Electricity

A young man in a dark robe stands in a dimly lit, red-walled corridor, holding a lightsaber. He turns and faces an older man with pale skin, who is lying on the floor and screaming as bright blue lightning arcs from the lightsaber into his body. The older man's face contorts in pain as the lightning courses through him, and the young man maintains his stance, holding the weapon. The scene repeats in a loop.
