The source of the disgusting smell and the faintly bluish haze hovered in the air above the unconscious guards. It looked like a man-shape made up of thicker areas of mist swirling and shifting in the depths of the haze as it hovered there. The air elemental was able to penetrate any physical protection with its insubstantial body, using its power to control its native element to choke the guards with noxious air. As Hammer watched in fascination, the spirit seemed to collapse in on itself and all of the mist in the room was drawn to a single point in the air like a whirlpool of air. When the room was clear, the misty spirit was also drawn through the invisible hole in the air and vanished in a glimmer of light.
