and scarlet, and washed the color from Alec’s face as he walked next to Magnus, quiet and seemingly lost in thought.
The room was probably an office, in the real cathedral, but here in Diyu it was just another empty box, with a marble floor and whitewashed stone walls.
“Cozy,” said Alec. “Do you think you could summon some comfy blankets?”
Magnus cocked an eyebrow. “From where, exactly? I got the rice and water from offerings to the dead, but the pickings are slim down here for luxury items.”
Alec shrugged. “The… Hell of Comfy Blankets?”
Magnus thought. “I could… summon one of those nine-headed birds and we could try to pull off its feathers? No, they probably wouldn’t smell very good. Wait.”
“What?”
Magnus giggled to himself and summoned himself a blanket from the one place in Diyu whose occupant he knew would prioritize a pleasant sleep experience.
A red brocade duvet popped into the room, in a puff of crimson smoke. It was lined with gold tassels.
“Is it a coincidence,” said Alec, “that the duvet is the same color as your magic?”
“I… don’t know,” said Magnus.
He summoned a couple of pillows as well. Alec looked pleased.
They settled themselves down on the ground and placed themselves in their usual sleeping positions. Strange things, sleeping positions, Magnus thought. They get set at the beginning of a relationship, when nobody is thinking about it, and then they are set forever. But now it was true: if Magnus was in bed, as long as Alec was lying directly to his right, there was something of home, wherever he was.
“Before you put out the light,” Alec said.
Magnus waited for the rest, but when it didn’t come, he said, “Yes?” Alec looked hesitant. “What is it?” He was beginning to be a little alarmed.
“Before you go tomorrow… to be bait.”
Magnus blinked a few times. “Are you having trouble finishing your thoughts?”
“No,” said Alec, sounding put out. “I think we should use the Alliance rune.”
“What Alliance rune?”
“The Alliance rune,” Alec said. “Clary’s Alliance rune. That allows a paired Shadowhunter and Downworlder to share power.”
Clary had invented the Alliance rune three years ago, in the Mortal War, to give Shadowhunters and Downworlders the ability to fight as a pair, sharing their skills and their strengths. Magnus vividly remembered the eve of battle years ago. He’d been jangling with nerves, the prospect of death on the battlefield before him, and he’d felt heavy with sorrow. He’d told this young Shadowhunter he loved him, but he didn’t know how that Shadowhunter truly felt about him, whether their relationship could endure or whether it was as impossible as he feared.
He’d watched the rune forming on his own skin, the intricate lines and curves of an angelic rune something he never would have thought he would bear.
But now—now it was Magnus’s turn to say, “No.”
“You don’t have to do this alone,” insisted Alec. “You should take some of my strength. I should take some of the burden of the thorn.”
“We have no idea what it would do,” said Magnus. “What it would mean for you to take some of this weird magic. It’s connected to Sammael somehow, and you’re full of, you know, angel magic. You might explode.”
Alec blinked. “I probably wouldn’t explode.”
“Who knows what could happen? Neither of us is exactly an expert on this particular magical artifact.”
“Still,” said Alec mulishly. “I think we should do it.” When Magnus didn’t say anything, he added, “If I’m going to let you go out there and demand to be attacked, at least let me share some of the burden with you.”
Magnus looked into Alec’s eyes. “If something happens to me,” he said very quietly, “Max will need you.”
“If we put the rune on and something’s going wrong,” said Alec, “we’ll scratch it out. It’ll be fine.”
Magnus sighed. “I have to give in on this,” he said, “because I said ‘it’ll be fine’ about the bait thing and you agreed, right?”
“There are some who would consider that a valid argument, yes,” said Alec.
Magnus stretched out his arm. “Okay. Why not one more totally irresponsible thing before we close out the day?”
Alec drew the strokes of the rune with attentive care, and Magnus felt the same wonder as he had years ago, the same calming of fear. On the eve of battle, amid the darkened spin of a strange infernal city: it made no difference where they were. They would fight and live and die together.
As Alec finished the last loop of the rune on his own skin, Magnus watched him
