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.

Rainbow Dash's morning was pretty much ruined.
She tripped getting out of bed and landed flat on her face, giving herself an aching muzzle.
She forgot to buy her favorite brand of hay flakes at the store yesterday and had to eat plain toast for breakfast.
She found out she had to pull double-duty today and tomorrow on the weather patrol.
Oh, and she found a nearly-dead foal, broken and bleeding at the edge of Ponyville.

The rest of her day became a whirlpool of stress and worry but the colt woke up, thank Celestia.
Something's not right, though. Nopony can find his parents, he's not in the registers, and there's an unsettling look in his eye...

3/14/24 Still Alive Edition

There's only one pony in Ponyville that the Mane Six have never met. Pinkie Pie has never thrown him a party, Applejack has never sold him a mug of cider, and Twilight has never seen him check out any books. And as far as that unicorn, Lapis Print, is concerned, that's exactly how it should be.

Lapis can't risk them knowing where he lives, what he does for a living, or even what his name is - if he gets his way, the Mane Six won't even know he exists, and nopony in Ponyville will miss him once he's gone.

It should be a piece of cake - after all, it's not like the biggest magical power in Equestria is about making sure everypony looks out for each other, right?
