Summary

More importantly for my writing-
I starting writing in 2021 in Highschool. This work is a testament to how far my writing has come. I believe after taking multiple, LONG breaks, chapter 17-19 is where I really pick up. Cross posting from FF.
I will soon be deployed, I intend to finish this work in 11 months from this date. 20250726. I will post en masse everything I have, editing early chapters containing mediocre writing at best. Please leave your concerns and comments. Your praises and insults, so I may grow, and you can see what you want out of this story. -

Summary
After finally finding his godfather, Sirius Black, Harry hopes for a new beginning—only to be told by Dumbledore that he can't stay with him. Thankfully, the Weasleys whisk him away from the Dursleys for some much-needed fun at the Quidditch World Cup. But, as always, trouble isn’t far behind.
With a new school year at Hogwarts comes even bigger surprises. The legendary Triwizard Tournament is set to take place, bringing excitement—and danger—to the castle. But that’s not the only change. This year, Hogwarts has hired not one, but two new Defense Against the Dark Arts professors: the grizzled and unpredictable Professor Moody, and the effortlessly charismatic Professor Jackson. While Moody seems outright mad, Jackson is almost too perfect—so perfect that the Golden Trio can’t help but wonder… why is he getting so close to Professor Snape?

Summary
~o~
You’ve all heard of the boy who lived, Harry Potter I’m sure. And the Son of the sea, Perseus Jackson? Two great heroes of two different dimensions. But what if they met? No, not in fifth year or whatever the other universes do, but from the very beginning from their first year? What if the golden trio never came to light, but a new, better, Obsidian duo did? Join the two heroes in their epic journey against the world.
Or,
Percy finds out he’s a wizard (read the tags), Harry gets the love he deserves, Mrs. Jackson is an entity to fear, Tom Riddle regrets life, Dumbledore is a manipulative piece of shit, Revolution of the demigods and the obsidian duo are hard-core Slytherins.
~o~
The only thing I own is the plot and idea.

(edit) This is the first book of the trilogy series

(Edit: This fic is abandoned and up for adoption. See last chapter for details.)

Summary
Percy was not living his best life at the moment. At least that’s what he’d assume seeing as he doesn’t know what his old life was like. Unable to remember anything since before he woke up at the Wolf House, Percy makes his way West trying to find the camp Lupa told him about and maybe the mysterious Annabeth he sometimes catches glimpses of in dreams. Unfortunately, he runs into a bit of a snag on the way there. This might be a lot harder to do than he first thought.
Harry was dreading whatever new thing would try to kill him this year. If the last three years at Hogwarts told him anything it was that people really wanted him dead and that the murder attempts were tragically going to be a trend. With the news of the Triwizard Tournament he figures maybe his crazy life will take a backseat for a while and maybe he can actually relax for once in his life. But no, it’s never that easy is it?

Summary
“Right, well, Percy’s dead.”
It was a dumb thing to say if you wanted to avoid uproar. Hazel who had been fed ambrosia and had recovered quite quickly, was leaning against Frank, and her had snapped up at Thalia’s words. Chiron and some of the seven had managed to calm down the rest of the head counselors although they themselves looked as if they wanted answers and wanted them immediately. Finally Piper yelled for everyone to ’shut up’ using her charmspeak and things quieted down quickly.“It’s-It’s not possible. I-I would’ve, I would’ve felt him pass.” Hazel stuttered as she propped herself up on Frank. She then looked to Thalia, accusation written all over her face. “You never told me that! I thought, I thought you were asking me to use the mist for a different reason concerning Annabeth’s lack of presence.”
