The path pided where the statue of King Daeron the First sat astride his tall stone horse, his sword lifted toward Dorne. A seagull was perched on the Young Dragon's head, and two more on the blade. Sam took the left fork, which ran beside the river. At the Weeping Dock, he watched two acolytes help an old man into a boat for the short voyage to the Bloody Isle. A young mother climbed in after him, a babe not much older than Gilly's squalling in her arms. Beneath the dock, some cook's boys waded in the shallows, gathering frogs. A stream of pink-cheeked novices hurried by him toward the septry. I should have come here when I was their age, Sam thought. If I had run off and taken a false name, I could have disappeared amongst the other novices. Father could have pretended that Dickon was his only son. I doubt he would even have troubled to search for me, unless I took a mule to ride. Then he would have hunted me down, but only for the mule.

Outside the Seneschal's Court, the rectors were locking an older novice into the stocks. "Stealing food from the kitchens," one explained to the acolytes who were waiting to pelt the captive with rotting vegetables. They all gave Sam curious looks as he strode past, his black cloak billowing behind him like a sail.

Beyond the doors he found a hall with a stone floor and high, arched windows. At the far end a man with a pinched face sat upon a raised dais, scratching in a ledger with a quill. Though the man was clad in a maester's robe, there was no chain about his neck. Sam cleared his throat. "Good morrow."

The man glanced up and did not appear to approve of what he saw. "You smell of novice."

"I hope to be one soon." Sam drew out the letters Jon Snow had given him. "I came from the Wall with Maester Aemon, but he died during the voyage. If I could speak with the Seneschal . . ."

"Your name?"

"Samwell. Samwell Tarly."

The man wrote the name in his ledger and waved his quill at a bench along the wall. "Sit. You'll be called when wanted."

Sam took a seat on the bench.

Others came and went. Some delivered messages and took their leave. Some spoke to the man on the dais and were sent through the door behind him and up a turnpike stair. Some joined Sam on the benches, waiting for their names to be called. A few of those who were summoned had come in after him, he was almost certain. After the fourth or fifth time that happened, he rose and crossed the room again. "How much longer will it be?"

"The Seneschal is an important man."

"I came all the way from the Wall."

"Then you will have no trouble going a bit farther." He waved his quill. "To that bench just there, beneath the window."

Sam returned to the bench. Another hour passed. Others entered, spoke to the man on the dais, waited a few moments, and were ushered onward. The gatekeeper did not so much as glance at Sam in all that time. The fog outside grew thinner as the day wore on, and pale sunlight slanted down through the windows. He found himself watching dust motes dance in the light. A yawn escaped him, then another. He picked at a broken blister on his palm, then leaned his head back and closed his eyes.

He must have drowsed. The next he knew, the man behind the dais was calling out a name. Sam came lurching to his feet, then sat back down again when he realized it was not his name.

"You need to slip Lorcas a penny, or you'll be waiting here three days," a voice beside him said. "What brings the Night's Watch to the Citadel?"

The speaker was a slim, slight, comely youth, clad in doeskin breeches and a snug green brigandine with iron studs. He had skin the color of a light brown ale and a cap of tight black curls that came to a widow's peak above his big black eyes. "The Lord Commander is restoring the abandoned castles," Sam explained. "We need more maesters, for the ravens . . . did you say, a penny?"

"A penny will serve. For a silver stag Lorcas will carry you up to the Seneschal on his back. He has been fifty years an acolyte. He hates novices, particularly novices of noble birth."

"How could you tell I was of noble birth?"

"The same way you can tell that I'm half Dornish." The statement was delivered with a smile, in a soft Dornish drawl.

Sam fumbled for a penny. "Are you a novice?"

"An acolyte. Alleras, by some called Sphinx."

The name gave Sam a jolt. "The sphinx is the riddle, not the riddler," he blurted. "Do you know what that means?"

"No. Is it a riddle?"

"I wish I knew. I'm Samwell Tarly. Sam."

"Well met. And what business does Samwell Tarly have with Archmaester Theobald?"

"Is he the Seneschal?" said Sam, confused. "Maester Aemon said his name was Norren."

"Not for the past two turns. There is a new one every year. They fill the office by lot from amongst the archmaesters, most of whom regard it as a thankless task that takes them away from their true work. This year the black stone was drawn by Archmaester Walgrave, but Walgrave's wits are prone to wander, so Theobald stepped up and said he'd serve his term. He's a gruff man, but a good one. Did you say Maester Aemon?"

"Aye."

"Aemon Targaryen?"

"Once. Most just called him Maester Aemon. He died during our voyage south. How is it that you know of him?"

"How not? He was more than just the oldest living maester. He was the oldest man in Westeros, and lived through more history than Archmaester Perestan has ever learned. He could have told us much and more about his father's reign, and his uncle's. How old was he, do you know?"

"One hundred and two."

"What was he doing at sea, at his age?"

Sam chewed on the question for a moment, wondering how much he ought to say. The sphinx is the riddle, not the riddler. Could Maester Aemon have meant this Sphinx? It seemed unlikely. "Lord Commander Snow sent him away to save his life," he began, hesitantly. He spoke awkwardly of King Stannis and Melisandre of Asshai, intending to stop at that, but one thing led to another and he found himself speaking of Mance Rayder and his wildlings, king's blood and dragons, and before he knew what was happening, all the rest came spilling out; the wights at the Fist of First Men, the Other on his dead horse, the murder of the Old Bear at Craster's Keep, Gilly and their flight, Whitetree and Small Paul, Coldhands and the ravens, Jon's becoming lord commander, the Blackbird, Dareon, Braavos, the dragons Xhondo saw in Qarth, the Cinnamon Wind and all that Maester Aemon whispered toward the end. He held back only the secrets that he was sworn to keep, about Bran Stark and his companions and the babes Jon Snow had swapped. "Daenerys is the only hope," he concluded. "Aemon said the Citadel must send her a maester at once, to bring her home to Westeros before it is too late."

Alleras listened intently. He blinked from time to time, but he never laughed and never interrupted. When Sam was done he touched him lightly on the forearm with a slim brown hand and said, "Save your penny, Sam. Theobald will not believe half of that, but there are those who might. Will you come with me?"

"Where?"

"To speak with an archmaester."

You must tell them, Sam, Maester Aemon had said. You must tell the archmaesters. "Very well." He could always return to the Seneschal on the morrow, with a penny in his hand. "How far do we have to go?"

"Not far. The Isle of Ravens."

They did not need a boat to reach the Isle of Ravens; a weathered wooden drawbridge linked it to the eastern bank. "The Ravenry is the oldest building at the Citadel," Alleras told him, as they crossed over the slow-flowing waters of the Honeywine. "In the Age of Heroes it was supposedly the stronghold of a pirate lord who sat here robbing ships as they came down the river."

Moss and creeping vines covered the walls, Sam saw, and ravens walked its battlements in place of archers. The drawbridge had not been raised in living memory.

It was cool and dim inside the castle walls. An ancient weirwood filled the yard, as it had since these stones had first been raised. The carved face on its trunk was grown over by the same purple moss that hung heavy from the tree's pale limbs. Half of the branches seemed dead, but elsewhere a few red leaves still rustled, and it was there the ravens liked to perch. The tree was full of them, and there were more in the arched windows overhead, all around the yard. The ground was speckled by their droppings. As they crossed the yard, one flapped overhead and he heard the others quorking to each other. "Archmaester Walgrave has his chambers in the west tower, below the white rookery," Alleras told him. "The white ravens and the black ones quarrel like Dornishmen and Marchers, so they keep them apart."

"Will Archmaester Walgrave understand what I am telling him?" wondered Sam. "You said his wits were prone to wander."

"He has good days and bad ones," said Alleras, "but it is not Walgrave you're going to see." He opened the door to the north tower and began to climb. Sam clambered up the steps behind him. There were flutterings and mutterings from above, and here and there an angry scream, as the ravens complained of being woken.

At the top of the steps, a pale blond youth about Sam's age sat outside a door of oak and iron, staring intently into a candle flame with his right eye. His left was hidden beneath a fall of ash blond hair. "What are you looking for?" Alleras asked him. "Your destiny? Your death?"

The blond youth turned from the candle, blinking. "Naked women," he said. "Who's this now?"

"Samwell. A new novice, come to see the Mage."

"The Citadel is not what it was," complained the blond. "They will take anything these days. Dusky dogs and Dornishmen, pig boys, cripples, cretins, and now a black-clad whale. And here I thought leviathans were grey." A half cape striped in green and gold draped one shoulder. He was very handsome, though his eyes were sly and his mouth cruel.

Sam knew him. "Leo Tyrell." Saying the name made him feel as if he were still a boy of seven, about to wet his smallclothes. "I am Sam, from Horn Hill. Lord Randyll Tarly's son."

"Truly?" Leo gave him another look. "I suppose you are. Your father told us all that you were dead. Or was it only that he wished you were?" He grinned. "Are you still a craven?"

"No," lied Sam. Jon had made it a command. "I went beyond the Wall and fought in battles. They call me Sam the Slayer." He did not know why he said it. The words just tumbled out.

Leo laughed, but before he could reply the door behind him opened. "Get in here, Slayer," growled the man in the doorway. "And you, Sphinx. Now."

"Sam," said Alleras, "this is Archmaester Marwyn."

Marwyn wore a chain of many metals around his bull's neck. Save for that, he looked more like a dockside thug than a maester. His head was too big for his body, and the way it thrust forward from his shoulders, together with that slab of jaw, made him look as if he were about to tear off someone's head. Though short and squat, he was heavy in the chest and shoulders, with a round, rock-hard ale belly straining at the laces of the leather jerkin he wore in place of robes. Bristly white hair sprouted from his ears and nostrils. His brow beetled, his nose had been broken more than once, and sourleaf had stained his teeth a mottled red. He had the biggest hands that Sam had ever seen.
