A/N: I am absolutely, dreadfully sorry. Please don't hurt me. In my defence, though, I had a LOT going on. Model UN (WMIDMUN XIV! Shout out to all of y'all who went, if you're reading this.), a Commonwealth Governor's School application, projects, school, softball, then I was introduced to Supernatural.

I got into CGS, by the way. I am quite proud of myself. But just a warning, next school year, I am going to have a lot on my plate academically. I'll do my level best to not go on any spontaneous hiatuses without warning at least. That was rather unfair of me on my part.

Note on the timeline: Everything in HOO happened a month earlier. So the final battle occurred on July 1st, not August 1st.


Percy Jackson's POV

Percy was tired. There was no other word for the pure physical, emotional, and mental exhaustion he felt.

Two wars, one right after the other. So many deaths. Leo died yesterday, along with many, many other demigods. Camp Half-Blood was in ruins. Just a few weeks ago, he and Annabeth returned from Tartarus, for Zeus's sake! Now this…this wizardly side of the family? Which is also, not to mention, in a war of their own? Can't the Fates cut him some slack for once?

Why couldn't his brother have come from a family of bankers? Nice, normal, not-part-of-a-magical-war bankers?

Why?

Sighing dejectedly, he looked up at his mother, his amazing mom who put up with so much, and said, "Hmm?"

"What did you mean by 'Leo's thing is tonight'?"

With a lump in his throat, he looked at his beautiful Wise Girl, the silent request on his face. She answered the question for him. Her voice thick with emotion, "Leo's dead. He died yesterday afternoon. He died saving us all. The funeral is tonight."

Sally put a hand to her mouth. "Oh my gods…he was such a good kid, I can't believe it, oh, I'm so, so sorry." She then pulled them into her arms, and Percy buried his head in his mom's shoulder. Sure, she wasn't his birth mom, but they loved each other all the same.

A couple moments later, he looked up to a sympathetic Paul and a vaguely uncomfortable-looking Severus. "We should get going."

~~~LGEMC~~~

The car ride was quiet. There wasn't a whole lot to say; his godfather knew his numerous questions were going to be answered at this mysterious "camp," and his mom was going to find what had happened soon enough. Most of it, anyway. Percy didn't want his mom burdened by the knowledge that her son and girlfriend had gone through Hell and met the Greek and Roman equivalent of the Devil incarnate, AKA Tartarus.

The car slowed to a stop near Half-Blood Hill. Annabeth, his mother, and he could see Camp, but he didn't know about his newfound godfather. Judging by the raised eyebrows, apparently he could.

Severus looked at Percy, silent request for an explanation apparent on his face.

"This is Camp Half-Blood, one of two places is the world that is truly safe for my and Annabeth's people. And it was a war zone until yesterday afternoon." He told Severus, sadness filling his voice during the last sentence. "And just a reminder, please be careful and stick with one of us; we're all on edge here."

The foursome trudged into Camp, heading towards the Big House. Severus was looking all around with wide eyes; at the busy infirmary, the Roman encampment, the ruined pavilion. It broke Percy's heart to see his home looking so war-torn.

Then he saw Jason on the porch of the Big House with Piper. He waved them over. "Hey, Percy, Annabeth, Aunt Sally. Nice as it is to see you though, who is this guy? I don't recognize him." The son of Jupiter asked.

"That's why he's here. I need you and Piper to round up Chiron, the cabin leaders, Thalia, Grover, Reyna, Frank, and anybody else of importance. Bring them to the ping-pong room."

Jason whistled. "Wow, that important, huh? I'll go get them. Chiron's in the Big House with Poseidon, he came by looking for you."

"Thanks for telling me- we have a lot to talk about."

They looked at each other, knowing that gods don't just drop by without a good reason.

"I imagine this pertains to the sudden gathering of important people?"

"You bet. Life just got even more complicated."

Once the couple walked off, they found Chiron and Poseidon in the Big House's living room. Chiron smiled warmly, but Poseidon paled considerably at the sight of Severus. He had recognized the wizard, and knew the implications. "Hello, my son. And it's good to see you again, Severus. You must have finally found my letter at last." Despite his father's new pale complexion, his voice had held strong.

Annabeth spoke up. "Now, I'm sure you have plenty of questions, but they can wait until everybody gets here. Then we can explain the magically charged mortal in the room."

Chiron and Poseidon both started talking at once.

"You're going to tell them about the wizarding world?!"

"Wait- that man's a wizard? What's he doing in Camp Half-Blood?"

"That is unwise course of action- you've been kept in the dark for a reason!"

"How do he and Lord Poseidon know each other?"

Percy made placating gestures. "Chiron, we'll explain when everybody gets here. Dad, yes we are going to tell them. My brother, who I didn't know existed until today, is a demigod. People are going to ask questions about where's he's been. And my godfather has a right to know why his godson is covered in scars and has PTSD." That shut up Poseidon, and left Chiron speechless and flabbergasted- now that was something you didn't see every day.

Severus looked as if he was going to say something, then thought better of it.

A rather tense five minutes later, Clarisse, Reyna, Frank, Hazel, the Stolls, Katie, Will, Nico, Grover, Nyssa, Thalia, Rachael, and an out of breath Jason and Piper filed into the Big House. Everybody crammed around the ping-pong table, pulling up extra chairs for Sally, Severus, and the praetors. Poseidon took Mr. D's usual chair.

Reyna, looking intimidating as ever, levelled a stare at Percy. "Percy, why have you gathered us here? Who are the two mortals?"

Percy held Annabeth's hand under the table, and took a deep breath. "For those of you who don't know, the woman is Sally Jackson, my adoptive mother. For those of you who do know, hold your questions until the end. The man is Severus Snape, my godfather. I'll tell you what he told me this afternoon.

"There are wizards in this world. In Great Britain, some thirty years ago, the equivalent of a wizard terrorist, rose to power. He believed in the superiority of purebloods, wizards who come from all-magical families. His name was Voldemort, and his followers were called Death Eaters-"

At this, the whole table was in laughter, minus Poseidon and Chiron, although the latter had a small smile. Nico was laughing the hardest, before coming to some sort of realization.

Admittedly, Voldemort was a ridiculous name and sounded a lot like "Mouldy Shorts."

Once the laughter died down, Nico spoke in a quiet and angry voice, "I know who that is. And my father and I are very, very, irritated by him. He is the epitome of evil- splitting his soul into pieces, and torturing innocent people to death and madness. Hades has a special place in the Fields of Punishment for when Tom Marvolo Riddle finally dies."

If Severus wasn't curious before, he certainly was now.

"I am not surprised, Neeks." Percy said. "Anyway, there was a group dedicated to fighting the Dark Lord, called the Order of the Phoenix. Seventeen years ago, one of its members, Felicia Potter, gave birth." Some of the teens' and Chiron's eyes grew wide as he saw where this was going. "That baby was me. Two years later, she gave birth again, to my younger brother. Poseidon is still the father, in case you were wondering. And of course, there was a prophecy. It seems bad luck is in our blood- there was prophecy, saying that a child born as the seventh month dies will have the power to destroy the Dark Lord. My brother, Harry Potter, was born on July 31, and is the subject of that prophecy. Long story short, Death Eaters killed Felicia, Dad took Harry to my Uncle James and his wife, Lily, and me to Sally Jackson in New York. He split us up for our protection. A year later, the head honcho himself came and killed James and Lily, tried to kill Harry. The spell bounced back, however, and the Dark Lord's body died, but a piece of his soul lived on.

"Of course, Harry has the legendary demigod bad luck. This past June, during and international tournament at Harry's school, a rigged trophy transported him and a classmate of his to an unknown location, where his classmate was murdered and Harry's blood was used to give Voldemort's soul a body again. The Dark Lord has risen. Even more unfortunately, the Ministry of Magic denies this fact."

Silence greeted the end of the story. Many looked at Poseidon with shock on their faces.

"Okay! Any questions?" Percy said in contradicting bright manner.

Reyna, Frank, and Chiron looked at each other, a silent message passing between them. Reyna stood, looking at Severus. He was the representative of the wizarding world. "Severus Snape, if you are expecting us to fight in your war against your Lord Voldemort, we will not. Every single one of us is a war veteran. Most of us are two-time war veterans. Yesterday afternoon, we won a war. We had just begun to recover from last summer's war when we were thrust into another one. We must bury our dead, and I can say with fair certainty that every single demigod in this room has PTSD. We will not fight in your war, not unless is becomes our problem." She then stared at the wizard defiantly, with her jaw set.

After a moment, he replied in an assertive voice. "I don't know why teenagers would be fighting in wars, and I find the very idea repulsive. I would never in a million years ask you to fight in this war. I came to New York looking for my godson, who everyone thought dead after his mother Felicia was murdered. Only recently did I find out, after a letter written by Poseidon was found in a journal of Felicia's.

"Now can somebody please explain to me who you are?" He demanded.

There were many expressions of relief. They wouldn't have to go to war again.

Everybody looked to Percy to explain the demigod world to Severus. Sighing, he said "Do I have to?" in an overly dramatic voice. An intense debate between the campers followed as to who would explain what. It ended with Percy explaining that the gods were real, then Nico and Reyna take turns telling the story of the Second Titan and Giant Wars. The short version.

After several pointed looks and hushed whispers, Nico, Reyna, Percy and Annabeth decided to leave out the trips to Tartarus. Percy really, really did not want his mom and godfather to know about that particular venture.

Percy turned to Severus, already in full-on counsellor mode, the kind he used on new campers. "Severus, have you heard of the Greek and Roman gods?"

"Yes." His godfather's voice betrayed no emotion.

"They're real. You're going to deny it, but they're very much real. Everything from Greek and Roman mythology is real. Even the Underworld. In the ancient days, gods went around Earth having kids. They're still doing that. Every teenager in this room is a demigod, except Grover. He's a satyr." Said satyr put his hooves on the table, only for Hazel to scold him.

Percy's first impression of Severus was a man not easily flustered. This proved to be correct. He was taking the whole gods-are-real thing very well. Most new campers break down, called them crazy, and so on. Severus just stared at him for a solid minute. Percy could see the inner turmoil in his eyes, the denial. Then acceptance. "I'm skeptical, but I believe you." Sighs of relief all around. "That still doesn't explain everything else."

Percy winced. This should be fun, he thought sarcastically.

Reyna Ramírez-Arellano

This morning, prior to the Wizard Revelation

Reyna was ready to collapse. Too much had happened far too quickly. Shadow traveling across the world, then the battle, then staying up all night running around, helping the medics, catching up on matters she missed while fetching the Athena Parthenos, and handling the aftermath of Octavian's temporary rule over Camp.

It was a wonder she hadn't passed out yet. Her stomach growled, reminding her to eat. When was the last time she ate? Reyna couldn't be bothered to remember. She dropped off the fresh bandages and unicorn drought from the supply tent at the infirmary. Then she made her way over to the dining pavilion at Camp Half-Blood. Just as she sat down with some grilled cheese and soup, someone tapped her on the shoulder.

Jumping up and turning around, she glared at whoever dared to disturb her. She was cranky when exhausted. She relaxed when she saw that it was just a Roman messenger.

"Praetor, the eagles just brought this in from Camp. It's from the medic in charge of the Camp's medical facilities."

"Thank you, I'll look at it while I eat." She smiled in thanks at the messenger, who then went to get their own breakfast.

Sitting back down, she opened the letter. Why would Amanda, the Camp's chief medic, send this letter to her, instead of the chief field medic?

Praetor Reyna,

Three days ago, a seventeen year old boy appeared on the camp's borders, wearing torn and dirty yellow and black clothes. They were like some kind of uniform. He was clutching an unusual stick in his hand. We took him back to the camp infirmary, where he woke up the next morning.

He identified himself as Cedric Diggory, and as a British wizard. A wizard! We thought he was crazy, until he performed some spells, lifting a pillow and even a food tray with a word and flick of that stick, which turned out to be his wand. Then he demanded to know where he was, and who we were.

We didn't know what to tell him, so we told him the truth. Maybe we could form an alliance with these wizards? He took the news pretty calmly, all things considered. He responded with, "Well, if wizards are real, then gods and demigods aren't so much of a stretch. We both shouldn't exist."

The more troubling matters are the ones that brought him here. Diggory told us that he was participating in an international school event, called the Triwizard tournament. During the third task, both he and a boy named Harry Potter grabbed the trophy at the same time (this because both he and Potter thought the other should win, and came to the compromise that they would both take it) and were transported to a graveyard. Here, Diggory was hit by a green spell, known as the Killing Curse. This curse, according to Diggory, is one of the three Unforgivable Curses, expressly forbidden.

Cedric Diggory died that day. Our theory is that he came back life before the Doors of Death were shut, and before Thanatos was freed, since he's still here.

Amelia M. Daniels

Chief Medical Officer of Camp Jupiter

Third Cohort, Daughter of Apollo

Reyna sighed and rubbed her forehead. Looks like that nap would have to wait. The world just grew tenfold again. She's not even surprised by this stuff anymore. Finishing the last of her breakfast, she stood up, only to be confronted by Jason Grace and Piper McLean.

"Reyna! Percy and Annabeth are back from the city, and they've called a war council meeting- all the important people need to be there. Percy brought his mom too. Something big is going down." Jason said between pants.

"Hi, Reyna. Did you sleep at all last night? You look exhausted." Piper said, sympathetic.

"Not a wink. How about you? And this better be important, because I just got a letter from Camp that requires immediate attention. Huge problem. Where's Frank?"

Raised eyebrows from the couple. Jason spoke first. "Percy and Annabeth seemed pretty serious about this. You can announce this problem at the meeting, and we were going to get Frank after we found you. Wait, never mind. He just walked into the pavilion. He's walking over here-"

The son of Mars clapped Jason on the shoulder and smiled tiredly at the trio. "Hey guys. I don't know about you, but I am dead on my feet."

Reyna smiled back. "Same here. Listen, Percy and Annabeth have called a war council meeting. Everybody who's somebody. I also got a letter from camp, and we all have a huge problem on our hands."

Piper and Jason left, and the two praetors began the walk to the Big House.

~~~LGEMC~~~

Present time, after Percy explains the basics of the Greek/Roman pantheon.

Nico went first. "Seventy-five years ago, the current Oracle of Delphi gave a prophecy, tell how a demigod child of the eldest gods would make a choice that would either destroy Olympus or save it. It was believed that the eldest gods referred to Zeus, Poseidon, and Hades. They swore an oath to never have any more kids. Zeus and Poseidon broke their oaths- evidenced by Thalia, Jason, and Percy. Hazel and I are from the forties. Five years ago, the Titan Kronos began stirring. He turned some demigods against Olympus, taking advantage of their anger towards their godly parents. Luke Castellan was the first. He became the general of Kronos' army of demigods and monsters. Many battles later, everything climaxed last summer. Percy was thought to be the demigod mentioned in the prophecy, and led Camp Half-Blood into battle when Kronos' army invaded Manhattan. Mount Olympus floats above the Empire State Building. This happened on Percy's sixteenth birthday. The gods had to go fight an ancient and powerful monster, Typhon, who was raging his way through Missouri at the time. Luke had become the vessel for the spirit of Kronos.

"Percy fought Kronos himself, while Jason fought the Titan Krios. The Romans were waging their own battle that day. In the end, Percy, Annabeth, and Kronos were in the ruins of the gods' throne room on Olympus. Annabeth coaxed Luke back into his own mind, and then Luke killed himself, before Kronos could return to his true form, where he would unstoppable.

"Many, many, demigods died that day. Not one over the age of twenty-five."

Reyna saw that Thalia's jaw was clenched, and Annabeth's head was buried in Percy's shoulder. She had heard about how closed the two had been to Luke before they all came to Camp Half-Blood. Hearing about all of that must have dredged up painful memories; plus the added emotional vulnerability that came from a war ending only yesterday. (Not even twenty-four hours ago!)

Reyna let that sink in for a moment. Then she cleared her throat and told of the Second Giant war. Of how Hera kidnapped Percy and Jason, then how the goddess was kidnapped herself. Of how Percy, Frank, and Hazel went to Alaska, kill a Giant, and brought back the Legion's eagle. And the quest for the Athena Parthenos. How Percy and Annabeth's "Unintended solo mission to close the Doors of Death." How Nico nearly killed himself getting the statue back to Camp in time to prevent the Greeks and Romans killing themselves. And ending with Leo's sacrifice. "…while Jason kept Gaea aloft, Piper used her charmspeak to sedate her, and then Leo atomized her, and himself. And then it was all over."

She gave very little detail.

This was very recent, and a raw emotional wound, after all. It would only do harm to go on about it.

The war only just ended yesterday.

Yesterday.

Shaking her head, she stopped that line of thought. Now was not the time to have a breakdown.

Now for the difficult part. Explaining how a dead teenage British wizard showed up at Camp Jupiter.

"Severus, this morning a received a letter from the Chief Medical Officer of Camp Jupiter. She told me a British teenage wizard, Cedric Diggory, showed up at Camp three days ago. Based on his story, he died before Thanatos was freed and the Doors were shut. I believe he was the student that was killed in the Tournament."

Just like ripping off a Band-Aid. No beating around the bush.

Severus stared at her with that truly fantastic poker face of his. (She'd have to ask him what his story was- one doesn't learn a poker face like that by living an apple-pie, white picket fence kind of life. Perhaps it was something to do with the war against this Lord Voldemort Percy mentioned earlier.)

And kept staring. If he stared like that any longer, Reyna might just think they actually shocked him.

Reyna felt the air ripple and become charged with a mysterious energy. Hazy white tendrils of the Mist snaked throughout the room, emanating from the space behind Severus. The demigods looked around with wariness and confusion. She rested a hand on the hilt of her sword. What was causing this?

The white Mist condensed behind Severus, then glowed a soft green. A woman appeared. She was tall, with ebony hair spilling to her shoulders in soft waves. She wore white robes, covered in silver swirls and black runes. She radiated pure power.

A goddess, then. Recalling Hazel's account of Hecate, how the Mist gathered in her presence, that this must be her.

"Hekate*. What brings you here?" Poseidon greeted, neither friendly nor threatening.

She smiled at him, appearing friendly yet guarded. "Oh, many things. I come to see my children, they did just win a war yesterday afternoon. I also come since one of my people has encountered the Greco-Roman pantheon in unprecedented ways."

Severus looked indignant at the "one of my people" comment. "One of your people? What right do you have to say that?"

Reyna winced. He obviously had no clue who he was speaking to. Gods have smote people for less disrespectful behaviours before.

"I realize not all of you know who I am. Because of this, I will let your disrespect slide. I am Hekate, Trivia to the Romans. The Goddess of the Mist, Magic, Crossroads, and Ghosts. Roughly two thousand years ago, I blessed a group a group of humans with magic. They have grown into the global subculture you know today. Sometimes I bless normal children with magic at birth; they are the Muggle-borns. The wizards are my people. The fact that I am also a goddess of ghosts means that I am responsible for sending my dead to the Underworld, which is why Thanatos did not collect Cedric Diggory after he was freed."

"Another little known fact is that all demigods are capable of wielding the same brand of magic as wizards. This is due to their divine blood." Then she smiled a bit at the demigods. "So if Percy decides to go to Hogwarts, then you could go with him."

"Oh, and before I go see my children: The situation with Tom Riddle has been escalating, and he is delving into matters he shouldn't be." And with that, she turned and walked out of the war room.

A contemplative silence filled the air after the goddess left.

Percy Jackson's POV

Percy did not like rehashing the two wars he had survived. Dredging up old memories of the Second Titan War, on top of the past several months, including yesterday? Trying to be optimistic, he focused on the fact that Tartarus was artfully left out of the conversation. "Unintended solo mission to close the Doors of Death" was one way to put his and Annabeth's vacation to the Pit. An unintended shudder passed through him as memories of controlling poison and endless armies of monsters washed over him. Annabeth's head came to rest on his shoulder, grounding Percy in the here and now, as if she knew what he was thinking.

Here and now- there was more pressing matters at hand. Hecate had said "If Percy goes to Hogwarts." He didn't know about magic school, but he definitely wanted to meet his brother- and find out where he's been living when not at school. Severus didn't know, but if his godfather's suspicions were right, then it wasn't anywhere good.

They had a lot to talk about before meeting his brother.

~~~LGEMC~~~

POV Unknown

Little Hangleton, England

The sun had set a few hours ago. A tall, thin, snake-faced man, though "man" was a rather generous description, sat at head a long table. His followers sat at the table's sides, listening to their lord as he described a master plan of insane proportions.

"Halloween night, the night where the boundary between our world and the spirit world is thinnest. That night, we shall gather. That night, I shall summon forth Tartarus, the spirit of the abyss, and he and his monsters shall devour our enemies."


A/N: You're welcome for that long chapter. Ten pages, 4355 words.

I do my best writing while traveling, and as I type, I am 34001 feet above the Pacific Ocean on my way to visit my sister in Hawaii. I just love love love flying. My mum hates it, but it's the best part of the whole trip to me. And I get ten whole hours of air time each way. Shout out to anybody who's ever flown out of Dulles Int'l (IAD). And anybody who's ever flown in a Boeing 767, it's my first time in one and I love it.

Bottom line: Expect another update sometime in the next week.
