You were lost in the forest, you ran without looking, it was night, suddenly you stepped on a branch and slipped in the mud and fell, you tried to stand up but suddenly the ground you fell on became a hole and you fell into it, you fell and landing on one of the fireplaces at Hogwarts and to be precise in the Gryffindor dormitory, Harry, Hermione and Ron were shocked to see you fall from the top of the fireplace.

Hermione: Who are you?! Ron : Bloody Hell?! Harry : Calm down guys!
