling apart around her.

To man this post, Princess Twilight Sparkle, Temporary Governor of Arstrotzka, has assigned a small time East Manetin labor worker as the customs inspector of the checkpoint. It seems like a boring job, a simple paper pusher in a city torn by nationalism. However, as the inspector will soon find out, his job will be anything but uninteresting, as he gets involved in something many times bigger than verifying documents. And it all begins with a simple sentence.
