Heyyyyyy!!! This is a prompt I JUST HAVE BEEN WANTING TO READ for the longest time!! A fic based on Angel with a shotgun -CAB

BAMF Alec is my jam!! x

ARGH I LOVE THIS SOOOOOOONG. MY SPN ROOTS ARE COMING FOR ME I CAN FEEL IT. UGH IT'S SO GOOD THOUGH. Okay, time to go let's GO.

Highly recommend listening to Angel With A Shotgun while reading this fic, cause uh, yep.

In a world where the Alliance Rune doesn't exist, and Asmodeus brings Magnus to Edom...

~!~

The instant that Magnus sealed the rift to Edom above Alicante, Alec had one mission, and one mission only.

He was not going to leave Magnus to the tender mercies of Asmodeus, or Lilith, or the hell armies that were there, whether or not he was a Prince of the realm. Alec was not going to leave him alone.

The aftermath of Alicante would take years to properly clean and in another world, in another time, Alec would have been involved in the rebuilding from the ground up.

In the world where Magnus was trapped, by himself, in a demon realm, to keep all of them safe? There was only one place that he would go, and whether or not he came back didn't matter. He was going to be with Magnus and that was all that mattered. No one was going to stop him. Not Jace, not Izzy, not anyone.

Jace and Izzy, both of them knew, both of them understood, and Alec loved them fiercely for it when they said they would be coming with him. They would not let him go alone, and he loved them for that even more. He would have gone alone to fight the war if that's what he needed to do, he would do it in a second.

It took more than a week to find away into Edom, and if rumors were correct, it would sap them of all their strength while they were down there. Small charms could protect them for a time, but if they were down there too long… well.

Alec closed his eyes and breathed through the pain of that revelation before he re-opened them, his eyes fierce and furious. "Then we bring him back." It was a simple statement, and with Catarina on standby to create the portal to send them to Edom, despite her reservations, there truly was only one answer. They were going to bring him back, or he was going to die trying.

Stalking to the armory, Alec threw the doors open, shadowhunters scattering in front of him. If they were going to fight a war in Edom, then they were going in prepared. He pulled out the stele and swiped at the hidden door in the back of the room, opening the weapons cache that the Clave liked to pretend didn't exist.

Jace's eyes widened. "What the hell is that?"

Alec reached out and pulled down a spare blade, and then the shotgun sitting on the stand, cocking it in an easy motion, turning to look at him with a raised eyebrow. "Do you really think that with a Weapons Master like Isabelle, the most advanced weaponry we had comes from the Bronze ages? Suit up, Jace."

Isabelle laughed in delight and dove into the cache. "We get to play with all the fun toys now!" She quickly moved to one side wall and began sliding the knives into her hair, into sheathes on her arms and picked up another of the guns and several ammunition packs. "It took me a long time to figure out how to integrate standard mundane ammunition with adamas, it's very explosive. But after-"

"After what happened with the dragondae demons, and how someone who can fly can devastate Institutes simply by taking out their only long-range weapon wielders, I gave Izzy the command to find another way. Mundanes had an answer, it was time that we looked at the same," Alec said, lifting a belt of cartridges over his head. "We are going to war, Jace, and I don't expect to be coming back." His voice was matter of fact and simple.

"You're going to come back," Jace said, his voice firm. "We're not going to leave you down there."

"Then we bring Magnus back," Alec shot back, his eyes blazing. "If it were Clary there, you would do anything and everything to bring her back, including staying there with her, wouldn't you?"

Clary stepped in beside them and ignored their surprised looks. "Of course he would, and I would do the same for all three of you. Now give me those pistols. Luke taught me to shoot years ago." She quickly holstered them and shot Alec a quick smile. "Magnus is my friend too, we're not leaving him to Edom."

Alec swallowed, giving her a quick nod before he turned away and grabbed a handful of blades, sliding them into the holsters on his thighs, before grabbing his bow and quiver, last of all. He tightened his hand around it and breathed slowly, in and out. They were going to rescue Magnus, they were going to find him, and they weren't going to stop.

Clary reached out and gently touched Alec's arm, meeting his eyes when they jumped to hers, smiling at him. "We're going to get him back, Alec."

"Damn right we are," Alec snarled, and stalked out of the cache, closing it behind all of them before turning to Catatrina and her wide eyes. He led the way to the portal room that they were using and ensured that Underhill had orders in the case of their return, and in case they did not. Once that was complete, it was a matter of stepping into the portal once it was on fire.

It burned.

Fire in his lungs, in his throat, in every inch of him, consuming him, until abruptly, all at once, it was gone. Alec stood up and looked around the red lit world, closing his eyes to try to breathe in deep, only to end up coughing. He could already feel how tired he was under the weight of the power in the realm. This is what it was going to be like to fight here. He looked around him and found the other three and gave them a nod, turning toward the castle that he could see in the difference.

"Let's go," he ordered, tightening his hand on his bow, drawing arrows. "Magnus is waiting for us and I have no doubt that we're going to fight an army on the way there."

~!~!~

Magnus snarled, not for the first time, the ring on his hand the only thing that could draw his attention as he paced across his room, his power snapping, bright and vibrant. Upstairs, his father was holding court with Lilith, bartering her safe passage through the rift that he would need to open in order to take her vengeance. Nevermind that he knew they would also make sure she disposed of what Asmodeus considered his little 'problem' with the Nephilim.

There was so little that he could do with his father and Lilith both standing against him in the realm, but what else was he supposed to do? How was he supposed to keep Alexander and his family safe after closing the rift behind him, locking himself into-

A roar of anger from his father had his head snapping up and Magnus turned and threw open the door to his room, striding up the stairs. To hell with either of them if they wanted to curse him for invading their meeting.

Magnus got to the top of the stairs, where the throne was and froze. Neither Lilith or his father were there, and there were no signs of a fight. He spun, looking around frantically when the scream of demons overhead, heading to the west made him turn in that direction. A cloud of demons was descending toward the ground. Reaching out with his power, Magnus frowned, trying to feel out what it was that was there, what would have caused the both of them to-

Nephilim.

Edom's voice was soft, a siren call of alert.

Nephilim had invaded.

More were coming by the minute.

Pouring into the realm.

Magnus' eyes slammed open as one of the signatures, faint, considering the amount of angelic power being drawn into the realm, was one that he recognized better than any other. With a swirl of violent blue magic, Magnus portaled himself to the only person that could own the signature.

Landing in the field, Magnus ducked under two swings of a seraph blade and heard Alec's thunderous voice echo across the army of Nephilim to stop. Magnus stared, wide-eyed, at the Nephilim who were pouring through the open portal behind them, even though others were engaged in fighting the demons around them.

Though he could feel Alec's signature, he couldn't see him and looked around wildly. The sound of guns going off had him ducking on instinct and it wasn't until he saw a demon explode into ichor and the sound of a shotgun reloading that Magnus was able to refocus on what was happening around him.

There Alec stood, sliding shells into the shotgun in his hands before raising it and shooting the next demon that dove at them, followed by another, then another. The sight of his empty quiver explained the mundane weapon, but not their effectiveness. The sound of another shot had Magnus spinning around, and there was Jace, and Clary, Clary of all people also wielding-

"Magnus!" Alec shouted, trying to move through the crowd toward him. He fired at another demon with a snarl and cut one more down with a seraph blade, finally making it to Magnus' side, breathing hard.

Even though he had been staring, the sight of Alec didn't seem real. "Alexander?" Magnus reached out to grab Alec, staring at him in shock, certain that his hands were betraying him, but it was real. Alec's eyes were burning white with angelic energy and Magnus could feel it pouring off of him in waves. "Alec, what-"

"I am not LEAVING you," Alec snarled, twisting them away from a diving demon so Jace could get an open shot to take it down. "We are bringing you back!"

"Did," Magnus looked around all of the Nephilim, all of those he recognized from the New York Institute and felt his eyes threaten to burn. "You all came for me?"

"Of course we did, now can you help?" Jace snapped. "You two can have your romantic reuinion as soon as we fight off the rest of them!" Turning to the fresh group who had come through the portal, he ordered them to support the other archers on the left side.

Magnus yanked Alec down into a desperate kiss, the one thing that he should have done before taking the portal to Edom and stared at him. "Give me a minute," he ordered, nearly laughing when Clary, Isabelle and several other shadowhunters moved to cover him from the waves of demons coming for them.

Magnus tilted his head back to look up at the sun. He could feel his father, Lilith, both of them waiting to see what he would do, how he would fight back against them, because right now, they were toying with the Nephilim. The shadowhunters that were slowly going to die in this realm if he didn't do something to help them and fight them. He pushed his feet deeper into the ground and reached out for the faint voices of Edom that he could still hear whispering in the back of his mind.

"Answer me," he whispered, his voice carrying on the winds. "I have fought for you, I have healed you, I have lived for you, and I was borne of you. I do not bring you to war, I do not seek to subdue you, I do nothing but ask for you to answer." Wind started to whip around him and Magnus felt it tug at his coat, at his magic, dust gathering in the air around him.

"Answer me," Magnus demanded, his magic growing in volume as he breathed in deep, the red-hot burning earth suddenly alive in his hands, the pulse of it growing louder and louder by the second. It was easy to feel now, the breath of every demon they were fighting, the violent dots of power that were his father and Lilith ahead of them, commanding the demons for them. Edom reached out for him, away from the toxic spread of power from his father and Magnus smirked, keeping his head tilted up to her sun.

Another loud, violent snap of magic echoed across the field and with a thunderclap, blue magic exploded out of Magnus, washing over the Nephilim, clearing the influence of Edom from them. His eyes blazed as he heard the roar of fury from his father and, behind him, Clary, somehow, explaining what he had done, and how they needed to get ready to charge.

Magnus took a step forward, through the ranks of shadowhunters protecting him, up to Alec, standing at the very front of the battle, of the approaching hoards of demons, Jace at his side. Magnus took another slow inhale, and took another step. Then another. The realm beneath his feet began to tremble and roar, and the demons that were attacking took a step back from him. Magnus looked at them, his magic billowing around him in a violent, electric blue cloud, ready to strike in a moment.

"Answer me!" Magnus screamed, and the answering roar of the realm shook the sky. He charged forward, his eyes on his father, destroying the charging demons with a wave of his arm, blue lightning cackling across the sky to strike at them again and again, scarring the landscape that quaked, pouring power into him, even as he spent more and more of it with every single motion of it.

Beside him, Magnus could feel the one presence that had never feared him, that stayed, step by step, despite the magical power pouring off of him in waves, and just beyond him, those that his lover called family. Magnus flooded them all with the power of his realm, the realm that would answer to him, that would become his through the neglect of his father and Lilith and they would have no say otherwise in the matter.

The demons in front of them trembled and Magnus stared at them, his arms curved and ready for the threat and attack they would attempt before breathing out, the weight of the realm behind him as he spoke.

"I have led you before for centuries. We have destroyed realm after realm together. Now you dare to raise arms against me. You know my name, you know the name I have chosen for myself. Do you stand in front of me?" Screams of the demons as they ignored the shouted order of Asmodeus behind them, as they shared looks.

When they began to charge forward, despite his threat, Magnus smirked and licked his lips. "Then war it is," he promised.

"Together," Alec promised, sharing a look with Magnus, cocking the shotgun in his hand again with a grin. "How do you think Lilith will like a shot of Adamas to the face?"

Magnus' answering grin was bright and feral as he turned. "I can't wait to find out."

"We'll punch a hole," Jace shouted, waving the Nephilim behind him through. "The portal is closed for now, leave the demons to us, you go tackle Lilith and Asmodeus."

Before, Magnus would have been afraid to face them, but now, with Alec standing beside him, it was easy to let the Nephilim ranks charge past them into the approaching demons before breaking through the line, headed for where Lilith and Asmodeus were sitting together, the both of them watching the battle.

Lilith laughed at the sight of them, her head falling back as she settled into her conjured chair. "Well, well, if it isn't the little princeling. Finally done moping in your room? Come here to play with the rest of us?"

Magnus snarled at her, his magic reacting in a bright blue flare of anger.

Alec stared her down and with a quick glance at Magnus, didn't bother to stop in front of them. He knew Magnus would have his back. He approached her, felt her eyes on him, curious and uninterested. She was going to regret that. Standing in front of her chair, Alec spun the shotgun in his hands and fired it at the demon standing by her side, watching it dissolve in a shouted scream.

In an instant, Lilith was out of the throne, her eyes on fire and Alec spun the gun again, pointing it directly at her. "Enjoy," he snarled, firing it point-blank, watching as the adamas and salt mixture sank into her skin and it began melting. A blue lightning bolt arched past him and destroyed the demon on his other side as Lilith stumbled backwards. Alec barely spared an instant to look at Asmodeus, cocking the gun again before firing it at Lilith another time, sending her stumbling.

"You'll pay for that, you little nephilim whore!" Lilith screamed, her fingers elongating into claws as she dove for him.

Alec dropped the shotgun and drew both of his seraph blades, catching her claws before he kicked her back shoving her to the ground, only to dive under a blast of magic from her.

Magnus kept his attention on his father. His magic would take care of Alexander as much as it was able, but the fight for the realm, with the two of them tearing Edom apart between them, was about to take place, and the rest of the battle began to fade away.

"You never learn, do you?" Asmodeus asked, shaking his head. "I have given you far too many chances, Magnus. I thought you understood, and coming back here, coming home you would see that I was right."

"You are wrong," Magnus said, his voice reverberating with power, even as he stared his father down. "You are wrong about everything, about Alexander, and especially about me."

Asmodeus narrowed his eyes. "You know that I could kill you all in an instant."

Magnus laughed, low and harsh, summoning a black blade to his fingertips, one gifted to him by Asmodeus centuries ago. "You could try, after, but you would fail."

"We'll see about that, won't we?" Asmodeus purred, diving forward, summoning a blade of his own.

Alec could feel the ever-increasing worry from Jace through the parabatai bond, but it clearly wasn't worry for themselves. From the brief glances he could see, the shadowhunters were holding their own against the demons coming at them, but his and Magnus' fight against Lilith and Asmodeus was going on too long. He didn't duck fast enough under a slash from Lilith and her claws caught his shoulder, making him shout in pain.

He felt Jace's answering shout, and Clary's echo, but it was Magnus Alec FELT, rather than heard react, and before Alec could tell him to worry about his own fight, Asmodeus had charged forward to wrap a hand around Magnus' throat. Alec froze, his heart pounding wildly. When Asmodeus' eyes met his, Alec's heart constricted as he watched Asmodeus start to SQUEEZE.

Magnus kicked out at his father, but his magic was sputtering under the suffocation of his own magic and he tore at the hand around his throat, trying to warn Alec to retreat, to get back, their eyes meeting right before he watched Alec close his eyes. "Alec, no, no!"

"Jace!" Alec screamed the word, tossing his blade into the air, spinning away from Lilith, before racing for Asmodeus and Magnus. Magnus' magic was surging around him in the protective cloud that had been keeping him safe for what felt like hours, and Alec pushed forward, batting aside the defense that Asmodeus lifted up and tackled the demon. He grabbed the spare blade in his belt, twisting it before slamming it into Asmodeus' heart. Alec pulled the blade out and drove it in again and again, tearing it through ichor and demon blood that poured over his arms, burning every inch of his skin.

There was a scream, and then a thunderous echo in the distance. The magic that had been tearing at him started to glow brighter and Alec plunged the knife into Asmodeus once more, staring at wide and shocked golden eyes before snarling. "You will never hurt him again." He twisted the knife and closed his eyes, screaming as the power bleeding off of Asmodeus started to rip into him.

Magnus scrambled to his feet, trying to race for Alec, to warn him that his adamas might wound Asmodeus, but it wouldn't be enough to kill him, wouldn't be enough to end him- when there was a scream so loud it seemed to rend the realm in two. Staring in shock, Magnus watched a tornado of power erupt from where his father had been, before he went still, everything going still around him.

He had barely an instant to see Alec's wide and terrified eyes before they were clenched shut as Alec screamed as Edom's power began to flood into him. Alec had killed the ruler, and now the power would come to them both. Magnus managed to get to his feet, watching as Alexander's runes started to bleed, the angelic power in him completely at war with the demonic power flooding into him. The two types of power were going to tear him apart.

"Alec!" Magnus shouted, finally managing to kneel in front of him, grabbing at his face, and wiping the blood away from the corners of his eyes. "Alec look at me!"

Magnus shook Alec again, and when dazed and bloodshot eyes looked at him, he pressed their foreheads together, his chest heaving desperately. Lilith was screaming in the background but someone was fighting her, someone was keeping her away from them. He pressed his hands tighter to Alec's cheeks and heaved in a breath, staring at Alec.

"You have to let it in, Alexander," Magnus told him, using magic to deafen the roar around them, so Alec could hear him. "You have to let it in, or it's going to kill you, it's going to rip you apart and kill the angelic parts of you."

"Magnus," Alec whispered. "I…"

"I know," Magnus said, his voice edging into a sob as he watched Alec's eyes go hazy with pain. There was so much blood and he could feel Alec starting to sway. "You have to give it up, you have to, or the demonic power is going to kill you, Alec, I'm sorry, I'm sorry, I can't stop it, I'm sorry."

Magnus trembled as he felt Alec's arm come around his waist and pressed their foreheads tighter together. The tornado of power pouring into Alec was only getting stronger by the second and Magnus didn't let go. Alec was an empty cup that it was attempting to feel and he could already hear the pulse of Edom reaching out to the both of them, naming them ruler together, and he sobbed, holding on tighter. It was up to Alec now, and whatever choice he made. Die as a nephilim or live as…

Alec closed his eyes and leaned into Magnus.

There never was a choice.

He was going to say, no matter what. No matter what.

Giving up his faith, giving up what he was?

It was easier than he expected.

The second his runes were gone, burned away by the demonic power, the last thread remaining - the bond between he and Jace snapping - before Alec felt Magnus' magic grab it and pull it back right where it belonged, Alec sucked in a frantic breath as everything seemed to go quiet.

The tornado of power was rapidly fading, and while it wasn't as strong as it once was, Alec could feel Jace worried about him, that worry overpowering everything else. He blinked his eyes open slowly and stared up at the sun ahead of them. The air felt normal, no longer hot and heavy, and beneath him, he could feel the heartbeat of the realm, and how his own heartbeat echoed it.

"Alexander? Alec, can you look at me?"

Magnus' demand was easy and Alec slowly tilted his head back down, staring at Magnus, at the blood streaked on his hands, along with soot and sweat, clearly exhausted and bruised, his body shaking. Alec reached out to touch him, to rub a finger along his cheek, cupping his face slowly, carefully.

"Alec," Magnus sobbed in relief. "Fuck, Alec, you…"

Alec swallowed, his mouth dry and blinked a few times, the pounding his ears almost too loud to hear Magnus as he nodded. He looked around, looked at the other shadowhunters that had followed him, against orders, into Edom, and at Jace, Isabelle, and Clary, all of them standing and grinning at him. He leaned into Magnus.

"I'm okay," Alec barely managed. "I'm… fuck I'm okay. What happened?"

Magnus tightened his arms around him, squeezing him tight. "Lilith and my father are gone." He swallowed and looked at all of the New York Institute shadowhunters, daring them to say a word before he turned back to Alec. "You ah. You evoked a hierarchy claim on Edom by killing Asmodeus here. Edom, well. She's half yours now."

Alec blinked and stared at Magnus. "It's what?"

Magnus wanted to laugh, but the sight of golden slitted eyes on Alec just made him smile and he leaned in for a desperate kiss. "You, you had to give up being a Nephilim, or the magic was going to kill you. But you're now, well. A Prince of Hell in your own right."

Alec frowned, squinting at Magnus before he heard Clary and Izzy start to laugh on the other side of him. He looked over Magnus' shoulder at them and scowled. "What's so funny?"

"You decided to come to Edom to rescue Magnus, you head down here with no plan other than fight, you kill the king of the demon realm, which is the second Greater Demon you have killed by the way," Isabelle said, ticking off her fingers. "And somehow you also became a Prince of Hell. I don't envy you that paperwork, hermano."

Alec's lips curved into a smirk. "Well," he said with a cough. "If I'm no longer one of Raziel's children, Izzy, sounds like it's actually YOUR paperwork."

Isabelle blanched, her eyes widening.

Alec grinned and turned his attention back to Magnus, pressing their foreheads again. "About that dramatic and romantic reuinion?" he asked, hopeful.

Magnus shook his head, a relieved breath escaping him. "You came for me," he whispered. "You came for me, Alexander."

"Of course I did," Alec breathed. "I'm, I love you. I'm always going to rescue you." He wrapped an arm around Magnus and pulled him into a soft kiss. "I love you, and I am going to marry you. You're stuck with me FOREVER," he emphasized.

Magnus' breath caught in his chest and tears started to gather on his lashes as he held onto Alec even tighter. "That, that sounds amazing," he admitted, his fingers tangled in Alec's hair. "Know what sounds even better?"

Alec laughed, low and hoarse. "Celebrating our engagement?"

Magnus grinned. "That, and…" he lifted Alec's fingers slowly, and with a small nudge of his own magic, watched as silver-white magic flared to life in Alec's palm. "Watching you learn to use your magic."

Alec's breath caught and he dropped his hand, yanking Magnus into another kiss. Learning his magic could wait, they had forever. It could wait.
