The finidreni (/ˈfɪnɪdɹɛni/) is a stranger no larger than an adult human hand, with four small and rounded tendrils, two longer, red-hand-tipped appendages, and a smiling, toothless mouth. Its flesh is light in color and exceptionally greasy when exposed to air, but maintains an almost sponge-like composition when within the confines of the finidreni's smooth and soft skin. It possesses only a single structure of coiled or spiraling intestinal tubing within its body, which starts at a point just between the eyes and continues to past its midsection; hollow and pristine, these organs, like its flesh, lack odor altogether.
The finidreni's voice is high-pitched and childlike, and it speaks through a simple language formed through experimentation and repetition, the phonetic palette varying between individuals. Still, speech tends to be restricted to moments of particularly exquisite happiness, with squeals and giggles accounting for the majority of the finidreni's frequent expulsions.
The finidreni is most prevalent in hot or arid climates, finding a home within high-ceilinged rooms, near undecorated walls, or beneath rarely-touched ceilings held high with long columns.
The finidreni starts off very small, and travels in loops during this formative stage (during which it lacks any characteristic effects). It takes only a few hours to reach full size, and which point it becomes fully erratic in its wandering.
Just slower than a songbird and far more haphazard, the puckish finidreni moves with a flickering playfulness, its explorations fanciful but rapid, with this stranger never staying in the same location for anything more than a brief and infrequent circumlocution.
A finidreni's range can cover hundreds of square miles, if not more, and its paths can reach up to thirty miles per day.
It does not interact with objects aside from poles or tubular shapes, which it circles or passes through in a dizzying series of spins, its interest held by everything and nothing all at once.
The finidreni's presence causes a sense of intense joy and euphoria. While near the finidreni, a sensitive's problems seem not to matter, all pain seems bearable, and every detail in the world causes a sense of either deep reverence or delight.
Despite this exceptionally beneficial effect, the finidreni itself displays no interest in sensitives except to avoid them. It moves too quickly to be caught or even pursued, and, despite its lackadaisical nature, remains shrewd in the face of traps, dead-ends, nets, or weapons, never approaching these objects by more than fifty feet.
Upon encountering a sensitive, the finidreni does not return to the location in which the encounter took place.
It flickered through the window and forever gone, it did remain. She died penniless; a martyr to a cause unseen, and so her body became rolled in carpet and dumped out into the harbor, victim'd by those who knew little of her plight." Marion F. Gentry. I Walked with Armitage, 978
Although the finidreni tends to manifest only sparsely, thus making interactions exceptionally unlikely, encounters between individuals are only improbable.
When two finidreni meet, the stability of each drops to negligible levels.
They were still there, of course, not one inch to the right or the left or up or down. But now they had a sickening kind of rot around their eyes; and there was no hint of any good-rush in my stomach, though I will clarify that the coldness in my gut was not forced there by them, but rather stirred out from whatever bad thoughts I was still carrying from (the events between).
So caught up in this brief recollection that I did not pay any mind to how that rot did keep on spreading out. And I reached my hand out, and they became as rags that fell to dust and nothing hit the ground." Tages, S. Washington at its Knees (The Rickswing), line 2-14
The finidreni exhibits no signs of aging, and dies instead with a sudden softening of form, its slack body drifting downward like a fallen leaf. There, its corpse persists, retaining some warmth in its features, but disintegrating to impossibly-fine powder upon being touched by a sensitive, unmourned by both members of its own kind and those whom it seems placed here to exalt.
