CCC-59

Containment
CCC-59 are to be kept in a hermetically sealed containment cell. Any way for them to leave (under doors) are to be sealed. Cameras should be used to observe the instances in their cell, not glass. Lights are to be projected towards the back wall, so that the instances stay clearly visible. In a breach, all lighting in the area is to be cut, until they can be recontained again.

Description
CCC-59 are predators. They exist purely as shadows, only able to sense and interact with other shadows. Apparently injuries inflicted on the shadows of things will appear on the thing projecting the shadow. These predators can slip under doors and through glass. They are unable to hunt at night, due to the shadows being hidden by the darkness. According to their shadow, CCC-59 instances are about 1m tall, and 2m long. They have needle like teeth, and no eyes. CCC-59 are extremely hostile, and hunt in groups of 2, killing medium sized animals and humans. When their shadow is gone, they will "die".
