Warg

Wargs, also known as Dire wolves, are a species of highly dangerous magical beasts that originate from ancient Nordic lands, but are now an epidemic worldwide. They are descended from the wolves Sköll and Hati, sons of the wolf Fenrir, son of the Nordic Immortal Loki and his ogress wife Angrboda.

Appearance
Wargs basically look like mundane wolves, however, there are a few things that separate themselves from mundane wolves. They have fur as black as night, eyes as red as blood, fangs bared at anything other than other wargs, and, most astonishing of all, they are wolves the size of horses.

Behavior
Wargs are wolves that are much more dangerous than mundane wolves. They are so dangerous, the only ones allowed to even go near them are Loki's demigod children, as only they have the ability to communicate with these wild beasts. The only other ones allowed near these beasts are other wargs, and/or mundane wolves.
