Harry Potter - I Became a God at Hogwarts

Astor was confused. He thought his time-traveling experience was already ridiculous enough. But he never expected to become the top student in his grade, causing Hermione to go crazy, and he even felt a little guilty about it.

Astor arrives either in the past decade or so, just before the first two great battles are about to begin. Can Astor stop these battles? And why would he want to stop them? Is it because of Malfoy's mockery, or because of the Gryffindors' contempt?

Astor is no pushover; he won't repay evil with kindness. He will only go to Anning to stop Voldemort for the sake of his friends.

So why does he speak Parsleyan? And what does that have to do with Salazar Slytherin?
