After thinking it over briefly, Voldemort temporarily abandoned that option.
He felt it would be too abrupt and disrespectful to the Director.
Besides, if that really was the Director, approaching him like this carried a certain risk.
"I'd better ask the Slytherin family first."
Voldemort pondered this, then turned and vanished.
The Slytherin family was not one of the Sacred Twenty-Eight Pure-blood families. Although they constantly claimed to be a family of Pure-bloods, that was hardly a convincing answer.
"Not every Pure-blood family is listed in the Pure-blood Directory. The Potter family, for example. I think we were excluded by the author just like them."
"And there are mistakes in the directory, too. Take the Ollivander family, for instance. The mother of the current wandmaker was a Muggle, but they were still included in that shoddy book, full of holes as it is."
Wizards from the Slytherin family often disparaged the Pure-blood Directory like this to express their displeasure and make excuses for not being included.
But in truth, most families knew they were not Pure-bloods.
That was because a well-known episode in the Slytherin family's history had exposed the secret of their bloodline:
