The Waves of Time and Death

Playing with the letter in his hand, Harry has a feeling that whatever is in them is not going to be good or the truth.

The first letter is short and stupid, Ron's style:

  Hey mate,

We're kinda looking for you. You just left and didn't tell anyone, Harry. Mum and Ginny are asking for you, mate. 
Just come to the Burrow and let's talk.

Ron

Harry couldn't help but roll his eyes at Ronald's way of letter. Does he really think I will just go back running to them? They must think I'm beyond stupid.

Hermione's letter was what he was expecting from her:

  Harry,

we've been worried sick! You just left Hogwarts and didn't tell anyone, Harry. Do you have any idea of how concerned we are for you? Mrs Weasley has been crying all day, thinking that you were kidnapped by a Death Eater. 
Are you doing this for attention, Harry? You know how much we care for you. How could you just leave us like that?
We went to Grimmauld Place but Kreacher said you were not there and that the House of Black has a new head. We're thinking Malfoy owns the house now. Kreacher even threw hot water at Ron and me! That little demon.
You need to come to the Burrow, Harry! We are all here waiting for you, especially Ginny. 

Your friend,
Hermione 

"You've always been a bad liar, Hermione", Harry said after finishing the letter. "I can't believe they think I'm that easily manipulated."

Throwing the letters into the fireplace, Harry layed down on the couch, resting a bit after everything he's gone through today.

’Master?‘, Death asked in Harry's head.

"Yes, Death?"

’I'd like to talk about the power we talked about before‘

"The one you said you were going to tell me? Go on then."

’You've seen in your inheritance test, yes, master? Yes, the power of time. You see, Harry, death is never-ending; it can never be stopped. Death comes to all things no matter the time. In essence, death is timeless, therefore, going from one place in time to another is as easy as apparating to the next room.‘

"Time travel? I can travel through time?", Harry asked, a little short in breath, thinking about the possibilities of this.

’Indeed you can. It's one of the powers of the Master of Death. Endless passage through the waves of time."

Harry took a moment to digest what was said. He couldn't help but think about his parents. The possibility of saving them. He could also save Sirius and Lupin, maybe even Snape. The man saved me multiple times, after all, Harry thought.

"Could I go to my parents' time, Death? Save them from being murdered by Voldemort?"

’Yes you can, Harry. You can go and save anyone you'd like to.‘

"But this wouldn't be a different dimension or something like that right? They'd really be my parents?"

’Yes, Harry. They would be your parents, from your timeline.‘

”Wow", Harry whispered.

"I-I think I want to do that, Death. Save my parents, save Sirius, save them from Voldemort. But, Death, would you be able to help me in any way? I don't know if I'm strong enough to protect them from Voldemort. I was lucky he was weakened when we duelled. I definitely cannot go by lucky anymore."

’Of course, I can help you, Harry. I'm your guide after all. I'll be teaching you all should've learnt at Hogwarts and a lot more, to help you in your journey. I can say with certainty that, by the time you're 19, you'll be ready for the travel.‘

"19... That's good. I know it won't matter in the grand scheme of things but I'd like to see my ’friends‘ pay for what they did to me. I wish I could do it with Dumbledore but I guess I'll have to wait for when I'm in the past.

With that said, Harry got up from the couch, in the direction of the library. Death guided him along the way. Yes, he had a lot to learn and for the first time in years, Harry felt excited about the future.

------------------------------------------------------------------------------------

For the next months, all Harry would do was study to prepare himself for his task. Death and he would spend hours in the Black Library. Now, without the compulsions, Harry realised that he actually loves learning new magic. Transfiguration, Charms, Potions, Ancient Runes, Mind Arts, Necromancy and even the Dark Arts. All this new knowledge was flooding Harry's mind at an incredible rate.

Death even showed him Soul Magic, important against the Horcruxes, and his new favourite: Parselmagic. It happens that Harry was actually still a Parselmouth.

’It comes from your mother's side, Harry‘, Death explained to him one day. ’ Your mother was actually a descendant of Gormlaith Gaunt, an incredibly powerful dark witch, founder of Ivermony School of Witchcraft and Wizardry, Lily Evans was a decent from a squib granddaughter of Gormlaith Gaunt.‘

Parselmagic has taken a special place in Harry's heart, being the magic coming from his mother. The few Parseltongue dark curses he could cast were incredibly powerful and basically impossible to overcome, since nobody else alive knew Parseltongue, nobody could produce the counter curses. 

Another thing that Harry loved doing nowadays was making the lives of his former friends an absolute hell.

The Weasleys and Hermione were made to give back all that money they took from him, and a lot more in damages because of their theft.

The Weasleys were basically crippled by this. The twins had to sell all their products and give the money to Harry, Arthur and Percy lost their jobs in the Ministry after the news of what the family had done came out and, the best part, Ronald and Ginevra wouldn't be able to go back to Hogwarts since the family had no money left.

Hermione, going through a similar thing with her parents, since they didn't know she stole from Harry but now they have to help their daughter pay for the money she took from Harry.

The Most delightful moment, however, was seeing Molly Weasley and Hermione Granger being tried at the Wizengamot.

Mrs Weasley was sentenced to one month in Azkaban and had her wand snapped, as well as being forbidden from producing potions for the rest of her life.

Hermione, for her help in the defeat of Voldemort, was given a 'lighter' sentence, by the Wizengamot's standards. However, Hermione herself might as well thought she was being given the Dementors Kiss.

"Banned from holding any jobs at the Ministry of Magic, as well as having your wand detained for 8 years.", Minister Isadora Fawley stated.

"But how can I go back to Hogwarts if I don't have a wand?!", Hermione cried out.

"You'll not be going back to Hogwarts School of Witchcraft and Wizardry, young lady", answered the minister. "Someone so immoral like yourself shouldn't be allowed the privilege of learning at such a prestigious school."

Seeing Hermione's expression when the minister told her that was something Harry would never forget.

’Merlin, I need to get a pensive‘, Harry thought in amusement.

Mrs Weasley and Hermione were then escorted out of the chamber and Harry, using his Metamorphmagus ability to disguise himself as the old self, got up from his seat to leave.

Many eyes were on him while he left, especially the journalists'. The news of the betrayal had reached far and wide in the moths after the war and the people wanted to know everything about it.

The Traitors, now the Weasleys were called by the people of Wizarding Britain and Hermione was simply ignored as nothing more than dirt under their shoes.

That was not the only trial Harry went to, since the Malfoys had been arrested, the boy felt the need to pay the life debt he owed them.

Narcissa Malfoy was released after Harry told the Wizengamot about her lying to Voldemort, which saved the Boy-Who-Lived at the end.

Harry did the same during Draco Malfoy's trial. Harry told the court that Malfoy was forced by Voldemort, under the threat of death, to do what he did. As well as lying to Bellatrix Lestrange and stopping her from calling Voldemort to Malfoy Manor.

Both mother and son went back to their Manor, however, the Malfoy patriarch, Lucius Abraxas Malfoy, was sentenced to Azkaban for his allegiance to the Dark Lord.

Many other Death Eaters were also sentenced to Azkaban as the months went by. Harry, though, asked Minister Fawley to make sure every single person was given a proper trial, different from what happened during the first war. The Minister, as everyone else nowadays it seems, was more than happy to help the Man-Who-Conquered in any way possible.

After the trials, Harry went back to studying, more relaxed now that the Weasleys and Granger were made pariahs in the Wizarding World.

------------------------------------------------------------------------------------

The time went on so fast that when Harry realised his 19th birthday was just a week away.

’I believe it's time for us to talk before you travel, Harry‘, Death told him after he finished his duel with the training dummies.

Harry was now significantly better at duelling, thanks to Death's enchanted dummies. That plus his newly acquired power and knowledge made Harry basically unbeatable. His body was incredibly tired from all the daily training but he knew he was stronger than ever.

The now man was so in tune with his magic that he felt like he could do anything.

"Sure, Death", he answered as he sat down on the floor, still sweating from all the training.

Dark smoke began to appear and solidify in front of Harry. The first time Death appeared in person Harry almost fell off a chair, but after months of it happening, it was easy to get used to.

"Well, Harry, is almost time and I can see that you are most definitely prepared to go to your parent's time. However, there is one more thing you'll need, Harry."

"What is it? I can't think of anything, I've already packed everything I'll need, Death. Books, clothes, and when I get there I'll go straight to Gringotts and claim the Peverell lordship as we talked about."

"Yes, but you can't do everything by yourself, Harry. Even with all you've learnt, you're still in need of help. You must decide who shall help you in your quest to bring down Lorde Voldemort."

"I can't really have anyone in mind though. If I need someone to help me then it has to be someone I'll trust. I could have my parent's help, but I don't want to put them at risk. The only people I know who fought Voldemort are the ones in the Order, and I'm definitely not asking any of them for help."

"There is no need to ask them, Harry. There is someone who can help with not only bringing down the Dark Lord but also with your plans of changing the Wizarding World. You said yourself you want to make a big difference, erase the corruption from the government, protect children who might've been abused like you were, protect them from muggles who, if found the existence of magic, would terrorise every witch and wizard in the world."

"But I don't know anyone like that. I know I'll have to bridge the gap with the Dark Sect but who could help me with this? The only dark wizards I know are Lucius Malfoy and Snape, and the Death Eaters."

"Look around, Harry. Help might be closer than you'd think."

Looking around the training room in Grimmauld Place Harry thought, ’Black Family? I only know Sirius and he hates dark magic. Orion? No, he's influential but I doubt he'll go against Voldemort. Walburga? Merlin forbid.‘

"Wait. You can be thinking about Regulus Black, right? He's a Death Eater!"

"Oh, but he'll betray Voldemort, have you forgotten? A few days after you're arrival, Regulus Black will go retrieve Slytherin's Locket and die in the process."

"So you want me to help him get the Locket and ask for his help afterwards? I guess I can do that. I always thought it was a shame the Black family was basically extinct. But how can he help me afterwards?"

"Regulus Black is the heir of the darkest family in Britain, Harry. The Black's influence on other dark families is enormous. Regulus, as a pureblood heir, knows the inner workings of the Ministry. Someone with that influence and knowledge could help you immensely."

"But he's a pureblood. I doubt he'll want to help a half-blood. He betrayed Voldemort but that doesn't mean he's not a blood purist."

"That's the reason why I'd like to change your blood status. Making you a new person entirely; and being a pureblood will save you a lot of time if the other dark wizards can accept you easier."

"What do you mean 'change' my blood status? How's that even possible? Will I stop being my parent's son though? I'm not sure if I want that if that's the case."

"Yes, you'd no longer be the son of James and Lily Potter. You'd still have a few characters of them, however. You can't build a new life for yourself if you are still Harry Potter. You must leave some aspects of your past life behind. It'd be better for you, Harry. Trust me on that."

Signing as he got up from the floor Harry said "Okay, Death. I'll allow you to make me a pureblood and I'll go help Regulus Black. I'm trusting you on this."

"You'll not regret this, Harry", Death said as he vanished in smoke. A small smile on his lips
