GEORGE'S POV
DADA classes were a nightmare for everyone since the beginning of the year.
Sitting for hours and learning basic books without doing magic? What were they? Muggles?
It's not like they didn't have bad teachers before, almost nobody could understand Quirell and Lockhart was the dumbest person who ever studied in Hogwarts, considering he never managed to cast even a first year's spell right, but at least they were interesting.
Umbridge? Boring as hell.
Of course, the DA secret club was only a tiny bit better, they could at least cast Hexes at people and practice, which was nice, but the level of the spells was so low and unimaginative!
They would have used the time to work in the ROR on pranks, but Harry seem to live there while also in class working on something, which he could do with their time turner.
They were well aware that Harry has a time turner, you can't not notice it when you have a version of the marauder's map, but they never pushed knowing he use that to have time for all his projects, the ones with them and the ones without while also have time to relax.
Yet, since the last Hogsmeade weekend, even his free time was dedicated to working on his project.
Which was why, when they noticed that Luna starts to disappear together with Harry, both Fred and him confronted them.
"What is it that you are working on, Harry?" Fred asked as they looked to the inside of the box Harry build where Luna set on a comfy chair humming in thought as Harry stood with a board and chalk, writing Archimestical equations that from all the products they made George could tell were a bit off.
"Finally decided to ask?" Harry smiled.
"Well, when we saw Luna was pulled into it, we had to know what's the big deal." George answered.
"Oh, nothing much." Luna answered to them still looking at the board. "Just disproving half the magical theories in the world." Before I could even demand explanation Harry spoke. "Not Half... but yeah. How about you come in?"
As we walked in George wined as he felt himself become heavier, and looking toward at Fred, he could see he want the only one.
Yet, a few moments later, his body became lighter than it was on the outside.
"What was that?" George asked.
"That was your magic being freed from outside influence." Harry said
"You could have warned us." Fred grumbled.
"I told him not too," Luna said. "He forgot to mention it to me, so I felt it would be fair for everyone to experience it like that, not to mention funny." She giggled at our faces and George couldn't help but have a smile grow on his face.
"Anyway..." Harry said and begin explaining about the spiritual world, the room and everything he has learned in it.
"Anyway, after I recreate the room I started working on basic arithmency, with Luna joining me soon after, but even after those two weeks, we only managed to determine that there isn't any number that is stronger than the other which means that a lot of the equations that are based on strong numbers aren't real and only work properly because of the spiritual world supplementing it."
Looking at his twin with both of them nodding to each other. Fred was the one who said "How can we help?"
"Really? It's not all fun and games." Harry said.
"Oh, that means that there will be fun and games." George said with a smirk.
"That was my idea actually." Luna smiled, it was what we were working on right now to complete." She pointed at the board. "It's time to take Duel monsters game to the next level."
"What next level?" The twins asked at the same time.
"It's time for the players to truly become part of the game."
TWO WEEKS LATER
(a day before Halloween.)
FRED'S POV
"Hello everyone!" His voice was loud enough for everyone to hear thanks to the spell he had on his throat. "Teachers, students, and a.d.u.l.ts who sneaked in. Today is a special day, as this is the first tournament of the last year the official tournaments will occur in school, with me and my brother finishing our studies by the end of the year... well, if we finish." The audience laughed. "Of course," George continued after Fred when the laughter subsided. "With this year being the third since the creation of the game, we decide to let this tournament be the beginning of the third, and for now, last way to play the game." The cheers were deafening.
"With the first way as regular card dueling, in which you summon creatures, warriors and wizards, cast charms and activate traps. Something I'm sure you all enjoyed to play." Fred spoke again. "And the second way as speed dueling on the specialized turbo brooms that make the game into one of skill of flight in addition to mind and magic, I'm sure you are thinking - what more can those handsome, funny, husband material," Fred winked at Angelica "Genius gods on earth think of?" Once more laughter filled the air. "Well, the new level is beyond all that!" George said. "It is time to truly get involved with the world of duel monsters with the new arena of ours." They both threw three cubes onto the ground, who assembled together and created a large size SWOR room with a few upgrades in it.
The last two weeks have been exhausting for the twins and Luna as they joined Harry in his time travels, but with them helping him with both suggestions about improvements, asking Dad to send the finished product of the TV, and actual help with illusion magic as they are masters with it. (Both Pranking and creating cards in the beginning needed it.) they managed to finish the new dueling arena.
"This arena was enchanted, just like the turbo brooms, to be able to make the monsters feel even realer, by making them capable of touching you." Fred's words caused the audience to be filled with shock. "You heard that right! Getting into the arena make you able to interact with your cards, but that's not all, while in there, you will need to use the field that's been given to you, and the monsters you summon, to find, while dueling, the fast magic cards that the arena has in them, which are cards that once found can be used at anytime, including your opponent's turn, right from your hands." The roars of excitement were deafening.
George waited for his turn to speak once everyone were quite. "But be warned! The speed magic cards can also malfunction and create an unknown affect." He smirked at that. "Now, as this is the first tournament with this new way, and as the students sighed up to either the regular of turbo dueling, this time, only the winners of each tournament will get to play in the interconnected finals. Well, let's begin!"
HARRY'S POV
Harry had a lot of fun the last few weeks with his friends helping him in developing the SWOR into an experiment room.
By the time he finished the second SWOR, Harry knew how to make one, even large one, in two days, so that wasn't the main problem.
The main problem was the additions.
First of all, they needed to connect the rooms to the Philosopher stone and the AIs, as they are what makes the game work and take magic from them.
Connecting them to the SWOR turned out not as hard as he thought, as magic itself had no problem working in the SWOR, magical effects.
Which is why, instead, Harry build a new AI into the room, making it a part of the room before animating it instead of making it into a golem as golems don't work in the room, then, with the SWOR capable of understanding the cards, and, with it being conscious, capable of also giving magic intent, a simple magical conversion device was created, which the AI can use to create solid illusions.
As light can be solidified, illusions can be as well, and while science isn't capable of doing so for the time being, magic is.
Fred and George added multiple settings to the fields in which people can begin their games in and how to make illusions more realistic, while Luna helped with the creation of solid illusions, as with her knowledge of creatures, it became possible to imitate magical animals capable of doing the same.
The fast spell cards were her's idea as well.
Those cards are filled with basic and later on, complicated magical equations that the AI is supposed to make actually work instead of just make an illusion of it.
They did make sure non of the cards can be used for dangerous affects as they are all charm based equations, and even then, lower level ones.
Other than that, they also put enchanted video cameras hidden in the room and had them connected to the TV outside by taking the TVs Arthur sent the twins, and recasted them with blacksmithing that the room's AI done as that makes the item be in harmony with the main spiritual realm of the room and not stop working.
All in all, they created a great arena and room to learn the true mysteries of the world, though it will be improved by the time this school year is done as Harry decided to divide his time once more between figuring out the math behind magic, and learn how to make his own ROR.
Not that any of that mattered right now, as he walked into Azkaban with his golem- Voldemort and Grayback, about to free the Death Eaters
