Giant

Giants are a legendary race of enormous, fierce humanoids, standing ten to thirteen feet tall, covered in hair and teeth, with wives who have beards like their husbands, making it difficult to tell the sexes apart. They are said to have giant's blood, and some half-bloods are born from unions between human women and giant men, though the men are so large they often rip a maid apart before getting her with child. The wildling woman Osha, who was born and raised beyond the Wall, claims to have seen giants and even states that her brother killed one—a stunted female ten feet tall. She dismisses the maester's claim that giants are all dead, insisting that if Maester Luwin rode beyond the Wall, he would find giants, or they would find him. The giants are part of the old races that fled north when the Andals came, and they are said to still live in the deep woods and frozen wastes beyond the Wall, alongside the children of the forest and other ancient beings. In the stories Old Nan tells, the wildlings are said to consort with giants, and the giants are often mentioned in the same breath as ghouls and the Others, adding to the terror they inspire. The giants are also referenced in the context of the Wall's construction, as the great structure is said to have been built by Brandon the Builder with the help of giants, though this is a legend from the Age of Heroes. The giants are also mentioned in the context of the Dothraki sea, where it is said that ghost grass, taller than a man on horseback, will cover the entire world and all life will end, a prophecy that echoes the fear of the giants' eventual return. The giants are a symbol of the wild, untamed north, a reminder of a time when the world was more savage and less civilized, and their presence in the stories and legends serves to underscore the danger and mystery of the lands beyond the Wall.
