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.

Nearly a century after six mares united under Equestria's greatest ideals, one is left to ponder her dreams, her life, and her legacy. In doing so, she may realize that friendship - much like magic - truly never dies.

Derpy dreams about the time she met Dinky's father, the love of her life.

When Applejack and Big Macintosh come across a badly beaten colt on their property, they take him in. But can they handle the physical, mental and emotional scars on the surface and deep in their guest's soul. And why is he insist they are in danger?

Rated TEEN mainly for events later in the story. Characters will be added as the story unfolds.

A human child is found at the edge of the Everfree forest. She seems to embody all the innocence and magic that make up Equestria and the fantastical creatures that live there, but as the six friends struggle to care for her and find a way to get her home they discover that the human world can be a cruel and tragic place and through this loss of innocence they realize that they are what hopes and dreams mean to a child in another world who has no hope left.

Twilight Sparkle has read about about what she believes may be an ancient library deep within the Everfree Forest called Ravenspire and, friends in tow, she heads out to find it. However what she finds inside this place is a creature, ancient beyond reckoning, desperately clinging to memories of a time long past when the kingdoms of Chaos ruled and all paid homage to the Ruinous Powers.

Added the human tag for way later. Like around the end, for like a thousand words.

Down voted by Commander Ponysun, so you know it's good!
