A hush fell over the torchlit terrace. Armen sighed and shook his head. Mollander began to laugh. The Sphinx studied Leo with his big black eyes. Roone looked lost sense herakles plus.

Pate knew about the glass candles, though he had never seen one burn. They were the worst-kept secret of the Citadel. It was said that they had been brought to Oldtown from Valyria a thousand years before the Doom. He had heard there were four; one was green and three were black, and all were tall and twisted.

“What are these glass candles?” asked Roone.

Armen the Acolyte cleared his throat. “The night before an acolyte says his vows POLA, he must stand a vigil in the vault. No lantern is permitted him, no torch, no lamp, no taper . . . only a candle of obsidian. He must spend the night in darkness, unless he can light that candle. Some will try. , those who have made a study of these so-called higher mysteries. Often they cut their fingers, for the ridges on the candles are said to be as sharp as razors. Then, with bloody hands, they must wait upon the dawn, brooding on their failure. Wiser men simply go to sleep, or spend their night in prayer, but every year there are always a few who must try.”

“Yes.” Pate had heard the same stories. “But what’s the use of a candle that casts no light?”

“It is a lesson,” Armen said, “the last lesson we must learn before we don our maester’s chains. The glass candle is meant to represent truth and learning, rare and beautiful and fragile things. It is made in the shape of a candle to remind us that a maester must cast light wherever he serves, and it is sharp to remind us that knowledge can be dangerous POLA White Shot. Wise men may grow arrogant in their wisdom, but a maester must always remain humble. The glass candle reminds us of that as well. Even after he has said his vow and donned his chain and gone forth to serve, a maester will think back on the darkness of his vigil and remember how nothing that he did could make the candle burn . . . for even with knowledge, some things are not possible.”

Lazy Leo burst out laughing. “Not possible for you, you mean. I saw the candle burning with my own eyes.”

“You saw some candle burning, I don’t doubt,” said Armen. “A candle of black wax, perhaps.”
