Robb whistled. They heard the faint sound of soft feet on wet leaves.
The undergrowth parted, low-hanging branches giving up their accumulation of snow, and Grey Wind and Summer emerged from the green. Summer sniffed the air and growled.
Wolves, gasped Hali.
Direwolves, Bran said. Still half-grown, they were as large as any wolf he had ever seen, but the differences were easy to spot, if you knew what to look for.
Maester Luwin and Farlen the kennelmaster had taught him.
A direwolf had a bigger head and longer legs in proportion to its body, and its snout and jaw were markedly leaner and more pronounced.
There was something gaunt and terrible about them as they stood there amid the gently falling snow. Fresh blood spotted Grey Wind's muzzle.
Dogs, the big bald man said contemptuously. Yet I'm told there's nothing like a wolfskin cloak to warm a man by night. He made a sharp gesture. Take them.
Robb shouted, Winterfell! and kicked his horse. The gelding plunged down the bank as the ragged men closed.
A man with an axe rushed in, shouting and heedless. Robb's sword caught him full in the face with a sickening crunch and a spray of bright blood.
The man with the gaunt stubbly face made a grab for the reins, and for half a second he had them...and then Grey Wind was on him, bearing him down.
He fell back into the stream with a splash and a shout, flailing wildly with his knife as his head went under.
The direwolf plunged in after him, and the white water turned red where they had vanished.
《权力的游戏》是一部中世纪史诗奇幻题材的电视连续剧。该剧以美国作家乔治·R·R·马丁的奇幻巨作《冰与火之歌》七部曲为基础改编创作，由大卫·贝尼奥夫和丹尼尔·威斯编剧、HBO电视网推出。乔治·雷蒙德·理查德·马丁是欧美奇幻小说大师。马丁的作品主要以人物为关注点，描写细腻丰富，突破了幻想文学界固有的创作模式，多次引领阅读潮流。由于马丁的辉煌成就，他被誉为美国的托尔金和新世纪的海明威。从1989年开始，马丁淡出文学界，转而投身演艺界发展，1996年他才重返文坛而开始奇幻文学的创作，处女作便是《权力的游戏》，即为《冰与火之歌》的首部曲。《权力的游戏》甫出便拿下了British Fantasy Society、 世界奇幻奖和星云奖年度最佳幻想作品提名，在非官方的不记名奇幻作品投票中，《冰与火之歌》俨然已经可以和《魔戒》平起平坐，作者网站的访问量也是和斯蒂芬·金、J.K.罗琳等不相上下，其受欢迎的程度可见一斑。乔治马丁被时代杂志评选为2011年影响世界的一百人之一。
