Like a sequined assistant, Alice stepped up to an end table on the green, placed an empty wine bottle on it, and stepped away.

Facing the bottle, Penny took a quick breath and spoke a rapid sequence of clipped syllables under his breath, ending with a one-handed flicking gesture. Something—a spray of three somethings, steely gray and tightly grouped—shot out of his fingertips, too fast to follow, and flickered across the lawn. Two of them missed, but one of them snapped the bottle’s neck off cleanly, leaving the base standing headlessly upright.

Penny grinned. There was scattered applause.

“We call it ‘Magic Missile,’ ” he said.

“Magic Missile, baby!” Josh’s breath steamed in the cold air. His face was radiant with excitement. “That’s straight up Dungeons & Dragons shit!”

Penny nodded.

“We actually based some of this on old D & D spells. There’s a lot of practical thinking in those books.”

Quentin wasn’t smiling. Wasn’t anybody going to say anything? This was dark magic. God knows he wasn’t a prude, but this was a spell meant to break up flesh, to physically wound. They were crossing so many lines it was hard to figure out where they were anymore. If they ever actually had to cast this stuff, it would already be too late.

“God, I hope we don’t have to use that,” was all he said out loud.

“Oh, come on, Quentina. We’re not looking for trouble. We just want to be ready if it comes.” Josh could hardly contain himself. “Dungeons & Dragons, motherfucker!”

Next Alice whisked the card table away so that Penny stood alone, facing the dark line of lindens. The others stood and sat scattered behind him, under the empty sunset sky. The sun was almost down now. Their noses were running and their ears were red, but the cold didn’t seem to bother Penny, who was still wearing only a T-shirt and sweatpants. They were really in the middle of nowhere. Quentin was used to the background blare and hum of Manhattan, and even at Brakebills there were so many people around, there had always been someone somewhere yelling or knocking something over or blowing something up. Here, when the wind wasn’t sighing moodily in the trees, there was nothing. The whole world was on mute.

He tied down the earflaps of his Russian hat with a string.

“If this doesn’t work—” Penny began.

“Just do it already!” Janet said. “It’s cold out here!”

Penny did a deep knee-bend and spat on the gray-brown grass. Then he executed a grotesque, wild-armed flailing movement, at odds with what Quentin had seen of his otherwise highly disciplined style. Violet light sputtered in his cupped hands in the darkness so that the bones in his fingers were visible through the skin. He shouted something and finished with an overarm pitching motion.
