The Scamander-Graves twins are utterly baffled and unimpressed when they are set an assignment to research their family history.

Everyone at Hogwarts knows their family history, anyone can read about it. The twins not to mention all of wizarding society knows the story of Newt Scamander and Percival Graves getting together, falling in love as they helped defeat Grindlewald. They were hailed as war heroes, married and had a bunch of kids and are still disgustingly in love. The story’s old. What’s left to tell?

More than they thought apparently, when it turns out the official wizarding records aren’t wholly…accurate. Things become even more puzzling, and troubling when they return home and find some hidden family documents, not just hidden, but magically hidden, and seemingly magically altered, including their birth certificate. Most of it is normal; Newt is their birth father, but…something is wrong…been changed with the strongest magic wards protecting it.

Why would their parents ward their birth certificate and other family documents? A simple spell should fix things but only makes it worse, when one word slowly immerges.

Grindlewald.

N.B. Feel free to choose the twins names and genders! MPreg welcome.
