In an opulent house in the wrong side of London, there was the grand house of the ever pure Blacks. Not that you would know that it was opulent from the outside; the walls were blackened and the garbage littered outside. Which was just the way the Blacks wanted it. No need to attract unwanted visitors to come or worse muggles.
Mrs. Black stopped at the edge of the stairs on her way to the guest room. An attractive thirty somethingish witch, her expression at the moment was one of annoyance and a hint of worry. She adjusted her tight skirt, patted her hair in place then entered on her husband Orion.
"Ah, Wallburga! The moon tonight will be jealous of your beauty!" exclaimed Orion, standing up and surveying his wife with appreciation.
"Orion" she snapped "Did you know your sister invited another guest to the sioree? I've catered for only 57 people. Really, Elisa is just insufferable sometimes..."
"Yes, I know I'm so sorry, if I knew sooner I would've told her not to" said Orion movingly, unmoved by her ignorance of his compliment. "Kreacher!"
The house elf named Kreacher popped in the room and although bowing lowly he was smiling, his ears covered with soap bubbles. "Yes master?" he crooned.
"Add one more place to tonight's dinner."
"Certainly, master."
"Are the children ready?" demanded Wallburga.
"Master Sirius is, mistress. Master Regulus is just about to finish his bath."
"Good" said Wallburga, slightly less angry. "Please see to it that they are presentable."
The house elf bowed again and popped out of the room.
Wallburga moved and sat next to her husband.
"Do you know about this guest?"
"Yes, well, I've heard of him. Excellent chap, it seems. He just donated a rather large sum to the Merlin Museum. Said he wanted to preserve pure blood history." Said Orion approvingly.
"I've heard he's very zealous about ancestry and pure blood"
"Just what we need at the moment. If we have any more restrictions put on us for the safety of the muggles, we might as well move to Azkaban. Apparently it's true that a ban will be made on flying carpets."
"There goes our seaside trips with the children" said Wallburga bitterly.
"Yes well, this man isn't playing around, I think he's got some really good ideas" muttered Orion but was interrupted by the doorbell. "Our guests have arrived Wallburga, let us not keep them in the cold." And he took her hand and went to the hall to greet them.
