Chapter Text
Even though Harry was expecting to pop out on the other side of the world, decades into the future, landing in front of ten kids who were glaring, disappointed, at the wizards was still a hell of a shock, and kind of terrifying. Especially four of the kids, a tall blond guy with a scar and a shorter girl with dark hair who both had the same intense, electric blue eyes, another tall guy, this one with dark hair and oddly bright green eyes, and a girl with Hispanic features and a dagger in her hand.
Then, so fast it just about gave Harry whiplash, everybody started grinning and yelling, ignoring the wizards as they descended on Will and Nico, who had come through after them.
After the couple had obligingly hugged and greeted every single one of them, and randomly declared that the fearsome foursome or whatever were going to Hogwarts, they finally backed off a bit, except for the scary blond guy, who had completely glommed onto Nico, and a girl with choppy hair braided with feathers and beads, and eyes Harry couldn't determine the colour of, who was doing a lengthy and complex handshake with Will.
"So," the blond guy started, voice exactly as steely as one would expect from someone who'd looked ready to kill them a minute ago. "You go to England in the past, give no information, asides that you're going to be a whole year, and you bring back six children? What's up with that Neeks?"
Nico didn't look bothered in the slightest. "Hecate wanted us to do some stuff, and apparently I have paternal instincts."
"You did a Draco again, didn't you." The guy now sounded fond and gentle, a complete one eighty. "You found some kids, taught them to be badasses, then realised that you now considered them your kids didn't you?"
Nico blushed faintly. "Yeah, maybe. Anyways, I need you and your little harem to come to the Hades cabin later. It's to do with Hecate."
The girl who'd been doing the handshake with Will glared at Nico. "Neeks you can't call us Jay's harem. If it's anyone's harem it's mine, I'm the one that can control people."
"Hang on!" The other scary guy, the one with green eyes shoved his way through the crowd of kids, looking offended. "It's obviously my harem, I'm the guy providing the palace underwater here."
Will stared at them both flatly. "Are you trying to kid yourselves? Pipes, Perce, I love you both dearly, but it's definitely Annabeth's harem. You three would literally burn the world if she told you to without questioning it."
Harry had no idea who Annabeth was, other than that Nico and Will had mentioned her being smart, but Will was obviously right, as the three didn't even try complaining, just nodded as though that was a valid assessment.
Nico suddenly flipped Jason over his shoulder. "Fuck's sake! Stop sparking at me just because you miss Annabeth!" Jason just laid there, pouting.
"But she's on Olympus." He whined dramatically. "And without her, I have no one to geek out with about the temple for Nyx, even though it's super cool! Plus I can't help the sparks, they just happen. It's like how the room gets darker every time Will forgets to come have lunch after his shift because you get all lonely and angsty."
Harry tried to catch Hermione's eye to see if she understood at all what was going on, but just as he moved to ask, a car horn sounded. Jason, Piper and Percy immediately looked at each other, beaming, before running to the top of the hill they'd appeared at the bottom of.
Nico merely rolled his eyes and grinned at the scary girl with the knife. "So, sorella, how's it going with your girlfriend?" He singsonged.
The girl blushed faintly but smiled. "It's going good. How about you and your fiancé?" She teased. "Was it a good proposal or do I need to gut him?"
"Don't worry Rey, it was suitably romantic." He smiled brightly, then seemed to remember the wizards stood there awkwardly. "Right, introductions." He looked to Will for help, who just smirked at him. "Everybody introduce yourself."
——
By the time everybody had been introduced and they'd eaten, Harry's head was spinning. He'd seen Jason fly and shoot sparks at Percy, Percy throw a river at Jason, Piper make them both stop and sit, back to back, though still holding hands, and Leo set himself on fire. At one point, Jason and Nico had played a brief game of tag, Nico vanishing and reappearing alarmingly fast, whilst Jason occasionally took off into the air to avoid him. Leo tried to get involved, but started whining and pouting once they declared setting yourself on fire to avoid being tagged as cheating.
These people were incredibly powerful, even Annabeth and Reyna, who had no visible powers exuded an aura of quiet confidence and intelligence that made Harry want to obey their every word. He was absolutely exhausted by the time they retreated to Nico's cabin with Jason Percy, Piper and Annabeth, who turned out to be a pretty and athletic looking blonde with intelligent grey eyes, although he wasn't entirely sure why they were coming.
——
Nico's cabin was absolutely incredible. It was all black obsidian walls and green fire on the outside, but the inside was the absolute height of luxury. There was overstuffed sofas, a little kitchen, and two huge beds.
"Do all the cabins look like this inside?" Ron asked, running his fingers along what looked to be a solid gold fruit bowl holding pomegranates."
Piper laughed. "Not at all. Neeks has the nicest cabin. Jay's cabin has Zeus the cock block, Percy's cabin has a fountain, Annabeth's cabin screams sleep is for the weak, and my cabin looks like barbie threw up in it."
"Zeus the cock block?" Hermione repeated, looking vaguely sick.
Jason nodded mournfully, flopping onto one of the beds. "There's this massive statue of Zeus in the middle of my cabin, and no matter where you are, he can see you. I don't know if you've ever tried to have a foursome whilst a statue of your dad watches you, but I wouldn't recommend it."
"It's ninety percent of the reason we got our own place." Percy agreed solemnly, laying half on top of Jason. "It's like a mythological boner killer."
"We got our own place because we started university, seaweed brain." Annabeth sat next to Jason, manoeuvring him til his head was in her lap. "But yeah the Zeus statue is a huge turnoff." She conceded.
"Anyway," Hermione cut in. "How come your cabin is so fancy, Nico, if no one else's is?"
"Partly because my dad is the god of wealth, and partly because I built this place."
"Woah.." Luna looked around. "How did you get the place to look smaller outside than it is? I've seen illusions like that back home, but I assume this was without magic?"
Nico blushed faintly. "Uh, I have no idea? I told Annabeth how I wanted it to look, she drew me some blueprints, then I gave it to some skeletons and they built the outside. Then I pestered my dad until he gave me his credit card, and I got the furniture like that." He sat against the headboard of the other bed and tugged Will down until they were leant against each other.
"No matter how many times I hear it, I'm never gonna get over you casually saying stuff like you pestered the lord of the dead until he gave you a credit card." Piper muttered, tucking herself into Annabeth's side. "I mean, we've all met our parents, and Percy's dad is chill, but then you'll just pop up like oh me and my dad are going to see Fall Out Boy together, does anyone want to come?"
"We had such good seats though, Pipes." Percy grinned. "Nico can do whatever he likes with his dad as long as we keep getting free stuff."
"I'm glad to know where I stand." Nico remarked, then motioned for the wizards to make themselves comfortable. "Now, about what I said earlier. Hecate says we can bring four people to Hogwarts and I chose you."
They all started yelling, Annabeth saying they had university, Piper mentioning something about surfing competitions, and Percy declaring he was done with helping gods. After a solid five minutes of protests, they finally shut up, and Nico smiled at them. It was the polite, terrifying smile he pulled out whenever he knew he was about to get his way.
"Annabeth, darling, it's an early fourteenth maybe fifteenth century castle in Scotland with moving staircases and a maze of tunnels and passageways that have only ever been fully mapped once. Percy, there's a massive lake with a giant squid and mermaids. Jason, there's a sport that involves flying and throwing things. Piper, you can use charmspeak all you like and tell them you're just a really powerful charms caster. Convinced?"
He gave them a moment to think it over, and after whispering to each other for a minute they agreed.
Will smiled brilliantly, and the room brightened considerably. "Awesome. Now the term starts on the first of September, and Annabeth I presume you'll want to see Diagon Alley, and Jay you'll want to buy a broom, so we'll stay here til the last week of August. Sound good?"
"Where are the wizards staying?" Annabeth asked, once they'd all agreed. "We don't have that many beds in the Big House and Hecate's cabin is too dangerous for non half-bloods."
"We're staying in the city." Nico responded after a minute of him and Will looking at each other in panic. "Dad has a penthouse suite there, loads of beds. You're welcome to drop in and stay if you want, it's pretty close to your place."
Annabeth sighed. "You didn't think about it, did you?"
"Nope." Will shrugged. "Hecate only told us she'd arrange for them to withstand the travelling through time like two days ago. Then we forgot that most humans need space to live in and can't go sleep in the underworld if there's no space."
"Exactly." Nico nodded sagely. "Like that time Jason forgot that most humans can't withstand Mach 3 and almost killed the three of you, or the time Percy forgot that most humans won't survive being a mile underwater."
Annabeth raised an eyebrow. "Will doesn't have weird powers that make him forget the limits of normal humans."
Ginny raised her hand. "One time the lights went out in Hogwarts because Nico was pranking Umbridge, and Will forgot that not everyone can glow in the dark so he just kind of left us the try and navigate our way through."
"Why would you tell her that! Now she thinks I'm as bad as those three!"
Seamus was grinning. "She never said you were as bad as Nico. One time," he turned to Annabeth, "Will asked him where our bags were, and Nico seemed genuinely confused, and asked him why would he carry a bag around when he can get anything he needs from the shadows, and then he pulled his cat out."
Dean piped up. "He actually forgot that most people can't do that, and that Will was mainly talking to us."
——
Harry had no reason to be scared of Jason Grace. The past few weeks had shown him that. Jason would spend hours curled up with Nico in some hard to find high up place as they binge watched shows like Avatar the Last Airbender and Daredevil. The guy was practically a teddy bear as far as Annabeth, Percy, and Piper were concerned, and he'd happily bake for the whole group of them during their stay. He was super sweet and smart and..
Well... he was also Harry's boyfriend's big brother..
And although Draco's actual, legal, dads, Will and Nico, completely approved of their tentative and slow moving relationship, once Harry's sixteenth birthday had come around, Jason had started glaring and sparking around a Harry. When Nico had first mentioned it, Harry had expected static shock, or something similar, not actual, glowing blue and gold sparks firing off Jason's skin. It had, at least, made for quick bonding between him and Seamuss, and subsequently a talking point for Piper and Dean.
It all came to a head, naturally, on the day before they returned to England. Hecate was due to arrive at around twelve to take them and to transform the demigods to a younger version of themselves, and Jason had taken it upon himself to cook breakfast. The four demigods had decided to stay with Nico, Will, Draco, and the wizards on the last few days of their holiday.
Jason was in the kitchen, shirtless as he usually was on a morning, torso well defined, and littered with scars. He smiled brightly when he saw Draco and Harry enter. "Dragon, Harry, morning." He hugged Draco with one arm as he poured himself a coffee.
"Harry, do you think I could borrow you for a moment?" Jason motioned to the door. "I just want to ask you something."
He glanced at Draco, who nodded. "Uh. Yeah? Sure."
Jason grinned and led him out. As soon he shut the door, his entire demeanour changed, and Harry was suddenly reminded that this guy had fought wars, killed Titans, and was considered more ruthless than both pre-fifth-year-Draco and Nico by the two boys. "I just wanted to make sure we were both clear, that although Draco is very mature and well protected, he is still two years younger than you, and if you push him into everything, I will happily electrocute you well beyond organ failure until I deem you sorry enough, even if I need Nico to hold your spirit in place while you apologise. Understand?"
Harry nodded frantically. "Yep. Super clear. One hundred percent understand."
Jason relaxed and smiled at him. "You're a good kid." He led them back into the kitchen, and ruffled Nico's hair on the way past.
"Neeks, how tall were you at fifteen?" He asked out of nowhere.
"Uh, probably about five foot five?" Nico shrugged. "Why?"
Jason suddenly looked horrified. "Percy..we have a problem."
Percy looked up from where he'd been half asleep on the counter. "Hmm?"
"I didn't hit my growth-spurt until I was sixteen. I was five four when I was fifteen. Nico is gonna be taller than me." He complained, slumping onto the barstool next to him. "Will you still love me when I'm shorter than Nico?"
Percy snorted. "Not a chance babe. I'm only with you because you bring up the average height of this relationship."
Will and Annabeth came in from their run, panting and flushed, both in running shorts and tank tops.
"Annie!" Jason turned to her. "Nico said he was five foot five when he was fifteen and-"
Will snorted, cutting him off. "Jason, Nico was barely pushing five three when he was fifteen. He's twenty and he's only five six now. Besides, if this is about height, and I'm assuming it is, everybody will be sixteen, so you'll be the height you were when we met you, which was tall."
Jason whipped his head around to Nico, who was half collapsed, using the wall to support himself as he laughed.
"You little bastard."
——
Hecate didn't seem to like Percy very much. When she'd shown up, and Harry sure as fuck had never expected to be sat in a penthouse suite in a high rise in Manhattan in 2019 with a goddess, she'd spoken to every one of the demigods except Percy, asides making a snide comment about how he was a good guinea pig.
Harry had expected their transition to sixteen to be the same smooth changing that happened to Will and Nico, but Hecate's distaste for Percy must have had some effect, because the four groaned like they were about to throw up, crumpling slightly as their bodies rearranged.
Piper was the first to recover, staggering back to her feet. "Nico, coffee." Something about the way she said it had pretty much everyone in the room, including Harry, inching towards the fridge, but Nico just smirked at her. "I hate to break this to you, McLean, but of all the people in this room who are at all attracted to women, you picked the only one who isn't."
"Nico I swear to my mom, make me a coffee." She glared at him.
He sighed. "Fine. I assume you asked me becau-"
"Exactly." She cut him off, gesturing to the kitchen as her face turned a bit green and she curled back over.
By the time Nico returned with a tray holding four steaming cups, the four of them had recovered slightly. Only Percy looked different, what with his features becoming less sharp and the slightly splintered look to his eyes fading, although Jason had a fresh looking cut in place of where a scar had been on his neck.
They all held their hands out for the cups Nico offered. "If you drink them too fast, you'll explode." He chided when Percy tried to chug his.
"What is that?" Hermione asked, looking a little annoyed that things weren't being explained.
"Not a clue." Nico responded. "Will just came home from being with his dad one day holding this tub. He says it's some healing mineral mixed with coffee grounds, but his father is weird as shit so I don't know if I trust that."
Hecate frowned. "You could do to be more respectful, son of Hades."
He raised an eyebrow at her. "What are you gonna do? Smite me so I can go become a god and then fuck with you for all of eternity?"
"Neeks..baby..what the fuck." Will covered Nico's mouth with his hand, smiling apologetically at Hecate. Percy was beaming like a proud father though, and even Annabeth looked grudgingly impressed.
Hecate just stared at him disdainfully until Will had dragged him away, then addressed the rest of the room. "If everybody could line up please."
Once they'd done what she asked, and Will and Nico had gathered a few things to take with them, she waved a hand, dropping them off just outside the Leaky Cauldron.
Will bowed slightly and made a magnanimous hand gesture towards the door. "Welcome to the wizarding world." He declared.
