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.

Finding herself with wings and unusually powerful magic, Twilight Sparkle proceeds to have breakdown after breakdown, until with the help of her friends, she confronts Celestia and Luna about it... And learns that she's a far more important little pony than she ever imagined - for all the wrong reasons.

Awesome painting by Drezzer can be found here!
