Mysterious thing, Time. Powerful, and when meddled with, dangerous.

Harry Potter wasn't sure what he was doing was right, but he didn't had any other chance, did he? It was hard to tell. Sirius Black needed to live and for that he was ready to do something, he had done once for saving Sirius.

Time-travel

1989

It was hard for Harry to rewind all this but he knew that he had to do something to save the person whom he considered as his own father. A blonde girl with silvery blue-grey eyes clutched Harry's hand and muttered, "Brother, are you sure about this?"

A nod from Harry was enough for the girl to take a deep breath and continue as nothing happened.

"Will you save mummy too?" asked the girl and Harry nodded, "No, more losses for us, Luna. We will save all the people we can." And Harry Potter meant it.

Gringotts

"I would like to do an inheritance test" Harry looked at the goblin who just raised his eyebrow looking at him and Luna and nodded, "Very well."

Going straight towards the room followed by Harry and Luna, Sharptooth picked the knife and a parchment.

"It says that I am heir to four houses, I was never told about this?" Harry frowned.

"It is because you're heir and not Lord, heir Potter." Sharptooth replied analysing the boy infront of him.

"Err…. Can you explain what is the difference between them?" Harry's frown deepened.

"Of course, heir Potter. As Magically first you see that you're confirmed as heir Potter and heir Black. Potter and Blacks are old pure-blood families and for them to remain pure there are certain terms a person should be met. One of them is being a pure-blood, which you're not. Second, you should be well-versed in family magicks of the houses to acquire the lordship. Third, a lord is the powerful member of the house, one who cannot be challenged by any other member of the said house. Fourth, a lord should remain at the main house which is built by their ancestors after taking the lordship. These four conditions are mandatory for all the pure-blood houses. Other conditions are set by the respective families to maintain the respect and power they have in society."

Sharptooth paused as Harry's frown deepened more and he nodded, "Why being pure-blood is necessary?" Luna piped in and the other two occupants looked at her and Sharptooth gravely stated, " Pure-bloods magic is different from other peoples magic. It's like in muggle they say, that the child is stronger like his father or hardworking like her mother. A child at the time of pro-creation has the magical ability of both his parents but more of the paternal side, like the Blacks are well-versed in dark magic while Potters have the quality of transfiguration and flying ability. Now, if one of the parent blood is lesser than the other then it will result in vanishing the family magick." Sharptooth replied and Harry asked, " I'm not good at transfiguration but my father was and grandfather too." "As I said when your father marriage a muggle-born witch the ability of your family magick vanished to a certain percentage of how much powerful witch your mother was."

"What about this conquest title?" Harry carefully examined the parchment.

"According to the confirmed right of conquest title, if you want you can withdraw the money and claim on any property related to the Slytherin and Gaunt vaults and properties, though seeing the accounts we have, Gringotts doesn't possess any vaults in the name of Slytherin and Gaunt, you cannot claim any money from them. But you have the right to access any remaining property the two houses have. Moreover, no security of the Slytherin and Gaunt properties can harm you as you had defeated their heir."

"Voldemort?" Harry questioned to which Sharptooth nodded.

"Then this life-debt, I don't remember saving any Prewett?" Harry frowned as he suddenly remembered something Ron once mentioned about his uncle's name Fabian and Gideon Prewett.

"You saved Ginny's life in your second year and the Prewetts are relatives to Mrs Weasley" Luna pointed out.

"How did I get the Lestrange Vault?" Harry rubbed his eyes if he was seeing it clearly or not.

"It got under Lord Black's name after their eldest daughter Bellatrix Lestrange neè Black got incarcerated in 1981. As a violation of the marriage contract terms."

"I want to head the Black family so, what shall I do for it?" Harry asked

"You have to change your name first according to the Black traditions, then you have to disown yourself from Potter family and your muggle-born blood to make you eligible for new magic to run in your veins, then you have to bring seven strands of hair, seven drops of blood, seven personal items of the person whose hair and blood you have collected and it will take seven hours to perform the ritual, currently the rate is 1500 galleons per hour." Sharptooth finished.

"Err… isn't it a bit costly?" Harry looked at the goblin who ignored him and quietly they went out from there.

"What are we gonna do now?" Luna looked at Harry who muttered he has to find out of Sirius.

Grimmauld Palace

"Damn I'm unable to find anything" Harry shuffled through Sirius room when Luna hopped in.

"I got this Harry, see. These were on the other room." Harry frowned as he looked at the items, they were more Slytherin, one house his godfather hated the most.

"It should be of Regulus", Harry said searching for some of Sirius hair, " and a son of the Black family who was loved and respected by everyone and whose son's heirship will never be challenged." Luna added and Harry paused.

"Regulus died in 1979 and if you are to born on the same year than congratulations because it'll be a perfect and good plan, secondly you can act as a clueless orphan boy who had his father's some memories because I doubt that someone will search through Regulus missing item after watching this house condition." Luna commented making funny faces.

"You're right", Harry's eyes lit up as he looked towards Regulus belongings which were too Slytherin for him.

"Then let's go" Luna chirped.
