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.

Cancelled, but preserved for posterity.

Archer is not having a good day. He's recently been knocked unconscious and imprisoned by a Fae race, notorious for their animosity towards humans and each other. Instead of cannibalistic Merfolk or mischievous Fairies, he finds... talking ponies. Who want him to be their "friend."

He is sentenced to remain in a small town they call "Eqshana", until he can learn to "live in harmony" with its inhabitants. Unfortunately, a message from his king, Jove V, has turned his prison sentence into a mission of espionage. Now he must escape these no-doubt insidious creatures, and even more importantly, stay sane doing it. Along the way, he will answer one of the most important questions he has ever faced: Is there really nothing to eat around here besides hay?

Compelled by the unholy power of Aunts, young gentlecolt Birdy is sent to Canterlot to bolster Prince Blueblood's reputation and steal a piece of valuable military history.

With the help of his new (and impossibly intelligent) servant, he just might manage to survive the splendors of the capitol city.

Instead of being killed in the cold Antarctic by Dr. Manhattan, Rorschach finds himself rematerialized in a strange new, pony filled world. He finds himself drawn into the lives of the ponies of Ponyville but some ponies fear that this sociopath will bring danger and darkness to an otherwise peaceful existence. Will the mane 6 help Walter Kovac find peace within himself or will he bring them all down with him in his cold views of reality and existence?

War comes to Equestria: with despair, with starvation, with suffering and with sacrifice. And the ponies must learn how to keep true to their values while surviving not just the rigors of battle, but the desolation of total war.
