Item #: SCP-191
Object Class: Euclid
Special Containment Procedures: SCP-191 must be contained in a sealed steel chamber completely devoid of visible light. The walls and ceiling must be suitably braced to withstand regular high-energy impacts. Secondary containment in the form of a completely opaque light-proof "tent" is to surround the chamber at all times. Access by cleared personnel is limited to bi-weekly feedings, and must be via a two-stage airlock, preventing outside light from entering the chamber. Surveillance by infra-red cameras and MR-imaging must be maintained at all times, and any movements or other activity by SCP-191 must be reported to the on-duty Level 3 supervisor.
Description: SCP-191 is a quadrupedal insect-like creature 1.52 m (5 ft) long and 0.91 m (3 ft) tall, with a chitinous exoskeleton composed of iron sulfides, similar to the shells of arthropods living near deep-sea geothermal vents. It has four free-moving appendages similar to dragonfly wings, but has exhibited no ability to fly under its own power. SCP-191's wing-appendages absorb light in the visible spectrum, and convert it into physical force. The conversion occurs instantaneously, at the rate of approximately 10,000 joules for every 1.5 candela. The energy is emitted from SCP-191's body equally in all directions. SCP-191 is carnivorous, but also seems to draw nourishment from exposure to light. Feedings consist of 570g (20oz) of raw beef, and a time-delayed flash bulb set to emit a single 1-candela pulse.
Addendum: SCP-191 was delivered in a black canvas bag to Site-26 in Stockholm in early 2008. Sender unknown. Opening the bag in standard clinical lighting conditions led to Incident #26-0734-08. SCP-191 is currently contained at Site-32 at the North Pole.
