A strange and dangerous monster attacked Ponyville. Some ponies are wounded so Celestia decided to kill a monster. Witnesses said "It looks like a wolf. But not a normal wolf. This one is the biggest wolf that we've ever seen". Twillight, and her friends, went into a forest with task to kill the monster. During a travel they met a trop of wild wolves from a North. Their leader was a... pony called "Black Wolf- at your service".
