The old gods
The old gods are the ancient, nameless deities of the forest, stream, and stone, whose worship predates the arrival of the Andals in Westeros. They are the gods of the children of the forest and the First Men, and in the north, particularly at Winterfell, their presence is still deeply felt. Unlike the Faith of the Seven, which has a structured hierarchy, holy texts, and named gods, the old gods have no priests, no temples, and no sacred writings. Their only shrines are the weirwood trees, pale-barked sentinels with deep-cut eyes and red leaves, into which the children of the forest carved faces to keep watch over the woods. These trees are the heart of any godswood, and it is before them that oaths are sworn and prayers are offered.
Nature and Worship
The old gods are described as nameless and faceless, a stark contrast to the seven-faced god of the southron faith. Catelyn Stark, a Tully by birth who worships the Seven, finds the Winterfell godswood a dark, primal place, a three-acre forest untouched for ten thousand years, where the gods have no names. The heart tree, a great weirwood with a carved face, broods over a black pool, its red eyes seeming to follow her. Ned Stark, who keeps the old gods, seeks the quiet of the godswood after taking a man's life, cleaning the greatsword Ice in the black waters. The Starks' words, "Winter is coming," are a touchstone of this faith, a reminder of the harsh, unforgiving nature of the world and the gods who rule it. The blood of the First Men still flows in the veins of the Starks, and they hold to the belief that the man who passes the sentence should swing the sword, a tradition rooted in their ancient faith.
The Weirwood as Sacred Space
The weirwood tree is the central sacred object of the old gods. Its bark is white as bone, its leaves dark red, like a thousand bloodstained hands. The face carved into the trunk is long and melancholy, with deep-cut eyes red with dried sap, and is said to be older than Winterfell itself. These trees are not merely symbols; they are believed to see and remember. In the south, the last weirwoods were cut down or burned out a thousand years ago, except on the Isle of Faces, where the green men keep their silent watch. In the north, every castle has its godswood, and every godswood has its heart tree, and every heart tree its face. This physical presence of the divine is a constant, watchful force. When Bran Stark, in his coma, has a vision, he sees the great white weirwood at the heart of the godswood brooding over its reflection in the black pool, and when it feels him watching, it lifts its eyes from the still waters and stares back at him knowingly.
The Old Gods and the Night's Watch
The old gods are also the gods of the Night's Watch. Castle Black has no godswood, but beyond the Wall, the haunted forest stands as it stood in the Dawn Age, and there is a grove of weirwoods where brothers of the Watch can say their vows. Jon Snow, a Stark bastard, chooses to swear his oath before a heart tree, as his uncle Benjen did before him. Samwell Tarly, though born to the Faith of the Seven, chooses to forsake the gods of his father and swear his vows to the old gods, saying, "The Seven have never answered my prayers. Perhaps the old gods will." This choice underscores the old gods' association with a more ancient, personal, and less forgiving form of faith, one that is tied to the harsh realities of the Wall and the lands beyond.
Contrast with the Faith of the Seven
The old gods stand in direct opposition to the Faith of the Seven, the dominant religion of the south. The Faith of the Seven has a complex hierarchy, with a High Septon, septons, and septas, and its worship involves rituals, songs, and the smell of incense. Its gods have names and faces, and its worship is a public, communal affair. The old gods, by contrast, are nameless and faceless, and their worship is a solitary, personal matter, conducted in the silent, brooding presence of a weirwood. This religious divide is a source of cultural tension, marking the north as a distinct and separate realm from the south. The Starks, who keep the old gods, are seen as strange and somewhat primitive by the southron lords, while the northerners view the southron faith as foreign and soft. The old gods are a faith of the deep woods, of winter, and of a harsh, unforgiving world, a world where the only time a man can be brave is when he is afraid.
