Hey everyone,
So this story, alongside two others have been dominating my mind for the last two months and I felt I just had to put them on paper if I wanted to make sure I could properly focus on the stories we still have left. And let's face it, that is exactly what this whole series was made for; to make sure I can clear my mind of potential ideas.
Okay, have fun,

Preview #9
Codes And Trust

7th of July 1995
Grimmauld Place
Sirius Black's POV

"Well, the Order is officially together and we actually already have a few new members. And by Merlin, am I glad Remus has better common sense than me and Albus combined. I really should have realized the error in the man's plan and I am so glad I went to my best friend first. I just hope Harry didn't realize this problem."
Goes through my mind while I listen to Albus giving a bit of an opening speech, which amuses me as the man seems to think that there is actually no difference between his Order of the Phoenix and the students at his school, yet this fact also worries me as it makes me wonder whether or not he will take us and our ideas seriously.
"Who am I kidding? Albus himself desires unity more than anyone else. He told the three schools so himself at the end of the year if I have to believe the twins." And this makes me look up away from the table we are conversing at and over to the door and the staircase behind it that leads to the rest of the house we are at.

If there was ever a place I never thought I would return to – other than Azkaban – it is definitely this place, yet I won't deny that this fact will protect me from both the Ministry and Voldemort, yet the idea that that bastard Wormtail has told Voldemort of my Animagus form angers me as it limits my freedom even more.
"I need to stay safe. Harry needs me and he can't be helped if I get in danger, hurt or even die. The memories here won't be as bad as the prospect of any of those things happening. I got to survive Azkaban and it has the same effect as this place will have, so I ought to be just fine. Harry can really start counting on me now."

This goes through my mind as I focus back on the meeting, yet just when I do, does a sound I would rather not hear sound before I get shocked as instead of the old and withered House Elf I was expecting, does a hyper-active looking House Elf appear besides me, shocking others as well, some of them drawing their wands.
"Lower your wands. Dobby, what brings you here?" Albus asks and I suddenly remember Harry telling me about a House Elf under that name in one of his letters and the House Elf then speaks and says: "Dobby has letter from Harry Potter sir for Harry Potter sir's doggy master." And the name he gives me makes me snort.
"Oh well, I am sure that letter can –." Albus says, but then stops when he sees Dobby shaking his head really wildly and says: "Dobby has already waited. Dobby wanted to make sure Order of Headmaster Phoenix was underway before Dobby gives the letter to Harry Potter sir's doggy master." And this seems to shock Albus.
I, in the meantime, smile at the friendly, helpful little thing and ask: "Is there any reason you wanted to wait for this, Dobby?" And the House Elf turns brighter than a Lumos Solem as he says: "Harry Potter sir's Doggy master just read letter and then Harry Potter sir's Doggy master will know." And with that I take the letter and read:

Dear Rat Eater,
It's been a while since my release from the Hospital Wing.
How are your friends doing?
Are you celebrating a House Cup Victory?
Please tell me you're not visiting the lake side at night.
Don't forget your essay,
The Treacle Lover

"That letter made no sense whatsoever! Why was that stupid House Elf so adamant in wasting our time exactly?" Snape then snarls, yet I smirk at him and say: "For shame, Snape. You're a spy, yet you don't even recognize a coded letter when you see it?" And the man's eyes widen before I focus back on the letter and read:

Dear Sirius,
It's been some time since you left.
How is the Order doing?
Did you gather many members?
Or did they try and hand you over to the Dementors?
Write back, please,
Harry

Everyone looks shocked at this and I smirk at them, while part of me feels horrible at the fact that Harry did realize the problem with Albus' orders for me and I say: "Harry is smarter than we give him credit for. He made his letter incredibly cryptic and even send it with Dobby instead of Hedwig to keep it from being intercepted."
And everyone looks at each other before I summon some writing equipment of my own and when Albus tries to stop me, I say: "Albus, my godson is worried about whether or not I still have my soul. I must and I will comfort him before anything else." And the man sighs before I charm my quill to write for me and say:

Dear Patronus,
I wish I had a time turner.
The Moon gathered my friends together.
I have also found a better cave to sleep in.
Essay? Is your mind too full for your heart to take?
The Firebolt

And when I see everyone look at me confused, do I roll my eyes before I recite: "Dear Harry. It's been too long. Remus did my job for me. I found a much safer place than before. Write back? Don't you be remiss in that yourself. Sirius." And the others all nod before I wrap up the letter and hand it to Dobby with a pointed look.
"No waiting, Dobby. Instant transport, no matter what. And remember, you can only be called by myself, Albus and Harry. Nobody else." And the Elf nods excitedly before he leaves with another tell-tale pop and I turn back to the Order as I ask: "Weren't we discussing what the kids are and aren't allowed to write Harry?"
Everyone nods and I turn back to where Dobby was just seconds ago as I shrug and say: "Well, telling him too much is still a bad idea, but – why not have the kids send their simple letters – letters about school, grades, their pets, things like that – with Dobby? I know it will probably offend Hedwig, but – it's safer, right?"

"That depends. Are we sure we can trust that little thing?" Alastor asks and while I can't fault his increased paranoia, does Albus say: "Dobby is a free elf that works for Hogwarts and who hates his former employers, the Malfoys. He goes above and beyond to see Harry safe. He is most certainly a reliable little help."
At this his oldest friend humps softly and I say: "Alastor, if I have to believe one of Harry's letters, that little bugger was willing to steal from Snape's personal stores just to provide Harry with the equipment necessary for surviving the Second Task." And this seems to earn the scarred man's respect before another pop is heard.
"Damn, that kid writes quick." Kingsley mutters and I smile at this as it must be the fact that Harry can now write me whenever he wants to that inspires the boy's desire for fast writing and I take the new letter as I say: "Last letter this meeting, Dobby. Please let Harry know that when you send my reply back." And the Elf nods as I read:

Dear Shrieker,
Dogs are pets, because they are loyal, while wolves are supposed to have packs.
But if the Moon howls in the third, then silences himself for fourth, he should not gain a pack before fifth.
Howl the truth or howl not at all.
The young caster

Yet this utterly confuses me and I think: "What the heck does this mean?" And I look up, yet no one seems to have any more clue than I do as I turn back to the letter and suddenly notice something. "The numbers. Third, fourth, fifth? Remus, did you tell Harry something and then do the complete opposite?" And this shocks my friend.

Hey everyone,
So what do you think of this idea? I always thought that Dobby could be of good use during war time and kind of wish this was done in canon as it would have made Harry's fifth year a lot better. Also, the Trust part of the title? Yeah, that will be something that Dumbledore will have some trouble with over the story length.
Also, this story will probably have some bad Molly Bashing, some constructive Dumbledore bashing and some utterly destructive Snape bashing with Sirius being more perceptive than some people – especially the canon verse – give him credit for as he will know how to read people better than they will expect him to.
Now the next two previews will both revolve around fifth year, yet one of them will have Harry focus on Sirius and will have him thinking quite dark and with lots of concern for his guardian, whereas the other – well, it will make the Ministry look even darker and more horrid than Voldemort during war time.
Have fun,

The Prophesy is a fake, but not in the sense that it can't come true, just in the sense that it is not a prophesy created by the Oracle of Delphi

Prophesies not created by the Oracle are considered wrong and dangerous as they put the ones hearing them under a compulsion charm aimed at making sure they come true, regardless of the consequences or the conscience of the ones hearing them.

Because Snape only heard part and because he only relayed the half that he heard, did the prophesy only halfway affect them both, yet this lowered all inhibitions they had before hearing the prophesy, thus Snape cares no more for the fact that he is hurting Lily's son and Voldemort loses all loyalty he has to his followers.

While Harry is not compelled to fulfill the prophesy, is he still the only one who can actually the destroy it, though destroying the orb won't destroy the prophesy itself as it will not break the compulsion spell it has over Dumbledore, Snape and Voldemort.

After being freed from the compulsion does Dumbledore change tactics and so does Voldemort, making it so that he tries conquering the Magical world through Politics, yet Dumbledore bests him time and time again until Voldemort, in his rage, kills the man, only for Harry to inspire the Wizengamot to curse him into the Next Great Adventure.

Harry decides that he will honor House Potter by honoring the traits of his mother that made his father love her. He becomes a true fighter for Muggleborns, yet becomes more active in this role than Dumbledore and creates special protection laws as well as laws Muggleborns will have to listen to if they wish to live in the Magical World.

After Graduation Harry takes over and revamps the Muggle Studies class and uses it to educate both sides of the world – Muggleborn and Pureblood – and helps them integrate in each other's worlds.

Harry's lessons get taken over by the Ministry and the Magical world slowly but surely starts to show itself to the Muggle world, integrating the two worlds into one.

Epilogue: Harry's son goes to Hogwarts and his daughter to Eton (or another prestigious High school). His wife/partner: up for decision.
