The moon was a crescent, thin and sharp as the blade of a knife. The days marched past, one after the other, each shorter than the one before. The nights grew longer. No sunlight ever reached the caves beneath the hill. No moonlight ever touched those stony halls. Even the stars were strangers there. Those things belonged to the world above, where time ran in its iron circles, day to night to day to night to day.

“It is time,” Lord Brynden said.

Something in his voice sent icy fingers running up Bran’s back. “Time for what?”

“For the next step. For you to go beyond skinchanging and learn what it means to be a greenseer.”

“The trees will teach him,” said Leaf. She beckoned, and another of the singers padded forward, the white-haired one that Meera had named Snowy locks. She had a weirwood bowl in her hands, carved with a dozen faces, like the ones the heart trees wore. Inside was a white paste, thick and heavy, with dark red veins running through it. “You must eat of this,” said Leaf. She handed Bran a wooden spoon.

The boy looked at the bowl uncertainly. “What is it?”

“A paste of weirwood seeds.”

Something about the look of it made Bran feel ill. The red veins were only weirwood sap, he supposed, but in the torchlight they looked remarkably like blood. He dipped the spoon into the paste, then hesitated. “Will this make me a greenseer?”

“Your blood makes you a greenseer,” said Lord Brynden. “This will help awaken your gifts and wed you to the trees.”

Bran did want to be married to a tree … but who else would wed a broken boy like him? A thousand eyes, a hundred skins, wisdom deep as the roots of ancient trees. A greenseer.

He ate.

It had a bitter taste, though not so bitter as acorn paste. The first spoonful was the hardest to get down. He almost retched it right back up. The second tasted better. The third was almost sweet. The rest he spooned up eagerly. Why had he thought that it was bitter? It tasted of honey, of new-fallen snow, of pepper and cinnamon and the last kiss his mother ever gave him. The empty bowl slipped from his fingers and clattered on the cavern floor. “I don’t feel any different. What happens next?”

Leaf touched his hand. “The trees will teach you. The trees remember.” He raised a hand, and the other singers began to move about the cavern, extinguishing the torches one by one. The darkness thickened and crept toward them.

“Close your eyes,” said the three-eyed crow. “Slip your skin, as you do when you join with Summer. But this time, go into the roots instead. Follow them up through the earth, to the trees upon the hill, and tell me what you see.”

Bran closed his eyes and slipped free of his skin. Into the roots, he thought. Into the weirwood. Become the tree. For an instant he could see the cavern in its black mantle, could hear the river rushing by below.

Then all at once he was back home again.

Lord Eddard Stark sat upon a rock beside the deep black pool in the gods wood, the pale roots of the heart tree twisting around him like an old man’s gnarled arms. The greatsword Ice lay across Lord Eddard’s lap, and he was cleaning the blade with an oilcloth.

“Winterfell,” Bran whispered.

His father looked up. “Who’s there?” he asked, turning … … and Bran, frightened, pulled away. His father and the black pool and the godswood faded and were gone and he was back in the cavern, the pale thick roots of his weirwood throne cradling his limbs as a mother does a child. A torch flared to life before him.

“Tell us what you saw.” From far away Leaf looked almost a girl, no older than Bran or one of his sisters, but close at hand she seemed far older. She claimed to have seen two hundred years.

Bran’s throat was very dry. He swallowed. “Winterfell. I was back in Winterfell. I saw my father. He’s not dead, he’s not, I saw him, he’s back at Winterfell, he’s still alive.”

“No,” said Leaf. “He is gone, boy. Do not seek to call him back from death.”

“I saw him.” Bran could feel rough wood pressing against one cheek. “He was cleaning Ice.”

“You saw what you wished to see. Your heart yearns for your father and your home, so that is what you saw.”

“A man must know how to look before he can hope to see,” said Lord Brynden. “Those were shadows of days past that you saw, Bran. You were looking through the eyes of the heart tree in your godswood. Time is different for a tree than for a man. Sun and soil and water, these are the things a weirwood understands, not days and years and centuries. For men, time is a river. We are trapped in its flow, hurtling from past to present, always in the same direction. The lives of trees are different. They root and grow and die in one place, and that river does not move them. The oak is the acorn, the acorn is the oak. And the weirwood … a thousand human years are a moment to a weirwood, and through such gates you and I may gaze into the past.”

“But,” said Bran, “he heard me.”

“He heard a whisper on the wind, a rustling amongst the leaves. You cannot speak to him, try as you might. I know. I have my own ghosts, Bran. A brother that I loved, a brother that I hated, a woman I desired. Through the trees, I see them still, but no word of mine has ever reached them. The past remains the past. We can learn from it, but we cannot change it.”

“Will I see my father again?”

“Once you have mastered your gifts, you may look where you will and see what the trees have seen, be it yesterday or last year or a thousand ages past. Men live their lives trapped in an eternal present, between the mists of memory and the sea of shadow that is all we know of the days to come. Certain moths live their whole lives in a day, yet to them that little span of time must seem as long as years and decades do to us. An oak may live three hundred years, a redwood tree three thousand. A weirwood will live forever if left undisturbed. To them seasons pass in the flutter of a moth’s wing, and past, present, and future are one. Nor will your sight be limited to your godswood. The singers carved eyes into their heart trees to awaken them, and those are the first eyes a new greenseer learns to use … but in time you will see well beyond the trees themselves.”

“When?” Bran wanted to know. “In a year, or three, or ten. That I have not glimpsed. It will come in time, I promise you. But I am tired now, and the trees are calling me. We will resume on the morrow.”

Hodor carried Bran back to his chamber, muttering “Hodor” in a low voice as Leaf went before them with a torch. He had hoped that Meera and Jojen would be there, so he could tell them what he had seen, but their snug alcove in the rock was cold and empty. Hodor eased Bran down onto his bed, covered him with furs, and made a fire for them. A thousand eyes, a hundred skins, wisdom deep as the roots of ancient trees.

Watching the flames, Bran decided he would stay awake till Meera came back. Jojen would be unhappy, he knew, but Meera would be glad for him, He did not remember closing his eyes.

… but then somehow he was back at Winterfell again, in the gods-wood looking down upon his father. Lord Eddard seemed much younger this time. His hair was brown, with no hint of grey in it, his head bowed. “… let them grow up close as brothers, with only love between them,” he prayed, “and let my lady wife find it in her heart to forgive …”

“Father.” Bran’s voice was a whisper in the wind, a rustle in the leaves. “Father, it’s me. It’s Bran. Brandon.”

Eddard Stark lifted his head and looked long at the weirwood, frowning, but he did not speak. He cannot see me, Bran realized, despairing. He wanted to reach out and touch him, but all that he could do was watch and listen. I am in the tree. I am inside the heart tree, looking out of its red eyes, but the weirwood cannot talk, so I can’t.
