A while passed without any sign of them, and Hermione knew this as she kept track of time by counting out the seconds in each minute that passed. Eventually she got cold enough that she got up and went to collect some broken tree branches, arranging them in a neat little pile on the ground, where she then started a fire with her signature bluebell flames. Not only would it keep her warm, but it would serve as a beacon to let her friends know she was there.
