Magnus Chase At Harry Potter

Seventh Year(HarryPOV.)

I could not believe it.
Six years of my life preparing to defeat a big, bad villain. Now, I've done it!
What's even better is the owl.
It had a letter attached to it saying;
"Dear Harry James Potter! As the school as been rebuilt, we are offering a chance to everyone to re-enroll into The Hogwarts School Of Witchcraft And Wizardry. Your booklist has been given below. We await your presence."
After a few minutes of scribbling, I held the letter meant for my best friend, Hermione Granger.
I dashed to the cage were my owl, Hedwig, was and opened it.
I stopped as I looked inside the cage.
All it had was a feather.
A feather that had fallen out of her after she'd been...
I felt warm tears roll down. It had already been a year.
A year since all of those people...
Fred, Lupin, Tonks, Hedwig, Colin, Sirius...
I wiped my eyes and went downstairs.
After the war, I had moved in with the Weasleys.
It was nice, I could see Ron any time and Ginny too.
I walked into the kitchen and sat on a stool, Ron dragged his feet down the stairs and sat beside me.
I looked at him and shoved the admission letter into his face.
His red hair was messy and his long nose had freckles across it. His dark eyes glanced down at the Hogwarts stamp and he glowed.

A few weeks passed by as quick as dogs.
We stood a few feet away from the pillar with the sign: "9 3/4."
I smiled at Ron, he smiled back. Lugging my luggage behind me, we ran.

(Percy POV.)

I was surprised that the brick wall was, in fact, a doorway.
I glanced around, the rest of my friends stood around me in a surprised state.
Leo touched the wall we had gone through and muttered,
"No mechanics, pure magic!"
Nico mumbled something about being impatient and we made our way into a giant, maroon train.
We got inside and found a compartment. A trio of people, two boys and a girl, sat there, one of them had hair as black as mine, another was a ginger while the girl had dark-brown hair. They glanced at us and the girl said in a British accent,
"New? You can squeeze in if you'd like to, no more compartments left, after all,"
The girl got up and sat beside her friends who were across her, she gestured at the empty seats with a smile.
One of the boys, the one with jet-black hair, stared at my bicep. I was wearing a shirt with short sleeves that made my tattoo barely visible. I smiled at him and pulled down my sleeve. He narrowed his eyes at me with suspicion.
We tried to squeeze in.
Nico and Hazel sat beside the three.
The rest of us sat, squashed, in the seats across.
"So, what're your names?" The ginger asked.
We introduced eachother and they did the same.
The suspicious one was Harry Potter.
The ginger was Ronald (He prefers Ron.) Weasley.
The curly-haired one with brown hair was Hermione Granger.
We spoke to each other, not the three, in Ancient Greek. That confused them.
(Slanted writing is Greek.)
"So, any ideas as to what we do now?" Leo asked.
"Er, what mate?" Harry asked us.
"Oh, uh, we're foreign. From Greece." Annabeth answered, quickly.
Hermione perked up.
"Greece? Are you foreign exchange students?"
We nodded nervously.
A few more awkward minutes passed by.
Nico sat beside the window, trying to avoid our conversation. Hazel had fallen asleep and leaned her head against the compartment door. Her head slipped and she rested it against Hermione's.
Hermione smiled awkwardly at us and avoided eye-contact.
Nico glanced over and said,
"We can switch."
Hermione seemed relieved and held Hazel's head up as she stood and swapped their seats.
Nico patted Hazel's head and leaned his against hers as he fell asleep too.
"Are they...?" Ron pointed.
"Siblings," Frank replied.
The train began to slow and Harry stood up,
"We should put on our uniforms now. Since you're not sorted yet, you won't need any ties."
The girls left the room, Hazel had to be shook awake.
As we changed, Ron commented on our scars.
We nodded nervously, struggling to make up stories.
"Woah, is that a tattoo?"
Harry snapped his head towards our direction and stared at my branding.
It was a trident with several stripes to signify my father and how long I'd been at Camp Jupiter.
"Yeah, uh, a tradition in our family," I pulled on my sweater and black robes quickly.
I noticed Harry kept staring at me and I glared back.
He turned away.
(Harry POV.)

I wasn't sure if that tattoo was another form of the Dark Mark. I had to tell Professor Dumbledore.
I hoped that we didn't have any adventure this year, I was tired.

A/N:
