-LEO-

I was enjoying my very much deserved party. Heck, I'd died and come back. It was only fair that me and the rest of the Seven got some time to rest and relax.

I grabbed a cup of berry punch as Donn the Faun came stumbling up to me. He was obviously drunk. He tripped on his own foot and fell onto a chair. "Hiya Leo..." he slurred. "Congrats on killing Gaea..." Donn held up a hand for a high five.

And then my night was ruined.

I shoulda known. Someone had to ruin my night. I mean, I have tons of enemies. How many people have I bashed with my hammer? But of all people, I wasn't expecting her.

The world began to spin. And instantly, I was in a strange room. I think...

The walls were white. There was no door. I walked forward, stretching my fingers. But the wall never came. I was... floating in empty space?!

Poof.

Eight others materialized next to me. It was Thalia, Nico, and the rest of the Seven.

"What the heck?" Percy wondered aloud. "Where are we?"

Annabeth swept her stormy grey gaze over the 'room'. "Only one person could have done this: a god or goddess."

We all groaned, but then there was a brilliant flash of light. I opened my eyes to see someone very unexpected.

Hecate.

Everyone was shocked. Then Hazel dropped into a bow. "Lady Hecate," she murmured. The rest of us followed suit.

"Er, I don't mean to be rude, but why did you summon us?" Jason asked.

"Because I have a mission for you," Hecate answered. "A quest."

Everyone groaned. "But we just defeated Gaea. Can't we rest?" pointed out Piper.

Hecate stared at us. "I would like for you to help me. Please sit, this explanation may take a while." With a wave of her hands, a big sofa appeared. It was big enough for all of us, so I plopped into the soft chair.

Hecate summoned a chair for herself and continued her explanation. "A long time ago, I created wizards." Annabeth looked confused and opened her mouth to object, but Hecate silenced her with a look. "These wizards are real, they can do magic. They live all around the world, but mainly in England. There is a wizard who believes in blood purity and wants to kill all muggles, or non magicals. He also wants to kill muggleborns, the children of muggle with no magic blood that I blessed. He is trying to kill Harry Potter as there is a prophecy stating that Potter has the power to defeat him. He is Voldemort."

We all nodded, digesting the new info.

"Wait, do you want us to protect this Potter guy?"

"I will get to that. First, the explanation. Anyways, Harry Potter and his friends are going to skip their final year of school to hunt horcruxes. Voldemort-"

"A hor- what now?" I asked.

Hecate stared at me in exasperation. "Horcrux. Anyway, a horcrux is something that you put part of your soul in. You must destroy the horcruxes before you can kill the maker. Voldemort made several. My task for you is not to find them or help the trio find them, but to go to their school, Hogwarts. Keep an eye out and protect the students if the Death Eaters, Voldemort's followers, attack. In the final battle, fight and turn the tide. I fear the wizards may lose to the Death Eaters."

I suddenly realized something. "Wait... Is their school named Hogwash?"

"Hogwarts, Leo. Hogwarts," Thalia corrected.

"...I think that's even worse than Hogwash."

Hecate coughed to regain our attention. "Does everyone understand?"

Nico frowned. "Wait a second. We don't know these wizards, never even knew them until today. And you want us to help them? We just got out of a war!"

"I understand," Hecate sighed. "I do. But I fear Voldemort will reign. Please, as a favor. I did help you in the Giant War."

Nico gave up. "Fine. I'll go."

Everyone nodded assent.

"Terrific," Hecate announced. "I will inform Chiron of your quest." She waved her hand, and a table appeared. "These potions will give you all the wizarding knowledge you need. They will also age you so you are 17." Nine potions instantly appeared. "And these are your wands. Your name is on the box." A pile of boxes appeared. "Go on.

I lifted my potion, everyone doing the same. It looked a strange purple. I gulped it down and felt information flooding into my brain. I suddenly knew the exact definition of a Animagus, whatever that was (even if I knew what it was) and tons of other spells. Then I suddenly grew taller and less scrawny. So this was what it was like to be 17.

I grabbed a box with my name on it and tore it open, ignoring the scrap of paper that said something about the core and wood. I couldn't care less about what my wand was made of. I gave it a wave, and a tingling sensation flew down my arm. Sparks trailed behind it.

Hecate tapped her foot impatiently. When we were done examining our wands, she returned to her explanation. "Now, the quest. The potions you drank will give you the ability to do magic. You will still have your demigod powers, should you need them. Though, please don't reveal yourself as demigods. Only do that if the situation is dire." She paused to look at us. "Now, your bags are packed with everything you'll need. I will make your weapons like Riptide. They will become whatever object you want and will turn back to weapons when you need them. I believe that is all." She tossed us each our trunks. "I'll send you off. The potions will provide your backstory and anything you will need to know."

"Wait, now? But-" Piper cried.

There was a flash.

And we were off the save the witches and wizards of England.

A/N: Okay... Here it is. The Deathly Quest! Leo is back, ignoring ToA. Also pretending the timeline is lined up. This is set in the seventh year, taking place in The Deathly Hallows. I planned to upload more chapters before posting, but I've been busy. I had to do this big project. And I. PROCRASTINATE. A lot.

Not much is known about what happened at Hogwarts during the Horcrux hunt, but I will stick with what I know (Carrows, DA, fake Sword of Gryffindor).

For this story, I'll try to post every 1-2 weeks, or sometimes every 2-3 weeks. I'll post the second chapter on March 1. Hopefully.

Please check out the poll on my profile! I don't know which houses to put them in yet.

Please review! Tell me if you liked it, hated it, what to do next time. REVIEW!

Oh, and Happy Valentines Day!
