SCP-266 Will o' the Wisp

SCP-266 is a number of free-floating masses of gaseous material, possessing a natural luminescence which exists as a bright purple or red glow. In most cases, SCP-266 feels cold to the touch, and exerts an endothermic effect on its immediate surroundings. Despite having no obvious nervous system, SCP-266 appears to react to stimuli and has been observed to learn certain habits based upon its experiences.
