Isabelle and Simon were checking Luke for injuries. Isabelle kept glancing back at Alec, her face anxious; Alec deliberately didn’t meet her gaze, not wanting her to see the fear in his eyes. He touched the back of his hand to Magnus’s face.

Magnus looked sunken and sallow, his lips dry, ashy shadows beneath his eyes.

My Alec, Magnus had said, you’ve been so sad. I didn’t know. And then he had sunk back against the floor, as if the effort of speaking exhausted him.

“Hold still,” Alec said now, and drew a seraph blade from his belt. He opened his mouth to name it, and felt a sudden touch at his wrist. Magnus had wrapped his slender fingers around Alec’s wrist.

“Call it Raphael,” Magnus said, and when Alec looked at him in puzzlement, Magnus glanced toward the blade in Alec’s hand. His eyes were half-closed, and Alec remembered what Sebastian had said in the entryway, to Simon: I killed the one who made you. Magnus’s mouth quirked at the corner. “It is an angel’s name,” he said.

Alec nodded. “Raphael,” he said softly, and when the blade blazed up, he brought it down hard on the adamas chain, which splintered under the touch of the knife. The chains fell away, and Alec, dropping the blade to the floor, reached forward to take Magnus by the shoulders and help him up.

Magnus reached for Alec, but instead of rising to his feet, he pulled Alec against him, his hand sliding up Alec’s back to knot in his hair. Magnus pulled Alec down and against him, and kissed him, hard and awkward and determined, and Alec froze for a moment and then abandoned himself to it, to kissing Magnus, something he’d thought he’d never get to do again. Alec ran his hands up Magnus’s shoulders to the sides of his neck and cupped his hands there, holding Magnus in place while he kissed him thoroughly breathless.

Finally Magnus drew back; his eyes were shining. He let his head fall onto Alec’s shoulder, arms encircling him, keeping them tightly together. “Alec . . . ,” he began softly.

“Yes?” Alec said, desperate to know what Magnus wanted to ask him.

“Are you being chased?”

“I—ah—some of the Endarkened are looking for us,” Alec said carefully.

“Pity,” Magnus said, closing his eyes again. “It would be nice if you could just lie down with me here. Just . . . for a little while.”

“Well, you can’t,” said Isabelle, not unkindly. “We have to get out of here. The Endarkened will be here any second, and we’ve got what we came for—”

“Jocelyn.” Luke drew away from the wall, straightening up. “You’re forgetting Jocelyn.”

Isabelle opened her mouth, then closed it again. “You’re right,” she said. Her hand went to her weapons belt, and she unfastened a sword; taking a step across the room, she handed it to Luke, then bent down to pick up Alec’s still-burning seraph blade.

Luke took the sword and held it with the careless competence of someone who had handled blades all their life; sometimes it was hard for Alec to remember that Luke had been a Shadowhunter once, but he remembered now.

“Can you stand?” Alec said to Magnus gently, and Magnus nodded, and let Alec lift him to his feet.

He lasted almost ten seconds before his knees buckled and he collapsed forward, coughing. “Magnus!” Alec exclaimed, and threw himself down by the warlock’s side, but Magnus waved him away and struggled up to his knees.

“You should go without me,” he said, in a voice made gravelly by hoarseness. “I’ll slow you down.”

“I don’t understand.” Alec felt as if a vise were compressing his heart. “What happened? What did he do to you?”

Magnus shook his head; it was Luke who answered. “This dimension is killing Magnus,” he said, voice flat. “There’s something about it—about his father—that’s destroying him.”

Alec glanced at Magnus, but Magnus only shook his head again. Alec fought down an irrational burst of anger—still withholding things, even now—and took a deep breath. “The rest of you go find Jocelyn,” he said. “I’ll stay with Magnus. We’ll head toward the center of the keep. When you find her, come looking for us there.”

Isabelle looked wretched. “Alec—”

“Please, Izzy,” said Alec, and he saw Simon put his hand on Isabelle’s back, and whisper something into her ear. She nodded, finally, and turned toward the door; Luke and Simon followed her, both pausing to look back at Alec before they went, but it was the image of Izzy that stuck in his mind, carrying her blazing seraph blade in front of her like a star.

“Here,” he said to Magnus as gently as he could, and reached down to lift him up. Magnus stumbled to his feet, and Alec managed to get one of the warlock’s long arms slung over his shoulder. Magnus was thinner than he had ever been; his shirt clung to his ribs, and the spaces under his cheekbones looked sunken, but there was still a lot of warlock to contend with: a lot of skinny arms and legs and long, bony spine.

“Hold on to me,” Alec said, and Magnus gave him the sort of smile that made Alec feel like someone had taken an apple corer to his heart and tried to dig out the center.

“I always do, Alexander,” he said. “I always do.”

The baby had fallen asleep in Julian’s lap. He was holding Tavvy tightly, carefully, great dark hollows under his eyes. Livvy and Ty were huddled together on one side of him, Dru curled against him on the other.

Emma sat behind him, her back against his, giving him something to lean on to balance the weight of the baby. There were no free pillars to sit against, no bare space of wall; dozens, hundreds of children were prisoned in the Hall.

Emma leaned her head back against Jules’s. He smelled the way he always did: soap, sweat, and the tang of ocean, as if he carried it in his veins. It was comforting and not comforting in its familiarity. “I hear something,” she whispered. “Do you?”

Julian’s eyes flicked immediately to his brothers and sisters. Livvy was half-asleep, her chin propped on her hand. Dru was looking all around the room, her big blue-green eyes taking everything in. Ty was tapping his finger against the marble floor, obsessively counting from one to a hundred and backward again. He had kicked and screamed when Julian had tried to look at a welt on his arm where he had fallen. Jules had let it go, and allowed Ty to go back to his counting and rocking. It soothed him to quietness, which was what mattered.

“What do you hear?” Jules asked, and Emma’s head fell back then as the sound rose, a sound like a great wind or the crackle of a massive bonfire. People started to move and cry out, looking up at the glass ceiling of the Hall.

Through it clouds were visible, moving across the face of the moon—and then from the clouds burst a wild assortment of riders: riders of black horses, whose hooves were flame, riders of massive black dogs with orange-burning eyes. More modern forms of transport were mixed in as well—black carriages drawn by skeletal steeds, and motorcycles gleaming with chrome and bone and onyx.

“The Wild Hunt,” Jules whispered.

The wind was a living thing, whipping the clouds into peaks and valleys that the horsemen hurtled up and down, their cries audible even over the gale, their hands bristling with weapons: swords and maces and spears and crossbows. The front doors of the Hall began to shake and tremble; the wooden bar that had been placed across them exploded into splinters. The Nephilim stared toward the doors with terrified eyes. Emma heard the voice of one of the guards among the crowd, speaking in a harsh whisper:
