He must have slipped into a trance, or fallen asleep—he didn’t remember. He woke up to the sound of the man on stage singing softly and high under his breath. His voice was surprisingly tender:

“Bye, baby Bunting
Daddy’s gone a-hunting
Gone to get a rabbit skin
To wrap his baby Bunting in”

He lapsed into humming. Then, with no warning, he vanished.

It happened so silently and so suddenly that at first Quentin didn’t notice he was gone. In any case his departure was upstaged by Professor March, who’d been standing onstage the entire time with his mouth open. The instant the man was gone March crumpled forward bonelessly off the stage and knocked himself cold on the hardwood floor.

Quentin tried to stand up. Instead he slid off his chair, down onto the floor between the rows of seats. His arms, legs, and back were hideously cramped. There was no strength in them. Slowly, lying on the floor in a mixture of agony and relief, he stretched out his legs. Delicious bubbles of pain released in his knees, as if he were finally unbending them after a trans-hemispherical flight in coach. Tears of relief started in his eyes. It was over. The man was finally gone and nothing terrible had happened. Alice was groaning, too. A pair of shoes, probably hers, was in his face. The whole room rocked with moans and sobs.

Afterward Quentin would learn that Fogg had mustered the entire staff almost immediately, as soon as the man had made his appearance. The school’s defensive spells detected him instantly, even if they didn’t keep him out. By all accounts Fogg made a surprisingly competent battlefield commander: calm, organized, rapid and accurate in his assessment of the situation, skillful in his deployment of the resources at his disposal.

Over the course of the morning an entire temporary scaffold had been constructed around the outside of the tower. Professor Heckler, wearing a welder’s helmet to shield his eyes, had nearly set the tower on fire with pyrotechnical attacks. Professor Sunderland had heroically attempted to phase herself through the wall, but to no avail, and anyway it wasn’t clear what she would have done if she succeeded. Even Bigby made an appearance, deploying some exotic nonhuman witchcraft that—Quentin got the impression—had made the rest of the faculty a little uncomfortable.

That evening after dinner, after the usual announcements about clubs and events and activities had been sullenly and desultorily attended to, Dean Fogg addressed the student body to try to explain what had happened.

He stood at the head of the long dining room table, looking older than usual, as the candles guttered down and the First Years gloomily cleared the last of the silverware. He fussed with his cuffs and touched his temples where he was losing his thin blond hair.
