To a boy, Winterfell was a grey stone labyrinth of walls and towers and courtyards and tunnels spreading out in all directions. In the older parts of the castle, the halls slanted up and down so that you couldn't even be sure what floor you were on. The place had grown over the centuries like some monstrous stone tree, Maester Luwin told him once, and its branches were gnarled and thick and twisted, its roots sunk deep into the earth.
When he got out from under it and scrambled up near the sky, Bran could see all of Winterfell in a glance. He liked the way it looked, spread out beneath him, only birds wheeling over his head while all the life of the castle went on below. Bran could perch for hours among the shapeless, rain-worn gargoyles that brooded over the First Keep, watching it all: the men drilling with wood and steel in the yard, the cooks tending their vegetables in the glass garden, restless dogs running back and forth in the kennels, the silence of the godswood, the girls gossiping beside the washing well. It made him feel like he was lord of the castle, in a way even Robb would never know.
It taught him Winterfell's secrets too. The builders had not even leveled the earth; there were hills and valleys behind the walls of Winterfell. There was a covered bridge that went from the fourth floor of the bell tower across to the second floor of the rookery. Bran knew about that. And he knew you could get inside the inner wall by the south gate, climb three floors and run all the way around Winterfell through a narrow tunnel in the stone, and then come out on ground level at the north gate, with a hundred feet of wall looming over you. Even Maester Luwin didn't know that, Bran was convinced.
His mother was terrified that one day Bran would slip off a wall and kill himself. He told her that he wouldn't, but she never believed him. Once she made him promise that he would stay on the ground. He had managed to keep that promise for almost a fortnight, miserable every day, until one night he had gone out the window of his bedroom when his brothers were fast asleep.
He confessed his crime the next day in a fit of guilt. Lord Eddard ordered him to the godswood to cleanse himself. Guards were posted to see that Bran remained there alone all night to reflect on his disobedience. The next morning Bran was nowhere to be seen. They finally found him fast asleep in the upper branches of the tallest sentinel in the grove.
As angry as he was, his father could not help but laugh. "You're not my son," he told Bran when they fetched him down, "you're a squirrel. So be it. If you must climb, then climb, but try not to let your mother see you."
Bran did his best, although he did not think he ever really fooled her. Since his father would not forbid it, she turned to others. Old Nan told him a story about a bad little boy who climbed too high and was struck down by lightning, and how afterward the crows came to peck out his eyes. Bran was not impressed. There were crows' nests atop the broken tower, where no one ever went but him, and sometimes he filled his pockets with corn before he climbed up there and the crows ate it right out of his hand. None of them had ever shown the slightest bit of interest in pecking out his eyes.
Later, Maester Luwin built a little pottery boy and dressed him in Bran's clothes and flung him off the wall into the yard below, to demonstrate what would happen to Bran if he fell. That had been fun, but afterward Bran just looked at the maester and said, "I'm not made of clay. And anyhow, I never fall."
Then for a while the guards would chase him whenever they saw him on the roofs, and try to haul him down. That was the best time of all. It was like playing a game with his brothers, except that Bran always won. None of the guards could climb half so well as Bran, not even Jory. Most of the time they never saw him anyway. People never looked up. That was another thing he liked about climbing; it was almost like being invisible.
He liked how it felt too, pulling himself up a wall stone by stone, fingers and toes digging hard into the small crevices between. He always took off his boots and went barefoot when he climbed; it made him feel as if he had four hands instead of two. He liked the deep, sweet ache it left in the muscles afterward. He liked the way the air tasted way up high, sweet and cold as a winter peach. He liked the birds: the crows in the broken tower, the tiny little sparrows that nested in cracks between the stones, the ancient owl that slept in the dusty loft above the old armory. Bran knew them all.
Most of all, he liked going places that no one else could go, and seeing the grey sprawl of Winterfell in a way that no one else ever saw it. It made the whole castle Bran's secret place.
His favorite haunt was the broken tower. Once it had been a watchtower, the tallest in Winterfell. A long time ago, a hundred years before even his father had been born, a lightning strike had set it afire. The top third of the structure had collapsed inward, and the tower had never been rebuilt. Sometimes his father sent ratters into the base of the tower, to clean out the nests they always found among the jumble of fallen stones and charred and rotten beams. But no one ever got up to the jagged top of the structure now except for Bran and the crows.
He knew two ways to get there. You could climb straight up the side of the tower itself, but the stones were loose, the mortar that held them together long gone to ash, and Bran never liked to put his full weight on them.
The best way was to start from the godswood, shinny up the tall sentinel, and cross over the armory and the guards hall, leaping roof to roof, barefoot so the guards wouldn't hear you overhead. That brought you up to the blind side of the First Keep, the oldest part of the castle, a squat round fortress that was taller than it looked. Only rats and spiders lived there now but the old stones still made for good climbing. You could go straight up to where the gargoyles leaned out blindly over empty space, and swing from gargoyle to gargoyle, hand over hand, around to the north side. From there, if you really stretched, you could reach out and pull yourself over to the broken tower where it leaned close. The last part was the scramble up the blackened stones to the eyrie, no more than ten feet, and then the crows would come round to see if you'd brought any corn.
