HP: Harry From The Ancient House Of Black

It had been well known the young Malfoy had been seeing her great nephew Regulus, but apparently his recent death had hit the young witch harder than she thought. 

The shock at seeing her lost love's great aunt was clear on her face and she seemed at a loss for words.

"Regina I hope you intend to invite me in, it is the middle of the night after all."

"Of course Miss Black, of course." She hastily opened the door and seemed as if she wanted to curtsy but decided against it. 

Cassi took the moment to glance at her surroundings and found herself incredibly disappointed. 

Not only had the girl failed to take care of herself but the flat was in disarray. It only increased her belief that her plan would work. 

She sat herself on the lone armchair and signaled for Regina to sit across from her. 

Cassi took a moment to collect her thoughts, allowing Regina to attempt to smooth out the dress she had worn today, and apparently had been sleeping in too.

"I see the fall of the Dark Lord has suited you well," she started sarcastically, noting the flinch at his mention which was just another reassurance. 

"Regulus will be missed by all, and yet his death may serve us well, including you."

"What do you mean?" The hurt that had passed on her face at the mention of Regulus was undeniable, but her curiosity won out quickly. 

She wanted a distraction and Cassiopeia was fighting a grin.

"I'm no fool girl, you wished with all your heart to be the wife of Regulus Black, and to bear his children. Now I'm giving you that chance." Regina looked as if she wanted to speak but the Black woman cut her off. 

"The older Potter boy has been forsaken by his family, and those blasted muggle loving fools have done the unthinkable: they've dumped him on the mudblood's muggle relatives. Black blood runs in his veins. I will not see this happen without a fight."

"What do you intend to do?" Her attention was caught like a fish on a hook.

"We will travel tonight to Little Whinging. We will take the boy back to my home in Berlin. There I have brewed a highly illegal blood-adoption potion."

"It will change everything about him. Even more so considering your blood will be involved. And the blood of Regulus." 

Cassiopeia had always been a paranoid sort, and blood made a powerful ingredient in many potions. 

She had long ago instructed Kreature, the Black house elf, to bring her a vial from every living member once a month. 

It made a rather grotesque collection and yet the bounty she was about to reap made it all worthwhile.

"So," Regina began after recovering from her shock, "The boy will practically be my son? And Regulus'?"

"Yes, in everything. He will look like your child and considering you will help raise him will make it all even more believable. Once he takes the potion it will be as if Harry Potter has died, and your son will be born."

"You've been in hiding for quite a while, it will be believable that he is your son and that you refused to rejoin society considering his father's status during the war." 

She left out the part about the boy's draining magic. First she would save the boy from the muggles, and then she would discover what was happening to him. 

Regina looked on the outside as if she was weighing the option, but Cassiopeia knew differently, one look at the girl's eyes gave it all away. 

A change of clothes and the two had left not knowing that everything soon was about to change.

--------

Cassiopeia had wanted to kill those muggles, and upon hearing freak the first time it had taken every ounce in her being not to use the Cruciatus Curse on the lot of them. 

Only Regina telling them that they were taking away the freak under the cupboard and hastily leaving the house had kept her from killing them. 

They had arrived back to her home shortly after two, the potion was ready save for the blood it required. 

A sleeping spell had kept young Harry asleep but soon the boy would wake and his memory needed a lot of changing. 

The boy was two but no doubt he had some memory of the past two years. But first, he needed a name.

"What shall be the name of your son Regina?"

"Aries Orion Black," she did not hesitate, "It's what Regulus would have wanted."

The Black woman nodded and felt a swirl of pride for the Malfoy girl. 

Cassi entered the boy's mind and slowly she began changing things, replacing faces here and there and removing the incident with the Dark Lord entirely. 

After the potion was taken the boy would already know Regina has his mother, and he would be a true Black. 

She could feel something though, as she left the boy's mind, a darkness that seemed to pull even at her. 

The boy's dwindling magic was noticeable and she had already began a mental list of what she could try to reverse it.

The house elf brought her the potion and the most recent vial of Regulus' blood. 

It was three months old, but a preservation charm made it fresh and the fact that it was recent would add to the success of the potion. 

A few drops and the potion glowed before turning a slight blue. Now it was up to Regina. 

They had spoken of this already and Regina wasted no time pricking her thumb, allowing drops of blood to drip into the now pinkish potion. 

Another glow and the potion turned a pale grey. It was ready. The fact that this potion did not have to be taken willingly was one of the two factors of why it was illegal. 

The second being that once it was taken there was no antidote, and no way to ever know that it was taken.
