I do not own Harry Potter or the Mortal Instruments series; they belong to J. K. Rowling and Cassandra Clare respectfully.

WARNING: Will contain SLASH, HET, mentions of MPREG, violence and swearing. This is also AU from Harry Potter series. Non-human Harry. Not beta'd.

Pairings: Harry/Alec, Jace/Clary, Simon/Isabelle, Luke/Jocelyn

SET: After City of Glass, so what happens after never happened. Also, Alec and Magnus never got together (I love that pairing though).


Magnus' POV

Blue sparks danced along Magnus' fingertips. His other hand cradled his chin, elbow on the glass table. Around him the voices of the young shadowhunters rose and fell as they argued over Alec, the faeries, and a war which Magnus hoped might never come.

"We should never have let him go," Isabelle stated as she glared at Jace angrily.

"And what do you suggest? That we go back down there and say 'sorry, our mistake, we've decided to forgo the wedding and go straight to war'? Because that's what going to happen!" Jace argued. "Alec knows what he's doing. He's the most level-headed of us. If anything were to happen to him I would feel it."

"And if we're too late? Then what, genius?"

"Look, we've been over this," Clary stepped in, hands held up in a defensive gesture. "The Clave are not taking the deaths of the faeries seriously. The only way to calm them was to agree for Alec to marry Hadrian. It gives us time to find out what they're planning and counter it with our own plan."

"The Clave would never have agreed to this and the queen knows that," Jace added, "Whatever it is she's planning, it has something to do with us. Otherwise she would have her representative suggest it at one of the meetings or not at all."

"But its Alec," Isabelle said. "If anything happens to him…"

"It won't," Simon, who had been sitting by Magnus, spoke up. With his pale, sickly looking skin and the dark circles under his eyes, Simon looked every inch like the gaunt and tired vampire that he was. "The queen wants us for something. Suggesting marriage? She aims to strike at us using her grandson. She sees us as the biggest threat. Jace and Clary took out Valentine! Where were they when the demons came? With the shadowhunter numbers down, you guys are easy pickings." Simon surmised. "Though, not easy enough it would seem."

"So what, Hadrian is her little spy?" Isabelle looked about ready to storm out and go back to the faerie world.

"No," Magnus looked over at her. "Hadrian is anything but. She is his only family, well," Magnus shrugged, "immediate family at any rate, but to Hadrian blood doesn't make family. I know him; I know how his heart works. If push comes to shove he will do what he thinks is right." Which, Magnus thought, would hopefully be in their favour.

"And is that siding with us?" Jace demanded. "He would betray his own kind, his own family, for strangers?"

Magnus stood. "You forget, Alec will soon be his family, and by extension, you. The queen may treasure Hadrian but she will sacrifice him to further her cause. Hadrian knows this, and he will pay her back in kind."

"How well do you know him?" Jace asked.

"Intimately," Magnus grinned, fondly recalling the many rendezvous the two had shared. Hadrian still needed to have a constant escort to shadow him whenever he wished to visit England. "We were lovers once, a long time ago. We stayed in touch."

"I bet you did," said Jace.

"So he's on our side then?" Clary asked for clarification.

"I believe so, yes," Magnus' cat-like eyes narrowed on Isabelle when she made a noise of disbelief. "Hadrian is dear to me, you will not harm him."

"Sounds like you're still in love with the guy." Jace paced, too wound up to stand still.

"I love him, but I'm not in love with him," Magnus told them. "Not anymore at least."

That was the one thing that worried him. Hadrian could make people love him and then he could destroy them. It wasn't always his fault either.

"Well that's great," Isabelle ignored Simon's attempt to calm her down, little though the action was. "But I don't trust him, even," Isabelle raised her voice when Clary tried to interject, "if Magnus says so. He is still a faerie and the grandson of the queen as well. He will have his own agenda."

"Of course he will," Magnus laughed. "Everything Harry does is to benefit him in some way."

"Its Harry now, is it?" Jace waggled his brows. "Remember he's a taken man, or faerie, now."

"That's a point," Clary looked up at Jace, "Didn't he say that he was with Raphael?"

"The vampire?" Simon yelped. "My- you know," he made a wild motion at his neck.

"Your sire? Yes," Jace looked irritated, "As if we haven't dealt with your lot enough."

"Jace!" Clary scolded while Simon glared at him.

"What?" Jace gave her such an innocent look that the girl couldn't help the smile that appeared on her face.

"If you two would stop flirting for a second," Isabelle bit out, "can we go back to Alec?"

"There's nothing that we can do," Magnus said with exasperation, "Both Alec and Hadrian have accepted the marriage. They are to be husband and husband in two days. Congratulations."

Isabelle glowered at the wall. Magnus rolled his eyes, reminding himself that he was dealing with teenagers.

"Alec is an adult," he added, "let him do this."

Jace clenched his jaw. "As much as I hate to say this, but Magnus is right. We've been over this before. We accepted Alec's decision then, and we need to trust him."

"So we wait?" Isabelle shook her head, her black hair flying around her face. "That's it?"

"That's it," Magnus said. The rest of the group looked at one another. None of them liked the plant but it was the only thing they could do.


Hadrian's POV

"My queen," Hadrian knelt at his grandmother's feet, "you summoned me?"

"My little one," the queen smiled her shark-like smile as she stood before him in a foam blue dress that did little to hide her body. "Tell me, has the shadowhunter settled in?"

"He has," Hadrian got to his feet. "He's resting at the moment. I believe that the days' events have tired him."

"Indeed," her crystal eyes regarded the young faerie sharply. "And your plans for him?"

"I will marry him," Hadrian told her. "And I will do what you wish. I also know that you want me to infiltrate his little group, find out what they know, and if they have any clue as to what you may have planned for them."

"Which is?"

"Valentine was an enemy true," Hadrian spoke carefully, "but the shadowhunters did little to stop him from hurting us. It is also the shadowhunters that are doing nothing about the deaths of our kin, apart from maybe encouraging it. They are becoming arrogant. They are restricting us, treating us as if we were already the enemy when in fact that is yet to be the case."

"Do you believe that the shadowhunters are our enemies?"

Hadrian hesitated. "Those who stand in our way, those who don't lift a finger to help us, and those who will soon raise their swords against us, are the enemy. They will fall at our feet. I will see their blood on my blade and their bodies under my foot. The shadowhunters will fall and we shall rise."

The queen tilted her head. "Such a speech, I have taught you well."

Hadrian bowed his head. "The shadowhunters are our enemies." Some of them at least.

"Yes, they are," The queen circled her grandson. "Your voice rings truth." She reached up and ran a finger down his cheek before cupping his face. "I remember when we turned you as it were yesterday. The spell your mother placed on you, to keep you human, broken and your true self revealed. Do you still resent me for that?"

Hadrian closed his eyes and leaned into his queen's touch. "No not anymore. You have given me a gift. Time has taken away such petty emotions like resentment. I still mourn my James but his blood still flows today."

"He would have made a good faerie, a good warrior." The queen said softly. "But enough about the past, let us talk of now."

"Yes, grandmother," Hadrian replied dutifully.

"You are to gain the trust of the shadowhunters, though that will not be hard with the history you share with Magnus Bane." The queen stared hard into Hadrian's eyes, looking for the faintest hint of deceit. "You will tell me what you hear. Then, when the time is right, you will strike. Love, my little one, makes everyone weak. Work on your shadowhunter, make him fall in love with you, and then destroy him with it." Hadrian didn't even blink. "You make people fall in love with you so easily. I want you to break him, like you did for me before."

"Do you want me to kill him as well?"

"No," the queen shook her head, "At least, not yet. I so enjoy seeing what loving you do to people. Even now, when I hear whispers, knowing that the infamous Malcolm Fade is now little more than a child in a man's body brings me such delight."

It took every ounce of control that Hadrian had to not even twitch at the mention of his ex-lover. White-haired and purple-eyed, the warlock had instantly caught Hadrian's interest. Unfortunately under both the words of a long-dead friend and the queen herself, Hadrian had driven Malcolm into an act that had cost him his mind. He had broken him.

Hadrian's ears picked up the faint rustling of the struggling dragonflies and the faint swish of the queen's dress as she moved, waiting for him to speak.

"I did it for you," Hadrian finally replied.

"You have given me your loyalty," the queen's eyes glittered and her voice became soft. "And one day child, I shall repay you for it."


Alec's POV

Alec was no fool. He was the most sensible shadowhunter out of his friends. He thought through his strategies and acted in the interests of saving his family. This was no exception. He was the eldest, the one who had no love interest (as much as it burned him to know that his little sister was involved with a vampire of all things), and the one who could keep a cool head under pressure.

Alec also knew that just as he and his friends had a motive to go through with this wedding, so did the queen and her grandson. A faint blush dusted Alec's cheeks as the face of his new betrothed flashed through his mind. The faerie certainly was handsome, and charming at that. He was not like the rest of his kind. But, Alec reminded himself, the faerie was not on their side. His loyalties, no matter how much Magnus claimed otherwise, was to the queen. Until proven otherwise.

His fingers curled around the handle of his stele, the cold metal bringing Alec some comfort as he investigated the chamber he had been left in.

He didn't want to think about the consequences of his actions. What scared Alec, and yes he could admit that, the most was if and when his father found out about it. Though, Alec mused as he picked up the photo frame of the child on Hadrian's desk, he didn't have to say that he was gay. It was all part of a plot to uncover the queen's true intentions. Robert didn't need to know more than that.

The rustle of the curtain that was used as Hadrian's door alerted Alec to his betrothed return. The faerie had been gone for a while, off to speak to the queen and give her his report no doubt. He gently placed the frame back on the table and turned.

"Curious little thing, aren't you?" Hadrian smiled, he did that a lot Alec noted, nothing like the other faeries of the court who were all straight mouthed and emotionless; unless they were up to one of their tricks.

"There isn't much for me to do," Alec defended.

"My apologies," Hadrian walked over to him and stared down at the child in the photo. "I spend little time down here myself so there is not much in the ways of self-entertainment."

Alec looked between Hadrian and the little boy.

"Is- I mean, who is that?" Alec asked.

Hadrian turned his sharp eyes on Alec, cold and serious. "I am two-hundred and twenty seven years old, Alexander. I have seen many things, done many things, and lost so much." He looked so stern then, and sad. "It is sometimes best to leave things in the past; where they belong."

Hadrian moved away then, back to Alec, and strode over to the sofa.

"I will lie here tonight, you may take the bed." Hadrian ordered. "I sleep little as it is."

Even though Alec was too wired to sleep, he didn't argue. The way Hadrian was prowling around to get ready for bed, and here Alec averted his eyes and blood rushed to his cheeks as Hadrian stripped to change, made the hairs on his arms rise and warning bells go off at the back of his mind. Don't push him, his mind whispered, don't test his patience.

Hadrian may seem kind in comparison to his kin but he was still one of them while Alec was an outsider, an enemy almost. He had taken advantage of Hadrian's openness earlier with the story of his mother, and had foolishly expected Hadrian to tell more.

Alec's gaze wandered wearily back to Hadrian, noticing that he was already lying -and why did that make his stomach twist?- on his stomach, his own eyes locked on Alec.

"Are you going to bed or not?" Hadrian asked, "I promise I won't look."

Alec's face burned and Hadrian grinned and closed his eyes.


Second chapter done. Since I'm really winging this story, I don't really have a solid plan on what's going to happen next. Isn't that just exciting? Lord knows what going to happen. Hoped you like it.
