Clary could feel the wind suddenly change direction and the cold that flooded the area. She knew she shouldn't be here but when she got a message her curiosity got the better of her. The footsteps emanating from her position were louder than she wished they were, training or not, she wasn't ready for a true fight with demons yet. She shuddered at the thought of demons tearing her apart and she couldn't stop them, she was broken out of her reverie when a light appeared at the end of the alleyway. It was the most unusual light she had ever seen, it seemed to be two letter Cs and an arrow point in between them. When the light shifted she took a step back and tripped over the manhole that was behind her, the fall caused her to let out an involuntary gasp.

Just as she looked to the light again it moved faster than even Jace could, she could feel something against her neck and recognized the material. It was the same glassy substance they used to make Seraph Blades but it seemed stronger somehow. There were no arms to her attacker until she reached up, and came in contact with what she thought was a chest, the body materialized. A male no older than 19, crimson red eyes, broad shoulders, he seemed just a tad taller than Jace, black hair and the thing that scared Clary the most wasn't the fact that her assailant was holding a weapon to her throat it was the fact that the weapon was coming out of the top of his wrist.

He pulled back, offered a hand to Clary although she swatted it away. The man didn't seemed phased and just walked into the shadows and disappeared, after seeing that Clary got to her feet quickly and walked after him. Unfortunately she didn't disappear she just walked into a wall, her grunt after walking out was enough to alert Jace to her whereabouts seeing as though she had told him to wait for her near the street crossing. He came jogging over, his golden hair bouncing with each step.

"So what was it?" Jace took another step towards her and scanned the area for any demon activities.

"Nothing, come on. I don't think you'll get anything on the sensor."

"Oh look who thinks she's all smart now that we taught her the Shadowhunter language," Jace joked but got a death glare from Clary, he backed away like he was scared but the smirk on his face made Clary realize he wasn't.

She started walking out of the alleyway when Jace stopped her and pushed her up against a wall, "Jace!"

"Demon activity, I knew it," He reached into his belt and pulled out a Seraph Blade, he whispered its name and the light burst free, "What did you see?"

"A guy, I don't know… he didn't seem demon-ish to me," Jace gave her a look and she tried to smile, "Ok so I can't really tell yet."

"A man should never push a lady," A voice called out from the shadows, it seemed to have a very American accent to it with a dash of Russian.

Jace let Clary go and whirled round to face the voice but only saw the same light Clary saw in double, "What are you?"

"Very observant, a man is not a he but a something if his humanity has been taken away. I never had it," Both Shadowhunters stepped back as the voice emerged from the shadows and the man Clary had seen was standing there, "I believe introductions are in order, don't you?"

"How about I introduce my Seraph Blade to your spine?" Jace said, his voice had venom in it but something about the guy reminded her of how Sebastian acted against Jace's threats.

"No need to get so harsh, Herondale. I can see the mark on your shoulder and the mark on the Morgenstern daughter."

Clary almost gasped, this guy, whoever he is, knew who they were, "How do you know who we are?"

"Well, let me start by saying I hated Valentine just like most of you and that accursed mark along the Herondale's chest."

"You know about it?" Jace still had his Seraph blade aimed for the man but wasn't making any move to stop him speaking.

"Yes, I was one who had carried that mark for years but as all marks… they fade unlike my Looms. I am a Soul Weaver."

"You don't exist, the Soul Weaver's are a story that young Shadowhunters are told to inspire us to fight the way they did in the stories," Jace's hand was shaking slightly, Clary almost wanted to put a hand on his shoulder to help keep him steady.

"We exist, although I must say I'm the last. We were slaughtered by Valentine years ago… my name is Phantom and I should tell you that there is a Greater Demon right behind you," Just after he finished his sentence both Jace and Clary turned slightly to see the Greater Demon looming over them.
