Long ago, the War of the Magi reduced the World of Harmony to a scorched wasteland, and the powerful Magic of old ceased to exist. Even unicorns, the sole remaining wielders of conscious magic, were left with naught but the weakest of telekinetic power.

1000 years have passed... metals, focusing gems, explosives, and steam engines have been rediscovered, and high technology reigns. But once again there are those ponies who seek to enslave the World of Harmony by reviving the dreaded destructive power of Magic. Even now, Harmony hangs by a thread.

Can it be that those in power are on the verge of repeating a senseless and deadly mistake?

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.

In the last five years humanity has been brought to its knees by the conversion movement and the purification that has followed. Now in its final hour the last survivors of this once great race will make their last stand. Set in the Conversion bureau: Ten Rounds universe.

It's funny how a random whim can turn out to cause the most profound encounters in a person's life. By attempting a bit of magic, I was able to get the once in a lifetime chance to talk with actual royalty! Only, royalty from another world...

Harry Potter was a lonely boy who one day wished for a friend. Luna, trapped on the moon, wished for the same. And so their wishes are granted. How will the two deal with each other? And what about Nightmare Moon? Needless to say, their lives are going to change in both expected and unexpected ways...

Chapters 9-11 now re-written.

A minor accident at Sweet Apple Acres sends Big Macintosh to Ponyville in the middle of applebuck season. At first, things seem fine. But then some of the mares begin acting a little...oddly.

Then very oddly. Turns out every other stallion skipped town for a very good reason.

Not everypony who crawls out of a stable can be a Littlepip or a Blackjack. Some try and fail. Some just give up after a while. Some are still alive fifteen years after they emerged, admittedly, crippled or insane, but hey, this is the wasteland. Cyborgs Anne and her brain damaged mother Lee are forced to return to the hell hole that created them in order to find out what was done to them almost two decades ago, and that means putting down their tools and picking up their guns again.
