A species of wolf from the ice age that grew much larger than gray wolves and lived in much larger packs. The last of them died out 10,000 years ago due to sudden climate change.
WTF... They didn't die bc of climate change... Joffrey had one killed... Rob's died the same night he did... Arya sent hers away... Bran and Rickon still have there's... Jon has his although it isn't seen very often.
Game of Throne references are coming.
