The jueroudrine (/dʒəˈɛəɹəʊdɹɪnzi/) is a long, limbless stranger with thick, ruddy skin. Its eye markings are either light-and-red, or entirely red, with tear markings that are either one unbroken marking, or contain a single non-contiguous teardrop marking. Its inner flesh is solid and rubbery, and is either silver or bright red in coloration. Its throat extends down the entirety of its body, and its digestion is rapid and exudes itself in smell rather than any kind of offshoot. The jueroudrine appears only as a pair of individuals, which express complimentary variation.
Though lacking in regenerative ability, the jueroudrine's skin resists almost all cutting or puncturing, and is unaffected by extremes of temperature. Despite this durable exterior, its insides are soft, and begin to rot immediately upon exposure to air.
The jueroudrine does not speak, communicating instead through a low-frequency churning noise that emanates from within its serpentine body. This sound, while audible in volume, is felt more than it is heard, although these vibrations cause no disturbances to its surroundings.
The jueroudrine generates in tin-walled, subterranean cylindrical rooms with no less than two doorless entrances, and no more than four. Dirt floors seem to be preferred, with height playing no factor whatsoever. The chamber's diameter is always at least 27 feet in length, but no larger than twice this distance. The likelihood of a jueroudrine infestation is further increased in the presence of rotted wood, rusted metal, piles of dissimilar objects, and a cool dampness in the air.
Within these spaces, the jueroudrine appears as a pair of small, worm-like individuals, which grow to full size over the span of two to seventeen months.
The jueroudrine possesses a patiently edacious disposition. Its main directive is to eat objects within its environment, consuming a new object every few weeks. It never leaves its territory, and when not eating, weaves in circles and loops, idle but not still.
Though initially random, its tastes grow more similar to its own appearance, with this similarity usually focused on a single criteria. One jueroudrine may seek out more and more tubular objects, while another jueroudrine may gravitate towards objects that match its coloration.
Eventually, the jueroudrine tuns its attention on its companion, biting onto the end of its tail and working its way upward. It displays no aggression in doing so, with this latching-on behaviour causing its companion to latch on to it, as well. In response to being consumed, the jueroudrine lengthens its body, thus keeping the size of the loop constant. All jueroudrine pairs begin to consume each other by the halfway point in their lives, and once a pair of jueroudrine latches onto one another, they engage in no further actions.
A jueroudrine takes interest in a sensitive only if the sensitive's appearance makes them the most jueroudrine-like object within an environment, or if the jueroudrine's territory is otherwise object-less. A jueroudrine that seeks out strain-similar objects by color, for example, may find a sensitive more appealing than a neon-colored object; a jueroudrine that seeks out strain-similar objects by size may approach a sensitive if they are the closest-sized object in a room to themselves.
While a pair of looping jueroudrine displays no interest in the sensitive, they do grow more ravenous in their biting of one another.
The jueroudrine's presence elicits a compulsive urge to bite at the skin and consume the body in small amounts, particularly on the hands and forearms. This urge disappears once the affected sensitive has consumed 1-5% of their overall body mass, or after twenty-seven years following an encounter.
As the pair of jueroudrine ages, each individual loses their ability to constantly grow, and the loop gets smaller and smaller. Unable to eat each other entirely, they eventually bite through their companion's skin, each decapitating the other. Their corpses turning foul-smelling and congealing as they rot, separate once more.
