A 2.5K HMI supplies the beefy backlight here, while a blue-gelled redhead out of the top right of frame is aimed down the steps to pick out Athos (Edward Mitchell). An orange-gelled Dedo creates a pool of light around the candle, and everything else is natural bounce off the surrounding stonework. A second blue-gelled redhead at the foot of the stairs firing across the stonework would have made all the difference to the believability of the environment, but hindsight is 20/20.
