The moon was a crescent, thin and sharp as the blade of a knife. A pale sun rose and set and rose again. Red leaves whispered in the wind. Dark clouds filled the skies and turned to storms. Lightning flashed and thunder rumbled, and dead men with black hands and bright blue eyes shuffled round a cleft in the hillside but could not enter. Under the hill, the broken boy sat upon a weirwood throne, listening to whispers in the dark as ravens walked up and down his arms.

“You will never walk again,” the three-eyed crow had promised, “but you will fly.” Sometimes the sound of song would drift up from someplace far below. The children of the forest, Old Nan would have called the singers, but those who sing the song of earth was their own name for themselves, in the True Tongue that no human man could speak. The ravens could speak it, though. Their small black eyes were full of secrets, and they would caw at him and peck his skin when they heard the songs.

The moon was fat and full. Stars wheeled across a black sky. Rain fell and froze, and tree limbs snapped from the weight of the ice. Bran and Meera made up names for those who sang the song of earth: Ash and Leaf and Scales, Black Knife and Snowylocks and Coals. Their true names were too long for human tongues, said Leaf. Only she could speak the Common Tongue, so what the others thought of their new names Bran never learned.

After the bone-grinding cold of the lands beyond the Wall, the caves were blessedly warm, and when the chill crept out of the rock the singers would light fires to drive it off again. Down here there was no wind, no snow, no ice, no dead things reaching out to grab you, only dreams and rushlight and the kisses of the ravens. And the whisperer in darkness.

The last greenseer, the singers called him, but in Bran’s dreams he was still a three-eyed crow. When Meera Reed had asked him his true name, he made a ghastly sound that might have been a chuckle. “I wore many names when I was quick, but even I once had a mother, and the name she gave me at her breast was Brynden.”

“I have an uncle Brynden,” Bran said. “He’s my mother’s uncle, really. Brynden Blackfish, he’s called.”

“Your uncle may have been named for me. Some are, still. Not so many as before. Men forget. Only the trees remember.” His voice was so soft that Bran had to strain to hear.

“Most of him has gone into the tree,” explained the singer Meera called Leaf. “He has lived beyond his mortal span, and yet he lingers. For us, for you, for the realms of men. Only a little strength remains in his flesh. He has a thousand eyes and one, but there is much to watch. One day you will know.”

“What will I know?” Bran asked the Reeds afterward, when they came with torches burning brightly in their hand, to carry him back to a small chamber off the big cavern where the singers had made beds for them to sleep. “What do the trees remember?”

“The secrets of the old gods,” said Jojen Reed. Food and fire and rest had helped restore him after the ordeals of their journey, but he seemed sadder now, sullen, with a weary, haunted look about the eyes. “Truths the First Men knew, forgotten now in Winterfell … but not in the wet wild. We live closer to the green in our bogs and crannogs, and we remember. Earth and water, soil and stone, oaks and elms and willows, they were here before us all and will still remain when we are gone.”

“So will you,” said Meera. That made Bran sad. What if I don’t want to remain when you are gone? he almost asked, but he swallowed the words unspoken. He was almost a man grown, and he did not want Meera to think he was some weepy babe. “Maybe you could be greenseers too,” he said instead.

“No, Bran.” Now Meera sounded sad.

“It is given to a few to drink of that green fountain whilst still in mortal flesh, to hear the whisperings of the leaves and see as the trees see, as the gods see,” said Jojen. “Most are not so blessed. The gods gave me only greendreams. My task was to get you here. My part in this is done.”

The moon was a black hole in the sky. Wolves howled in the wood, sniffing through the snowdrifts after dead things. A murder of ravens erupted from the hillside, screaming their sharp cries, black wings beating above a white world. A red sun rose and set and rose again, painting the snows in shades of rose and pink. Under the hill, Jojen brooded, Meera fretted, and Hodor wandered through dark tunnels with a sword in his right hand and a torch in his left. Or was it Bran wandering?

No one must ever know.

The great cavern that opened on the abyss was as black as pitch, black as tar, blacker than the feathers of a crow. Light entered as a trespasser, unwanted and unwelcome, and soon was gone again; cookfires, candles, and rushes burned for a little while, then guttered out again, their brief lives at an end.

The singers made Bran a throne of his own, like the one Lord Brynden sat, white weirwood flecked with red, dead branches woven through living roots. They placed it in the great cavern by the abyss, where the black air echoed to the sound of running water far below. Of soft grey moss they made his seat. Once he had been lowered into place, they covered him with warm furs.

There he sat, listening to the hoarse whispers of his teacher. “Never fear the darkness, Bran.” The lord’s words were accompanied by a faint rustling of wood and leaf, a slight twisting of his head. “The strongest trees are rooted in the dark places of the earth. Darkness will be your cloak, your shield, your mother’s milk. Darkness will make you strong.”

The moon was a crescent, thin and sharp as the blade of a knife. Snowflakes drifted down soundlessly to cloak the soldier pines and sentinels in white. The drifts grew so deep that they covered the entrance to the caves, leaving a white wall that Summer had to dig through whenever he went outside to join his pack and hunt. Bran did not oft range with them in those days, but some nights he watched them from above.

Flying was even better than climbing.

Slipping into Summer’s skin had become as easy for him as slipping on a pair of breeches once had been, before his back was broken. Changing his own skin for a raven’s night-black feathers had been harder, but not as hard as he had feared, not with these ravens. “A wild stallion will buck and kick when a man tries to mount him, and try to bite the hand that slips the bit between his teeth,” Lord Brynden said, “but a horse that has known one rider will accept another. Young or old, these birds have all been ridden. Choose one now, and fly.”

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 suspe............
