As the fortress loomed closer through the dark fog, Harry came to the conclusion that he couldn't really blame the people who had turned against him based on the facts. But the Ministry could have given him a proper trial with Veritaserum and those who had known him for so long should have believed in him.
Harry has already had bad experiences with the competency and adaquecy of the Ministry thus far. Seeing how one of the core conflics I want to exist is a not-evil Dumbledore against Harry due to Dumbledore being for the Ministry and Harry being against it, I'm for keeping this particular end result. This could be the push Harry needs to believe that the Ministry isn't worth the space it's wasting, which, when combined with his new authority and power as the Earl of the North, means that he not only has the motivation to get rid of the Ministry, but the ability to do something about it. Or at least make very convincing and serious threats in the Ministry's general direction.
So this
sentiment needs to stay. And in order for that to happen, Harry cannot be given an unbiased or fair trial. It needs to be clear from the beginning that the Powers That Be are seeking his conviction, and are willing to disregard their own laws to do it.
Considering how Fudge behaved at Harry's 'hearing' in canon, I don't think this will be much of a problem for his actual trial here.
The cell was quite small and was windowless. The only opening other than the closed door was a small hole in the corner which Harry assumed served as a toilet. The thing that startled him was that he was not alone. Another inmate was huddled in a dark corner that the light from the barred cell door opening didn't touch.
Harry decided to be social, even though the other inmate was quite likely insane. He stepped towards his cell mate and took a good look that left him reeling in shock. "Bellatrix Lestrange!"
Bellatrix raised her head and her moist and slightly-dead violet eyes met his. "Black actually. My husband divorced me." She sighed and returned to gazing at nothing in particular on the floor.
"Why?"
"Because I betrayed V-V-Voldemort." she whispered. "I wasn't killed because they thought it would be amusing for me to rot in this hell-hole. Didn't stop them from torturing me though."
To say that Harry was stunned would be an understatement. Why would she betray Voldemort and how had she ended up here without it being all over the newspapers? The second answer was actually quite easy really. Fudge would not want to admit that she had escaped in the first place. Any reports that she had escaped could now be dismissed as false.
Harry elected to sit down next to her. He was itching to know how she had betrayed the Dark Lord, but decided that a little sympathy might get him further in the long run. "Crucio?"
A weak snort answered Harry. "That's nothing." Bellatrix turned towards him and pulled the neck of her ratty dress down a bit further to reveal a mass a red-welted lines all over the skin of her upper chest. After Harry had gaped a moment she let go and sat back against the wall. Now that he looked closer, he realized that the numerous stains on her dress must be blood.
"I'm sorry." Harry said sincerely. She may have been a Death Eater who had tortured and killed many, but he couldn't help but feel sympathetic towards her. Besides, if she had betrayed Voldemort, she couldn't be all that bad. "How was it that you betrayed him?"
She looked at Harry with a bit of a smile. "I sent you all those letters."
"Why did you do that?"
Bellatrix sighed deeply. "I was trying to make up for my crimes. Fifteen years in Azkaban changed my outlook on life. I rue the day that I decided to become a Death Eater. When V-Voldemort broke me out I had no choice to but to follow." She stopped and looked away from Harry. "I'm sorry about Sirius." she said quietly. "I tried to stun him. I didn't know that he would fall through that thing."
Alright. This, I think, will be the biggest deviation from Earl.
In Earl, Bellatrix is here. She confesses to actually not being evil and having helped Harry, identifies a tattoo on Harry's arm that is called a "Warlock's Mark," which is a kind of arcane birthmark that only very powerful wizards have, and uses the Mark to train Harry in wandless magic, which they eventually use to escape Azkaban.
I don't want Bellatrix involved. At all. However, that presents a rather unique dilemma, because the Earl's powers (most of them, at any rate) only work once he gets declared the Earl at the ancient fortress of the North, whose name I can neither remember nor pronounce. Until then, we're dealing with Harry Potter, not Superharry. So Harry needs to be able to escape.
My idea for this is to have a very simple, but very
important deviation. Fudge never gives Sirius his paper.
Think about what that means. If Fudge doesn't give Sirius the paper, Sirius doesn't see Peter disguised as Scabbers. Without seeing Peter, Sirius has no motivation to escape Azkaban. With Sirius still in prison and Peter still hiding out as Scabbers, Pettigrew doesn't need to be revealed.
It could be
Sirius that Harry winds up bunking with in Azkaban, and it could be
Sirius who winds up helping Harry escape. How do they escape? Simple.
Sirius teaches Harry how to be an Animagus. Harry picks it up in record time, which is just fast enough for Harry and Sirius to be able to slip away before Dumbledore can come break Harry out by force.
Not only does this create a unique diversion from canon, in that Sirius is still in jail during the events of books 4, 5, and 6, but it
also presents a perfectly valid reason for Harry to become an animagus. It's so he can escape Azkaban.
Now, naturally, Harry can't come into this completely virgin. If he knew nothing about Sirius, there's no way Harry would buy the story. So here's my idea:
Peter is still the one who was there to help revive Voldemort. Harry didn't know who he was at the time, but told Dumbledore about it. Dumbledore, shocked that Peter is not only alive but apparently working for Voldemort, begins to suspect that the story everyone accepts about how the Potters died is not nearly as sound as it seems. He explains his concerns to Harry, explains who Sirius Black is and what he alledgedly did (remember: if Sirius didn't escape, Harry doesn't know about him), and postulates that Sirius may, in fact, be innocent. However, Dumbledore confesses that, at the moment, there is nothing that he can do about it, because even if Sirius
is innocent, there is no proof of it. He could not be extenorated without strong evidence. Strong evidence, like a living Peter Pettigrew. So Sirius has to stay in Azkaban, even though both Dumbledore and Harry believe he is innocent. Dumbledore is also at a loss as to how Peter managed to hide and evade capture for all these years.
Cue Harry getting thrown in with Sirius, who is able to fill in the rest of the blanks. It's Sirius who tells Harry that they were all Animagi, and that Peter was a rat, and it's Sirius who tells Harry that they switched Secret Keepers in secret.
So at this point, only Harry and Sirius know the full truth of what happened the night his parents died, and Peter's hiding place as Ron's pet rat is secure.
Cue Sirius teaching Harry how to become an Animagus, thereby enabling their mutual escape.
This scenario also has an additional benefit of further biasing Harry against the Ministry of Magic. It didn't just have a miscarriage of justice with him. It did it to his godfather, too. The Ministry is so bloated, incompetent, and corrupt that it totally ruined
both of their lives. Harry could have grown up with Sirius, and not the Dursleys. Harry knows it, and Sirius knows it.
This revelation
will not endear Harry to the Ministry. At all. In fact, it will further drive him into the anti modern magical government corner, which is exactly where I want him to be. Harry
cannot be neutral or willing to compromise on this issue. He has to want to bring the Ministry down, period. I strongly believe that this will help in that.
