 Item number SCP-17 Object Class Keter Special Containment Procedures SCP-17 is contained in an acrylic glass cage 100 cm x 50 cm x 50 cm centrally suspended in a concrete room measuring 6 m x 6 m x 4 m. Attached to the walls, ceiling, and floor of the room, our high-intensity arc lamp spotlights pointed directly at the acrylic cage to ensure that SCP-17 is constantly exposed to light from every angle. Personnel assigned to the SCP-17 control room are to monitor the functionality of the spotlights and the emergency generator system and call for maintenance immediately upon knowledge of a burnt out lamp or an issue with the generator. The only circumstance under which personnel are allowed entrances to replace lamps. Personnel entering the room are required to wear the designated full-body reflective suits and must be cautioned not to step in front of functional spotlights. Description SCP-17 is a humanoid figure approximately 80 cm in height and atomically similar to a small child, but with no discernible identifying features. SCP-17 seems to be composed of a shadowy smoke-like shroud. No attempt to find any object beneath the shroud has been successful, but the possibility has not been ruled out. SCP-17's reaction to shadows cast upon it is immediate and swift. SCP-17 leaps at the object casting the shadow and completely encloses it in its shroud, where upon it returns to its normal size, leaving no trace of the object behind. Lesson complete.
