The war was over, Gaea was back in the dust, and Percy could finally get some well needed rest. He couldn't wait to spend the rest of his life in peace, living in the Roman town with Annabeth, occasionally visiting the rest of his friends. It was going to be a good life.

Or maybe not.

A new threat is brewing and it doesn't look like one that can be solved by just ignoring it.

When a bunch of wizards come to Percy's house to tell him that he had yet another evil grandfather, things turn upside down. He's dragged back into the hero life by his ankles.

Meanwhile Harry is also having a hard time. There's been many things on his mind this past year.
-A Defense Against the Dark Arts teacher with a personality like poisoned honey
-A venomous, disgruntled house-elf
-Ron as keeper of the Gryffindor Quidditch Team
-Malfoy's annoying antics
-The looming terror of the OWLs

...and of course, the growing threat of He-Who-Shall-Not-Be-Named and his newest addition to the family. A grandson named Percy.

This story takes place after Blood of Olympus and during Order of the Phoenix. How will things end for The Boy Who Lived and The Savior of Olympus?

[1] New Beginnings: Percy Jackson, Harry Potter, and the Philosopher's Stone by ssamkayy

[1] New Beginnings: WARNING!! Story is technically complete but I started editing literally years ago then never finished so the beginning's a little funky! Percy Jackson was adopted at the age of seven by the nastiest family in the world: the Dursleys. He met Harry Potter, the most wonderful person in the entire universe, that same day. Though completely unrelated, the boys were nearly identical, a connection forming between them that would last years to come. The pair would go through life as brothers in everything but blood. Connected at the hip, these seemingly average boys had much more in store for them than they could ever imagine. A note: Percy Jackson doesn't discover anything about the demigod side of his universe until later in the second book. Just a warning. If that's too slow for you, don't read. DISCLAIMER Note that I do not own anything that was created by J. K. Rowling or Rick Riordan. I only own some of the plot and the occasional person or place that I may create myself. WARNING When people comment mistakes, I come back and I make sure that they're fixed. So, I'm still editing.

Swords and Wands (a Percy Jackson and Harry Potter crossover) by Kara_Sage

The war was over. At long last, Voldemort was dead, and this time, he won't return. Unfortunately, those who were attending Hogwarts during the war were unable to learn anything. So of course, when Hogwarts sent all those students letters offering to have the re-do their previous year, everyone jumps at the chance, all of them thinking that they would finally have a peaceful, or at least uneventful, year at Hogwarts. It wasn't one. Perhaps Draco Malfoy was partially responsible for that. Perhaps the year was doomed to be chaotic from the day it began. Or perhaps the Fates had a grudge against everyone who chooses the path of a hero. DISCLAIMER: I DON'T OWN PERCY JACKSON OR HARRY POTTER!! ALL RIGHTS FOR CHARACTERS FROM THE BOOKS GO TO RICK RIORDAN AND J.K. ROWLING! ANYTHING THAT BELONGS TO ME I WILL CLAIM IN THE PROLOGUE!

The Other Castellan by astromythical_

Draco Malfoy was hiding. Not from the Gryffindors, not even Voldemort himself. No. He was hiding the truth from everyone. Born in America, being a Half-Blood, growing up with his insane mother, the younger brother to Luke Castellan, the best swordsman in the last 300 years, the first demi-wizard in his year to attend Hogwarts, Lucas Castellan had a lot on his plate. But he couldn't tell anyone, or else both worlds would be destroyed, and that would be his fault. And he wouldn't want that, would he? Join Lucas(or Draco, if you prefer), as he undergoes his perilous and very much annoying quest to protect "The Boy Who Lived," otherwise known as Harry Potter. ~~~~~~ The current word count is 100 521 as of Chapter 36. ~~~~~~ Rights to J.K.

Saving Wisdom and Wizards || PJO x HP by alternativekitkat

Being a half-blood isn't easy, and it doesn't get easier. Of course, fighting in two wars and being drafted into a third doesn't help. But there are those lucky ones. The ones who survive and move on, have families, education, life. Percy Jackson is not one of them. He's a demigod and apparently, a very powerful and hated wizard. Percy is tasked with helping the Wizard World, and protecting Harry Potter, which is hard to do when Harry wants nothing more than to kill him. ~~~ *Completed* Sequel is up! Check out Hidden Wisdom and Wizards :) ~~~ Rewrite is also up! Same title, but with gray cover. I highly recommend checking that out as well! ~~~ Highest Rankings: #1 Percy Jackson #1 Percabeth #1 Annabeth Chase #1 Wizards #1 Dark!Percy #1 Heroes of Olympus #1 Rick Riordan #1 PJOHOO #2 Crossover

Another Evil Grandfather 《COMPLETED》 by League_to_Legend

Percy had his day planned: eat, spend time with Annabeth and stay out of trouble. I can assure you that nowhere in that plan included getting a visit from Gandalf and a miniature version of himself to inform him that he has another evil grandfather. Great! (note the sarcasm) Taken to Hogwarts for his 'safety', Percy's year looks set to be eventful, again. Not to mention that Moldeshorts knows of his existence, or more importantly his demigod heritage, and wants to recruit him. But first Percy has to get through the year. Can Percy make it through the year without revealing the Gods and demigods' existence? *set in the Order of the Phoenix and after The Last Olympian* *The Lost Hero hasn't happened yet* *Percy is 16* *Harry is 15*

Percy Jackson: Twins by AhsokaTanoJedi

It's been a year since the Second War, yanknow, the awakening of none other than the lady herself, Queen Dirt-Face. Percy has been living a happy life, until another great Prophecy is told. Percy gets thrust into another war, but this is no ordinary war, it's a war of revenge against him and this boy in London. Percy is forced to flee, for if he stays any longer at Camp, every camper will Perish. It's been about two years since they won their war, and defeated He-Who-Must-Not-Be-Named. Harry Potter is the current headmaster at Hogwarts, much to his displeasure. He married Ginny last year and is currently very happy, that is until The Ministry of Magic decide to show up and drop a bomb on Harry. (Not literally) Ron and Hermione try to help Harry cope with the information he is told, however they can only do so much to help their friend. What will happen, when two brothers, separated at age one, do when they find out about each other? What will happen, when wizards meet Demi-Gods? What will happen, if Percy's and Harry's enemies team up, to get revenge on them who defeated them? Read to find out. Disclaimer, I only own the plot line and story. Everything else goes to Rick Riordan and J.K Roweling.

[2] Diverging Paths: Percy Jackson, Harry Potter, and the Chamber of Secrets by ssamkayy

[2] Diverging Paths: Perseus Jackson, also known as Percy, left his first year at Hogwarts School of Witchcraft and Wizardry feeling happy and confident that he had actual friends. However, that was before they seemed to forget all about him. He at least had his brother, Harry Potter, but he too had gotten no letters from their friends. Then one day a small creature wearing a pillowcase showed up in their shared bedroom and told them that they absolutely, positively could not go back to school under any circumstance. Of course, the small creature wearing a pillowcase was resolutely ignored and they went back to school to start their second year anyway. Then things started to go wonky, what with all the strange voices and massive spiders. But then things got even stranger. Water seemed to bend to Percy's will and he kept feeling as if the forest was watching him. DISCLAIMER Note that I do not own anything that was created by J. K. Rowling or Rick Riordan.

When Wand and Sword Collide || Percy Jackson/ Harry Potter by galaxiasgreen

Percy Jackson wakes at Hogwarts. Harry Potter wakes at Camp Half-Blood. Neither know who they are, where they are, or where they come from - but when the line between demigod and wizard blurs and a sinister prophecy arises, Harry and Percy must unite with Hermione, Ron, and Annabeth before it's too late. [WINTER 2023 UNDERGOING REVISIONS] --- Harry and Percy swap roles story, with an original plot and prophecy! Altered Timeline, taking place in 'modern day', after the war with Gaia assuming everyone survived (as this was written pre-HoH and BoO) with no canon from MCGA or ToA, and around the start of Harry's sixth year, where no events of HBP have occured (i.e. Snape is still Potions Master and Draco has not been chosen to kill Dumbledore). Percy and Harry are around the same age. Chapters alternate between 1POV for Percy and 3POV for Harry. [Luth art by Rowen Satell.]

Guardian of the Golden trio (Under some serious editing) by crazy_mjb

Percy Jackson to the rescue again, but this time, it's not as easy. Not only has his old evil grandfather Kronos Aka the time freak risen again, but he brings along another friend. An all evil all powerful Wizard that goes by the name Voldemort. Percy gets dragged into yet another war of tyrants, and the protection of the boy who lived. But will Percy be able to overcome the sadness and grief of his friends deaths, and win this deadly war? Or will he crumble and fall to the pressure of saving lives? Ok, this story has been edited, or is in the process. There is a second book to this, but i'd advise you not read it yet otherwise you will be thoroughly confused. AND finally, I had a very.... nice chat with Thanatos and got back the following characters. No death threats against death involved... Fred Dumbledore All the dead members from the order of the phoenix and that's it I think. I don't know when the story is set in Harry Potter times, i've just mixed and mashed
