Hand-held flames

"Professor Lupin appeared to have woken up at last. Harry could hear movements in his corner. None of them spoke. There was a soft, crackling noise, and a shivering light filled the compartment. Professor Lupin appeared to be holding a handful of flames. They illuminated his tired, gray face, but his eyes looked alert and wary."
