This was unexpected. Downstairs meant the cellar, where Quentin had almost never been in his whole time at Brakebills—just once or twice to sneak a particularly coveted bottle from the wine cellar, or when he and Alice had been desperate for privacy. But now Professor Fogg led them in a loose, bantering, occasionally singing flock back through the kitchen, through a small, unassuming door in the pantry, and down a flight of worn and dusty wooden stairs that changed midflight into stone. They emerged into a dark, earthy subbasement.

This wasn’t where Quentin had thought the party was going. It wasn’t a party atmosphere at all. It was cool down here and suddenly quiet. The floor was dirt, the ceilings were low, and the walls were bumpy and unfinished. They devoured sound. Voice by voice the chorus of a traditional Brakebills song—an elaborately euphemistic number entitled “The Prefect Has a Defect”—died away. There was a grave but not unpleasant smell of damp soil.

Fogg stopped at what looked like a manhole cover embedded in the dirt floor. It was brass and densely inscribed with calligraphic writing. Oddly, it looked as shiny and new as a freshly struck coin. The Dean picked up a heavy manhole tool and, with an effort, levered up the brass disk. It was two inches thick, and it took three of the Fifth Years to roll it to one side.

“After you,” the Dean said, panting a little. He gestured grandly at the inky black hole.

Quentin went first. He felt around blindly with his Scotch-benumbed feet till he found an iron rung. It was like lowering himself into warm black oil. The ladder took him and the other graduates straight down into a circular chamber large enough for all nineteen of them to stand upright in a circle, which they did. Fogg came down last; they could hear him screwing the manhole cover back into place behind them. Then he descended, too, and with a crash he sent the ladder retracting back up, like a fire escape. After that the silence was absolute.

“No point in losing our momentum,” Fogg said. He lit a candle and gamely produced two fifths of bourbon from somewhere and set them going in opposite directions around the circle. Something about this gesture unnerved Quentin. There was a certain amount of sanctioned alcohol consumption at Brakebills—a fairly large amount, really—but this was a bit much. There was something forced about it.

Well, it was graduation. They weren’t students anymore. They were grown-ups. Just peers, sharing a drink. In a secret underground dungeon, in the middle of the night. Quentin took his swig and passed it on.
