The virridroni (/ˈvɪrɪdroʊni/) is a slender, white stranger with black hands and feet, very pale stripes, and a black tail-tip. Half of all individuals present with a black snout tip, giving its markings an enclosed symmetry. Its surface is soft and smooth, and feels more like silicon than human skin, while its onyx-colored inner flesh is sinewy. Its teeth, gums, and tongue are pure white, and it exudes a thick white saliva from all soft tissues within its mouth. Its slick-walled mouth does not connect with its body cavity, which is filled with slippery grey intestines. It walks with an arched back, its head always held parallel to the ground. The position of the virridroni's tail varies between individuals, but remains constant throughout its life. The virridroni exudes no odors from its form. Under darkness, its body gives off a pale glow.
It displays marked vulnerability to its surroundings, with extremes of both heat and cold causing its body to soften, dissolve, and disappear. Even slight wounds tend to provoke a similar response, with the virridroni's skin liquifying around the point of injury.
The virridroni does not speak, but certain individuals do emit a soothing tone, similar to a sine wave, during rare and serene occasions1.
The virridroni appears in a wide range of locations, with a marked tendency towards interior locales. During daytime, it generates most specifically around open windows, white-painted bricks, and quiet overgrowth, while during nighttime, it tends to generate in pitch-black rooms, residential areas, and indoor gardens.
The virridroni first appears in a minuscule, rounded form, which elongates and expands in height and width until reaching full size over a period of around two seconds. This expansion is not accompanied by any sound, although the virridroni's growth does create a faint but not unpleasant sweet smell in certain instances, in addition to a slight decrease in temperature. Groups tend to appear in sequence and in clusters, like raindrops on the surface of a pool.
The virridroni possesses a demure and sensitive disposition. It moves through its environment with discreet steps, observing all, but affecting little. It walks with a distinctive back-and-forth sway, like a chameleon imitating the shaking of a wind-blown leaf, although it is not unsteady, nor is it graceless in these motions. It twitches its tail tip in response to loud sounds, but displays no disquietude, otherwise.
The virridroni is primarily a wanderer, and engages in limited actions. It takes in its surroundings with a calm detachment, its face belying no emotion. It travels in long, non-looping paths throughout its environment, and, upon reaching a dead end, moves in a circular pattern and exits the area in the same direction from which it came. Groups of virridroni sometimes gather and move together, but do not react to one another, and disperse after several miles of travel.
The virridroni's presence causes white objects and surfaces to glow with a soft, tranquil light. This effect is limited only to pure white objects, with very light grey objects glowing only vaguely, and anything even slightly darker casting no glow at all. This effect is most noticeable in dark rooms, and affects all objects within a radius of 2.5 bodily lengths, with objects closest to the virridroni casting a brighter glow.
When encounters with sensitives occur, the virridroni retains its guileless disposition. It does display some curiosity, and circles sensitives, or taps the ground around them, but it does not tend to approach too closely, although it lacks the fearfulness of some of its more shy brethren. The virridroni's white-illuminating effect does not affect human beings, and as such, the teeth, hair, and eyes of sensitives remain un-illuminated.
Despite its peaceful and pleasant effects, the virridroni is unable to survive the presence of sensitives.
As it dies, the virridroni produces a quantity of fluid equivalent to 5.4 times its bodily mass. This effect always occurs after exactly 116 second of proximity to a sensitive. Attacking the virridroni before this time has elapsed triggers the same response. The virridroni does not retaliate when injured, nor does it display any apparent ill-will towards its assailant.
At the end of the virridroni's life, its body grows transparent, though its movement does not cease, and it continues to travel into invisibility, leaving behind no body behind and nothing to mourn.
