He was an outcast of a previous society. His family, friends, and everything he knew was...gone. And everypony blamed him for it. He was kicked out, and abandoned. Before he left, he left one last surprise as a thing of revenge. Before he knew it, they were all dead.

He then arrived in Equestria, more specifically, Ponyville. He wanted to make a new life. It seemed everypony cared, but one stood out to him. This one, beautiful, mare. Her name of course, was Twilight Sparkle.

Meanwhile, the Templar are moving toward Equestria, and a big war is about to happen. Tranquilius must reveal his identity before it is too late, but will Twilight accept him for who he actually is, a professional killer?

Beyond Earth and beyond the Universe within which Earth exists there is a place full of love; the richest mine of love that can be found, as it is seen by those capable of utilizing it...

Within that place, specifically a part of it called the Everfree Forest, awakes one such creature: a Changeling; specifically, a Changeling who had been a human on Earth the day before. How will he survive in a body that literally needs love for nourishment, while in a world that is now wise to the Changelings' tricks and has branded them evil? Better question: Will he be able to change more than his physical appearance?

These questions are not the only thing that will plague him, for the hows and whys of his arrival and transformation are in a hurry to reveal themselves, and Equestria's heart will stop as it waits for its fate to be decided.

Now with a side story (with more to come) from other characters' POV!
