Music can be used for many things: bringing people together, bringing forth emotion, or even providing a window into a person's identity. However, could it be used to save Ponyville?

"Tell me something, if you can. What would you do if everypony you loved was suddenly taken away from you? Everypony that once provided you happiness and warmth and purpose, suddenly thrust from your grasp. Would you travel to the edge of the world for them? Beyond it? That's what I did. Because I needed to. Because there is nothing for me without them. Now you're going to tell me where they are, or I swear to the goddess I've lost that this will be twilight of my innocence."

When every last pony in Equestria save for Twilight inexplicably disappears overnight, a force from a parallel world is blamed. Now, the young mare plans to travel to this strange land in order to find what was lost to her, a world where a civilization of ponies thrives via the usage of not magic, but steam technology. With unexpected allies helping her from the shadows and light, Twilight will soon discover that things may not be as simple as they seem.

The world has mobilized for war, though this will not be a fight among themselves. Instead, every bow, talon, sword, gun, and magical spell is turning against an ancient threat from the Northern Continent, one which threatens to consume every living soul.

A draft is issued in Equestria to counter it, and the Mane Six and several other unexpected denizens of Ponyville are brought aboard the relative safety of Princess Luna's flagship, a massive airship called the Constellation, to fight for their nation. However, it may turn out that the word 'relative' should be strongly noted. Soon, they will learn just how close of bonds can form through the fires of war as well as well as the meaning of sacrifice.

Five years ago, Scotaloo's parents disappeared within the great jungles of Zebraca to the far south of Equestria. Many looked for them, but all returned empty handed. Years after giving up the hope of ever seeing them again, Scootaloo receives a mysterious package containing a journal belonging to her father.....

A month of being stranded in Ponyville has driven the Doctor to near madness. However, with the TARDIS finally fixed the last Time Lord is ready to begin exploring a new frontier. Of course, he won't be going without his trusty walking history book, Twilight. Brought back to the end of the War for the Sky where Nightmare Moon and Celestia clash, the Doctor and Twilight are set to uncover an old enemy's meddling with the time stream. However, mysterious third party may not be so happy about time being toyed with by either good or evil. An unflinching geekfest of a fanfic. I regret nothing.

As stars begin to disappear from the sky, a spacecraft of alien (non-human) origin slams into the Everfree Forest. The stage is set for Twilight and the rest of Equestria to uncover secrets their royalty has been hiding for thousands of years. Soon, they will take their place in a galaxy under siege.
