Fiction:Pareidolia/Subject 10

Subject: Subject 10, nicknamed Shade by personnel

Class: 4 - '''Major precautions should be taken to avoid direct contact with this individual. Exclusive authorization only.'''

Containment Procedure
Subject 10 must be kept in a 5m x 5m x 5m chamber at all times. No light is to be allowed into the room as Subject 10 reacts to light with extreme hostility. Exclusive personnel are only to communicate with Subject 10. The chamber door, under no circumstances will be opened. All personnel are required to wear black clothing when entering Subject 10's chamber. No openings whatsoever are allowed in this chamber.

Description
Subject 10 is an intangible being that can be described as a living shadow, hence the personnel nickname 'Shade'. Subject 10's chamber is consistently kept in darkness, taking light as a target. Therefore it is safe to assume that Subject 10 relies on sight to catch prey. Previous attempts to communicate with Subject 10 with a light source present has meant the assumed death of personnel - bodies have not been recovered or even detected.

Containment breaches from Subject 10 have proven to be difficult to quell. Subject 10 is indistinguishable from shadows. Authorities have required the assistance of Subject 7 to retain Subject 10 through unexplained method. In the presence of light, Subject 10 is extremely hostile and will terminate anything it can see. It is docile in the absence of light, which authorities have assumed that Subject 10 can only see.

Subject 10 in its containment breach has been shown to use the shadows of personnel to hide. Some images have been taken of Subject 10's appearance in presence of light, and looks strikingly similar to that of Subject 7. Attempts to recognize Subject 10's identity through Subject 7's addendum has so far failed.
