“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.

When Sam hesitated, one of those hands grabbed him by the arm and yanked him through the door. The room beyond was large and round. Books and scrolls were everywhere, strewn across the tables and stacked up on the floor in piles four feet high. Faded tapestries and ragged maps covered the stone walls. A fire was burning in the hearth, beneath a copper kettle. Whatever was inside of it smelled burned. Aside from that, the only light came from a tall black candle in the center of the room.

The candle was unpleasantly bright. There was something queer about it. The flame did not flicker, even when Archmaester Marwyn closed the door so hard that papers blew off a nearby table. The light did something strange to colors too. Whites were bright as fresh-fallen snow, yellow shone like gold, reds turned to flame, but the shadows were so black they looked like holes in the world. Sam found himself staring. The candle itself was three feet tall and slender as a sword, ridged and twisted, glittering black. “Is that.?”

“. obsidian,” said the other man in the room, a pale, fleshy, pasty-faced young fellow with round shoulders, soft hands, close-set eyes, and food stains on his robes.

“Call it dragonglass.” Archmaester Marwyn glanced at the candle for a moment. “It burns but is not consumed.”

“What feeds the flame?” asked Sam.

“What feeds a dragon’s fire?” Marwyn seated himself upon a stool. “All Valyrian sorcery was rooted in blood or fire. The sorcerers of the Freehold could see across mountains, seas, and deserts with one of these glass candles. They could enter a man’s dreams and give him visions, and speak to one another half a world apart, seated before their candles. Do you think that might be useful, Slayer?”

“We would have no more need of ravens.”

“Only after battles.” The archmaester peeled a sourleaf off a bale, shoved it in his mouth, and began to chew it. “Tell me all you told our Dornish sphinx. I know much of it and more, but some small parts may have escaped my notice.”

He was not a man to be refused. Sam hesitated a moment, then told his tale again as Marywn, Alleras, and the other novice listened. “Maester Aemon believed that Daenerys Targaryen was the fulfillment of a prophecy. her, not Stannis, nor Prince Rhaegar, nor the princeling whose head was dashed against the wall.”

“Born amidst salt and smoke, beneath a bleeding star. I know the prophecy.” Marwyn turned his head and spat a gob of red phlegm onto the floor. “Not that I would trust it. Gorghan of Old Ghis once wrote that a prophecy is like a treacherous woman. She takes your member in her mouth, and you moan with the pleasure of it and think, how sweet, how fine, how good this is. and then her teeth snap shut and your moans turn to screams. That is the nature of prophecy, said Gorghan. Prophecy will bite your prick off every time.” He chewed a bit. “Still. ”

Alleras stepped up next to Sam. “Aemon would have gone to her if he had the strength. He wanted us to send a maester to her, to counsel her and protect her and fetch her safely home.”

“Did he?” Archmaester Marwyn shrugged. “Perhaps it’s good that he died before he got to Oldtown. Elsewise the grey sheep might have had to kill him, and that would have made the poor old dears wring their wrinkled hands.”

“Kill him?” Sam said, shocked. “Why?”

“If I tell you, they may need to kill you too.” Marywn smiled a ghastly smile, the juice of the sourleaf running red between his teeth. “Who do you think killed all the dragons the last time around? Gallant dragonslayers armed with swords?” He spat. “The world the Citadel is building has no place in it for sorcery or prophecy or glass candles, much less for dragons. Ask yourself why Aemon Targaryen was allowed to waste his life upon the Wall, when by rights he should have been raised to archmaester. His blood was why. He could not be trusted. No more than I can.”

“What will you do?” asked Alleras, the Sphinx.

“Get myself to Slaver’s Bay, in Aemon’s place. The swan ship that delivered Slayer should serve my needs well enough. The grey sheep will send their man on a galley, I don’t doubt. With fair winds I should reach her first.” Marwyn glanced at Sam again, and frowned. “You. you should stay and forge your chain. If I were you, I would do it quickly. A time will come when you’ll be needed on the Wall.” He turned to the pasty-faced novice. “Find Slayer a dry cell. He’ll sleep here, and help you tend the ravens.”

“B-b-but,” Sam sputtered, “the other archmaesters. the Seneschal. what should I tell them?”

“Tell them how wise and good they are. Tell them that Aemon commanded you to put yourself into their hands. Tell them that you have always dreamed that one day you might be allowed to wear the chain and serve the greater good, that service is the highest honor, and obedience the highest virtue. But say nothing of prophecies or dragons, unless you fancy poison in your porridge.” Marwyn snatched a stained leather cloak off a peg near the door and tied it tight. “Sphinx, look after this one.”

“I will,” Alleras answered, but the archmaester was already gone. They heard his boots stomping down the steps.

“Where has he gone?” asked Sam, bewildered.

“To the docks. The Mage is not a man who believes in wasting time.” Alleras smiled. “I have a confession. Ours was no chance encounter, Sam. The Mage sent me to snatch you up before you spoke to Theobald. He knew that you were coming.”

“How?”

Alleras nodded at the glass candle.

Sam stared at the strange pale flame for a moment, then blinked and looked away. Outside the window it was growing dark.

“There’s an empty sleeping cell under mine in the west tower, with steps that lead right up to Walgrave’s chambers,” said the pasty-faced youth. “If you don’t mind the ravens quork ing, there’s a good view of the Honeywine. Will that serve?”

“I suppose.” He had to sleep somewhere.

“I will bring you some woolen coverlets. Stone walls turn cold at night, even here.”

“My thanks.” There was something about the pale, soft youth that he misliked, but he did not want to seem discourteous, so he added, “My name’s not Slayer, truly. I’m Sam. Samwell Tarly.”

“I’m Pate,” the other said, “like the pig boy.”
