Hello! Seeing that For This Life is coming to its end, I've decided to post the first chapter for my next story. This is of course a friendship story with little romance in them (Clace, Malec and Sizzy). I hope you like it more and feel free to leave me your thoughts on it. They help a lot. :)

Summary-What is the difference between an angel and a demon? An angel that has fallen from its spot in heaven. On what cost? Their arrogance in love. When a demon's child decided to teach a shadowhunter of a lesson he'd learned from his early years with a man he called father, she would've never guessed things to turn back to her. Could the demon in her love like an angel? After all, that was the origin of every demon.

Chapter 1: The Calling

The air around the city park was thick with the stench of ichors as the sound of weapons clashing and arrows flying past; embedding each of the aim into its target. One after another, the foul forms of hideous demons fell and vanished as it touches the angel's blade; purifying whatever holy that was left in them and returning them back to hell where they would belong forever.

Amidst all of Lucifer's defeated soldiers stood a Nephilim; a fighter with angel blood running in his vein proudly enough to make him glow under the night sky. Partly it was because of his golden blonde flocks that seemed soft to touch and his seraph blades that were glowing angelic in his hands.

Nothing felt music to Jace as he twirls and dances among his opponents, taking them down with each graceful and trained step making the demons seemed like a bad partner for waltzing. Done with the one on his side he swung around, stretching his arms not too wide as the aim was merely close and grinned when he felt it slashed through, killing the demon.

As meticulous as Jace was with his moves, the pack of lizard-looking demons with gigantic claws and fangs black as the dark was almost too overwhelming for him alone. There, perched on a higher ground with his balanced under his command and swiftly letting go each arrow that never missed was Jace's parabatai. Alec was in his own world as he loaded his bow and struck deep into each demon.

Unlike Jace, none of the features on Alec's face spelled fun or joy. His eyebrows were creased together, showing his focus on the task and his hands, ever so steady and sure were showing veins as he gripped his weapon hard.

There weren't many left, only a few other hell's residents that Alec was sure could be handled alone by the figure that was the centre of attraction in that situation. His gaze somehow flickered to a distant on Jace's left. With the Farsighted rune still ink black on his forearm, Alec could make out a disfigured form lurking in the shadows. It was too huge to be a person and it seemed like an unsolid parallelogram as the one on the right was noticeably shorter than the one standing right beside it. They-as Alec assumed it wasn't only one- were standing quite a distance from the two Nephilim, as if on purpose of watching them finish off the demons. But what caught Alec's attention most was that the figure didn't appeared to be exactly where they were. The rigid outlined that formed them seemed to be blur, as if they were held back by a force field around them as their image slowly disintegrated.

Jace's shouting brought Alec back to his parabatai who was on the very last of that evening's task. He couldn't make out what the yelling had meant but in a split second, an arrow was already making its way towards the demon, killing it instantly.

Alec got up to his feet, his knees feeling a little bit cramped after holding onto the same position for the last forty minutes and he took a glance at his Strength rune. It had started to fade, leaving what would be a permanent scar on Alec's pale skin. He jumped to the ground and walked over to Jace.

"That was it? We didn't let any escaped?" Jace asked, sheathing his blades back into his weapons belt. When he brought his head up, Alec could see splattered of demons blood all over him; his gear, arms, shoes and face. His eyes however still shone with that same golden fire, mimicking the adrenaline rush that flows in him.

"No. We killed every last of them." Alec brought his hand up and ran it through his hair, feeling the dampness of sweat and the dust from the night air mingling all over making him felt dirty and needing a shower right that instant.

"You killed the last one. I could've taken care of it." Jace looked at him accusingly, making Alec felt like he'd taken the last piece of pizza on the table when there was someone else who hadn't had one.

"Then why did you yell at me? I thought you needed help." Alec glared at him.

"Didn't you hear what I said?" Jace took out his stele and handed it over to Alec. "What were you doing up there? Daydreaming?"

Alec let out a soft growl under his breath and got on to drawing an iratze for Jace. There were a few scratches and bruises around his left forearm and shoulder. His hand worked expertly around the injuries, entrusting the black-curled runes to heal his parabatai back to health.

"I thought I saw something in the trees." Alec looked around after he was done, nudging at a direction for Jace to look.

"More demons?" Jace asked; amusement and excitement coming back to his speech. His body poised in a ready stance and Alec rolled his eyes at him. No one could get excited over demons like Jace does. He made them look precious and cheap at the same time.

"I don't think so. They disappeared before you shouted at me."

At his own words, Alec stopped to think about the situation. Disappeared? If they were demons, why would they run away? A tapping sound brought Alec out of his musing and he realized that Jace was clicking his fingers at him and looking worried, eyes traveling to the rest part of his bodies, no doubt searching for injuries.

"Come on, Alec. You've got to tell me if you're hurt anywhere. I can't keep guessing like you always do." His voice was calm, always but his eyes, the ones that Alec had come to understand ten years ago wasn't. Why was it that Alec found things easier when looking into someone's eyes (except for Magnus's) than to hear what they really have to say?

"I'm fine, really. I was just thinking." He said honestly, learning from past mistakes that it wasn't the smartest thing to lie to Jace.

"Of Magnus?"

He groaned. "No. Why is it always him? Do you think of Clary all the time in your head even when you're killing things?"

Jace simply smirked at him and waved him off.

"I'm heading back to the Institute. Are you coming with me?" He asked, stretching his arms above his head and looking thoughtfully at his brother.

"Actually, no." Alec answered him, looking somewhat embarrassed with what he was about to say. "I'm going to Magnus's place."

"Oh." Jace had that devilish smile on him that made Alec thought of reaching out his hand and smacking him at the back of his head just to show he could do that. "Alright, I get it. I don't think of Clary all the time either. See you tomorrow, Alec."

Alec watched as his parabatai walked off, leaving him alone in the park not even waiting for his remark. He could only shake his head as he too began to walk away from their killing area and heading to Magnus's loft.

Typically, Alec would've noticed the two pair of eyes prowling in the dark as he was always the cautious one in their team. But that night was an exception as a warlock and a demon watched over the two Nephilim parting ways to different destinations, concealed by a magic-made wall that hid their existence from mundane eyes. It was by all mean their luck that night for even under the control of the angel's Sight rune, the Nephilims had failed to notice them.

"They parted ways, my Master." Said the demon-a very rare looking of translucent red covering his unicorn-like figure that hides the spike beneath his legs and in place of a beastly gorgeous spiralling horn was a deadly pointed ivory that could kill with its look.

"How many times must I tell you, Ifrit? Do call me by my name." Said an amused voice which belongs to a female warlock-hair white as milk and skin as violet as grapes. She stood right next to the demon.

"If you wish so, Morgana." The demon looked up at his summoner, not with fear but with admiration and devote. "What should we do now that they are separated? We can't get to both of them."

Morgana smiled at him kindly. "One will do."

A look of confusion spread on Ifrit's face before he asked,

"Which one?"

As Jace walked down the path heading back to the Institute, he couldn't restrained himself from glancing into a restaurant and his eyes caught a couple having a dinner late that night, laughing at each other's jokes looking so normal and peaceful. His mouth twisted a little bit with jealousy. One of the odds being a shadowhunter was that there would never be normal or peaceful. All the time, things-weird and irritating for Jace- would always come in between but now with Sebastian dead and the world was free of threat for a while, Jace could only think of one little girl with red hair as fierce as her determination, safely at home with her mother and her step-father.

He stopped dead in track, when he saw the guy in the restaurant got up from his chair and dropped down onto his knees facing the girl, revealing a small red box shaped like heart and when he opened it, Jace saw the girl's eyes swam with tears. Mundane, always so classic, he thought as he carried on walking. But deep down, Jace acknowledged the small affection that he too felt when he saw how sure and convinced the guy was with his act.

He thought to himself-too deeply to notice that he was being followed-how it would be like if he were to ask Clary for marriage? Could he do it? Was he ready enough to know, after all that had happened he could finally love without being destroyed?

"Well, well. Deep in thoughts I see, young Nephilim." The voice-cold and alluring and ruse-struck deep into Jace's attention as he brought his head up and look in front him to find nothing. Only then he remembered he had put on glamour on him. He said nothing, waiting for the owner of the voice that had caught him off guard to make her appearance. He was right when he saw a lady, white hair and purple skin that glows in the dark like fallen star came out from his right-a dark alley with barely lights shining the space.

"I'm flattered." She spoke, in the same tone. "Never before had a male watched over me like a predator. You make me feel young again."

Jace had indeed been staring but not for reasons she thought out loud but for something Jace couldn't put his finger on. She looks oddly…familiar.

"The fact that you do look like an exquisite walking grape, nothing else grabs my attention more." Jace replied.

"Rude and snarky, I like that." She laughed. It echoed throughout the air like a flute being played in the middle of a summer, relaxing yet there was still a tingling of unease that pokes the air-the heat.

"I find them useful with normal ladies." said Jace.

"And I am not normal why?" She asked, flinging one of her hands out and showing her long skinny fingers and clean nails.

"Obviously because of your colouring," Jace said after a moment of gesture for thinking, "it's not usual if you weren't a warlock."

The lady smiled at him, as if praising him for finally giving the right answer to her unspoken inquiry.

"I won't give you credit for that. Even that little girl-Valentine's daughter would've guessed faster than you did." Jace's face harden for a split second but that was enough for the warlock as she smiled even more, stretching her lips but never showing her teeth.

"Who are you? What do you want?" asked Jace, masking his nerves with years of training not to show fear.

"Please, do not mistake me for some lunatic like that brother of yours. I don't want anything from you." She voiced all the same before pointing behind him and saying,

"He does." Jace didn't turned quick enough. A hard blow to his head was all he felt as he embraced the darkness and fell to the earth.

"He could have struck me." Ifrit said, lowering his legs that he'd used to hit the shadowhunter, now sprawled on the ground between them.

"Oh really? Now I wouldn't have wanted that, would I?" Morgana said, narrowing her eyes to Ifrit who seemed to suddenly realize whom he was speaking to.

"My apologies, Morgana." He bowed his head as a sign of submissive but Morgana was already progressing towards the boy. She crawled on top him, directing one of her fingers that now grew a sharp nail before slicing his top gear across his chest, just wide enough to show a black rune on his collarbone.

"Now my dear Nephilim, let me show you how love can do much more harm than destroy. How angels on earth could fall even further than the ones in heaven. For this fall will be no end unless an equal blood of measure was to be spill in your name." She whispered softly to the shadowhunter's ear-so melodious and yet grieve-filled rhythm sparked the atmosphere before she touches the rune on his collarbone and enchanted her gift upon him.

Magnus felt it more than heard the knocks on his door. He knew Alec had left his key on the kitchen's table yesterday evening in his rush and would be counting for him to open the door. He glanced at the clock on the wall, his cat-like eyes shining in mischief when he noticed that Alec was rather early that evening.

"Hello, sweet cheeks." Magnus greeted his shadowhunter as he opened the door. He was unperturbed with the sight that welcomed him-ichors and dirt covering what was beautiful underneath that lethal-looking warrior and no scratch of blood that would need his attention that night.

"Hi, Magnus." Was all that came out from Alec's mouth as he was dragged inside the warm loft, hearing the sound of lock clicking and then his lips was captured with another. That took his breath away (Magnus always does) but he responded nonetheless. An impressive amount of minutes of hands lost in the depth of black hair and fingers raking up on the trail of spine and in between shoulder blades, they pulled apart, both breathless and flushed.

"Magnus, that was-"Alec never finished his sentence. Magnus was struck as he watched Alec's blue eyes rolled back into his head and he fell limp before embraced by Magnus's arms that caught him in time.

"Alec? Alec, can you hear me?" He asked, shaking the shadowhunter by his shoulder as they fell to the floor. Worried etched the lines between Magnus's eyebrows as he got up and carried Alec onto the bed that they had shared for the past months. He laid him down gently and got on to work as he pulled Alec's gear off him, belatedly noticing that one of the runes on Alec's forearm was glowing a purple bright.

That caught Magnus's attention as he threw the dirty clothes onto the ground before conjuring up Alec's usual night wear-a plain blue shirt and a pair of black pants on the bed. The glow was almost blinding when it suddenly receded and the rune was once again black.

"Magnus? What happened?" Alec's voice shocked Magnus even more. The boy was fully awake and on his elbow, peering up at Magnus. What was happening?

"You fainted on me." When he observed closer, he could tell that nothing was wrong with Alec. No sign of pain or distress or whatever that goes along the line. Whatever it was, it had come from the glowing rune.

"I did?" Alec brought his fingers up and touched his lips. "But I feel fine. You even undressed me." Alec stated in delay.

"You look fine but your parabatai rune was glowing. I'm gonna call and check on Jace for you." Magnus said, although he felt strange on the thought of giving a call to Jace. "Why don't you get clean up?"

Magnus had anticipated a usual answer-okay or maybe alright from Alec-but what came out from the shadowhunter's mouth, a simple one word made Magnus freeze all over and stopped dead in his track.

Alec had asked him, with confusion all over his face,

"Who?"

And that's it for the first chapter. Please let me know what you think so that I can make up mind whether to continue this or not. Thanks for reading! :)
