The golden trio

[On this reality, Voldemort doesn't exist!]
Scotland, 95'
You're fifteen, and on this year, you're going turn sixteen. You studied your entire life since your eleventh at Ilvermorny, the US wizard school, but for some reason, your parents changed you to Hogwarts.
Professor McGonagall had just caught you at Hogsmeade station, and now you're against the wall, besides the door of her office. She told you to wait until she call you to get in.
Suddenly, some voices fill the corridor softly. They were people approaching. Not so far away, you saw a trio. A ginger tall boy in the middle, on his left side, a boy with black messed hair and glasses, and the only girl, with bulky hair, with a clever aspect.

They're all independent and don't have scared of getting into trouble (Hermione, just a little). Harry and Ron love quidditch, and play chess. Hermione doesn't know how to play and doesn't like to chess, even she's so clever.
