None of them had any exact memory of how Quentin had gotten here. They didn’t pay close attention to the backstory of the occasional damaged human who fetched up in their midst. When pressed, Quentin’s doctor, a terrifyingly earnest individual whose name was Alder Acorn Agnes Allison-fragrant-timber, said she vaguely remembered some humans, unusually filthy and bedraggled specimens, now that you mention it, bringing Quentin in on a makeshift litter. He’d been unconscious and deep in shock, with his rib cage crushed and one of his forelimbs badly dislocated, practically detached. Such anatomical disorder was distasteful to the centaurs. And they were not insensible of the service the humans had rendered to Fillory in ridding it of Martin Chatwin. They did their best to render assistance.

The humans lingered in the area for a month, maybe two, while the centaurs wove deep webs of wood-magic around Quentin’s torn, bruised, insulted body. But they thought it unlikely that he would ever wake up. And in time, as Quentin showed no signs of recovering consciousness, the humans reluctantly departed.

He supposed he could have been angry that they had left him there, in Fillory, with no way of returning to his own world. But all he felt was warm, cowardly relief. He didn’t have to face them. The sight of their faces would have burned the skin right off him with shame. He wished he had died, and if he couldn’t have death, at least he had this, the next best thing: total isolation, lost forever in Fillory. He was broken in a way that magic could never fix.

His body was still weak, and he spent a lot of time in bed, resting his atrophied muscles. He was an empty shell, roughly hollowed out by some crude tool, gutted and left there, a limp, raw, boneless skin. If he tried, he could summon up old sense-memories. Nothing from Fillory or Brakebills, just the really old stuff, the easy stuff, the safe stuff. The smell of his mother’s oil paints; the lurid green of the Gowanus Canal; the curious way Julia pursed her lips around the reed of her oboe; the hurricane that blew through when they took that family vacation in Maine, he must have been about eight, when they went out on the lawn and threw their sweaters in the air and watched them sail away over the neighbor’s fence and then fell down laughing. A beautiful blossoming white cherry tree stood outside his window in the warm afternoon sunlight. Every part of it moved and swayed in a slightly different rhythm from every other part. He watched it for a long time.
