Summary: Nico di Angelo has a new best friend – Magnus Bane, son of Hecate. Magnus' arrival at camp had been about the most exciting thing to happen since the end of the Giant War.

At least until the Shadowhunters arrive. Jace Wayland, son of Apollo, Isabelle Lightwood, daughter of Aphrodite, and Alexander Lightwood, son of Athena. Demigods from Idris – the European version of New Rome, where demigods call themselves Shadowhunters. They came with a mission, to track down someone who had played a key role in setting up the Giant War many years before it had actually happened. Valentine Morgenstern. The three European demigods ask and receive the help of Camp Half-Blood and Camp Jupiter.

And Nico finally gets some revenge on Magnus for always teasing Nico about his feelings for Percy Jackson, because oh, Magnus also seems to know how to pick them...

Shadowhunters: The Heroes of Camp Idris

When the Europeans Come to Visit

Chapter 7: Reyna and Lydia

Lydia blinked slowly as she and Max stood to await their heroes back. They didn't want to make a big deal out of it, she needed to talk to Alec and the others first before they could announce anything. She was hopeful they succeeded, but she couldn't be sure. What she had definitely not expected was them arriving with a flying ship. With strangers on board. The first one to greet her was her girlfriend, Isabelle tackling her with a hug and a deep kiss.

"Hey, babe. We're back. We brought friends", grinned Isabelle. "And Valentine."

"Y—You did?", asked Lydia surprised.

"One thing at a time, Izzy", sighed Alec as he pushed past to hug his best friend and co-leader. "Hey, Lyds. I hope things were better on your front. It was a bit chaotic, but why don't we move this to the office to talk it through...? After securing the prisoners."

Lydia nodded, suspiciously eyeing the strangers. Max all the while had less trouble with them, he went to hug Isabelle and Alec and then Jace overly enthusiastic. The youngest Lightwood had been really frustrated that he didn't get to go along on the quest; he loved his siblings and Jace was his personal hero. It had taken them a lot of convincing to make him stay.

"Who are your friends?", asked Max curiously.

"That's gonna take a while", muttered Jace with a half-grin. "Come on, let's move this to the Institute. You can help me assign rooms to everyone and I'll introduce you. Half of them are children of Hecate. This one too. That's Magnus Bane. My new boyfriend. Alec's new boyfriend."

Max raised one eyebrow and looked at Magnus critically. "Son of Hecate? That means you have magic, right? Can you perform a trick or something...?"

"What you might love even more than Magnus' magic is Leo's fire", stated Jace.

"Excuse me?", huffed Magnus offended, earning a peck on the cheek from Jace.

When Leo summoned a small flame and Max yelped in utter delight, it became apparent that yes, fire was indeed more impressive to Max than magic. That little pyromaniac. Lydia rolled her eyes fondly as she watched Max talking animatedly with the new arrivals when they left. Alec parted ways with them to go and talk to Lydia. The only ones following him were Reyna and Annabeth, the rest going with Jace and Max. Lydia watched curiously until they reached the office.

"Now, who are our guests, Alec?", asked Lydia when she sat down behind her desk.

"Reyna, the praetor of Camp Jupiter, and Annabeth, the leader of Camp Half-Blood", introduced Alec. "This is Lydia, my co-leader of Camp Idris. Lyd, they're here for... diplomatic reasons."

"Now that we all know about each other, we figured we should get to know each other", offered Reyna with a polite smile. "We thought we'd tag along to visit your camp and city. But you are more than welcome to also visit New Rome whenever you want to."

"And Camp Half-Blood, of course", added Annabeth with a smile.

Lydia raised her eyebrows at that. It was an interesting concept. Forming alliances, getting to know each other, learning that they could trust each other and help each other. She liked it.

"I'm happy to welcome you in Alicante, then", smiled Lydia.

/break\

Nico and Percy were on a date. An actual date. Alicante was beautiful, a large city with so many things to offer. Jace had shown them around some, showed them the best hang-outs – the Jade Wolf, Taki's Diner and the Hunter's Moon. Currently, Nico and Percy were at Taki's Diner, having dinner.

"This place is amazing", whispered Percy, looking around.

"I've been to better diners", shrugged Nico, poking his pancakes.

Percy kicked him under the table. "The city. Alicante. It's beautiful. I mean, New Rome was kinda impressive, but it's so old-fashioned and so... Roman. This is... Greek and modern and fun."

"What are you saying, Perce?", asked Nico curiously, offering a piece of pancake to Percy.

Gladly opening up, Percy accepted the pancakes and licked his lips. "I mean that... I should be looking into colleges. And I thought New Rome was my only option. But the last few days here... I like this place. This city. I'm saying that... maybe... I actually have a choice."

Nico hummed and looked out of the window. "I guess it could be nice, living here. With you."

"W—What? Living here, with me?", sputtered Percy doe-eyed.

Nico shrugged, a little flustered. "I mean... I want to go to college too. I want to become a doctor. I only ever stuck around camp because of you. And now that... you're my boyfriend, do you really believe I wouldn't just... stick around here? I love you, Perce."

Blushing, Percy leaned over the table to kiss Nico. "I love you too."

"You're both way too cute. It's disgusting", snickered Jason.

Him and Reyna walked over to the booth and then just slipped in with them, Reyna next to Nico and Jason next to Percy. Jason stole Percy's fork and used it to steal from Nico's pancakes.

"I could just shadow-travel you to the Antarctica", drawled Nico pointedly.

"Dude, you just said you won't move to New Rome, to me, the least you owe me is pancakes", complained Jason, looking like a miserable puppy. "Rey, back me up on this one."

"He just promised his boyfriend that in a year's time, they might be living together", shrugged Reyna. "And you are the one who has been rooting for them the hardest, so don't pretend."

Jason stuck his tongue out at his girlfriend. "Okay, fine. But I just... I'll miss him."

"...I can shadow-travel. Whether I live in Europe or in New York will literally have no impact on how often we see each other, Grace", grunted Nico and rolled his eyes.

"But I thought you'd study in New Rome", huffed Jason. "I had already planned our apartment."

Reyna, Nico and Percy just stared at him pointedly while he continued eating Nico's pancakes.

Annabeth was fascinating. Lydia was definitely determined to stay in contact with her new-found half-sister. They were rather similar, but what Lydia found particularly endearing was Annabeth's obsession with architecture. And Alicante with its class buildings left Annabeth in so much awe.

"My girlfriend is so cute", grinned Piper where she was walking on Isabelle's other side.

Even after a week, Annabeth still walked around with an awe-struck expression on her face. Lydia, Reyna and Annabeth had come to the agreement that their communities needed to be more open with each other. Exchange programs, many from Alicante had already signed up to fly back with the Americans to visit New Rome. Percy and Nico had also already approached Lydia and asked if there would ever be the opportunity for them to study in Alicante. It was a nice idea, especially when Reyna put it on the table that the Europeans could come and study in New Rome too. It all needed to be finalized, to be worked out between the colleges, but the idea was solid.

"How's Jace doing?", asked Lydia tentatively, looking at her girlfriend.

Isabelle heaved a sigh and shrugged. "You know him. He doesn't like to admit weakness. But that we caught Valentine and that he's now in prison... I think it makes him lighter. But I also think that the second boyfriend he brought back from the US helps with that too."

Lydia chuckled at that. Magnus Bane was an interesting character and she had seen him around town with both Alec and Jace by now. The three seemed happy with each other. If they could make it work for themselves, then Lydia was all for it. She knew first-hand that Alec was always working too hard, was being too serious. Jace helped softening him and Magnus seemed too. She was curious to see where it would lead them on the long run.

/break\

Alec sighed exhausted, blinking slowly as the papers were taking away from him by a stern-faced Lydia. The Americans had left a month ago and now they had all the paperwork to do. Percy's suggestion of student exchanges – and not just for the colleges to take each other in, but also short-term student exchanges for their high schools – was great and it was the perfect way of bringing them all closer together. Max had left Alicante with the Americans. Only for the last two weeks of summer, that had been important to Alec, but he also understood the fascination. And Max had been very fascinated, especially by Frank and Reyna, who shared his godly legacy. Frank had made promises to teach Max how to shoot even better than Alec. The thought made Alec snort. The more frightening thing was how good Leo and Max had gotten along.

"You're spacing out. Go home, Alec", ordered Lydia gently. "Or I'll call Jace and Magnus."

Glowering at his threatening best friend, Alec got up. It was already pretty late. He really should call it a day. Sighing, he hugged her briefly before making his way back toward his room in the Institute. It was one of the two largest, most pompous, which came with the profession. Magnus seemed to feel quite at home there too. Despite having been assigned his own room at first, he had spent more nights in Alec and Jace's bed than his own, right from the start. With a wide yawn did Alec unlock their bedroom door, though he was quick to enter and close it behind himself when he saw what his boyfriends were doing. Jace was sprawled out on the bed, with Magnus between his legs, pinning Jace's wrists over his head while slowly fucking into him. There was absolutely no sight more beautiful than Magnus and Jace together. The way their bodies moved together, how they fit together, their skin covered with sweat and bite-marks.

"Wa—anna join in, Alec?", asked Jace with a lazy grin.

"Mh, I have been wondering what to do with that loud mouth of his", hummed Magnus mischievously. "Alexander, would you care to... occupy our angel's mouth?"

Alec made a soft noise at that and started stripping down quickly. He nearly stumbled over his own clothes on his way, making Jace laugh softly. At least until Magnus pulled out of him and flipped Jace onto his stomach. Slapping his flank, he made Jace get up on all four. More than gladly did Alec take a seat in front of Jace, his fingers finding their way into Jace's golden hair. Licking his lips slowly, Jace leaned down and swallowed Alec whole. Alec groaned and leaned back. Once Jace had Alec down his throat, Magnus grasped Jace's hips again and started pushing into him. Jace moaned around Alec, making the son of Athena shudder in delight.

"See, if you hadn't worked so long, you could have joined us sooner, darling", teased Magnus.

He reached one hand out to pull Alec into a kiss, with Jace stuck between them, impaled on both their cocks. They knew Jace loved it that way, well they both loved it that way too.

"Now that Alexander is here, you're allowed to to come, angel", whispered Magnus.

Jace made a muffled, delighted sound at that and came into Magnus' fist, tightly wrapped around his cock and jerking him off. And as always, Jace started to glow. An Apollo-thing, one that Magnus had been very delighted to see. It was beautiful. Jace melted a little between them, though he didn't stop sucking Alec off, his tongue as cunning and tricky as ever. With that, Alec didn't last much longer either. He didn't have much energy to begin with. Groaning, he came into Jace's awaiting mouth, locking eyes with Magnus and watching how the son of Hecate hit his own orgasm, deep inside Jace. Gently, Alec eased Jace off his own cock and helped Magnus adjust them so they were all laying together, with Jace stuck in the middle between them. Alec leaned in to kiss Jace deeply.

"I really shouldn't be working so long", mused Alec teasingly.

"I talked to Percy today", yawned Jace softly after a long moment in which they were all slowly drifting off. "He says that him and Nico would be moving to Alicante this fall."

"Mh, that's going to be fun", smirked Magnus, gently playing with Jace's hair.

/break\

Reyna smiled faintly when she put down one of the heavier boxes in the kitchen. Leo was chatting with Percy, about both their plans for the future – Percy who wanted to become a teacher and Leo who wanted to open up his own mechanics shop. Frank and Alec were being completely useless, both comparing new arrows instead of actually helping. Well, Magnus wasn't much better, he had used his magic to transport the couch into the living room and then promptly sat down on it with a cocktail, claiming it had drained him to use his magic like that. The only ones actively working were Reyna, Nico, Hazel, Lydia and Jace. Annabeth and Piper had allowed themselves to be stolen by Isabelle who had something 'very amazing' to show off, whatever it was.

"This is actually happening, mh?", asked Reyna softly as Nico stepped up to her.

"Me moving in with Percy? Apparently", muttered Nico, smiling a little.

"I'm proud of you, Nico", whispered Reyna, nudging her best friend.

"For banging Percy? Me too", grinned Nico slyly.

Reyna cleared her throat and rolled her eyes. "I was talking about how you overcame your internalized homophobia, stood up for yourself, came out, started socializing, actually managed to get your high school diploma even without ever having attended middle school and now going off to college to become a doctor while moving in with the love of your life."

"...You should start writing inspirational books or something, di Angelo. Your life's pretty much a success story", grunted Jace with one eyebrow raised in teasing.

"Yes, it is", chimed Percy with a grin, pecking Nico's cheek. "He's so lucky to have me."

Nico rolling his eyes and wrapped his arms around Percy to pull him into a proper kiss. "Sure am."

"So disgusting", snickered Jace, smirk on his face growing. "This is your apartment. Work."

With a huff did Nico and Percy break apart and return to their tasks. There was a lot to do. They wanted to, at the very least, have the kitchen done and the bed in place by tonight. It was a lot of work, moving their lives here, but together with the help of their friends, they got the basics done.

After all their friends left, the Americans shadow-traveling with Mrs. O'Leary and the others just returning to their own places, Percy and Nico laid on their backs on their new bed, staring at the ceiling. Rachel and Clary had promised they'd come visit soon and paint their walls. No boring one color thing, but actual art. Ocean-themed for the bathroom and underworld-themed for the bedroom. It'd be amazing. They couldn't wait to see what the place would look like when finished.

"So...", drawled Nico, one arm under Percy's head and the other folded on his own stomach.

"Mh?", asked Percy, nuzzling into Nico, nibbling his neck.

"We going to break the new bed and place in, or are you too tired?", questioned Nico.

There was hunger in Percy's eyes when he looked at his boyfriend. "The day I'm too tired to have sex with you must be the day we're super old and gray in an old demigod home and I spent the day playing bingo with Jace and Leo until I just couldn't anymore."

Nico snorted at the specifics before kissing his boyfriend. "So, that's a yes to sex?"

"That's a yes to sex", purred Percy and rolled them over to straddle Nico's waist.

Nico grunted pleased as his boyfriend started pulling both their clothes off until they were left naked. The view was amazing, seeing Percy on top of him like that, muscles flexing, sea-green eyes dark with lust. Even after two months of dating Percy, it still was an absolute miracle to Nico that Percy Jackson was his boyfriend. His boyfriend. Smiling pleased, Percy bent down to kiss along Nico's chest. Nico groaned as the teeth scratched down his chest. Reaching out, Nico buried his fingers in Percy's hair, tugging and then pushing a little, pushing him further down. Percy was more than glad to kiss down to Nico's cock, licking it and nibbling it until it was fully hard. When it was, he wrapped his lips around it and started sucking it in with gusto, coating it with spit. Blindly, he reached up to press his fingers against Nico's lips, giving him something to suck too. Once Percy's fingers were slick enough, he pulled them out of Nico's mouth and then guided them to his own hole, carefully prepping himself. It didn't take him long to be ready – they did have sex this morning – so he pulled off Nico's cock with a plop and then sat up to straddle the son of Hades once more. Slowly, he pulled his cheeks apart and lowered himself onto the hardness.

"Fu—uck", groaned Percy, pressing his hands against Nico's chest for support.

"Sh, so good", crooned Nico gently, grasping Percy's waist.

After a few moments, Percy started riding Nico hard. They kissed messily while fucking, one of Percy's hands jerking himself off while the other was still pressed against Nico's chest. Percy's moans were swallowed by Nico's lips as he came over both their chests. His thighs quivered as he continued riding Nico until the son of Hades also came. As soon as that happened did Percy collapse forward on top of Nico. Smiling, Nico caressed Percy's hair gently.

"I love you, amore", whispered Nico gently.

"Mhmh, love you too, Neeks", yawned Percy softly.

/break\

Magnus sighed contently as he fanned himself with one hand, a cocktail in the other. He sat comfortably with Nico, Alec and Madzie in the arena of Alicante. And while Magnus and Nico were thoroughly enjoying the show, Alex was braiding Madzie's hair. The little girl had really taken to Alec and Jace, as soon as she realized that Magnus really loved them.

"This is my favorite pastime", sighed Magnus contently, sipping his cocktail. "If only I could motivate Alec to join them down there. Mh... what a beautiful image..."

Nico snorted, emptying his own cocktail. Percy and Jace were down in the arena, sparring, both shirtless. A group of twenty young teens were watching avidly, trying to copy their moves as Percy and Jace taught them. It was always something that Nico and Magnus never missed. Alec, while also a huge fan of half-naked and sweaty Jace, already knew he could get that as often as he wanted to, so he rather bonded with the new kind of adopted stepdaughter.

"Alec's not paying attention", complained Jace with a glare.

Percy craned his neck enough to look at the stands. Magnus and Nico, the utter perverts, were drinking and ogling them. Alec however was braiding Madzie's hair, which was kind of ridiculously cute. Grinning, Percy judo-flipped Jace and then pinned the blonde to the ground, straddling him.

"He will look", chuckled Percy – and yes, he could feel the prickling in his neck, someone glaring.

Sparring was one thing but straddling Jace was something that Alec did not appreciate. The son of Athena was glaring daggers at the back of Percy's head while tying the second braid with a purple band. Madzie turned to smile at him, distracting him from the glaring.

"You looking forward to the summer, Madz?", asked Alec with a smile.

They had promised her that she could visit Camp Half-Blood this summer, together with Max. Max had promised to keep an eye on her and protect her, in case anything happened. Not that they really believed that, but being demigods, they could never be a hundred percent sure.

"Ye—es. I wanna see Lou again", nodded Madzie excitedly. "She was so cool! And Leo!"

Magnus sighed dramatically. "Her old dads are so uninteresting compared to the new kids."

Madzie rolled her eyes, but leaned up to kiss his cheek. It made Magnus smile gently. Watching them, Nico had to smile too. There was a feeling in his gut, an odd one. Happiness. He was happy. With Percy, with his friends, with college. He knew, one day, he would be a doctor. And one day, him and Percy would adopt an orphaned demigod just like Madzie. One day.

Author's note: Sooo, this is the end, my friends. I hope you enjoyed this crossover! Thank you for reading and even more so for reviewing - you know, those things fuel authors. ^o^

Now, as always, one closed multiple-chapter story will be replaced by another multiple-chapter story. In this case, a Voltron Shklance fic titled "Blood and Fur and Salt-Water". So, I hope to see you around there, or at least in my various other PJatO and Shadowhunters related fics. ;)
