There was a reviewer on 'Pacific Academy' who wanted to know why there wasn't a Fidelius charm around Pacific Academy.
the answer his here in the chapter.

The team of cursebreakers and aurors from the United States, crawled through the overgrown bushes that hid the old building from the rest of the world. Using a few very clever tricks, they had disabled the wards around the shack, where one of Tom's little treasures was waiting. One witch moved her wand and cast a few detection charms with it. "It's all clear on the outside"She said to the leader who nodded and motioned to everyone to stand up.
"How's the inside?" Asked Kingsley Shacklebold as he adjusted his workrobes. At the end of the first wizarding war, Kingsley Shacklebold had been assigned as a auror, but with many 'noble' pure blood wizards and witches looking for a job, Kingsley was quickly cast aside, in favour for a 'noble' wizard of 'excellent' breeding. Looking for work, Kingsley responded to a advertisement that told him to head over to the ministry of magic and grab a portkey to the United States for 'freelance work'.

As he arrived, Kingsley soon found out that he would work with a team of hitwizards, to arrest a dangerous criminal. Having lost his entire family to death eaters while he was still at Hogwarts, Kingsley had developed a healthy dose of anger towards anyone who was thinking he was above the law. While the criminal wizard had hit most of the hitwizards with strong spells, Kingsley had used a disillusionment charm and got behind the wizard, who was gloating about how he had defeated the sixth team of wizards that was sent after him, when Kingsley hit him in the head with his fist, and after that, Kingsley just hit the wizard more and more, until there was nothing left of the man's face, but a bloody heap of flesh and blood.

Kingsley understood that day that he had a special power, a power he had no control of. Thanks to the Auror office and the department of magical education, Kingsley entered Pacific Academy and spent two years learing about his power that made his magic and muscles increase in tenfold.
Now Kingsley was a respected member of the auror office, and he was being trained to become the second in command of the auror office, when the current leader resigned.
"The inside is still cursed beyond anything we've seen" Said the witch who held her wand still above her head. "I'm detecting a massive lightning grid with enough power to shoot thirty lightning bolts at anything that moves. Beside that I'm fairly sure that the other curse that is in there, is an old variation of a confounding curse. It makes you, whatever it is, to place it on your body and hold it close."
"Okay" said Kingsley as he stood in front of the door of the old shack. "Tell Lisp to bring forth the snakes we found."

While Kingsley and his team were working to capture the last of Tom Riddle's horcurxes, Harry was running the obstacle course that several teachers had set up for him and the girls. According to the seer in the tower, Maria of the eyes, a terrible accident would happen to Harry and if Harry didn't survive it could mean the end of the world. For that, Harry and his girls were taught advanced tactics, spells and while not perfectly legal, how to use and maintain muggle weapons. While they had some experience with holding guns, after all Luna's signature weapon were two guns, it was still getting used to the noise of the guns.

"How are you doing?" Asked Harry as he looked back. Ginny and Luna were able to keep up with Harry, but Hermione had some difficulty with the tempo that Harry had and while she was adapting to Harry's tempo, she prefered a slower tempo. " Don't worry Hermione. We'll soon be done and you can enjoy a lesson from professor Estill where we'll have fun with charms." Said Harry as he kept an acceptable pace. Hermione nodded, not trusting her voice as she was panting heavy.
Ten minutes later, Harry and his girls had cast freshing charms on each other, while Hermione took an extra shower and a small dose of pepper-up potion that her mother had placed near her book bag. Feeling ready, the four students joined the rest of the seventh years in the charm classroom, where Professor Estill was talking with the headmistress.

"Students, welcome to a new charms class. Today we'll be discussing the Fidelius charm." Said the professor, to the amusement of the students. "Please take notes as this charm might be asked about on your OWL."
Harry smiled as Hermione took out pen and paper, and started to write down anything she knew of the Fidelius charm. Harry took out his charms book and looked up the charm in the index of the book. Frowning, Harry held up his hand.`Yes mister Potter?" Said Professor Estill.
"Professor. The charm isn't listed in our book." Said Harry as Hermione looked up from her work.
"True, the Fidelius charm is not listed in your book, as 'Charms made easy' is for the students who work towards their OWL's. If you succeed to get an O or EE for your OWL charms, then you'll need new books. In 'Charms for Advanced' You'll find the Fidelius charm that we'll be discussing today."

"Right. First of all. What is the Fidelius charm?" Asked the professor. Several hands shot up in the air, including Hermione's. "The fidelius charm is a charm to hide a location inside a person's soul. The person who had the secret stored inside their soul, is called the secret keeper" said Hermione as she was given a turn.
"Two things, miss Granger. Do not quote what any book in the world has written, but use your own words. Second, while the main use of the Fidelius charm in used to indeed store a location inside a person's soul, there are also wizards that use the charm to hide a object or a personal secret." said the professor. Hermione nodded, as she started to write again.

"I'll give you one example. You will find the pillow of the headmistress on the headdesk of the charms teacher" said Professor Estill, and the whole class gasped as the pillow of the headmistress became visible. "Wow" Said Harry. While he was a seventh year now, magic still was very magical.
"Wow indeed" said Ginny as she started to write down what the professor told the students.
"Several older students have asked me this question many times. 'Why isn't Pacific Academy not under a Fidelius charm?' The answer is very simple. Because of the special way we hide Pacific Academy, we don't need it. How many hostile wizards have entered pacific Academy in the last hundred years?" asked the professor.

Harry's arm shot up. "Four wizards so far ma'am" Said Harry, still remembering the wizards that tried to grab him to place him under Dumbledore's command. "Correct mister Potter. Because of those wizards, we have taken extra care to protect our students but still not placed a Fidelius charm around our school. Can anyone tell me why that is?"
Only one hand went up. "Yes miss Granger, do you know the answer?" Asked the professor.
"Ma'am, the reason is that a Fidelius charm around Pacific Academy will be incredibly hard to do. Every soul who has entered Pacific Academy, and knows of it's location will know that something has happened the moment that they can't remember where the academy is. The power to hide the academy will be enormous." said Hermione as she tried to explain it in her own words, instead of just quoting the book. "Correct, miss Granger. One golden coin to you" said the professor as she levitated one coin to Hermione's table.

"As miss Granger already told us, hiding the academy will take so much magical power that sixty full grown wizards and witches with all their powers, won't even make a tenth of the secret hold. A second reason is that the secret keeper will have to be someone who can be trusted. That would be either the headmistress or the deputy headmistress of Pacific Academy."

"Thousands of people know the location and existence of the Academy, Hermione" said Ginny as she tried to tell Hermione that a Fidelius charm was out of the question. Harry ignored Hermione and Ginny while he was working on Transfiguration. While Professor De Bruin had told them that they wouldn't be studying the Animagus transformation in detail after they had sat for their NEWT's it was 'advised' to study the introduction of the subject, as it might be in their Transfiguration OWL. Harry hated this. He hated the secrets that the teachers held for him and his classmates. Always hinting that there could be a 'advanced' question about some subject that they didn't discuss. Even more that annoyed about the teachers, Harry had become so angry at the news from Professor Summers that Alan Richards would place a dampenign spell on them to block out the so called mind-speak between Harry, Ginny, Luna and Hermione.

Harry had flat out refused and even the headmistress couldn't change Harry's mind. "I don't give a damn about what you think. I can promise you that we will not cheat" said Harry before he stepped through the door of the headmistress office. "If you don't trust me, and in extend Ginny, Luna and Hermione that we won't cheat, then I won't trust you anymore." Said Harry as he left, his phoenix singing a song that filled the teachers and doctor with a sence of shame.
"Harry's right" Said Evelyn as she looked at the door where Harry had passed through. "We pride ourselves to be trustworthy. What image do we give to our students if we break that trust with Harry and his girls?"
"The community will not allow Harry and the others to speak with their mind to each other, in the middle of the OWL's" said Alexandra as she tried to find a way to get Harry to cooperate.
"Then why don't you tell that Harry will loose his trust with us if we continue with this plan?" Asked Alan as he imagined casting the dampening spells on a pissed off Harry and girls.

"Mister Potter, do you have a moment?" Asked a voice that sounded like professor Vector. "I'm sorry Professor, I don't have the time right now" Said Harry as he looked up from his transfiguration book, only to have his mouth fall open as he took in the sight before him. It wasn't Professor Vector at all. It was his sweet Ginny, looking at him with hope filled eyes. "Harry, Please come to bed. You've been studying for so long now" Said Ginny as she gently lifted Harry from his desk and placed him in bed. Harry had only eyes for Ginny's underwear. A velvet red bra held Ginny's breasts restrained, while she had the cutest red string covering her lower body.
Ginny smiled. "Hope you like this Harry. I've got something planned on your birthday in a few months time." Said Ginny as she slowly pulled the blanked over both of them. Hermione was at her Parents room, and Luna was in the hospital wing. So they had some time alone, just them two together.

"I like the sound of that" Said Harry as he slowly started to fall asleep, with Ginny on his side. Ginny smiled as imagined how Harry would react when she would show him what was under her underwear in a few months time. Having that Happy thought in her mind, Ginny placed her arms around Harry and fell asleep, holding her arms around her man, her best friend and her confidant.
