Time passed, or at least Quentin knew that, according to theory, it pretty much had to be passing, though he didn’t personally see much evidence of it, unless you counted the weird menagerie of mustaches and beards he and his male classmates were growing. However much he ate he got thinner and thinner. His state of mind devolved from mesmerized to hallucinatory. Tiny random things became charged with overwhelming significance—a round pebble, a stray straw from a broom, a dark mark on a white wall—that dissipated again minutes later. In the classroom he sometimes saw fantastical creatures mixed in with his classmates—a huge, elegant brown stick insect that clung to the back of a chair; a giant lizard with horny skin and a German accent, whose head burned with white fire—though afterward he could never be sure if he had imagined them. Once he thought he saw the man whose face was hidden by a branch. He couldn’t take this much longer.

Then, just like that, one morning over breakfast Mayakovsky announced that there were two weeks remaining in the semester, and it was time they gave serious thought to the final exam. The test was simply this: they would walk from Brakebills South to the South Pole. The distance was on the order of five hundred miles. They would be given no food and no maps and no clothing. They would have to protect and sustain themselves by magic. Flying was out of bounds—they would go on foot or not at all, and in the form of human beings, not as bears or penguins or some other naturally cold-resistant animal. Cooperation between students was prohibited—they could view it as a race, if they liked. There was no time limit. The exam was not mandatory.

Two weeks wasn’t quite long enough to prepare properly, but it was more than long enough for the decision to hang over them. Yes or no, in or out? Mayakovsky stressed that safety precautions would be minimal. He would do his best to keep track of them in the field, but there was no guarantee that if they screwed up he’d be able to rescue their sorry, hypothermic asses.

There was a lot to study up on. Would sunburn be a problem? Snow blindness? Should they toughen the soles of their feet or try to create some kind of magical footwear? Was there any way to get mutton fat, which they could need to cast Chkhartishvili’s Enveloping Warmth, from the kitchen? And if the test wasn’t even mandatory, then what was the point of it? What would happen if they failed? It sounded more like a ritual or a hazing than a final exam.
