After a tragic accident, a human ends up in Lord Tirek's body, as part of an attempt to reform the villain after his recent escapades. While the hero of our tale is trying to make sense of his new surroundings, the rest of Equestria thinks that the most terrible threat that their world has ever seen is back...
And the powers that be are definitely not happy about it.

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Applebloom just wanted to spend a day with her friends, crusading for her cutie mark. Instead, she found something even deeper and more troubling about herself. Turns out she's not even a member of the Apple Family by blood. In fact, she's not even truly native to Equestria! She's an alien! An alien robot no less!

Now Applebloom will have to deal with the reality of her origins and try to cope with them and her newfound abilities as she moves towards her future; a future that just might never come to be if her new foes have anything to say about it. Decepticons are, after all, a monstrous cabal.

Now, it's up to Applebloom to light Equestria's darkest hour.
