Let's just see where the story takes me haha

No harem but it will be a late romance. The love interest isn't decided yet so I will take Fleur into consideration.

Abbott Avery Black Bulstrode Burke Carrow Crouch Fawley Flint Gaunt Greengrass Lestrange Longbottom Macmillan Malfoy Nott Ollivander Parkinson Prewett Rosier Rowle Selwyn Shacklebolt Shafiq Slughorn Travers Weasley Yaxley

The first 'known' Malfoy that came to England was French but that was... idk before 1200 or so AD. Which means Malfoys are still pure-bloods as the list only lists families that are still pure by 1930s. Hope that clears your doubts

No harem

Sacred Twenty Eight were just families that were purebloods till the 1930s, nothing else. They didn't have any notable features outside that... At least not till 1930s

It won't be a potion then would it? As for spells, maybe there are... after all it's a world of spells, there has to be something out there

Not really, it's just 10-11 years on an average. Like you have an age at which you schooling but there are kids who goes early. It depends from person to person.

former

The thing is that there isn't exactly a rule as far as I remember. It's just that main cast was of that age and most wizards are somewhere between 10-11 when they start schooling, the September 1st thingy was never really stated as a rule
