They made camp that night in the ruins of a town whose name no one remembered.
The buildings were shells, their roofs collapsed, their walls scarred by fire and claw. In the center of the town, a fountain still stood, its basin filled with water that was clear but tasted of iron. Marok set his men to watch in shifts, four at a time, their torches casting long shadows that danced in the twilight.
Elyss found Kaelen at the fountain, washing the black fluid from his hands.
"You knew it was there," she said. "The Tall One. You knew it would be waiting."
He did not look up. "I knew something would be waiting. The closer we get to the North, the more they will find us."
She sat on the edge of the fountain, her white robes grey with ash, her face drawn with exhaustion. "What did it mean when it said you were the one who opened the door?"
Kaelen stopped washing his hands. The water dripped from his fingers, black and red and grey.
"I touched the Breach," he said. "Four years ago. I touched it, and the Rot spread. The Unmade came. The twilight deepened. That is what it meant."
"That's not what it meant." She leaned forward, her eyes fixed on his face. "It called you the Breach. Not the one who opened it. The Breach itself. And Seren—she said your name was written in texts three thousand years old. That someone planned this."
"And you believe her? The mad scholar who talks to the walls?"
Elyss was quiet for a moment. Then she reached into her robes and drew out the vial. In the torchlight, the darkness inside seemed to move, to pulse, to reach toward him.
"I believe that something has been waiting for you," she said. "And I believe that when you touched the Breach, it got what it wanted."
Kaelen looked at the vial. Then he looked at her.
"Why did you come?" he asked. "The Church sent you to watch me. To use that if I became a threat. But you could have stayed in Valerion. You could have waited for me to die in the North, like everyone else. So why did you come?"
She met his gaze. In the flickering torchlight, her eyes were the color of the twilight sky.
"Because I want to know the truth," she said. "Before the Church decides what to do with it. Before they take it and twist it and use it to make people afraid. I want to know what happened. And I want to know if there's any way to undo it."
She held out the vial.
"You said this would make you worse. That it would finish what the North started. But you didn't say it would kill you. You didn't say it would turn you into one of them."
"It wouldn't."
"Then what would it do?"
He took the vial from her hand. It was cold, colder than the air, colder than the water in the fountain. The darkness inside swirled, reaching toward his fingers like a living thing.
"It would make me remember," he said. "Everything. The North. The Breach. What I saw on the other side. Everything I have been trying to forget for four years."
He held it up to the torchlight. The liquid inside caught the flame, reflected it back in colors that should not exist.
"I touched the door," he said quietly. "And on the other side, something was waiting. Something vast. Something old. Something that had been waiting for the sun to die so it could come through." He lowered the vial, looked at Elyss. "When I touched it, it didn't just open the door. It reached through. It touched me. And since that day, part of it has been inside me. Waiting. Watching. Growing."
He pressed the vial back into her hand.
"That is what the Binding is. Not a power I can use. It is the thing that lives behind my eyes, whispering, waiting for me to let it out. And if I let it out—" He smiled, and it was not a pleasant expression. "Then there will be no more Kaelen. Only the Breach. Only the door. Only the thing that killed the sun."
Elyss stared at the vial in her hand. Then she looked at Kaelen—at the lines on his face, the shadows under his eyes, the weight that he carried every moment of every day.
"How do you keep fighting?" she asked. "Knowing that. How do you keep going?"
He stood, his cloak dripping water, his hands still stained with black.
"Because I made a promise," he said. "To the men I led north. To the ones who didn't come back. To the ones who became what you see out there." He gestured at the darkness beyond the camp, where the Unmade waited. "I told them I would close the door. And I will. Even if it kills me. Even if it makes me one of them."
He walked away, toward the edge of camp, where Toren was waiting with his sword drawn and his eyes watching the darkness.
Elyss sat alone at the fountain, the vial in her hands, and wondered if she had just watched a man walk toward his death.
Or toward something worse.
