Now he floated through Professor March’s lectures from the back row, feeling lofty contempt for his classmates, who were only on Popper etude No. 27, when he had already scaled the glorious heights of No. 51 and watched it grow tiny beneath his still-climbing feet. He began to hate the the grungy misshapen room where he and Penny and Alice did their late-night cramming. He hated the bitter, burned smell of the coffee they drank, to the point where he almost felt tempted to try the low-grade speed Penny took as an alternative. He recognized the irritable, unpleasant, unhappy person he was becoming: he looked strangely like the Quentin he thought he’d left behind in Brooklyn.

Quentin didn’t do all his studying in the trapezoidal spare room. On weekends he could work wherever he wanted, at least during the daytime. Mostly he stayed in his own room, but sometimes he climbed the long spiral staircase up to the Brakebills observatory, a respectable if antiquated facility at the top of one of the towers. It contained a massive late-nineteenth-century telescope the size of a telephone pole, poking up at an angle through a tarnished copper dome. Somebody on the staff must have been deeply in love with this obsolete instrument, because it floated on an exquisitely complicated array of brass gears and joints that was kept freshly oiled and in a state of high polish.

Quentin liked to read in the observatory because it was high up and well heated and relatively unfrequented: not only was it hard to get to, the telescope was useless during the day. This was usually enough to secure him an afternoon of lofty, wintry solitude. But on one Saturday in late November he discovered that he wasn’t the only one who’d figured this out. When Quentin reached the top of the spiral staircase, the trapdoor was already open. He poked his head up into the circular, amber-lit room.

It was like he’d poked his head into another world, an alien planet that looked eerily like his own, but rearranged. The interloper was Eliot. He was kneeling like a supplicant in front of an old orange armchair with ripped upholstery that stood in the middle of the room, in the center of the circular track that the telescope ran on. Quentin always wondered who had gotten the chair up there in the first place and why they’d bothered—magic was obviously involved, since it wouldn’t have fit through the trapdoor, or even any of the tiny windows.

Eliot wasn’t alone. There was somebody sitting in the chair. The angle was bad, but he thought it was one of the Second Years, an unexceptional, smooth-cheeked kid with straight rust-colored hair. Quentin barely knew him. His name might have been Eric.

“No,” Eric said, and then again sharply: “No! Absolutely not.” He was smiling. Eliot started to stand up, but the boy held him down playfully by his shoulders. He wasn’t especially large. The authority he exercised over Eliot wasn’t physical.
