No one is going to deny that they are very fortunate to live in the Equestria that they do. A land where tensions are low, the inhabitants are kind, and the environment tranquil. However, what if there existed other places, alternate timelines, where this wasn't the case? Worse still, what if such a place threatened to merge with the peaceful land that so many ponies came to know?

This is a question that Celestia poses to Twilight when a new, sudden danger threatens all of Equestria and beyond on an inter-dimensional level. Serving as Equestria's best hope for salvation, Twilight must cross dimensions into a drastically different world, one that will test her sanity, as well as her will to survive.

Little does she know, she will receive assistance from a very unexpected source: herself.

Borrows elements from the video game, Dark Souls, though not a crossover in and of itself.
