Yo readers! How'ya'all doing? Anyway I said I'll post the sequel, so there you go.

To all those who liked my story - 'Hadrian Potter: The Lightning Thief' - I want to say a big thank you to all of you. It was my motivation to write the sequel, because if I ever thought of abandoning this story-series my mind just filled with all the reviews telling me that this was a great story and that they can't wait for the sequel, and all the readers I would be disappointing if I did, and I just couldn't bring myself to do it.

Yes, yes, I know what you're all thinking - Enough with the philosophical and emotional thoughts, just get on with the story already!

Alright - onward to the story!

Disclaimer: If I owned Harry Potter, Sirius wouldn't have died. If I owned Percy Jackson, Luke would have never died but rather redeemed himself before his possession by Kronos at the end of Battle of the Labyrinth.

-Line Break-

His third year at Hogwarts was finally over.

After the welcome party he received, half of them fled when they finally realised that they were the prey. A consequence of that was the centaurs started referring to him for the forest matters. He was pretty much some all-powerful being to the forest animals. The unicorns treated him as though he was their king himself, which was odd since unicorns were known to be fast, powerful, innocent creatures which bowed to none. The centaurs told him of the burgeoning population of the acromantula colony (which Harry already knew about) which, while not as dire a situation as dementors, could create problems in the future. Apparently, it was Hagrid's responsibility to oversee the ecosystem of the forest and keep the balance. While the man had a big heart, in a more than literal way, he, like many others, saw only what he wanted to see. He was not going to take any action against his old friend's brood.

At Hogwarts, he learned why dementors were roaming around the school. Apparently, a prisoner named Sirius Black, who was supposed to be Voldie's right hand man, gone to Azkaban for killing a wizard and 12 muggles with a single spell, had escaped Azkaban, the prison the Dementors were supposed to guard, and the Ministry, in their infinite wisdom, placed them around school to protect him.

He also learned that this man was his supposed godfather, who had betrayed his parents somehow. No matter how hard he tried to find out, he couldn't find anything.

Another thing that happened was Dumbledore offering to take him on as an apprentice and him accepting. Dumbledore believed that it would be a good cover even though he would have offered it anyway considering Harry's talent, just not too soon.

Dumbledore was shocked to hear about Harry's parentage, as well as when Harry showed him his gifts from his mother.

He taught Harry the Patronus charm in case he had to fight them in the view of other wizards. They would not appreciate him fighting with a sword, bow, or whatever. Harry was very surprised to feel a similar power he had felt when meeting his mother when he showed him the spell. When he asked Dumbledore about it, he was not very surprised. After all, when a spell involved a silver coloured animal as guardian, it was not hard to connect the dots. Dumbledore told him that most of the old and powerful spells involved invoking the power of the deities. After all, Fiendfyre invoked the power of the Norse demon Surtur. As with every ability related to his godly mother, he was natural at it. His patronus was a unicorn and could pass as a real animal if not for the fact that it was glowing silver more than usual people's and it was completely white. The headmaster believed that his patronus could kill dementors.

He could fly again, so naturally they won the Quidditch Cup. Though the feel of his new Silverfly was better, he would never forget his Nimbus, his first broom.

Harry had told Ron and Hermione that he went to a summer camp in America, and when Hermione bombarded him with questions he told them it was a secret, and that Dumbledore knew it, and also that he had told him to keep it to himself. Thankfully, they had dropped it, saying that if Dumbledore said that, it must be really important.

He now took notes and typed essays on his laptop, which made it a whole lot easier. Of course, he had been again bombarded with questions on how it was working at Hogwarts and how did he get it, so he told them that it ran on pure magic, not electricity, so it was working at Hogwarts and that he got it from some 'relatives' in America that he didn't even know existed (he said the same for the broom). It wasn't a lie. Snape hadn't allowed Harry to use it in Potions so Harry simply just put the recording feature on and hid the laptop by shrinking it and then typed the notes listening to the recordings in his free time. He had also recorded each and every lecture, which had come very useful during examinations. His grades had skyrocketed comparatively, he wasn't as good as Hermione though.

As for choosing the electives, Harry took Ancient Runes and Arithmancy, the former because rune magic was very useful and powerful (also because he would have a head start, since they would be starting with Greek runes next year), and the latter because Arithmancy contained geomancy, which included creating magical maps (maps which changed according to the real place), which would come in handy for their plans for New Athens.

As it turned out, he was a natural at Arithmancy. Arithmancy was also nothing like he expected. It was kind of like the maths of the wizarding world. This year, they had worked with numerology, and the workings of spells. Kind of like computer programming. They would be given a query with a variety of magical symbols (of which they had to learn the various meanings and significance of, kind of like magical numbers in themselves) and thereby predict whether it would be possible or not, if so, what would it do, and if not, why? In fourth year, they would study the why of things, why the symbols representing the various things behaved in the manner they did as well as moving upwards to what Muggles would call real maths, calculus and other things. Including reducing spells into equations, they would also work with the laws of magic, its use, its limitations, its work, etc. Fifth year would be all about reducing magic and spells to equations, and they would learn working with equations to create their own spells, learning if the purpose of the spell was compatible with the equations, trying many different approaches, then translating them to the normal incantation and wand movements. A lot of them agreed that their O.W.L. year would be one in which they would be worked up quite a lot. Sixth year onwards, they would move on to the various branches of Arithmancy there were. Potions could also be explained by Arithmancy, and the magical properties of ingredients. But those came at a much, much higher level, like, those who wanted to go much further than a mastery into the subject. Basically, it was the maths and kind of physics of magic in one subject, Potions being the chemistry. Why so few in the wizarding world would choose such important a subject was beyond him (Why was it even optional?), but he wanted to be in the few who did.

Anyway so, back to topic, Harry was a natural at Arithmancy. It was the first thing he even surpassed Hermione at, about which she was still a little miffed. He had easily aced the classes, and the exams, with flying colours. Professor Vector praised him thoroughly and looked quite pleased. 'It's not everyday you meet someone with a talent for Arithmancy, quite the opposite in fact.' Her words, not his. She asked if he had any schooling in Muggle subjects of Computer Science and Maths, to which he responded in negative. Astonishingly, she looked even more pleased, and told him he was simply a natural, and also that he should try, if he had any interest in Arithmancy, he would no doubt find it interesting too. He said to her he would certainly try, and resolved to try later on his laptop.

When he returned to school after Winter vacation, he noticed a lot of changes, primary being the absence of dementors. And that Professor Lupin had been replaced as an Auror after Sirius Black was sighted within Hogsmeade. He was pretty miffed about that, since the Professor was their best DADA teacher till now.

Later, Ron was kidnapped. He asked for details and was about to go to the Whomping Willow when he found out but the Auror who became their DADA professor, stopped him (though Harry was insistent at first, and had snapped at him) and went to rescue him himself. When he got there he found not only Sirius Black but also Peter Pettigrew, the wizard who Black was sent to prison for killing, very much alive and well. Both of them were taken into custody. There were many other tales mentioning forbidden love or something that he ignored. He asked Dumbledore about it but he asked him to wait until he had all the facts.

The next surprising incident was him getting an invitation to Azkaban. Yes, you heard it. Apparently, somebody (a certain twinkle-eyed old man cough), informed them that his Patronus was special and could kill dementors. Dumbledore escorted him there naturally.

Azkaban was a dreary place, fitting for its monstrous guards. Or perhaps the long term presence of the dementors turned the place that way, he didn't know. The very earth there seemed to be blackened by the unnaturalness, the misery, the pain. The castle itself, which seemed to be made of pitch black obsidian stone, stood stretching to the sky towering over everything else like Dracula's castle brought to life.

From what Harry could see, nobody liked dementors, not the Aurors, not the politicians, not the 'Imperius Curse' victims, perhaps not even old Moldyshorts (his new nickname for Voldie) himself. The Aurors they met seemed skeptical. Perhaps, they might not have even allowed him there if he had not been Dumbledore's apprentice. He could not blame them. From what he understood, they were the ones doing the guard duty here. While they had the talismans, it only provided the protection of a beginner level Patronus, some silver mist thing which diminished the effect of the dementors but could not chase them away like proper animal guardians. It was disconcerting to see that most of the Aurors were wearing a talisman, a stark realisation of how few people could cast the spell that came naturally to him.

They were led to the room where they had the dementors trapped. On the way, we met many different kinds of people: reporters, politicians, 'concerned citizens'. One interesting person he met was Amelia Bones, the new head of Department of Magical Law Enforcement (DMLE). She was slightly chubby but he could tell it was the kind that came for those who were used to a physically demanding lifestyle and suddenly ended up in a desk job, unlike her niece who was, let's say, slightly spoiled. By the way she held herself, he could tell that she was as dangerous as she used to be when she was more active. From the way, she scrutinised him, he knew she saw that there was more to him than his unimpressive exterior might suggest.

In the room, two Aurors were keeping the dementors back with their Patronus. By how dark the room was, he knew that they had every dementor they knew about in there. He requested them to let go and they did after they got the nod of consent from their boss.

The dementors charged him enmasse but he wasn't exactly scared. They knew that he could kill them.

When they got close enough, he pointed his wand at them and spoke the incantation. A huge silver unicorn burst from his wand. As expected, it was a massacre.

Soon, the Easter holidays came and he got a visitor, a very much innocent Sirius. Fudge had an interesting story for the Daily Prophet. Apparently, after Black's breakout, Minister Fudge found some inconsistencies in the case and ordered an investigation into it that he personally oversaw (*cough* Yeah right. More like he did it to safeguard the Ministry's and his own reputation and position after questioning Peter Pettigrew and finding Sirius innocent). Many evidences were found that showed many of the previous ministry being less than honest. The present Minister naturally took the steps to correct the mistakes of the previous administration and see that justice was done. The Minister awarded Black 100000 galleon for every year of his incarceration and the fees for being unregistered animagus was waved away as wartime concessions with the former claiming that the latter would have registered had he had the chance to do so. The Prophet also stated that Sirius Black would soon be taking over as the head of House Black.

Sirius told him the tale of four boys who became friends at the beginning of their school life and together formed a group of mischief makers called Marauders. He also told him of the three of them who chose to become animagus to accompany their werewolf friend on full moon nights along with their nicknames (Moony a.k.a. Remus Lupin, Wormtail a.k.a. Peter Pettigrew, Padfoot a.k.a. Sirius Black, and Prongs a.k.a. James Potter). He then heard about the pranks they played on each other and the others. He then told him about my father's incessant attempts to woo his mortal mother and their comical failures. Even if he was content knowing that they were having a happy afterlife, probably in Elysium, he was glad to have had a chance to understand them.

Sirius then shockingly told him that he knew about his birth circumstances and how his mother became infertile and about his immortal mother.

In the middle of one such tale that Sirius was telling him, they were greeted by the Weasley twins who overheard the keyword 'Padfoot' and asked if it had anything to do with 'Moony, Wormtail, Padfoot and Prongs'. When Sirius asked them how did they knew about that, very suspiciously mind you, they showed him a map called the Marauders' Map, which was basically a magical map of Hogwarts, along with showing at which particular place at Hogwarts a person was in the form of an indicating dot with the said person's name on top of his or her respective dot. Also, it appeared and disappeared by saying weird phrases. You had to say 'I solemnly swear that I am up to no good' to make it appear and 'Mischief managed' to make it disappear. Sirius was very ecstatic to see the map. He told the Weasley twins about the Marauders. They immediately started bowing to and thanking him. They gave the map to Harry saying that they had already memorized all of it and that it was his by 'birthright'.

Harry asked Sirius if he had the research notes on making the map. Sirius answered him by telling him that they hid them in a secret room in Potter Manor. He asked him why. Thankfully, he already knew about the gods, so Harry explained to him about camp. He told him about how it would considerably improve the security of camp. He also told him about the plans for New Athens and he agreed that it would prove to be a help and promised to bring them from Potter Manor if he found them.

Soon, the story turned to a darker path with them fighting on the frontlines. Sirius talked about families like McKinnon which had ended, Harry's mortal grandparents' death during an attack on the family mansion and many other families on their last legs. He told him about his parents deciding to stay under the Fidelius charm placed on an old property nobody knew Dumbledore owned and a brief description of the charm. Apparently, it was an extremely powerful protection charm embodying the concept of trust (in someone else). Sirius convinced his parents to use Peter Pettigrew as the Secret Keeper while he served as the decoy to fool the traitor amongst them never knowing that Pettigrew was the traitor who would hand over the secret to his master. He only realised the truth when he visited Pettigrew's house and saw funeral clothes and speech prepared. By the time he rushed to Godric Hollow, everything was already over. After he made sure he was safe, he went after Pettigrew who outsmarted and framed him. It was followed by a series of regrets and apologies Harry was glad to get it over with. There was only so much angst he could take. As for Peter Pettigrew, his only regret was that he killed off the dementors too soon and he would not be getting the full Azkaban experience.

Sirius then asked him if he wanted to live with him. Harry told him that while he would love having a fun loving uncle spoiling him rotten, he felt comfortable at camp. Sirius then told him that as now he was the Head of House Black, he was accessible to all properties of House Black, and so he would be able to move to America. So he asked if Harry would be able see him occasionally in the summer. Harry agreed to that.

Soon the meeting ended and Harry was back in his normal routine for the rest of the days before summer. About two weeks before the exams, he started to study and listen to all the lectures of the year. He did considerably better than the last two years.

The last surprise he got was from Dumbledore. He called him in his office on the morning of leaving, to give him his portkey. However, he found Neville Longbottom sitting inside the Headmaster's office. Dumbledore told him that Neville was a half-blood as well and would be going to Camp Half-Blood with him. Dumbledore was doing the work of satyr at Hogwarts. Harry had a very likely choice for Neville's godly parent, if his love for Herbology and kind nature was any indication. Dumbledore shrunk both of their trunks, bid them goodbye, and gave them the portkey. A few seconds later they vanished from the Headmaster's office.

-Line Break-

They landed at the bottom of Half-Blood Hill with Harry again landing flat on his face.

He got up and looked at Neville. He had managed to stay on his feet, even if he looked a little dizzy. Most of all, he looked nervous.

"You're going to be fine, Nev," Harry told him. Neville smiled at him.

They made their way together to the top of Half-Blood Hill. What Harry saw there made him do a double take.

Its needles were yellow. A huge pile of dead ones littered its base. In the center of its trunk, three feet from the ground, was a puncture mark the size of a bullet hole, oozing green sap. A familiar green sap, from his mother's lessons.

Someone had poisoned Thalia's Tree.

-Line Break-

Harry was sitting at the Artemis table, not feeling like eating. Who would? Chiron was gone. Fired. Apparently, someone had to take the blame for Thalia's tree poisoning. The tree was poisoned with the blood of the Python, taken from the depths of Tartarus. There was no known cure. Except one. But the thing was lost years ago. This meant that unless they saved the tree before it was too late, the tree would obviously die, but once it did, the magical borders of camp would fail as well as all the vegetation of the camp. The woods, the strawberry fields, the grass and weeds, each and every plant.

In Chiron's place as the camp's activities director there was a world-class jerk known as Tantalus. He hated all the demigods, but seemed to like Clarisse for some reason.

He had just announced that they were going to reinstitute the chariot races, completely ignoring a fact pointed out by someone at the Apollo table that the races were discontinued in the past due to three deaths and twenty-six mutilations and passing them off as 'technical problems'.

If Harry had any doubts before, all had vanished now and he was quite sure that this guy was off his rocker. But then again, this was the guy who had tried to feed his own childrento the gods.

Percy had come to camp the same day along with Annabeth, and they had brought a Cyclops with them. Tantalus was currently taunting Percy about it and was making jabs at where on where Tyson (the Cyclops) would sleep or what would be his fate. Then the whole camp gasped. Above Tyson was a swirling green trident.

Then there was Neville. He was very nervous. Before dinner, Harry had to assure him several times that he would be fine to calm his nerves.

Mr. D got up from the Dionysus table. "Well, well, I suppose I must say it. Welcome back. Also, we have a new camper today. Nevin Longhurst." Neville protested from the Hermes table about his name, but Mr. D ignored him. "Now, run along to your silly campfire. Go on."

Everyone made their way to the campfire, murmuring and some shooting nervous glances at Tyson. Neville immediately came over to Harry's side as they walked. Harry inwardly sighed. He would have to work on Neville's confidence.

The camp fire wasn't burning as high and bright as it usually did, as the campers' mood was gloomy and grim. They roasted smores, but not with the same usual enthusiasm. Tantalus was enjoying every moment of the camp's misery, as it seemed.

It took all of Harry's willpower not to snap at him.

Just as the sing along ended, a sign glowed above Neville's head. Huh. It seemed as though Harry's guess for his parentage was correct. He was glad that Neville wouldn't have to sleep in the overly-packed Hermes Cabin.

Above Neville was a golden sickle (not the wizarding coin, the harvesting tool, thank you very much) with a few sheaths of wheat. All the campers bowed. Harry did so too. He waited for words, like the ones Chiron had given, at his and Percy's claiming. When none came, he looked up. He wasn't the only one.

Harry's dislike for Tantalus heightened as high as Olympus when he, instead of following tradition, said, "Yes, well, so we have a place to put the new brat in. Now move along, to your little cabins. And take the brat to his new cabin." Nobody moved.

Harry looked at his friends. Percy looked furious. Harry could only imagine what it must be for Percy to keep his anger under control. After all, the sea does not like to be restrained, Percy had told him last summer in one of their playful spars against each other.

He was pretty angry himself, not only did the jerk not care for camp, but had the nerve to disrespect two Olympians in one night.

Annabeth was very angry, you could see it in her stormy-grey eyes.

Apart from all that, almost all the campers were angry (he wasn't sure about the Ares cabin) but Demeter's cabin looked murderous at Tantalus for disrespecting their mother.

As for Neville himself, he looked confused as he looked curiously at the now fading symbol above his head.

Katie Gardner, the head counselor of Demeter's cabin, stepped forward, and, all of a sudden, Tantalus yelped. Harry looked over to see him get grabbed by a few vines and thrown in the direction of the Big House. The members of cabin four had satisfied smirks on their faces. If Harry had ever underestimated the Demeter Cabin before, he sure as hell wasn't going to do so in the future.

Katie coughed loudly over the snickers and cheers of all the campers. All of them turned to look at her. "Hail Neville Longbottom, son of Demeter, Goddess of Agriculture, Grain, Harvest, Growth, and Nourishment." The campers all bowed. Harry realised that when the ones they respected and cared for were threatened, harmed, or killed, Demeter's children could be ruthless, rather than the calm, peaceful demeanor they always carried, the one which led to them being underestimated.

Neville looked at Harry, and Harry allowed him a smile. After that, Harry was going to lead Neville to the Demeter cabin, when his siblings came and took him with them. Harry accompained them nevertheless, and waved and bid Neville goodnight, telling him he would see him in the morning as they reached the Cabin Four.

After that, he left for his own cabin and once inside, made a straight bee-line for the usual spot by the creek where his tent stood. He got inside his sleeping bag, gazing out into the stars, spotting constellations, reflecting on and thinking about past events, Thalia's Tree poisoning, Tantalus the world-class jerk being the new activities director, chariot-races being reinstituted, campers abandoning every chore to work on their chariots, even border patrol, which was heavily needed right now…

He fell asleep, drifting into his own thoughts.

-Line Break-

He was standing, sword in hand, wearing armour, in what seemed, to be the ruins of some place. Smoke drifted up from some, a lot of people he vaguely recognized by his side, fighting monsters. The whole place seemed to be overrun by monsters.

Only when his eyes landed on a particular tree in distance, very close to its death, did he realize which place the ruins were of. The place where he had felt truly at home. The place that gave him a sense of true belonging, for the first time in his life. Camp Half-Blood.

Face it,little hero, a voice which chilled his blood to bone echoed from the bottom of the earth in the distance, this is not a dream. This is the future. One day, this will turn to reality. You can only delay the inevitable.

The voice laughed cruelly, it's laugh even more cold than it's voice. The ground cracked, and he cried out as he fell and fell and kept falling into endless darkness listening to the high, cruel, cold laughter…

-Line Break-

Harry woke with a start. For a moment he was sure he was falling, but then realized it was a dream. He remembered the voice, and had a pretty good idea of who it belonged to…

The voice had said this was the future.

No, he vowed to himself, that won't happen. I won't let it happen.

He lay back in the sleeping bag and drifted off to sleep some time later.

-Line Break-

So. Like it? Dislike it? How was it?

There we go. I said I'll post a sequel, so here is the first chapter. I hope you liked it!

Also, any suggestions, feel free to PM me, or give them by reviews.

Bye readers! Please R & R.
