•••••
The sea and thunder will adventure across lands,
Pushing the hands of time,
The chosen shall seek to understand,
But the past will raise at the chime,
And if the half-bloods fail, the dark will charge as planned.
•••••
One moment Percy and Jason were talking to their girlfriends and then the next they're crashing through a roof in a completely different time. Faced with challenges, lies and three very suspicious students, the two demigods must find a way back to their time before it is too late.
But someone is working for the enemy, Hogwarts has a traitor in its midst.
And unfortunately, the enemy is one that Percy is all but too familiar with...

Before we begin:
•I do not own Percy Jackson or Harry Potter. All rights go to Rick Riordan and J.K Rowling
•This is set right after Blood of Olympus so Trails of Apollo hasn't happened and Leo hasn't returned with Calypso yet
•Jason is sixteen, Percy is seventeen and the trio are fifteen/sixteen
•This is set during the Order of the Phoenix
•I am trying to stick to the original dates so I checked online and it says that the Blood of Olympus was set in 2010 and it says the Order of the Phoenix was set in 1995 so those are the two years I'm using
•This is NOT a Jason and Percy romance
•NOT SPOILER FREE

Remember (A Percy Jackson Fanfic)
After losing the one closest to him, he disappears for quite a long time. Another war is coming. Against an enemy that was never seen before. A war that will decide the fate of the whole world. A war that would make the previous ones look like a birthday party. Who is the enemy? Who is the one that seeks to eradicate Olympus? More importantly, who will stop them? This is not like any of the other Guardian of the Hunt stories. I've tried to include some twists and different things in this to make it unique. This is NOT a Chaos story. This is not a story where Percy is an overpowered being that can squash Zeus in a second. He is just a normal demigod with the blessing of ONE Olympian. I don't own PJO/HoO. Rick Riordan does. I only own the storyline, plot and any original characters.Complete

When Wand and Sword Collide || Percy Jackson/ Harry Potter
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.]Complete
Fall Of The Eldest - Percy Jackson
{ after Blood of Olympus, Jason is still alive, Leo might be in this story, IDk how this will go, SOLANGEO OFFICIAL!!!} So this is my first PJO fanfiction, so please don't judge me to harshly. Hope you enjoy! I do not own the series Percy Jackson and the Olympians nor Blood of Olympus or any of the characters from those books. That all goes to Rick Riordan. The only thing I own is this story plot of this story and the new characters you will see. After the destruction of Gaea, everyone just wants a break. Percy and Annabeth are preparing to go to college in New Rome, Piper and Jason want to spend time together, as do Frank and Hazel. And Will wants Nico to start taking a little more responsibility for his health. Good times. But a new threat is on the rise, one that no one could foresee. Nothing involving monsters or ancient gods, no. Corruption. Somewhere in New Rome, a son of Ares discovers a loophole, a flaw if you may will in the Roman camp's governing and quickly makes his way to a high stand of power over the camp. He is in control of the camp, immediately abolishing Frank and Reyna as Praetor. His first decree?... wiping out the children of the eldest gods. The sons and daughters of Poseidon, Zeus and Hades are now wanted against the law with little to no odds of survival. Friends are made and broken. Loyalties shattered. Secrets spilled. lives ended. Will this injustice crumble, or will the extinction of the most powerful and beloved demigods become reality? [ I hope you guys enjoy this, I've been reading Percy Jackson Fanfics for 3 years, about time I made my own! I might mess up on character plots from the other books, if so I apologize. ]Complete
{Discontinued} Wizards? At Camp Half Blood?
(Spoilers ahead if you haven't read Trails of Apollo yet. Sorry if timelines are mixed up, I would love for them to make sense but I tried to make them be as realistic as I could. Harry is 12-14 when Percy is born, it's cannon. So unless you don't care that I made them same age I wouldn't read this.) Hey Demiwizards, I got the idea from reading a bunch of Wattpad stories on the demigods going to Hogwarts and thought it might be cool to have it the other way around. All rights go to our queen Rowling and uncle Rick. All I own is my own made up characters and my plot. After Deathly Hallows and the first Trials of Apollo. Harry, Ron, Hermione, Ginny, Luna, and Neville go to Camp Half-blood. Maybe Nuna, I don't know, I ship it. Sadly it didn't happen. Piper and Jason are actually at Camp Half-Blood in this fanfic and Leo come back early. Most everything else stays cannon. Oh yeah, and for som reason, I am going to try and add Pollux into this, you know, Dionysus's kid. I swear Dionysus is the second most loyal god, Hera being the first because being the goddess of marriage does that to you. That is all for now. Bye, bye Demiwizards!Complete
Changing The Future
The Potters have a set of twins, a boy, the son of James, and a daughter that's not James's but Poseidon's. Poseidon possessed James when they were conceived. the story takes place in the original harry potter time line. Harry Potter and Percy Jackson are the same person. After Voldemort attacks the Potters, their son Jamie is hailed as the boy who lived when actually it's Poseidon's daughter, Andromeda, who goes by Andi. The Potters neglected her for the next year when Poseidon steps in and takes her. he takes her to a Witch named Sally Jackson. Shortly after the goddess Artemis was made an Olympian, a prophecy was given that foretold of a Demigod daughter of Poseidon, and that they would be soulmates. Artemis still makes her vow to remain a virgin, but with the loop whole that she would be able to break the vow when she met her soulmate. Four thousand years later, Artemis had almost lost hope of ever meeting her. When the big three swore on the Styx to never have kids again, she loses all hope. That is until about 35 years later when Andromeda was born. The Lightning thief and Sea of monsters pretty much stay the same with some minor tweaks. it's when we get to the Titans curse that the big changes happen in the timeline. I don't know how to incorporate any of the Harry Potter books just yet, only because Andi never went to Hogwarts. All rights belong to Rick Riordan and J.K. Rowling. I do not own either series

What will happen to the demigods at Hogwarts? This is my first story, so sorry about any mistakes.

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