Words at Play : The Real History Behind 10 Game of Thrones Words
You might be familiar with wargs from The Lord of the Rings books, where the word warg referred to an evil breed of wolf. But a warg on Game of Thrones takes on an entirely different form.
Maybe even quite literally.
A warg is an individual who is able to enter the mind of an animal or even another human being to control their movement, and to see things they would otherwise be unable to see.
Tolkien, a great medievalist, coined the word warg, which is an English adaptation of the Old Norse word vargr, which means "wolf."
