I am posting each chapter of my Harry Potter/TOH fanfic
“Alright students! Gather around! We are going to the human realm for the triwizard tournament, just like we talked about. Don’t make me regret this. Please.” Bump called out to the Hexside students that were joining him on a trip to a human wizarding school. He had learned that a school called Hogwarts School of Witchcraft and Wizardry was hosting a tournament between it and its rival schools Beauxbatons and Durmstrang. Luz wondered how he convinced the human witches to let them in the triwizard tournament. Or maybe he hadn’t, this was all pretty out of nowhere.
"Now, when we get there, you're all going to write your names on slips of paper and put them in the Goblet of Fire. Understand?" Bump told us, then he opened the portal before anyone could ask anything.
They all had met in front of Hexside three days prior to have Bump tell everyone that we were doing this. He didn't explain what it entailed, or how long it was going to take. Typical Bump Luz thought.
“I thought you said that there wasn’t magic in the human realm. So how are there multiple magic schools on Earth?” Amity asked her girlfriend.
“I didn’t know that there was magic on Earth, I suppose they keep it a secret from normal humans.” Luz replied as a few students began to go through the portal door. “I wonder how we plan to get from here to Scotland, I don’t really want to fly over the entire Atlantic Ocean.” she pondered.
“Well, you’re in luck!” Bump told Luz, “We aren’t flying all the way to Hogwarts. We would be late if we did that, the portal door actually can link to other places than just your hometown. It is currently linked about 3 miles from Hogwarts’ location. We might want to be practical, but we’re still going to make a grand entrance!”
Okay Luz thought, turns out Eda hasn’t told me everything about the door. Maybe she didn’t even know it could do this. She smiled at Amity as the cotton-candy haired goddess walked through the door. Luz gave Bonesborough a wave goodbye as she stepped through into the human realm.
Luz saw that they were in a very hilly area, This definitely isn’t Gravesfield, she thought to herself. Luz shivered, having forgotten to dress for the weather. The last few students poured through the portal, then the door closed. There were 20 of them, Gus, Amity, Willow, Hunter, Edric, Emira, Skara, Boscha, Viney, Jerbo, Barcus, Vee, Mattholomule, Amelia, Cat, Eileen, Bo, Selene, Bump and Luz. Along with King and Eda, who weren’t supposed to be there, but joined anyway. Bump couldn't exactly stop Eda, as she held the key to the portal door.
“Everyone, get on your palisman!” Bump yelled at them, “Porter, Blight, Blight, Tholomule, cast an illusion to make us seem like the Titan’s skull!” Gus, Ed, Em, and Matt did as they were told, enshrouding everyone in an illusion. Luz was between Amity and Hunter, who had just carved his new palisman; a blue jay named Waffle that looked remarkably like Flapjack. Luz got herself steady on Stringbean, and they took off on the count of three, beginning their approach to the castle.
Professor McGonagall told Hogwarts that a fourth school had decided to join, Harry couldn’t quite remember the name, Hexagon? Hexway? Something like that.
They were told that the new school was going to arrive from the west any moment now, Ron, Hermione and Harry were all standing next to each other facing the forest. The courtyard was chilly, as to be expected in October.
“Any idea where this new school is?” Ron asked.
“Perhaps it’s Ilvermorny, the American school, but they are going by a code name for some reason. I’ve never heard of a school called Hexside school of Magic and Demonics” Hermione admitted, Harry figured it wasn’t Ilvermorny, he remembered hearing Dumbledore telling McGonagall that Ilvermorny didn’t want to join for the Triwizard Tournament, or, quad-wizard tournament now, Harry thought. Wait, isn’t there one in South America? No, that one’s called Castelobruxo.
After almost ten minutes of anxious waiting from the school, a giant horned skull appeared over the horizon, approaching the castle.
“It’s them!” Professor Flitwick shouted in excitement. The skull kept approaching, not seeming to show signs of stopping, it was going about 80 kilometers per hour, as far as Harry could tell. As it drew nearer still, a few of the first and second-years fled to the nearby doorway. Harry stood unflinchingly with the other older students.
Mere meters from collision with the castle, the skull evaporated as about twenty or so… people - or so Harry thought, some of them looked very non-human - on strange-looking brooms appeared out of thin air, all veering up in perfectly straight lines as they avoided the castle walls. Harry couldn’t help but be impressed by their coordination. I hope they play Quidditch, he thought, hoping for a good match.
The new arrivals landed, and some of their brooms disappeared in moments, and the headpieces on them, which looked like animals, turned into animals. That is wonderful magic! Harry thought, as a man with one eye and long black hair approached Dumbledore, Harry assumed that man was their headmaster.
“Welcome, Hexside school, to Hogwarts School of Witchcraft and Wizardry!” Dumbledore announced gleefully to them, “Please, Principal Bump, follow me!” The two headmasters departed for Dumbledore’s office. The Hexside students broke ranks.
The Hexside students started to mingle with the Hogwarts students, but none of them recognized Harry, much to his relief. Though Harry did seem to catch the attention of two students, girls about his age. One had pink hair, skin as white as paper, and golden eyes; the other had dark hair, brown skin, and a scar on her eyebrow. The Latina seemed to be staring right at Harry's scar. Harry tried to casually hide it, then failed at being casual, and at hiding it. Hermione told him off and said that he should try to make a good first impression.
