Magnus Bane rose out of his chair and walked to the window, looking out at Brooklyn. There was a knock on his door, but he made no move to answer it.
"Magnus, I know you're in there!" a voice called over the intercom a few seconds later.
He sighed. He knew that voice, and he also knew that it's owner would not go away until he answered it.
Magnus went to the door. He opened to find that he was right; Alec Lightwood was standing in the doorway.
"Magnus, we need your help," he said.
Magnus looked at Alec. The younger boy looked very worried. "What happened?"
"It's Jace. We don't know what happened. But he was found outside the Institute, unconscious, barely breathing."
