Chapter 139 - 139- preparing his friends

HARRY'S POV

Harry was extremely satisfied with the performance of the illusions.

Having a proof that his own runes work meant the next is to make more people use them even if they don't know they did, as while he works on strengthening his beliefs and make more runes work, the magic needed to power more of them them was beyond him for now.

As he continued to eat his second dinner for the day (the first was right about now before in the ROR) he saw the twins raise.

"Hello everyone," one of them said "what a great song, am I right?" The clapping of the school was the answer he got.

"Anyway, a new year has come, and with it new upgrades for our game."

The other twin started talking "first of all we now have the option of selling you the duel disks and new cards to play with." The idea was simple to execute, Harry had GAI change two small runes into the new runes he created on each of the disks, and because those runes are made of small equations, they can't be copied, so he doesn't fear a copy cat would steal their invention.

"Secondly, we have a starter's pack for all the icky little first years, gave them to our dear charm's Professor and last year's second place in our championship- Professor Flitwick."

The professor rose only to bow dramatically, earning giggling from some of the younger students.

"And lastly," the first twin said "after seeing and hearing the song we have one request," he stoped for a dramatic pose "make a song for card dueling! If the band does it we will make a spacial cards for you!" The last bit was to take suspicion off the twins when the song about dueling came out.

THE NEXT DAY

Seeing fake Moody changing Malfoy into a ferret, Harry understood why Professor McGonagall is so upset.

As he was in the middle of learning changing a man into an animal, even if he does it differently and wandlessly, Harry knew the amount of control one needed to do something like that is much higher then other kinds of magics, doing that while angry? It's a recipe for disaster, which only made the man even more impressive and scary to deal with, especially as the man was in Azkaban before becoming a prisoner in his own mind for years.

Leaving quickly after making sure the man was as talented and scary as he thought of him as.

Reaching the ROR, Harry came in.

"I'm sorry I'm late."

"We are very disappointed in you Harrikin." A twin he said to him with a serious expression "I think my less handsome twin was a bad influence on you."

"You are mistaken my less funny brother, it is you who had influenced badly on our young friend."

"Actually the one who caused me to be late was our DADA Professor and the rumors about him."

"Really? Do tell!"

"Well, according to what I have heard, the Professor is about to teach the upper years about the unforgivables and especially about the Imperius, including how to resist them by casting them on the students.

Harry's three friends become deathly pale from hearing that.

"We-Well, it's important to know how to resist it, and it's better to experience it in class, right?" One of the twins asked, yet it wasn't Harry that answered, it was Luna.

"No, it's worse." She whispered.

"What? why?!" The other twin asked freaking out.

"While it is better to a select few, mostly students who has at least a minor skill in mind defense to experience it for the first time against someone who doesn't try his best, those who do give in to the curse will have it harder to defend against it on the next occasion, while those who didn't experience it might be able to refuse orders."

"You mean, if the Professor curse the class and someone who couldn't resist is ever cursed again...."

"They would be unable to defend themselves."

"SO WHY DO IT?"

"I don't know why, but as he got the headmaster's permission it doesn't matter." Harry said "What does matter is to prevent it from affecting our friends negatively, and for that I need to know, do good are you in Occlumency?"

Since Harry and them became close, Harry has given the twins his book about Occlumency making them study the subject.

"We can stop Snape's intrusions and create simple mind traps."

"Great, you need to teach the first step, the one about cleaning your mind to all of your friends, it is the basic way to defend yourself."

In fact, while Harry was glad more people would come out of this class unharmed, he didn't really want more people learning about Occlumency, he felt that having more knowing about that kind of magic them there already are can create more trouble then it's worth, as obliviating people would become harder, yet he also hoped to level the field between muggleborns and purebloods.
