Sirius woke up to the inevitable stare of his baby brother's portrait.
"I have a story to tell, but I need you to be in the room with Grandpa, yourself, and Harry," said Reggie.
"Right," Sirius got up. Reggie added in jest. "Azkaban chewed you and spat you out, plus you look like a revived Inferius,"
"I'm pretty, and you're still jealous," said Sirius.
Regulus laughed and said, "Yeah, stop bragging,"
In Lord Black's study, Regulus said, "Grandfather, I want you to summon Kreacher please."
Lord Arcturus nodded and followed instructions. A moment later, Kreacher replied, "Lord Black called Kreacher,"
The voice from the portrait said, "Kreacher, I asked my Grandfather to call you. Grandfather, a few days ago, you said everyone has a story to tell. Now, I ask you to order Kreacher to tell you of my closing moments and my last request to him."
Kreacher began trembling, and his eyes filled with tears. Lord Black stared at the house elf and then at his grandson's memory in the portrait.
Lord Arcturus could tell that his heart, once more, would end up in pieces. Sirius was pale, and Harry's eyes became hard. Lord Black knew that ignorance was bliss and that blissful state was about to be blown. Well, better now than never. "Kreacher, tell me what happened to Regulus, his death and his last request,"
Kreacher lowered his head, and spoke in a broken voice, "Master Regulus was ordered by Mistress Walburga to take the brand of that half-blood snake faced troll, and to be a house elf himself. By binding his magic, the snake-faced man had access to the Black Library, but the snake-faced troll couldn't touch the books. Rather, snake-face made the master read to him. The half-blood troll learned that the magic of House Black cannot be given by reading. It sounds like goblin talk. At last, the snake man decided to punish Master Regulus with the pain magic due to his failure. Later, the snake-man became obsessed with creating a trap, a device to kill those who tried to take away a treasure from the snake-man. The snake-man needed to see if the trap was good. He ordered Master Regulus to supply his house elf to test his trap. Master did, but after the snake man left Kreacher to die because Kreacher drank the poison, Master Regulus called Kreacher back, and Kreacher obeyed. Master Regulus healed and cared for Kreacher until Kreacher was able to stand. Master then ordered Kreacher to take him to where the treasure was. Master drank the poison in the basin and then took the treasure. Master gave Kreacher the snake man's treasure and placed a piece that seemed the same as the snake man's treasure. Master ordered Kreacher to leave and destroy the snake man's treasure. Kreacher begged Master Regulus to return with him. Master cried and said that Kreacher would be carrying dead weight. Kreacher returned to Grimmauld but not before looking back and seeing Master Regulus being pulled into the depths by Inferi hands,"
That was as far as Kreacher and Sirius could take as the tears and guilt choked them. Lord Black cried with one arm covering his face. Sirius felt as though the waves of loss and pain were unending. Jamie observed each of the persons in the room. The grandfather, his godfather, and that poor house elf suffer for a piece of shit with a snake face.
"Mister Kreacher, what's the name of the snake face man?" asked Jamie/Harry.
Kreacher turned to the child, and while he could insult and not reply, he knew that the child was in the presence of Lord Black, so he turned his eyes to Lord Black. The man in question nodded his agreement, and Kreacher said, "Voldemort,"
"So, that's the same arsehole that killed my parents, am I right, Sirius?" asked Harry to Sirius.
"The same one," said Sirius.
"Regulus died opposing that bastard, and so did my parents, right?" asked Jamie.
Lord Black nodded and then turned to Kreacher. "Kreacher, do you still have Voldemort's treasure?"
Kreacher nodded and appeared and disappeared in a flash. When he reappeared, he had a pocket watch. At least, that was Jamie's first impression. Lord Black had the item placed on his desk. The darkness the item emanated was oily, and it tried to gather around Lord Black. Lord Black, however, projected a shield in a navy blue-black aura. His Lord's ring radiated the dark light and enclosed Sirius and Jamie. Lord Arcturus smiled and denied, "That absolute piece of faecal matter, actually divided, huh, he had the nerve to create a Horcrux. Oh, that bastard fucked with the wrong family," he raised his sight and was furious at Regulus.
"And you! You stupid boy! You could have come back before being branded as cattle by that murdering lunatic, but no, just like your brother here, too proud or just stupid or both. You boys turned as hard-headed as I was in my youth, and now, I get to scold your memory. Sirius lost years of freedom, and Harry lost his parents. Hear my words. I will not waste more time lamenting my regrettable management of this house. Sirius, Harry, get ready, Anima, help me get ready. We will be going to Gringotts and Kreacher rest because when we get to Gringotts, I want you there to witness how we Blacks keep our promises,"
Sirius and Jamie/Harry trembled at Lord Black cursing and ordering up a storm. Both ran as though they were on fire.
Thirty minutes later, Lord Black and his family were stepping into the office of the goblin administrator of the Black account inside Gringotts. It had been at least two decades since Lord Black visited his office with his family. The goblin administrator was in shock.
That day was quite informative for Jamie/Harry. For example, Lord Black paid the goblins to locate all of the Horcruxes and destroy them because a member of the Black family had sacrificed his magic, life, and blood. Blacks and goblins shared a view. Blood for blood was reason enough to destroy an enemy.
Lord Black asked for one more favour. When all of the missing Horcruxes were in one place and about to be cleansed, they called him, Sirius, Harry Potter, and Kreacher to stand witness to the destruction of the vile things.
Jamie/Harry agreed with the idea and said, "If by destroying Voldemort's treasures I get my family avenged, then do it. Let the goblins find and destroy the weapons and enemies of my kin. My parents deserve justice,"
Sirius said, "I want the goblins to investigate the finances of the Dursleys and Albus Dumbledore. Custodian goblin, you can hire a third party for the mundane inquiry. In the meantime, Harry and I will talk with the administrator of the Potter accounts and have the will of the Potters read,"
"I want to thank the executive goblin for doing a good job," said Jamie/Harry.
Sirius and Harry continued to the office of the goblin administrator for the Potter accounts.
Harry took the heirs' test and provided proof that he was Harry Potter. Sirius had enough evidence to turn the Wizengamot on its head after the reading of the Potters' will.
Sirius was going to get his case cleared. Then he was going to step into the role of Lord Black, but only because Harry needed to learn how to be a despicable bastard with the last name Black. Harry was his sole heir.
When Lord Arcturus Black learned of the motives his grandson had for becoming Lord Black, his ideas to restore and reshape the arse of the entire Wizengamot, the man smiled again. He wanted to be there when his grandson walked in with his heir behind him. Yes, Merlin, yes, he felt alive again.
