What if Harry Potter made it to the Dursleys, but never made it inside? Baby Harry Potter is stolen away in the night and raised far from prying eyes and pesky muggles. Born a Potter, raised a Black, the Wizarding World won't know what hit them when he finally appears at Hogwarts. Mostly canon compliant through the end of PoA.
"Now, remember your upbringing." Aziah could only roll her eyes, "Yes, yes pureblood etiquette, uphold the family name, of course of course." She turned to stalk of towards the train before being stopped by her mother. "And Zia? No boys." The war is over and the next generation swarms Hogwarts, with its very own mini Marauders, silver trio, quidditch scandals and boy drama.
