Chapter 1- Seraphina

"Jace, Clary, Alec get your stuff, there has been a demon attack!" Isabelle shouted as she ran to the weapons room.

After last year, they had all been getting on with their lives as Shadowhunters and doing what they did best. There had been regular attacks in the city from demons that they had to tend to, but nothing as serious as this.

"There are around a dozen in an alley, Simon said he'd pick us up and take us there so you better hurry up!" Isabelle was all suited up and was waiting by the lift.

Alec was the first to meet her outside the lift with his bow and arrow and his hair wet and stringy as if he had just come out of the shower. He wore the usual black top with black jeans and a leather jacket and he was just finishing a strength rune on his forearm. A few seconds later, he was followed by Jace and Clary who were arguing with each other. They had been arguing a lot lately and it was usually about little things, like who should have the seraph blade and who should just carry a normal sword. Alec and Isabelle both shook their heads as they got in the lift and made their way to the gate outside the institute where Simon was waiting for them. He turned and smiled once he saw Isabelle. She noticed that he had cut his hair so that the curls were closer to his head and the white shirt he wore was stained with dirt. They had decided that they would take their relationship slow, but she didn't know whether to hug him or not. She ended up just smiling at him and saying hello as they all got into the white van and made their way to the location of the attack.

The van stopped outside an alley that was lined with closed down buildings and filled with thick smoke with the familiar smell of demons. As they got out of the van, Jace took out his seraph blade, Clary drew a sword out of its sheath, Alec got his bow and arrow ready and Isabelle allowed her whip to uncoil from around her wrist and fall into her hand. The van drove off while they walked in a line, Isabelle's heals were the only noise heard until they got deeper into the smoke, where they heard the wines and growls of many demons and the slashing of a blade against skin. Isabelle had to squint to see a figure dressed in a black dress with purple converses and tanned skin dispatching the demons one by one. Isabelle looked at the others to see that they were all making the exact same face as her- the face of bewilderment. Apart from Jace, she had never seen someone singlehandedly take on some of the biggest demons. The girl was fighting Arachne Demons with eight limbs and poison dripping off their sharp fangs, Acanthus Demons that had the thinnest but deadliest spikes all over their bodies and Renu Demons that turned into dust to move with the speed of light then become tall black monsters with mouths on their hands. The only weapons the girl was armed with was a double sided sword with blades that were made of aquamarine glass and what looked like a blade that was curved to have the shape of a boomerang. As Isabelle took a step forward, the girl threw her boomerang blade so that it span in a circle, narrowly missing Isabelle. The boomerang took most of the demons heads clean off, leaving only two for the girl to make quick work of, which only took a few swipes of her sword. Every demon has been killed and there was a silence as the girl lowered her sword, caught her boomerang and breathed heavily, allowing her chocolate brown curly hair to dance with the wind across her face.

"Sorry, I beat you to it," she laughed as she caught her breath.

Isabelle analysed her as if she were a painting in the institute. She was tall like her but not as slim- she was curvier, she's probably a size 8 or 10 she thought. She wore black leather gloves and bracelets and wrist bands decorated her arms like baubles on a Christmas tree. Her lips were rouged and she had green eyes and cheeks that were rounded. The girl had an English accent like Jace's, her voice even carried a hint of cockiness like him as well.

"Who are you?" Clary asked,

"Someone you wish you knew," the girl smiled as she walked towards the buildings to the left.

She took out a black crystal steele with roses snaked around it from a pocket in her dress and began to draw a rune onto the wall. A portal appeared and before they could say anything, the girl jumped into it leaving them in the alley contemplating what had just happened.

Alec didn't understand what had just happened. Usually there's a girl half dead begging for their help and they save her by killing the demons together, not a girl who effortlessly dispatches them. He looked at Jace who was standing to his left, not even he had words to say and he can usually say something about everything. Clary was the first to make a move and walk up to the portal that was still swirling. The wind from the portal blew her red hair back and made her black leather jacket look like wings.

"Are we gonna just stand here or follow her?" Clary asked looking at them.

Alec usually disagreed with all her ideas, but he wanted to know where the girl had come from. He had only ever seen Clary create a portal, so how could she? A nod from him was the signal for Clary to jump into the portal and for the rest to follow with Alec behind them.

When Alec stepped out of the portal next to Jace, the girl stood in front of them and watched the portal close.

"You didn't have to follow me," she sighed as she threw her weapons onto an elaborately designed red couch.

The whole room seemed familiar to Alec, the emptiness, the bar at the back of the room. It all slotted into place when a tall figure entered the dark room to stand next to the girl. Of course, of all places to be lead to, it was to Magnus Bane's apartment.

"What are you doing here? Magnus questioned,

"They followed me," the girl said innocently.

Magnus didn't even lay an eye on Alec, it was as if he was a ghost. He was wearing a black dressing gown and his hair was in its 'just woken up' hairstyle, Alec used to love putting his hands through his hair in the mornings. He had been yearning for Magnus ever since they broke up, spending time around Clary and Jace didn't help him try to move on.

"Seraphina, go to my room and stay there," Magnus demanded.

Seraphina nodded, crossed her arms and walked into Magnus's room.

"Who is she, Magnus?" Jace walked around the room,

"Why does it matter to you?"

"I don't know if you noticed, but if she is a Shadowhunter, she's a strange one," Jace picked up the boomerang blade and ran his finger over it,

"She's obviously a Shadowhunter," Clary pointed out,

"A Shadowhunter with no runes," Isabelle looked at Magnus.

Magnus shrugged and made his clueless face that Alec could always see right through.

"How could she create a portal when the only person to know of that rune is Clary?" Alec asked, partly hoping for Magnus to look at him.

Unfortunately, Magnus didn't look at him when he replied, "She's a smart girl. I'm surprised by the fact that she got there before you."

Alec fiddled with his arrow as he watched Jace walk around Magnus then back next to him. There was a moment when Alec wanted to tell Magnus how much he missed him and loved him, but then he realized how stupid he'd look and, with the way that Magnus was ignoring him, he'd get shot down like a deer.

"The Clave don't know of the rune that opens portals," Clary said,

"And it's obvious you're keeping some vital information from us," Jace tilted his head,

"There is nothing that you need to know. Now if you don't mind I have sleep to catch up on and there is a door that you should be leaving by over there," Magnus pointed to the door and it opened furiously.

Jace grinned as he walked past him and lead the way to the door. Clary and Isabelle followed him, but Alec stood facing Magnus. There was something about Magnus that seemed very guarded, as if he was protecting himself from an attack. He didn't look at Alec, instead he was looking in the distance and when Alec finally moved towards the door, his head moved to look at the floor. Before leaving, Alec turned around to look at Magnus. Nothing could hurt more than this moment Alec said to himself and he breathed in heavily.

"I miss you," he said almost like a whimper.

Magnus lifted his head up as if to beg for strength from any God that was above. He shook his head and gulped.

"Just go Alexander," he emotionlessly said as he turned away and sunk down into the couch as Alec left and closed the door.
