Work Text:
The soft light of morning filtered in through the high windows of the loft, throwing long shadows across velvet cushions and polished wooden floors. The scent of sandalwood and something faintly sweet, cinnamon, maybe, hung in the air like a memory. Somewhere nearby, windchimes tinkled faintly in the summer breeze.
Alec Lightwood blinked.
His head was pounding, his ribs ached, and there was a sharp pull in his thigh when he tried to move. But it wasn’t the pain that caught him off guard.
It was the bed.
Silk sheets. A four-poster frame. Charms glimmering faintly in the carvings.
Definitely not the Institute infirmary.
He turned his head and winced as pain lanced through his side, but managed to take in the rest of the room. Warm golds and purples. Strange, beautiful plants curled along the windows. A familiar blue couch across from the bed, and on it…
Magnus.
The warlock was sitting with one leg crossed elegantly over the other, a book in his hands, though his eyes were not on the page. They were on Alec.
“You’re awake,” Magnus said softly, his voice gentler than Alec had ever heard it.
Alec tried to sit up. Magnus was at his side in an instant, pressing a warm hand to his shoulder.
“Don’t,” he said. “You’re still healing. I’ve done what I could, but even magic has limits.”
Alec sank back into the pillows, grimacing. “You brought me here?”
Magnus hesitated. “You nearly died, Alexander. There was no time to wait for Institute medics. You passed out in my arms.” His voice dipped lower. “You were bleeding out.”
Alec’s memory staggered back into place. The mission. The demon nest in the Lower East Side. The explosion. Isabelle yelling. The overwhelming pain. And then…
Magnus’s hands on him. Magnus’s voice calling his name.
And his last thought before the darkness claimed him:
“I never told him.”
He looked up now, eyes locking with Magnus’s.
“I thought I was dying,” Alec said quietly.
Magnus’s jaw tightened. “You nearly were.”
“I had one thought when it happened. Not about the mission. Not about the Clave. Not even about my siblings.” He swallowed. “I thought, ‘I never told Magnus that I love him.’”
Magnus froze.
Silence stretched between them, not awkward, but dense with something unsaid for far too long.
“You don’t have to say anything,” Alec said quickly, color rising to his cheeks. “I just…I couldn’t die without telling you. I won’t live the rest of my life wishing I had. You’re the best thing in it. You’ve been my friend, my anchor, my…” He gave a breathless laugh. “My heart. But the truth is, I’ve been in love with you for a long time.”
Magnus stared at him, stunned.
“I never said anything because I didn’t want to lose what we have,” Alec went on. “I thought… I thought maybe it was better to keep you as a friend than to risk everything. But I can’t keep pretending.”
For a moment, Magnus didn’t speak. Then he rose from the couch and crossed to the bed. He sat down gently beside Alec, careful of the wounds still healing.
“I watched you sleep all night,” Magnus said, voice low. “I was terrified. Not just because I might lose you, but because I realized how long I’ve been in love with you and never said a word.”
Alec’s breath caught.
“I thought if I told you,” Magnus continued, “it might ruin everything. When we first met you were struggling and working so hard, and I realised you just needed someone in your corner, and I could be that person. I didn’t want to risk distracting you or putting pressure on you. And I couldn’t bear to lose your friendship.”
“You don’t have to worry about that,” Alec whispered. “You’re stuck with me now.”
Magnus smiled softly, eyes shining.
“You’re so easy to fall for, Alexander,” he murmured.
Alec reached up and let his fingers graze Magnus’s. “So… this is mutual?”
Magnus laughed, breathless. “Very.”
A beat passed, and then Alec smiled, small, tired, and a little sheepish. “Okay, this might sound insane. But I was lying here thinking, if it wouldn’t be considered completely absurd because we haven’t even had a first date yet… I would probably propose to you right now.”
Magnus blinked, eyes wide.
Alec winced. “That’s too much, isn’t it? I didn’t mean it literally. I just meant…”
“Ask me,” Magnus said, his voice barely above a whisper.
Alec froze. “What?”
Magnus leaned in, resting his forehead gently against Alec’s.
“Ask me,” he repeated. “I’ve waited centuries for someone who saw me like this. Who loved me without conditions. And if you’re truly serious, then ask me.”
The world tilted slightly.
And for the first time in his life, Alexander Lightwood didn’t hesitate.
“Magnus Bane,” he whispered, lips just inches from the man who had already changed everything, “will you marry me?”
Magnus smiled. And kissed him.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The decision to keep the engagement secret hadn’t been difficult, just natural.
Alec had said it first, in the quiet calm of Magnus’s loft, their fingers entwined, the hum of morning traffic soft below.
“Let’s just… keep this part to ourselves. For now.”
Magnus hadn’t hesitated. “Ours,” he’d agreed. “I like the sound of that.”
They told their friends they were finally together, officially, and the reaction had been nothing short of joyous. Isabelle had screamed so loudly that Church had fled the room. Jace had clapped Alec so hard on the shoulder he nearly reopened a still-healing wound. Clary had teared up and hugged them both, and even Simon had managed a, “Took you guys long enough,” followed by a sheepish grin.
Only Maryse and Robert Lightwood hadn’t said anything. Not directly. Maryse had pursed her lips when she found out. Robert had made a vague, noncommittal noise. But Alec didn’t care. He hadn’t cared in years.
He had been running the New York Institute with such precision, strength, and unflinching integrity that even the Clave, rigid and prejudiced as it was, couldn’t lay a hand on him. And they knew it.
So Magnus stayed at his side, hand in hand, and their love, newly out in the open, shone like something undeniable.
And one quiet evening, Alec took the Lightwood family ring from his dresser drawer. It was old, silver, with a worn engraving of the Lightwood family crest. He held it out to Magnus without ceremony, without preamble. Just a quiet, hopeful look in his eyes.
Magnus didn’t speak. He took it reverently and strung it onto a chain he wore under his shirt, close to his heart.
They didn’t talk about what it meant out loud.
They didn’t need to.
Within a week, Alec had moved into Magnus’s loft.
It was easier than expected. Alec had never had much in the way of material possessions, and Magnus’s home, eclectic, warm, and alive, welcomed him without needing to change. A space appeared on the bookshelves for Alec’s favorite tomes. A corner of the weapons rack was mounted by the front door. A stack of Alec’s dark jeans and jackets joined Magnus’s riot of silk and velvet in the wardrobe. Somehow, it all just fit.
Their rhythms fell into sync without effort. Magnus brewed coffee while Alec checked mission reports. Alec kissed Magnus before patrol and again when he returned late at night, always. They existed in a kind of soft wonder, like they couldn’t quite believe how lucky they’d become.
And then, a month in, Alec asked:
“What kind of wedding do you want?”
He said it while they were curled together on the couch, Alec’s head resting on Magnus’s chest, Magnus absentmindedly twirling his fingers through Alec’s hair.
Magnus paused.
Alec turned his face slightly to look up. “You don’t have to answer now. I just, I’ve been thinking about it.”
Magnus smiled, but it was thoughtful. “I always assumed… something big. Lavish. Glittering, even. That’s what people expect from me, isn’t it?”
Alec gave him a look. “You don’t have to put on a show. Not for me.”
“Well then,” Magnus said, eyes softening. “What I really want… is something small. Intimate. Just you and me. Maybe a few people. Maybe not.”
Alec’s eyes widened a little, caught off guard.
Magnus noticed. “That surprises you?”
“I just…” Alec shook his head, a slow smile spreading. “I thought you’d want something a bit ..more, but actually no when I think about it, it fits. As long as you’re not just saying that because you think it’s what I want. You deserve the whole world, Magnus.”
“I don’t want the world,” Magnus said. “I want you.”
Alec’s heart skipped, but he found his voice. “That’s exactly what I want too. Honestly, if it were just the two of us and someone to make it official… that would be perfect.”
Magnus ran a thumb along Alec’s cheekbone, considering him.
“Would you want it done according to Nephilim custom?” he asked gently. “With a Silent Brother? With runes?”
Alec was quiet for a beat. “I always thought that’s how it would be,” he admitted. “But it’s not like they’d allow that. Not for us.”
He took Magnus’s hand and held it tight.
“But I’ll marry you any way I can. Anywhere. It doesn’t matter what the ceremony looks like. It’s you. That’s what matters.”
Magnus stared at him, expression unreadable for a long moment.
Then, almost hesitantly, he said, “There… might be a way.”
Alec blinked. “What kind of way?”
Magnus’s lips curved. “Let me look into something. But first, tell me, how soon would you want to get married?”
Alec didn’t hesitate.
“I would’ve married you the day I told you I loved you,” he said simply. “I’m ready whenever you are. If that’s tomorrow, I’m in. If it’s a year from now, I’ll wait. But I’m ready, Magnus. I’ve never been more sure of anything in my life.”
Magnus didn’t speak right away. He just leaned forward and kissed Alec, slow and deep, a promise made without words.
When they pulled apart, Magnus whispered, “Then let’s make it happen.”
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Alec woke to the sensation of being watched, but not in the way he was trained to expect. No shadow, no threat. Just a warmth, a hum in the air that told him he was being seen in the most tender way.
Magnus sat beside him,a strange light in his eyes. He looked positively gleeful.
Alec blinked up at him, hair mussed and voice rough with sleep. “Why are you staring at me like that?”
Magnus grinned. “Because I’ve made plans.”
Alec raised an eyebrow. “Plans?”
“Can you be done early today? Say, free just before sunset?”
The temptation to ask all the questions, Where? What for? Why?, buzzed at the edges of Alec’s mind. But then he saw the spark in Magnus’s eyes, the barely-contained excitement, and he decided he didn’t need to know.
He leaned up, kissed Magnus softly, and murmured against his lips, “Yeah. I can make that happen.”
⸻
As promised, Alec wrapped up early. Jace gave him a teasing smirk on the way out, but didn’t ask questions. Isabelle sent a text with three eye emojis and a heart, and Alec suspected she somehow knew something was up, and for once didn’t pry or press for more information. He didn’t care, he was just glad that for once he was able to organise the afternoon so he could finish early and in fact take the whole of the next day off.
He was in his office just before sunset when the golden shimmer of a portal opened beside his desk, and Magnus stepped through.
Alec stopped breathing for a moment.
Magnus looked stunning. Not just beautiful, though he always was, but regal. A dark suit, sharply tailored, was paired with a midnight-blue frock coat embroidered with ancient runes in gold thread. His hair was swept back, and his eyes sparkled like they held galaxies.
“Hi,” Magnus said, a little breathlessly. “I was going to say something clever, but you’ve made that impossible by looking like that.”
Alec flushed, but then Magnus stepped forward and held out his hand.
“Would you mind terribly if I magically changed your outfit? I’d like us to match the occasion.”
Alec didn’t ask. He just nodded, mouth dry, and let Magnus place a hand gently on his chest.
In a shimmer of magic, the change came.
Gone were Alec’s standard black gear and Institute jacket. In their place was a bespoke suit of the deepest forest green, lined with black velvet, also trimmed with gold thread, the fabric so fine it caught the light like silk. It fit him perfectly, like it had been tailored by hand.
Magnus looked him over, visibly pleased. “There. That’s better.”
Before Alec could ask anything else, Magnus extended his hand again.
“Shall we?”
Alec took it.
The portal opened, not to some grand venue or exotic world, but to something deeply familiar: the small chapel hidden deep in the Institute. A place just for the Head of Institute, and not used by anyone else.
It was quiet, just as it always was. The stained glass windows filtered the fading sunlight into soft hues of blue and gold. There were no rows of pews, no audience. Just the hush of silence and the comforting scent of old stone and candle wax.
Alec stopped in his tracks.
“This is…how did you…?”
“You’ve retreated here many times,” Magnus said, voice soft. “You don’t talk about it, but I’ve always known this place matters to you. I wanted it to be somewhere that already holds your peace.”
Standing by the altar was a Silent Brother Alec recognized but had never spoken to, Brother Zachariah. But unlike the others Alec had encountered, Zachariah’s eyes were not sewn shut. His mouth was unmarred. He looked… calm. Gentle.
Magnus guided Alec forward. “This is Brother Zachariah. His name, before the Brotherhood, was Jem. He’s an old friend of mine. One I trust with everything.”
Brother Zachariah nodded, his voice calm and steady. “It is an honor to be here. Magnus asked if it were possible for the ceremony to be done in the Nephilim tradition, and I agreed. This chapel is sacred ground. And the vows you make here, Alexander Gideon Lightwood, will be as binding as any the Clave could offer.”
Alec’s breath caught, and Magnus turned to him, taking both of Alec’s hands in his.
“There’s more,” Magnus said gently. “Zachariah told me… the wedded rune…” he paused, watching Alec carefully, “…it can be shared with someone who isn’t Nephilim.”
Alec’s eyes widened.
Magnus continued, “It’s rare. It requires protection and knowledge the Clave likes to pretend doesn’t exist. But it’s real. Zachariah can make it safe. I can bear the rune, Alec.”
For a moment, Alec had no words. All he could do was stare at Magnus, his warlock, his future, and feel something shift deep inside him. Some old ache he hadn’t even realized he’d been carrying… eased.
“I never thought…” Alec’s voice broke, and he swallowed. “I never let myself imagine I’d get to share that with someone. To wear a rune not for duty, or survival, but for love.”
Magnus gave a small, emotional smile. “I wanted you to have this. I wanted us to have this.”
Brother Zachariah stepped forward with a quiet grace and began the ritual.
There was no fanfare. No audience. No warlocks or Shadowhunters, no Lightwoods or Clave representatives.
Only Alec and Magnus.
They faced each other in front of the altar, hands clasped, foreheads nearly touching.
They spoke their vows not as the Head of the Institute and the High Warlock of Brooklyn, but as two people in love who had fought battles both public and private just to reach this moment.
“I promise to stand by your side,” Alec said, voice steady but filled with feeling. “To honor you, support you, protect you. To be your home and your partner. No matter where we are or what the world says, you will always be the one I choose.”
Magnus, eyes shining, echoed with his own:
“I vow to cherish you, Alexander Lightwood. To be your fiercest protector, your softest place to fall. I will love you through every lifetime we’re given. I will never walk away from your light, even when it burns, even when it blinds.”
Brother Zachariah turned first to Alec, his expression calm and reverent beneath the hood of his robes. “Are you ready?” he asked, his voice low and steady, full of understanding. Alec nodded, swallowing back the lump in his throat. He extended his left arm, palm up, wrist bare. The Silent Brother pressed the tip of the stele to Alec’s skin with a gentleness that surprised him. The rune bloomed into being, inked in light, and Alec felt the familiar burn, not sharp or searing like so many battle runes had been, but something deeper. It pulsed with warmth, a quiet ache of devotion, a tether of intention. It didn’t feel like obligation or legacy. It felt like love.
When Brother Zachariah stepped over to Magnus and repeated the process, Alec watched, breath caught in his chest. Magnus didn’t flinch, he never did, but his eyes shimmered with emotion as the golden flare of the rune lit up his dark skin, glowing briefly like it had been kissed by starlight before it faded into permanence.
Then, Brother Zachariah turned and silently handed Alec the stele. His meaning was clear.
Alec hesitated only for a breath before stepping in front of Magnus, placing his hand gently over the warlock’s chest. Beneath his palm he could feel Magnus’s heartbeat, steady, strong, real. A flicker of awe rippled through him at the trust in Magnus’s eyes.
“I love you,” Alec said quietly, the weight of the moment settling over them like a cloak.
He pressed the stele to Magnus’s skin just over his heart and began to draw. His hand was sure, though he felt as though he might shake apart from the intensity of it. The rune flowed into existence beneath his touch, delicate and powerful, glowing gold just like before, radiant, almost too bright to look at. Magnus exhaled a slow breath, eyes fluttering shut, lips parting slightly. The magic in the room shifted, as if the space itself was acknowledging the bond taking root between them.
When it was done, Alec stepped back, and without words, placed the stele into Magnus’s hand.
Magnus held it like it was a relic, like it meant more than any spellbook or artifact he had ever touched. He looked into Alec’s eyes, his voice thick with meaning when he said, “Your turn, Alexander.”
He reached for Alec’s shirt with care, parting the fabric just enough to reveal the space over Alec’s heart. His fingertips lingered there briefly, reverently, before he began to draw. The moment the stele met Alec’s skin, Alec felt the spark, the tether locking into place.
But more than that, he felt seen. Chosen.
The rune Magnus carved into him was the same, but in Magnus’s hands it felt like a vow spoken not just in words, but in magic, in soul. As it settled into Alec’s skin, gold light flooding and then dimming to a steady, eternal warmth, Alec’s breath caught.
Magnus’s hand remained over Alec’s heart as the rune faded into place, his thumb brushing the curve of it gently. They didn’t speak. They didn’t need to.
They were bound. Not by blood, not by duty. But by love. They were married.
Alec exhaled a shaking breath and pulled Magnus into a kiss, slow and reverent, a seal to the promise they’d made.
And in that quiet chapel, with only the setting sun and an old friend as witness, Alexander Lightwood and Magnus Bane became something permanent.
Something unbreakable.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Two days after their wedding, Alec woke to the scent of coffee and the low sound of Magnus humming something warm and familiar in the kitchen. Sunlight spilled across the floor of the loft in golden stripes. The city was waking, but their world felt perfectly still.
Alec sat up, stretching out sore but content limbs, his fingers brushing over the rune on his chest. It still hummed faintly with magic. He smiled.
Magnus glanced over his shoulder, grinning when he saw Alec awake. “Coffee’s fresh. And I made those infernal oat pancakes you pretend not to like.”
Alec stood, still in pajama pants and a loose T-shirt, padded barefoot into the kitchen, and kissed Magnus good morning.
They ate in quiet comfort, Magnus swirling syrup in elaborate patterns across his plate, Alec steadily working through the stack like a man on a mission. It wasn’t until the plates were mostly empty and the last of the coffee drained that Alec set down his mug and cleared his throat.
“I want to tell people,” he said.
Magnus blinked, tilting his head. “Tell them…?”
“That we’re married.” Alec looked at him, steady and sure. “I liked having our engagement private, it was ours, just for a while. But I don’t want to hide that I’m married to you. I never want you to feel like a secret.”
For a long beat, Magnus didn’t say anything. Then he set down his fork, his expression caught somewhere between stunned and soft.
“You… really mean that?”
“I do.” Alec reached for his hand across the table. “You’re my husband, Magnus. I’m proud of that. Let the Clave raise their eyebrows. Let my parents clench their jaws. I don’t care. I want people to know.”
Magnus stared at him like he was seeing Alec for the first time all over again. Then, with a quiet exhale that trembled just a little, he said, “You know, I’ve lived over four hundred years. And I’ve never been married. I never let myself believe it would be something I’d have. Not really.”
Alec’s brow furrowed. “Why not?”
Magnus shook his head with a small, bittersweet smile. “Too dangerous. Too temporary. Too many things stacked against it.” He squeezed Alec’s hand. “But then you came along. And suddenly I wanted it all. And now that I have it… I want to shout it from every rooftop in New York.”
Alec smiled. “We can start with the Institute.”
⸻
It didn’t take long for Isabelle to notice the wedded rune on Alec’s wrist.
They were barely five minutes into their morning check-in when she gasped and grabbed Alec’s arm, yanking up the sleeve of his jacket.
“Oh. My. Angel.”
Magnus, standing casually at Alec’s side, arched an eyebrow. “Do I want to be worried?”
“You got married?” Izzy shouted, eyes wide, grinning wildly. “You two, you got married and didn’t tell me?!”
Jace, Clary, and Simon came running, concerned by shrieks Izzy was making.
Alec blinked, caught like a deer in headlights.
Jace narrowed his eyes at the rune, then stared at Alec. “Wait. Is that…”
“Oh, it is,” Clary gasped. “You did it! You really did it!”
There was shouting, laughter, hugs. Magnus’s hand never left Alec’s.
Izzy planted her hands on her hips after she recovered from nearly weeping. “Okay. First of all: I love you both, but how dare you not invite me. Second: you will let me throw a party. Pandemonium. This weekend. No arguments.”
Magnus grinned. “Actually, that might be perfect. I invited some of my family over for dinner tonight to share the news. But a party, most definitely! That sounds divine.”
Alec looked over at him, amused. “This is the most excited I’ve ever seen you about something not involving magic or clothes.”
Magnus winked. “Marriage is a big deal, darling. I intend to revel.”
⸻
Later that evening, after the buzz of celebration quieted and everyone had returned to work, Alec stood in his office alone. Magnus had gone back to prepare for dinner, and Alec was just about to leave when there was a soft knock at the door.
“Clary?” he asked, surprised to see her.
“Hey,” she said, closing the door behind her. “Can I talk to you for a second?”
“Of course.” Alec gestured for her to sit, but she stayed standing.
“This might sound crazy,” she said slowly, “but I had a dream last night. Only… I’m starting to think it wasn’t a dream at all.”
Alec tensed slightly. “What kind of dream?”
“I saw the Angel. I was standing in Idris, at Lake Lyn, and he was there. He showed me a rune. Just one. And I… I think it was meant for you.”
Alec stared. “For me?”
Clary nodded. “It’s… I think it’s a modification of the wedded rune. One that connects more deeply. Permanently.” She hesitated. “I think… I know it’s a rune for immortality. One that could bind your life to Magnus’s, keep you from aging. From dying. If you want it.”
Alec was silent, the weight of her words crashing into him like a tide.
“I don’t know if it would work for anyone else,” Clary said softly. “But the Angel gave it to me with your face in my mind. You’re the one it was for.”
She stepped forward, placing a small drawing, charcoal lines etched carefully onto parchment, on his desk. The rune was elegant, unfamiliar, glowing with possibility.
“I know it’s a lot,” Clary whispered. “But if you want it… it’s yours.”
Alec stood slowly and wrapped his arms around her. “Thank you. For trusting me with this. And for understanding what it means.”
“I know what Magnus means to you,” she said. “You deserve forever.”
⸻
That night, after dinner was cleared and laughter echoed through the loft, Alec led Magnus to their bedroom.
He showed him the rune.
Magnus stared for a long moment, disbelief warring with wonder in his eyes.
“You’re sure?” he whispered.
“I was sure the moment I married you,” Alec said, taking Magnus’s hand and pressing it over his heart. “This just… makes it real. For both of us.”
Magnus smiled then, slow and radiant.
They carved the new rune together, side by side, over their hearts, next to the one that already bound them. It burned with golden light, shimmering into permanence.
And when it faded, they felt it: the steady, endless thrum of life, shared and balanced, as eternal as love could be.
Alec turned to Magnus, fingers brushing his cheek. “Now we have forever.”
Magnus leaned in, kissing him with all the joy, gratitude, and love of four hundred years poured into one moment.
“Yes,” he whispered. “We do.”
