“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. 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.”

“I know what I saw. The light was queer and bright, much brighter than any beeswax or tallow candle. It cast strange shadows and the flame never flickered, not even when a draft blew through the open door behind me.”

Armen crossed his arms. “Obsidian does not burn.”

“Dragonglass,” Pate said. “The smallfolk call it dragonglass.” Somehow that seemed important.

“They do,” mused Alleras, the Sphinx, “and if there are dragons in the world again . . .”

“Dragons and darker things,” said Leo. “The grey sheep have closed their eyes, but the mastiff sees the truth. Old powers waken. Shadows stir. An age of wonder and terror will soon be upon us, an age for gods and heroes.” He stretched, smiling his lazy smile. “That’s worth a round, I’d say.”

“We’ve drunk enough,” said Armen. “Morn will be upon us sooner than we’d like, and Archmaester Ebrose will be speaking on the properties of urine. Those who mean to forge a silver link would do well not to miss his talk.”
