Based on a true story. Kinda. Not really.
A man named Jason previously led a rather melancholy life before he died violently. No surprise there. But as he wakes up in Equestria and is thrown into a foreign body, he is forced to survive with the guise of a changeling. Taking place shortly after the failed changeling invasion of Canterlot, how can he keep from being revealed by new security measures, and blend into this new world, while making use of the most unlikely of allies? But of course, avoiding ponies only turns out to be the easy part when trouble has a habit of reading its ugly head. Really though, what could go wrong?

Props to the ever epic Zubafa for his cover art.

When a Necromancer is hurled into the place between places then escapes to another world at the cost of his life it is not the end. Being a Necromancer he returns to life with ease, but is skirting the edges of consciousness, and unable to truly wake as a mysterious figure uses magic to put him on the back of a horse to carry him away into the night.

To make matters worse the phylactery he used to save his own life recreated him as a member of the dominant race with... some errors. His injuries are still present and he's now in a much smaller body with his magic drained to nothingness.

So now he's horribly injured, held captive by an unknown force, in an unfamiliar body, in an unfamiliar world and completely exhausted. He's had worse days. He just can't think of any off the top of his head. So familiar territory then, nothing to worry about.

On Hiatus due to Life. Sorry.

After Rarity falls for a new prince, Spike is infuriated for wasting five years of his life trying to please her. So Twilight, being the good friend she is, decides to calm him down as much as she can. However, she may have been a little too nice to him, because later that night Spike begins to have romantic dreams about her. At first they horrify him, but eventually he begins to like them. Then he finally begins to understand why he keeps having these dreams; he's beginning to fall in love with his best friend, but will she return his affection or leave him out in the cold like Rarity?

On a warm summer day, Princess Celestia takes a walk around Ponyville, and meets a rather strange pony.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

"Dear Princess Celestia, as your (former) most faithful student, I feel I have to warn you that this is probably a trap. Chrysalis cannot possibly be serious about this. Why would anyone, much less her, want to shoot a documentary on us?"

Chrysalis, queen of all the changeling hives and infinitely cunning architect of their plans to conquer Equestria, has a problem: She knows diddly-squat about ponies. But Chrysalis is cleverer than most—or all—changelings, and she's already devised a brilliant solution to this trifling issue: Make a movie about them.
