Black Direwolf

Black Direwolf (黒牙狼族) is an evolution from a regular Direwolf. If they evolved in a more magic-oriented fashion, their fur would turn black.

In volcanic regions, direwolves would evolve with a fire element and become red direwolves. Near bodies of water, you would find blue direwolves. In the forests would be green direwolves. In other words, adopting elements was a fairly common evolutionary pattern for Direwolves.

These wolves were apparently a notorious threat to any nearby humans and humanoids.
