Twilight tries to find a important artifact for Luna and discovers a strange object unlike anything she has seen before. After accidentally activating it, Twilight and her friends find themselves in a new world, locked in seemingly eternal combat. Will they have what it takes to survive and adept to the new world, find the now missing Cutie Mark Crusaders and return home?

This fic is mainly a tribute to my friend http://www.youtube.com/user/Sakojima5555 and their videos, though the story is my original deign.

There exists an hour each day that goes inexperienced by everypony. An hour where both the Sun, and Moon are silent; Where dangerous living shadows thrive. Thankfully most ponies sleep through this "Midnight Hour", protected by a coffin, and blissfully unaware that such a time even exists. However when Twilight Sparkle receives an odd magical book, she finds herself experiencing this lost hour in time night after night. With no one to go to for fear of sounding crazy Twilight must unravel the secrets of the Midnight Hour, without putting her friends in harms way. But when seemingly healthy ponies start to fall prey to a mysterious illness which renders them completely unable to function like a normal pony with an invariable link to this strange new world. It's Twilight, and her friend who takes it upon themselves to save them.

The potion used to transform people into ponies has gone through many, many interations. When one of the older potions is used, results aren't quite what was expected.

EDIT: I used a piece of fanart which I thought was wonderful as the cover image :3
