Hp travel

so it's basically by the time turner, I'll explain... basically you decided to visit England yes you are a muggle in 2025 you find a small locket on the roads of the muggle town, you pick it up and turn it slightly and then you see fandom things you are now in 2011 the year of the wizarding battle against Lord Voldemort and his army so you decided to walk around but you see some people you find a few engines and then the group of people including that 18 year old so looking students one of them wore black glasses, had short black hair, pale skin, emerald green eyes and a weird lightning bolt shaped scar on his forehead..what will you do? investigate or wait till this time turner gets you back to 2025?
