Wolves.

At one time, the world was filled with them, long before Equestria was formed. Terrifying and misunderstood, though deadly all the same, they ruled the woodlands of old. That was- until they disappeared.

Now, they are nothing but legendary, mythical creatures, only talked about in whispers around a crackling campfire, or on a dark and stormy night. Though these tales are just fiction, right? These creatures never existed…

But that's the thing about ghost stories. Sometimes, a title can have more meaning than one is used to.

Now, Twilight Sparkle and her friends will discover secrets long forgotten, as her and her friends, save for Rainbow Dash, literally become legends of claws and teeth. Loyalty will be tested, as will the notion of what's truly 'natural', and what it takes to survive.

And the only two princesses who can help them have fallen asleep on the job.
