Shadow Witness

Humanoid entity whose body is composed entirely of accumulated shadow. Any extended exposure to light dissolves its surrounding shadows into a featureless mass. Subject only moves when light sources are unstable.

Travels along ceilings and corners. Hunts in flicker. Absorbs the surface area of any unattended shadow until the source object becomes featureless.

Containment chamber maintained at constant 4500 lumens. Three redundant lighting circuits. No backup will be reduced without dual approval.
