Fluttershy finds an interesting item in the woods: a mask. Such a simple thing. And yet, it causes quite a bit of a stir in Ponyville.

When one of Fluttershy's dear animal companions wanders into the Everfree, she sets out to bring him home safely - but what she finds at the center of the forest is something she didn't expect, and something that ushers in a change to her world that makes each day darker than the last.
