He chose one bird, and then another, without success, but the third raven looked at him with shrewd black eyes, tilted its head, and gave a quork, and quick as that he was not a boy looking at a raven but a raven looking at a boy. The song of the river suddenly grew louder, the torches burned a little brighter than before, and the air was full of strange smells. When he tried to speak it came out in a scream, and his first flight ended when he crashed into a wall and ended back inside his own broken body. The raven was unhurt. It flew to him and landed on his arm, and Bran stroked its feathers and slipped inside of it again. Before long he was flying around the cavern, weaving through the long stone teeth that hung down from the ceiling, even flapping out over the abyss and swooping down into its cold black depths. Then he realized he was not alone. "Someone else was in the raven,"

he told Lord Brynden, once he had returned to his own skin. "Some girl. I felt her."

"A woman, of those who sing the song of earth," his teacher said.

"Long dead, yet a part of her remains, just as a part of you would remain in Summer if your boy's flesh were to die upon the morrow. A shadow on the soul. She will not harm you."

"Do all the birds have singers in them?"

"All," Lord Brynden said. "It was the singers who taught the First Men to send messages by raven ... but in those days, the birds would speak the words. The trees remember, but men forget, and so now they write the messages on parchment and tie them round the feet of birds who have never shared their skin."

Old Nan had told him the same story once, Bran remembered, but when he asked Robb if it was true, his brother laughed and asked him if he believed in grumkins too. He wished Robb were with them now. I' d tell him I could fly, but he wouldn' t believe, so I' d have to show him. I bet that he could learn to fly too, him and Arya and Sansa, even baby Rickon and Jon Snow. We could all be ravens and live in Maester Luwin' s rookery. That was just another silly dream, though. Some days Bran wondered if all of this wasn't just some dream. Maybe he had fallen asleep out in the snows and dreamed himself a safe, warm place. You have to wake, he would tell himself, you have to wake right now, or you' ll go dreaming into death. Once or twice he pinched his arm with his fingers, really hard, but the only thing that did was make his arm hurt. In the beginning he had tried to count the days by making note of when he woke and slept, but down here sleeping and waking had a way of melting into one another. Dreams became lessons, lessons became dreams, things happened all at once or not at all. Had he done that or only dreamed it?

"Only one man in a thousand is born a skinchanger," Lord Brynden said one day, after Bran had learned to fly, "and only one skinchanger in a thousand can be a greenseer."

"I thought the greenseers were the wizards of the children," Bran said. "The singers, I mean."

"In a sense. Those you call the children of the forest have eyes as golden as the sun, but once in a great while one is born amongst them with eyes as red as blood, or green as the moss on a tree in the heart of the forest. By these signs do the gods mark those they have chosen to receive the gift. The chosen ones are not robust, and their quick years upon the earth are few, for every song must have its balance. But once inside the wood they linger long indeed. A thousand eyes, a hundred skins, wisdom deep as the roots of ancient trees. Greenseers. "

Bran did not understand, so he asked the Reeds. "Do you like to read books, Bran?" Jojen asked him.

"Some books. I like the fighting stories. My sister Sansa likes the kissing stories, but those are stupid."

"A reader lives a thousand lives before he dies," said Jojen. "The man who never reads lives only one. The singers of the forest had no books. No ink, no parchment, no written language. Instead they had the trees, and the weirwoods above all. When they died, they went into the wood, into leaf and limb and root, and the trees remembered. All their songs and spells, their histories and prayers, everything they knew about this world. Maesters will tell you that the weirwoods are sacred to the old gods. The singers believe they are the old gods. When singers die they become part of that godhood."

Bran's eyes widened. "They're going to kill me?"

"No," Meera said. "Jojen, you're scaring him."

"He is not the one who needs to be afraid."

The moon was fat and full. Summer prowled through the silent woods, a long grey shadow that grew more gaunt with every hunt, for living game could not be found. The ward upon the cave mouth still held; the dead men could not enter. The snows had buried most of them again, but they were still there, hidden, frozen, waiting. Other dead things came to join them, things that had once been men and women, even children. Dead ravens sat on bare brown branches, wings crusted with ice. A snow bear crashed through the brush, huge and skeletal, half its head sloughed away to reveal the skull beneath. Summer and his pack fell upon it and tore it into pieces. Afterward they gorged, though the meat was rotted and half-frozen, and moved even as they ate it.

Under the hill they still had food to eat. A hundred kinds of mushrooms grew down here. Blind white fish swam in the black river, but they tasted just as good as fish with eyes once you cooked them up. They had cheese and milk from the goats that shared the caves with the singers, even some oats and barleycorn and dried fruit laid by during the long summer. And almost every day they ate blood stew, thickened with barley and onions and chunks of meat. Jojen thought it might be squirrel meat, and Meera said that it was rat. Bran did not care. It was meat and it was good. The stewing made it tender.

The caves were timeless, vast, silent. They were home to more than three score living singers and the bones of thousands dead, and extended far below the hollow hill. "Men should not go wandering in this place," Leaf warned them. "The river you hear is swift and black, and flows down and down to a sunless sea. And there are passages that go even deeper, bottomless pits and sudden shafts, forgotten ways that lead to the very center of the earth. Even my people have not explored them all, and we have lived here for a thousand thousand of your man-years."

Though the men of the Seven Kingdoms might call them the children of the forest, Leaf and her people were far from childlike. Little wise men of the forest would have been closer. They were small compared to men, as a wolf is smaller than a direwolf. That does not mean it is a pup. They had nut-brown skin, dappled like a deer's with paler spots, and large ears that could hear things that no man could hear. Their eyes were big too, great golden cat's eyes that could see down passages where a boy's eyes saw only blackness. Their hands had only three fingers and a thumb, with sharp black claws instead of nails.

And they did sing. They sang in True Tongue, so Bran could not understand the words, but their voices were as pure as winter air. "Where are the rest of you?" Bran asked Leaf, once.

"Gone down into the earth," she answered. "Into the stones, into the trees. Before the First Men came all this land that you call Westeros was home to us, yet even in those days we were few. The gods gave us long lives but not great numbers, lest we overrun the world as deer will overrun a wood where there are no wolves to hunt them. That was in the dawn of days, when our sun was rising. Now it sinks, and this is our long dwindling. The giants are almost gone as well, they who were our bane and our brothers. The great lions of the western hills have been slain, the unicorns are all but gone, the mammoths down to a few hundred. The direwolves will outlast us all, but their time will come as well. In the world that men have made, there is no room for them, or us."

She seemed sad when she said it, and that made Bran sad as well. It was only later that he thought, Men would not be sad. Men would be wroth. Men would hate and swear a bloody vengeance. The singers sing sad songs, where men would fight and kill.

One day Meera and Jojen decided to go see the river, despite Leaf's cautions. "I want to come too," Bran said.

Meera gave him a mournful look. The river was six hundred feet below, down steep slopes and twisty passages, she explained, and the last part required climbing down a rope. "Hodor could never make the climb with you on his back. I'm sorry, Bran."

Bran remembered a time when no one could climb as good as him, not even Robb or Jon. Part of him wanted to shout at them for leaving him, and another part wanted to cry. He was almost a man grown, though, so he said nothing. But after they were gone, he slipped inside Hodor's skin and followed them.

The big stableboy no longer fought him as he had the first time, back in the lake tower during the storm. Like a dog who has had all the fight whipped out of him, Hodor would curl up and hide whenever Bran reached out for him. His hiding place was somewhere deep within him, a pit where not even Bran could touch him. No one wants to hurt you, Hodor, he said silently, to the child-man whose flesh he'd taken. I just want to be strong again for a while. I' ll give it back, the way I always do. No one ever knew when he was wearing Hodor's skin. Bran only had to smile, do as he was told, and mutter "Hodor" from time to time, and he could follow Meera and Jojen, grinning happily, without anyone suspecting it was really him. He often tagged along, whether he was wanted or not. In the end, the Reeds were glad he came. Jojen made it down the rope easily enough, but after Meera caught a blind white fish with her frog spear and it was time to climb back up, his arms began to tremble and he could not make it to the top, so they had to tie the rope around him and let Hodor haul him up. "Hodor,"

he grunted every time he gave a pull. "Hodor, hodor, hodor."

The moon was a crescent, thin and sharp as the blade of a knife. Summer dug up a severed arm, black and covered with hoarfrost, its fingers opening and closing as it pulled itself across the frozen snow. There was still enough meat on it to fill his empty belly, and after that was done he cracked the arm bones for the marrow. Only then did the arm remember it was dead. Bran ate with Summer and his pack, as a wolf. As a raven he flew with the murder, circling the hill at sunset, watching for foes, feeling the icy touch of the air. As Hodor he explored the caves. He found chambers full of bones, shafts that plunged deep into the earth, a place where the skeletons of gigantic bats hung upside down from the ceiling. He even crossed the slender stone bridge that arched over the abyss and discovered more passages and chambers on the far side. One was full of singers, enthroned like Brynden in nests of weirwood roots that wove under and through and around their bodies. Most of them looked dead to him, but as he crossed in front of them their eyes would open and follow the light of his torch, and one of them opened and closed a wrinkled mouth as if he were trying to speak. "Hodor," Bran said to him, and he felt the real Hodor stir down in his pit.

Seated on his throne of roots in the great cavern, half-corpse and half-tree, Lord Brynden seemed less a man than some ghastly statue made of twisted wood, old bone, and rotted wool. The only thing that looked alive in the pale ruin that was his face was his one red eye, burning like the last coal in a dead fire, surrounded by twisted roots and tatters of leathery white skin hanging off a yellowed skull.

The sight of him still frightened Bran - the weirwood roots snaking in and out of his withered flesh, the mushrooms sprouting from his cheeks, the white wooden worm that grew from the socket where one eye had been. He liked it better when the torches were put out. In the dark he could pretend that it was the three-eyed crow who whispered to him and not some grisly talking corpse.
