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.

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...
