First: Don't talk too much

When it started it had been a boring, some might even call it a normal day. Percy and Annabeth woke early in the morning, despite it being weekend. They wanted to pack their things because the next week they were moving to New Rome. Sally, Paul and Estelle were on a trip to the store, so they were alone. Still, they never got as far as packing their things. Before they were able to, they heard a cracking noise from the living room. They looked at each other and walked slowly and silent slightly crouched from the kitchen to the living room. Where talking voices were stationed.
"This is not how I imagined the last descendants of the Gaunt family would live." The man didn't explain it further what he meant. Instead, another spoke, "My lord, shall we search for them?"
A nasal answered, "No Lucius, Nagini tells me, there are two persons on the other side of the door", the man made a short pause then spoke louder, "come out from where you are hiding or you will be brought to me."
Percy and Annabeth looked at each other contemplating what to do. After a short conversation consisting only of gestures and mimics, Percy just shrugged his shoulder and stood up, showing Annabeth his intentions, who just rolled her eyes and followed him through the living room door. Only for Percy to stop so suddenly that Annabeth nearly ran into him. Not the slightest bit surprised that Percy had stopped when she saw the figure in the middle. An appalling man with skin so pale it was something between white and translucent, eyes red like those of albino mice and instead of a nose he had two slits, not unlike the vertical pupils of some snakes.
Percy asked with narrowed eyes and a growl, that he had most likely learned from Lupa, "Who are you and what are you doing in my mum's living room?"
"My name is Lord Voldemort. I am here because relatives of mine are living here. And you are?"
"Percy Jackson. And I certainly doubt you are a relative of Paul, he never mentioned having any ties to nobility, and Mom's family is dead, so please leave now after you answer me this question: why don't you have a nose?" Percy's ADHD just couldn't stray from the fact, that this man in front of him didn't have a nose, so he looked like a mix between a zombie and those skeletons Nico was so fond of summoning every once in a while.
Though Percy's speech the man's slight smile was getting smaller and smaller until he looked with narrowed eyes at him.
"That is of no matter here. As it is, if you are indeed Perseus Jackson, then you are the one I was looking for. And since you didn't know who I am, I am also assuming you aren't going to Ilvermorny", he wanted to speak on, but Percy interrupted him. "What's an Ilvermorny? Something for ill people in Vermont?"
Lord Voldemort straightened to his full height, one could notice his restraint, as he spoke, "Ilvermorny, is a school founded by the descendants of Salazar Slytherin as you are one, even though Gormlaith's niece was a traitor. What I hope you won't be."
Percy interrupted him, all the while forming a T with his hands.
"Time Out, One of my ancestors was a slithering salsa dancer?", Percy exclaimed and added thoughtfully, "Or was it salad czar?"
"It is SALAZAR SLYTHERIN the greatest of the four founders of Hogwarts." Voldemort thundered his patience wearing thin, "But that is of no matter. What is important, is that you will come with me and my loyal Death Eaters" before Voldemort could add *and become one of them*, Percy interrupted him again.
„Death Eaters? Seriously?", Percy asked exasperated, "Don't you have more imagination? What about? Harvesters of Souls, Harbinger of Death? Even Killing Group would be better. Because Death Eaters? That's just gross. What do you do? Eat rotting flesh? Or do you try to catch the Grim Reaper for dinner? But that much flesh can't be on the Grim Reaper, except if you mean Thanatos. By the way, did you know Thanatos looks like a cupid? He did at least when I met him once. So actually eating *him*... could get a completely different meaning that's even more gross. Or is it grosser?"
To answer his last question Annabeth pinched in Percy's rant, "both work, Seaweed Brain, but didn't you want to ask these lovely people what the Hades they are doing in our apartment?"
Percy looked like a scolded puppy at Annabeth, "yeah, right, sorry, ADHD.", he turned to the group with a nearly blank face, "So what the Hades are you doing in our apartment? And please, quite brandishing your sticks you could gouge somebody's eyes out."
Now Lord Voldemort resembled Alecto on one of her worse days, in other words, he was the epitome of fury, "Those are no mere sticks as you call them. They are wands and they can do a quiet lot more damage than to gouge an eye out, although with the right spell it can also do that, but enough of that. There's much to discuss. Among that, how to be respectful."
Percy hid his snickering behind a cough, where Annabeth looked everywhere but Percy lest she also started to smile.
Lord Voldemort noticed it, so he used the "Silencio"-spell on both of them as well as a binding-spell. After that, he explained the situation while he was pacing through the length of the room followed by the movement of Nagini's head and his billowing cloak, that seemingly didn't bother him the slightest bit.
Pacing he told Percy, how he found out by chance he had any relatives left (or more correctly he used a spell to find blood relatives). After a bit of research of what the spell had shown him, he found out, Percy's decreased grandmother Estelle Jackson was his cousin because his uncle Morfin somehow sired a daughter between his jail times in Azkaban. Said daughter though was a squib and didn't want to be a disappointment to her witch mother, so she immigrated to the states.
Percy interjected him after a time, when the spell was worn down, with a question that tortured him nearly from the start: "So my great grandfather has a name that sounds like a drug."
Annabeth just signed exasperatedly before she explained: "Percy, Morphine is first and foremost an opiate that's mainly used as a painkiller. It's just a drug in too high doses. And you are one to talk, your name literally means 'to destroy' or loosely translated 'Destroyer'."
She gave him a pointed look.
Percy defensively responded: "Hey, that's not my faul-" But Annabeth interrupted him, "Maybe not intentionally, but you are the one that lives up to that name. Remember St. Louise, or better yet: Mount St. Helens. You blew that up. Literally."
"That was self-defence. I was attacked and I didn't think that the whole thing would explode, because of a bit of water."
Annabeth just shook her head in exasperation.
All the while Lord Voldemort listened intently but didn't understand a thing, so he didn't really comment on it, and continued in his tale.
He told Percy, that he quite recently regained his body and found out he had a relative, who showed after some research potential. To which Lord Voldemort said, "And as I'm now standing before you, I can feel it thrumming in you and know your potential is much greater than I anticipated. I can't understand why you aren't going to one of the schools. But nevertheless, have you understood what I told you?"
Percy, disliking the test like question answered with, "So my mum is your cousin's daughter and your cousin took first her mother's name and then her husband's because she didn't like the associations to her father's name, who was your uncle and who nearly killed your mother. Did I get everything correct?"
"Yes", answered Lord Voldemort bored and annoyed.
But Percy wasn't finished, "And why the Hell do you think I would help you? Because of a connection to my... What was it again?"
"Your Great Grandfather", Annabeth helped Percy.
"Yeah him, who was also your uncle, who tried to kill his sister. That's just messed up."
Annabeth just sighed, "Percy, some of your cousins and also some of your half siblings tried to kill you."
Percy sent her an irritated look, "Yeah, but that's different."
"How?"
"It was to be expected. With my dad being who he is."
Annabeth shrugged her shoulders, "Yeah, you're right."
Then Lord Voldemort cleared his throat, "I would appreciate if you would concentrate on the matter at hand. Do you want to join me, Perseus? As it is, my dear boy, you are the last descendant of the House of Gaunt of Europe apart from me."
This time it was Percy, who shrugged his shoulders, "No, not really interested. And, dude, that's way too many 'of's for one sentence. Other than that I would suggest you go into mental therapy. To get your head straight and get your unresolved problems with that interferior complex under control."
Annabeth quipped, "Percy, it's inferior complex, not what you just said."
"Just what would I do without you, wise girl?"
"ENOUGH", Voldemort's shout rang through the room.
Then they all heard a cracking noise and all hell broke loose.

To be or not to be continued?

AN: So, I don't know what you think of this story, it's not as good as I wanted it to be, so I'll probably edit it somewhere down the line. I for myself thought I would never write a Harry Potter and Percy Jackson crossover, mainly because there's already an abundance of those. But when I got the idea for this story and it didn't relinquish its hold on me, I decided to write it down and share it with you guys. Still, I was so fed up with some rather boring and predictable crossovers that I haven't decided if I want to make more of it than this one-shot, yet, lest my story gets boring or predictable.

This is an edited version of the chapter, but I also can announce that I'll probably continue this story, but I don't know, when the second part will be finished.

I own neither the rights to PJO nor HP as well as the pictures in the cover.
