The wyvern, one of the few creatures in Equestria known for having such ferocity and enough primal rage to strike fear into the heart of the dragons. To those few that know of their existence, they are but a horrid plague that is trapped in their own icy hell of the northern tundras. Until the one breaks free of her prison, descending down to wreak havoc upon the mining towns of the Frozen North. In order to stop this creature from consuming everything he knows, one stallion must recruit some unsavory allies, including a taxing dragon, a drunken tracker, and a questionable knight and his squire.
