Nico's POV

Nico just wanted some lunch. Contrary to popular belief, Nico did eat sometimes. In fact, he was on his way to a nearby McDonalds. He did not expect to be attacked by five hellhounds, and he certainly did not expect to land up in London. Well, it all started on his walk to the fast food joint.

Nico was walking, his hands in his pockets, deep in thought. His appetite was slowly coming back from after the giant war. McDonalds was one of his favourite places to eat. Besides, happy meals made good offerings for the dead. That was when the hellhounds attacked. Nico was so lost in thought, he realised too late. Spinning around, his stygian iron blade in his hand, he faced the hellhounds. There were five of them. What in Hades were they doing here? Nico glanced around. The few mortals nearby weren't paying any attention to them. Great, he thought, people will probably think I'm attacking cute harmless strays.

He stood in a defensive pose, ready to send the hellhounds back to Tartarus. The first hellhound pounced at Nico. He swiftly dodged it, stabbing his sword into its side. One down, four to go. The remaining hellhounds surrounded him, boxing him in.Nico contemplated shadow traveling away, but he didn't want to leave them with the mortals. Monsters usually stayed clear of mortals, but he could never be too careful.

Then all hell broke loose. All four of the hellhounds bounded toward him. He managed to stab one, but he was overwhelmed. Claws raked across his shoulder of his sword arm, tearing his flesh. Nico bit down a scream. He had been through so much worse, and he was not going to go down due to some hellhounds. A surge of energy filled him. He raised his arms, and ten skeleton warriors emerged from the ground. The hellhounds didn't stand a chance. Soon, they were reduced to no more than fine, golden dust. Nico leaned against a wall, exhausted. He looked at his left arm. It was bleeding pretty badly. He dug into his pockets, hoping to find some ambrosia. Well, schist. He found nothing. He would have to go back to Camp Half Blood for supplies.

Clutching his bleeding arm, he disappeared into the shadows.

Nico didn't think his day could go any worse. It did. Nico reappeared at some residential area he didn't recognise. Yeah, this is totally camp, he thought sarcastically. Nico rarely landed up in a wrong location anymore. He blamed it on his injury. Looking around, Nico realised that the house right in front of him was radiating death. The house was weird. It had a worn set of front steps, leading to a battered door. On the door was a silver knocker in the shape of a twisted serpent, with no keyholes, handles, or anything else that would indicate it to be a door. So, Nico did the next most natural thing. He walked up to its doorstep and knocked. He could have easily shadow traveled in, but he didn't want to give the inhabitants a surprise. They could be mortal, after all.

Nico stood there awkwardly for a while. What if nobody actually lived there? That would be embarrassing. But he was sure the house was important, something told him so. Besides, they might have something to help his wound. He read the address. It took him a while to decipher, but he made out '12 Grimmauld Place'.

Suddenly, the door burst open. There were around five people(what's with the number five?), and they were all pointing some stick things at Nico. He was taken aback. These people were definitely not mortal, although they didn't seem like demigods either. The strange people also looked surprised at Nico's appearance. Then, one of them shouted something. A red jet of light shot out of his stick, straight towards Nico. Nico barely had time to draw his sword. He had no idea what was going on as he rose his sword blocked the red jet of light. It was not every day that Nico met sick-wielding maniacs. Surprisingly enough, his dark stygian iron blade absorbed the light. He winced. It was a big mistake to block it with his bleeding hand. Why did the hellhound have to injure his sword arm? Transferring his sword to his right hand, he eyed the strangers suspiciously.

Some of them were gaping in disbelief. Nico guessed that this was their first encounter with a demigod. Well, he was going to make a lasting impression. He blocked a couple more jets of light, before raising the shadows. He made a barrier of shadows in between them, which deflected most of the spells. It worked for a while, but Nico overestimated his strength. He was already exhausted from his previous encounter with the hellhounds, not to mention his wounds. The barrier collapsed and Nico sank to the ground. His only though before passing out was that Will would be mad that he had done way too much 'underworldy stuff'.

Harry's POV

Harry was eating lunch with his friends and the order when the alarm rang. Moody shot out of his chair. "Someone has broken past the wards. Molly, take the children upstairs. This could be a death eater we're dealing with. Rest of you follow me." Harry, Ron, Hermione, the twins and Ginny, were quickly shoved upstairs. Mrs Weasley gave a warning, "don't try to be a hero," before locking all of them in a Harry and Ron's bedroom.

Harry's heart was thumping. Was there really going to be an attack on them? Were the death eaters here for him? He glanced at his friends' faces. They all looked worried, even Fred and George. He vaguely heard shouts of "stupefy" and "expelliamus". He looked outside the window, but he couldn't get a view of the front door from there. One thing seemed strange. The sky was abnormally dark. Harry shivered.

Then, as though nothing had happened, the sky returned to it's bright normal self. Harry turned to his friends, wondering if they had seen the change too. They hadn't. All of them were crowding around the door, trying to hear what was going on. Harry joined them. He could barely make anything out, but it seemed like a body was being dragged along the floor.

"Do you reckon they caught the death eater?" Ron asked.

"You don't know if he's a death eater!" Hermione replied, irritated.

"Well, who else will attack here, the headquarters of the order?" Harry countered. Hermione mumbled something under her breath, unhappy that she was outmatched. "C'mon, let see what they are doing!" Fred and George said together. Hermione's protests that it was dangerous was drowned out by the rest of them, as they sneaked downstairs.

Nico's POV

Nico's head hurt. Where was he? He opened his eyes slightly. Nico found himself in the center of a dark room, his attackers deep in conversation. He listened.

"He is merely a boy!"

"I don't care, he used the dark arts, some form of Umbrakinesis, nothing I've ever seen before."

"Does that mean Voldemort is recruiting children now?"

"No idea, but our location is compromised. We can expect more attacks soon."

"I've called the rest of the order back. Severus is bringing some veritaserum."

Nico realised with a start that they were talking about him. He scowled. Who were these people anyway? Nico had never seen anyone use sticks to channel power before. He tried to reach for his sword, only to find that his hands were bound to the chair, and his sword was lying out of reach. He closed his eyes, and tried to shadow travel out of the building, only to find that it didn't work.

"You can't apparate in or out of this place." said a gruff voice. Opening his eyes in surprise, Nico found that all the strangers were now staring at him.

"What do you want?" Nico growled, releasing some of his aura. The effect was immediate. Some of them backed away, looking nervous. Then suddenly, Nico sensed it. A soul, that belonged to the underworld, just behind the wall. The soul of Tom Marvelo Riddle. "Who's behind the door?" he asked in a low voice.

The man with a weird glass eye snapped, "We ask the questions not you, and no ones behind the door." Nico raised an eyebrow. What were they hiding? To prove his point, the man threw the door open. Right behind the door, were six teenagers around Nico's age. The one in the middle, the one with the dark hair and green eyes, was the one. Nico was surprised at how young he looked. Nonetheless, he was sure that he had the soul of Riddle. "You. Your soul belongs to the underworld. You can't escape any longer-" Nico glared at the boy, not noticing the red bolt of light that knocked him out again. Just before he faded into unconsciousness, Nico realised something odd, the boy had two souls.

Harry's POV

Harry was in shock. First, the death eater knew they were behind the door. Second, the death eater was a boy that could be younger than Harry. Third, he had threatened Harry. The most unnerving thing was his stare. Harry felt like the boy could see right through his soul. Not only that, it radiated fear and death.

Right after that incident, they were rushed back into their rooms by Mrs Weasley. She gave them a stern warning not to leave, but this time, none of them wanted to.Harry was filled with dread. Voldemort now knew where they were, and he would try non-stop to kill him. Harry sat on his bed, dejected. He heard the rushing of footsteps downstairs as more members of the order arrived.

"How did he get past the Fidelius Charm?" Hermione asked. No one had a clue. Only the most advanced practitioners of dark magic would be able to pull that off. "What is Umbrakinesis?" asked Harry.

"It is the ability to mentally generate and manipulate darkness, the absence of light." Hermoine recited. Mentally. Wandless Magic. And he looked barely fifteen. Harry hadn't seen his powers in action, but whatever it was, it didn't sound good.

Nico's POV

There were even more people around him the second time Nico woke up. All of them held out their sticks. What was this? Some kind of cult?

"Who are you?" One of them demanded.

Nico sighed. "None of your business. Who are you?"

His question was ignored. "Why did you attack this place."

Attack? Nico couldn't believe it. He had knocked politely, while they were the ones who attacked. Any move he made was to defend himself. He squirmed in his chair. Immediately, pain flooded his left arm. He looked down to see that the wound had reopened.

"I told you we should have healed him." A plump woman said. "We are not healing a death eater. Severus, give him the veritaserum." The weird-eyeball man countered.

"It'll be my pleasure," came the voice of a man with sallow skin and a large hooked nose. He had shoulder length black hair, and wore black robes. He was holding a vial of clear liquid. "What is that?"

"It is Veritaserum - a Truth Potion so powerful that three drops would have you spilling your innermost secrets everyone to hear" No, that was bad. He couldn't let anyone know of his heritage, especially not these people. Nico twisted his skull ring in nervousness, and three skeletons rose from the floor. He couldn't summon anymore than that. Only then, did he realise that in summoning the skeletons, he had exposed his heritage. He scolded himself for being so careless.

The strangers, using their sticks, managed to defeat all three of Nico's skeletons. This was the first time he actually got to see them fight properly. It was indeed like nothing he'd seen before. Different coloured jets of light flew out of their wands, as they shouted some word. It sounded vaguely like Latin, 'stupefy' sounding like 'stupeo', the word for stun.

All too soon, the skeletons were now reduced to bones, and Nico found his mouth being pried open. A few drops of the liquid was forced down his throat. It tasted no different from water.

"What is your name?"

"Nico...Nico Di Angelo." He had little or no control over what he said. Stupid truth serum. He sent a prayer to his father, hoping that he will forgive whatever he was going to say.

"What are you?"

"A ... half-blood." Nico could tell this wasn't the answer they were looking for.

"Do you work for Voldemort?"

"No? Who is that?" Nico's question was ignored again.

"So who do you work for?"

"Myself and sometimes my father."

"Who is your father?"

Nico struggled, but he couldn't help it. "Hades." None of them seemed to understand, and Nico was fine with that.

"How old are you?"

"Fift- Seventy five." Nico looked around to see many shocked, confused and sceptical faces.

"How do you know Necromancy and Umbrakinesis?"

"Self taught." Looks of horror filled the room.

"You do know that this is advanced dark magic that very few wizards know, and that it's is illegal, don't you?"

Nico raised his eyebrow. "Why, thank you." He looked at the confused faces around the room and sighed. This was going to take a long time.

"It's not a compliment!" The weird eye man growled. Nico smirked. "The way you said it made it sound like one. advanced dark magic, very few wizards know, remember?" Nico had clearly succeeded in angering the man. A lady with bright purple hair had to pull him back.

"Why did you come here?"

"No idea! I just wanted lunch at McDonalds!" He shouted. Out loud, it sounded a lot more ridiculous than it was. "I was on my way to lunch, then I got attacked by some dogs, and I shadow traveled to the wrong place, and now I'm tied up in this stupid chair because I wanted some food! Happy now?" Nobody responded. Perfect.

After a moment of silence, someone asked, "then why did you threaten Harry?"

"He holds the soul of Tom Marvelo Riddle, someone who should be dead." Another stunned silence followed. Nico was getting tired of this. "Now will someone untie me or do I have to do it myself." He said flatly. No one moved. Annoyed, Nico summoned some hellfire and burned though the ropes. He would have done it earlier, except he had only just regained enough strength to use his powers.

Standing up, he grabbed his sword and asked, "where's the bathroom." The first one to break out of their trance was the plump woman. She showed him to the bathroom and offered to heal his wounds. She took out her stick and said something, and the claw marks slowly faded. Nico was impressed, even if he didn't say so. Closing the door, he made a mist using the shower. Taking a spare drachma out of his pocket, he threw it in and said, "O Iris, goddess of the Rainbow, please accept my offering. Show me Percy at Camp Half Blood." Nico had considered calling Will, but he didn't know how he would explain to him.

Percy's face appeared in the mist. "Wha- Nico?" he said surprised. "Look, I've been sort of kidnaped. 12 grimmauld place in London. Long story, need to go, they are wizards."

Nico swiped across the mist, ending the connection just as the weird eye man burst in. "Who were you talking to?" He demanded, his glass eye looking around the room. "No one, and some privacy, please." Nico said quickly. "Fine. But if I catch you doing anything more, I'll make sure you are sent to Azkaban." He replied slamming the door.

Nico sighed in relief. That was a close one. He took a quick shower, and washed some blood off his clothes. He didn't really know why the truth serum hadn't worked anymore. He brushed it off, blaming it on the demigod immune system.

Afterwards, he was rushed off to spare bedroom and locked inside. Downstairs, shouts and banging sounds could be heard. Nico chuckled. They were probably discussing his fate. Nico wasn't worried, he should be able to escape soon. After eating some food that was slipped under his door, he tried to recall everything he could about Riddle's soul. If he remembered correctly, a part of his soul, in the form of a diary, was returned to the underworld a few years back. He also remembered the sheer amount of paperwork that came with it. Hades was in a bad mood for the whole week. At that time, Nico thought it was over, but now, he wasn't so sure. He reached out with his senses, looking for it. Surprisingly, the person, Harry, was only a few rooms away. Nico smiled. This was going to be easier than he thought.

All the adults were downstairs, in the meeting, leaving Nico with no one. That was their first mistake. Nico closed his eyes and focused on a spot at the other side of his room. As he expected, he managed to shadow travel there with no problem. He couldn't travel in and out of the house, but he could travel in it.

However, his sword had been taken from him again. That was a problem. He had no idea where it was being kept, and he didn't even think that they could hold it, but they somehow managed to. Must have been their magic. Luckily for Nico, he had an idea on how to claim that soul. He just hoped he would be able to do it in time. Wishing that he had brought some ambrosia with him, Nico slipped into the shadows.

Harry's POV

Something was happening. The shadows were all acting weird. They started to shift, all towards a corner in the room. Harry wasn't the only one to notice it. All of them were backing away from it. Harry remembered Hermoine's explanation about umbrakinesis. This certainly felt like it. Harry pulled out his wand. If he was going to face a death eater, he would need it.

Harry watched in fascinated horror as the boy from just now calmly stepped out of the shadows. The shadows receded and returned back to normal. This was the first time Harry had a good look at him. He was shorter than Harry, but that didn't stop him from looking intimidating. He had messy dark hair, a unnaturally pale complexion, and he was wearing all black- a black aviator jacket and dark jeans. He reached for something at his waist, but quickly stopped, as if remembering something. The boy was staring straight at Harry. "What do you want?" Harry demanded, hoping his voice didn't waver.

"You are harbouring the soul of Tom Marvelo Riddle, and I have come to collect it." He said darkly. Harry was confused. Voldemort's soul was in him? The boy was making no sense. Didn't he work for Voldemort?

"No! Harry is an enemy of You-Know-Who!" Hermione protested. The boy replied calmly, "then why does he have two souls in him? One of which, his enemy's?" He didn't seem fazed that there were six wands being pointed at him. Harry thought he was clearly mad. "Enough of this,time to get to business." The boy took a step forward. Harry's friends formed a protective ring around him.

However, before any of them could cast any spells, the temperature dropped to freezing, and the shadows rose. While they were distracted, the boy made a lunge towards Harry, and everything escalated.

Harry felt like he was traveling very fast, he didn't know what was happening, but this felt as bad as apparation. A spilt second later, Harry found himself in an empty room, still in the house. "It would be easier if you don't resist." The boy said.

"What are you doing to me?!" Harry shouted, hoping that the order members could hear him.

"Shut up!"he hissed. "Is it true you didn't know?" Harry nodded feebly. The boy muttered something in another language Harry didn't recognise. Whatever it was, it didn't sound nice.

"Scream." he said. "What?" Harry was getting more confused each second. "First you tell me to shut up, now you-"

"For Zeus' sake just do what I say!" The shadows surrounding them seemed to creep closer to Harry. Not wanting to anger the boy any more, Harry screamed. Immediately, he heard footsteps rushing towards their location. The boy grabbed his arm, and they appeared at the dining room, where the order had just left. Harry had to admit that was a smart move.

The boy picked up a sword that was as black as obsidian. "I'm going to try getting the soul out. I haven't tried this before, but it'll probably hurt. Try not to attract any attention." Harry didn't know whether to trust that boy. If a part of Voldemort's soul was indeed in him, it would be great if he could remove it. On the other hand, he didn't know where the boy's loyalties lay. He could very well be a death eater trying to kill him. Besides, the sword was intimidating.

However, Harry didn't have a choice. The boy pointed his sword at his forehead, and began chanting in the strange language. The shadows swirled around them. A piercing feeling shot through his scar. Harry clamped his hands on his forehead. He was tempted to scream, but no sound came out.The shadows around them were getting thicker, swirling faster. Worst of all, the pain wasn't subsiding, in fact, it was getting worse each second. Then suddenly, the pain disappeared. It felt as if it was sucked out of his body. His consciousness started to fade, and he saw the boy's face looming over him as he blacked out.

Nico's POV

Nico stumbled back, his sword falling out of his hand. It had worked. The soul was now out of Harry. That experience was nothing like Nico had ever done. He suspected he had some help from his father, as he really had no idea what he was doing. He said a quick prayer to Hades, and walked over to Harry. If it was even possible, Harry looked even weaker than Nico, and Nico was the one doing all the work!

Nico was weak, not as weak as Harry, but still worn out. He had indeed been using a lot of his powers lately. He smiled as he imagined how Will would react to this whole thing. Nico heard shouts and footsteps from the hallway. Looks like his little hiding spot was exposed. Nico didn't attempt to run away, and didn't resist when they shot spell at stunning spell at Nico.

I really need to stop waking up like this, Nico thought as he woke up for the third time. Once again, his hands were bound to a chair. He looked over to where Harry was still unconscious. He was still alive, just in a very deep sleep.

"I didn't harm him," Nico spoke up before anyone could say anything. "Well, maybe a bit, but he'll recover." Nine pairs of eyes all glared at him. This was going to be tough. It didn't help that Harry was unconscious, while Nico was more or less fine.

Holding out his stick, the weird eye man walked up to Nico. Pointing it at his chest, he said in an intimidating tone, "What did you do to him?"

"Nothing much, just removed Riddle's soul from him, did Harry a favour, returned a soul to the underworld, just the typical things I do. Oh yes, I also practiced unbrakinesis, necromancy, and a bunch of other things you find illegal." Nico was getting tired of their attitude. "Now, if you would kindly let me go, I have other more important things to attend to." The last part was a lie, unless if you counted dinner as important, which Nico kind of did.

The strangers around him remained speechless. That was the the plumbing exploded. Nico grinned. The calvary had arrived. The wizards tried to cast some spells, probably to dry themselves, but nothing seemed to work. The door opened and Percy strolled in."Hey! Heard you needed saving, Death Boy!"

"It's about time you arrived, Kelp head. What took you so long?"

"Did you forget I had to travel to London? Unlike you, I can't appear anywhere immediately. Besides, Blackjack wanted doughnuts so we had to detour around four times." Percy said, slicing riptide through the ropes that bound Nico. Rubbing his wrists, Nico stood up and grabbed his sword. "So, what do we do with these guys?" Percy asked with a glint in his eyes.

"Expelliarmus!" One of the wizards shouted. Percy brought up his sword to deflect it. Unlike Nico's blade, the red bolt of light was reflected back at the wizard, causing his wand to fly out of his hand. "Did I mention that they are a bit hot tempered?"Nico said with a smirk.

Percy laughed. "No idea how you survived through this. No I mean, how they survived without you losing you temper." Rolling his eyes, Nico said, "Trust me, I did."

"Wait! Surely we can work this out. Perhaps without the fighting?" A man with dark hair asked, before anything bad could happen.

After a while of negotiating, the demigods and wizards put away their weapons, and sat around the dining table. Harry had woken up, and seem fine apart from being slightly fazed. They began with introductions. Only then, did Nico notice that he only knew one of their names, and it was Harry's. They went in a circle, introducing themselves. Nico knew that everyone already knew who he was, but he still said, "Nico Di Angelo."

Nico and Percy went on to explain that they were demigods, and that Nico recognised Riddle's soul in Harry. He also said that it was normal for children of Hades to practice what they called 'dark arts'. Some of the wizards looked like they didn't fully believe them, which Nico totally didn't understand why. These people could also teleport and used sticks to battle for Zeus' sake. After Harry confirmed that he hadn't been harmed, the order decided to let them go back. Although, they did ask if the two demigods could stay to help with the war. Nico and Percy looked at each other. None of them were eager to be part of a third war. Nonetheless, they said that they would consider. Apologies were said, mostly to Nico, who grudgingly accepted.

Soon, Nico and Percy walked out of the front door, leaving the magical world and their problems behind. "How about McDonalds?" Percy asked.

Tell me what you think about it!

Not sure if I'm going to continue this story, where the demigods go help the wizarding world, or just leave it like this...

I'll see how this goes and thanks for reading!
