Disclaimer: I don't own Harry Potter or Percy Jackson and the Olympians. If I did, I would not be posting fanfiction.

Author's Note: If you don't like Harry as a demigod, don't read this particular story. I want to say the storyline takes place just a bit after Battle of the Labyrinth but it is not completely canon. Everything else should be explained in the rest of the chapter. So enjoy.

Hades' POV

Hades gazed at his son intently before continuing, " You are to take your place at Camp Half-Blood, and help stop Kronos. As you know doubt know, since you turned sixteen a week ago all the gods and goddesses will be looking to see what side your on. I am sorry to put this on you after the Second Wizarding War, but my hands are tied."

Hades looked on to his son sorrowfully, to send him end to the war was heartbreaking. Hadrian had only found out about his godly heritage six months ago, and now this is what he got in return.

Harry's POV

" You are to take your place at Camp Half-Blood, and help stop Kronos. As you know doubt know, since you turned sixteen a week ago all the gods and goddesses will be looking to see what side your on. I am sorry to put this on you after the Second Wizarding War, but my hands are tied."

Harry signed as he heard his father's words, he should of knew that with his sixteenth birthday would come the end of staying out of the limelight. Only reason he found out he was demigod was due to him brewing a heritage potion. All he wanted then was to know if he had any family left other than the Dursleys. Then all a sudden Hades, god of the Underworld, was shown as his father. He was magically adopted by James Potter so therefore looked like a Potter, but otherwise he had no claim to the Potter Family.

As he took in the information presented at the time, he went out to find his dad. Just to end in Los Angelus, California. Amazing what a tracking charm can do. Harry thought he surprised Hades when he came waving in and out of the Underworld like a pro. When he came up to the Throne Room, where Hades was residing, and knocked, Harry found out Hades had no clue he was born.

Therefore it was up to Hades to explain what was going on in the states. Which led to Harry to telling Hades how he had ended a war of his own by slaying a madman, named Voldemort.

So when Hades gave him the quest all he could think of was how Death loved a way being a half-blood made sense, it explained all the reasons why his life was a chance he responded to his father, "I accept this quest."

Hades just nodded his head, and replied, "Be safe, son. I am counting on you."

At that Harry knew he was dismissed. Turning to leave, he heard something come at him. As he had reflexes from being a war veteran, he caught the thing easily. Checking to see what was in his hand, he noticed it was a stygian iron ring with an onyx imbedded in up at Hades confused, he asked, "What is this for?"

Hades softened his expression, and explained,"It is a ring that turns into a sword made of Stygian Iron when you say 'Hades', it will automatically balance itself to you. Much like Nico's sword, it will help you control the dead and has the power to suck away its victim's essence. It is a gift to show you are my son. But be careful as it is able to harm those both mortal and immortal"

"I will do my best. It is an honor to receive such a weapon", Harry stated sincerely, then he whispered, "Hades". The sword that appeared in his hand was a stygian iron blade with onyx gems imbedded in the silver was magnificent, but it was not needed now. murmuring 'Hades' again, he puts the ring on his ring finger. Nodding to Hades and Persephone, he walked out of the huge room to head back to the ferry.

He could not help but feel relieved that his father trusted him with such a blade. Not many could say they had been blessed with such. As he walked to the front of the palace he worried about the outcome of his decision. He hated when the fate of the world depended on him, first Voldemort, now Kronos.

What is it about prophecies that always seem to include him? At least he was not the only child of the Big Three to be turning sixteen. Perseus "Percy" Jackson's birthday is on August eighteenth, and would be the only known child of such to reach sixteen.

As he mused, he bumped into something solid. Finally paying attention to his surroundings, Harry went to help up the person he knocked over. "Um, sorry for knocking you over." He said giving the kid a hesitant smile.

Nico's POV

Nico gazed over at the dark-haired boy in front of him holding a hand out. He took the hand and got pulled to his feet.

"May I ask who you are, and why you are in my fathers castle", Nico asked politely as he gave the strange boy a look over. The boy had messy black hair, pale skin, and emerald eyes that seemed to look straight through you. Nico held back a shiver.

The boy answered," Uh, I'm Hadrian Potter, but you can call me Harry. And Father requested me. You must be Nico, my half-brother."

Nico could not believe his ears, he had a half-brother? 'I wonder how old is he', he mused. Stopping himself from spacing out, he replied, "Yes, I'm Nico Di Angelo. Father?" He could not help but ask, he was under the impression that Hades was the only one who had not broke the treaty. Only reason he was here was due to getting placed in the Lotus Hotel. So that mean none of the Big Three were innocent.

Harry heard the question in his little brothers reply, so explained, "I found out Hades was my father six month ago. He told me today I was to be sent to Camp Half-Blood, with you of coarse. Being sixteen I need to be trained as a hero."

Nico's jaw nearly dropped when Harry confirmed what he feared. Another to fit in the prophecy. Thalia joined Artemis's Hunt to get out of the prophecy, and Percy is turning sixteen in two weeks. And now Harry was a candidate and if he had been talking to Father then he knew that as well.

"Well if I am to take you to Camp Half-Blood, we need to get going." Nico told Harry, turning to head to the exit. The ferryman was already waiting to give them a lift. Unlike Nico who was slightly wary of the dead, Harry seemed content around them. 'It's as if he's at home here, weird', Nico thought to himself.
