“We don’t know that he’s done anything to them. But—they are missing,” Jace said quietly, and Alec looked away, as if he couldn’t bear to meet their gazes.

“Veni,” Isabelle whispered, looking at the dais. “Why . . . ?”

“He’s telling us he has power,” Clary said. “Power none of us even begin to understand.” She thought of the way he’d appeared in her room and then disappeared. Of the way the ground had opened under his feet at the Citadel, as if the earth were welcoming him in, hiding him from the threat of the world above.

A sharp report rang out through the room, the bell that called the Council to order. Jia had moved to the lectern, an armed Clave guard in hooded robes on either side of her.

“Shadowhunters,” she said, and the word echoed as clearly through the room as if she’d used a microphone. “Please be silent.”

The room subsided gradually into quiet, though from the rebellious looks on quite a few faces, it was an uncooperative quiet. “Consul Penhallow!” called out Kadir. “What answers do you have for us? What is the meaning of this—this desecration?”

“We’re not sure,” said Jia. “It happened in the night, in between one watch of guards and another.”

“This is vengeance,” said a thin, dark-haired Shadowhunter whom Clary recognized as the head of the Budapest Institute. Lazlo Balogh, she thought his name was. “Vengeance for our victories in London and at the Citadel.”

“We didn’t have victories in London and at the Citadel, Lazlo,” said Jia. “The London Institute turned out to be protected by a force even we were unaware of, one we cannot replicate. The Shadowhunters there were warned and led to safety. Even then, a few were injured: None of Sebastian’s forces were harmed. At best it could be called a successful retreat.”

“But the attack on the Citadel,” Lazlo protested. “He did not enter the Citadel. He did not reach the armory there—”

“But neither did he lose. We sent through sixty warriors, and he killed thirty and injured ten. He had forty warriors, and he lost perhaps fifteen. If it hadn’t been for what happened when he wounded Jace Lightwood, his forty would have slaughtered our sixty.”

“We’re Shadowhunters,” said Nasreen Choudhury. “We are used to defending that which we must defend with our last breaths, our last drops of blood.”

“A noble idea,” said Josiane Pontmercy, from the Marseilles Conclave, “but perhaps not entirely practical.”

“We were too conservative in the number we sent to face him at the Citadel,” said Robert Lightwood, his booming voice carrying through the room. “We have estimated since the attacks that Sebastian has four hundred Endarkened warriors on his side. Simply given the numbers, a head-to-head battle now between his forces and all Shadowhunters would mean that he would lose.”

“So what we need to do is fight him as soon as possible, before he Turns any other Shadowhunters,” said Diana Wrayburn.

“You can’t fight what you can’t find,” said the Consul. “Our attempts to track him continue to prove fruitless.” She raised her voice. “Sebastian Morgenstern’s best plan now is to lure us out in small numbers. He needs us to send out scouting parties to hunt demons, or to hunt him. We must stay together, here, in Idris, where he cannot confront us. If we split up, if we leave our homeland, then we will lose.”

“He’ll wait us out,” said a blond Shadowhunter from the Copenhagen Conclave.

“We have to believe he doesn’t have the patience for that,” said Jia. “We have to assume he will attack, and when he does, our superior numbers will defeat him.”

“There’s more than patience to be considered,” said Balogh. “We left our Institutes, we came here, with the understanding that we would be returning once we had held a Council with the Downworld representatives. Without us out in the world, who will protect it? We have a mandate, a mandate from Heaven, to protect the world, to hold back the demons. We cannot do that from Idris.”

“All the wards are at full strength,” said Robert. “Wrangel Island is working overtime. And given our new cooperation with Downworlders, we will have to rely on them to keep the Accords. That was part of what we were going to discuss at the Council today—”

“Well, good luck to you with that,” said Josiane Pontmercy, “considering that the representatives of Downworld are missing.”

Missing. The word fell into the silence like a pebble into water, sending out ripples through the room. Clary felt Alec stiffen, minutely, at her side. She hadn’t been letting herself think about it, hadn’t been letting herself believe that they could really be gone. It was a trick Sebastian was playing on them, she kept telling herself. A cruel trick, but nothing more.

“We don’t know that!” Jia protested. “Guards are out searching now—”

“Sebastian wrote on the floor in front of their very seats!” shouted a man with a bandaged arm. He was the head of the Mexico City Institute and had been at the Citadel battle. Clary thought his last name was Rosales. “Veni. ‘I am come.’ Just as he sent us a message with the death of the angel in New York, now he strikes at us in the heart of the Gard—”

“But he didn’t strike at us,” Diana interrupted. “He struck at the representatives of Downworld.”

“To strike at our allies is to strike at us,” called Maryse. “They are members of the Council, with all the attendant rights that represents.”

“We don’t even know what happened to them!” snapped someone in the crowd. “They could be perfectly all right—”

“Then where are they?” shouted Alec, and even Jace looked startled to hear Alec raise his voice. Alec was glowering, his blue eyes dark, and Clary was suddenly reminded of the angry boy she had met in the Institute what felt like so long ago. “Has anyone tried to track them?”

“We have,” said Jia. “It hasn’t worked. Not all of them can be tracked. You cannot track a warlock, or the dead—” Jia broke off with a sudden gasp. Without warning the Clave guard on her left had come up behind her and seized her by the back of her robes. A shout ran through the assembly as he yanked her back, placing the blade of a long, silver dagger against her throat.

“Nephilim!” he roared, and his hood fell away, showing the blank eyes and swirling, unfamiliar Marks of the Endarkened. A roar began to rise from the crowd, cut off quickly as the guard dug his blade farther into Jia’s throat. Blood bloomed around it, visible even from a distance.

“Nephilim!” the man roared again. Clary’s mind struggled to place him—he seemed somehow familiar. He was tall, brown-haired, probably around forty. His arms were thickly muscled, the veins standing out like ropes as he struggled to hold Jia still. “Stay where you are! Do not approach, or your Consul dies!”

Aline screamed. Helen had hold of her, visibly restraining her from running forward. Behind them the Blackthorn children huddled around Julian, who was carrying his youngest brother in his arms; Drusilla had her face pressed against his side. Emma, her hair bright even at a distance, stood with Cortana out, protecting the others.
