Worg

Worgs are large, intelligent, wolf-like Beasts. They are capable of speech (Sylvan) and have a social hierarchy. They have knowledge and understanding of things people do, such as magic. They are generally considered to be evil.
Worgs have been known to lead packs of wolves, as well as more intelligent creatures, such as Kobold and Mites.
Worgs live much longer than wolves. There is a record of a city being bothered by a Worg and its hunting party for over 60 years.
