The lendrimiere /lɛndɹɪ'mɪɹ/ is a crawling stranger with numerous small, short arms, and a fatty body that drags behind it when it moves. Its skin is thin and rubbery, while its dark and appreciably translucent inner flesh resembles a tough jelly; contact with this meaty gel causes vomiting, shaking, and blurred vision. The clear-to-blue-tinted mucosal fluid that the lendrimiere exudes from its underside is initially thin, but has a tendency to grow gummy and stringy if touched. The lendrimiere's eyes shine outwards with the focus and luminosity of a pair of automobile headlights, with some flickering occurring in blink-like sequences as the lendrimiere ages.

Though hardy and regenerating from most non-fatal injuries within a week, the strain is vulnerable to changes in its environment, and requires damp surroundings in order to sustain its slickness, its skin detaching when conditions become too arid. Freezing temperatures cause the lendrimiere's body to dry out, whereas temperatures of above 90°F cause it to soften and sag, with anything above 111°F congealing and dissolving it completely.

Its voice sounds like a muted hum.

The lendrimiere appears in or around abandoned or unused train and subway tunnels, and only in areas far from stations or pedestrian walkways. It vastly prefers earthy, dim environments, with more well-lit or modernized tunnels being less likely to host a lendrimiere infestation. Within these spaces, the lendrimiere starts off as a rounded globule of translucent jelly, which grows over several months. The lendrimiere's shape becomes apparent only at the end of this process, at which point the outer surface thickens to form the stranger's skin.

The lendrimiere's demeanor remains perpetually stupefied, its reactions delayed and all emotive abilities dampened. It crawls from place to place with a weary dragging, its surroundings becoming slippery with the fluid that the lendrimiere leaves behind; this fluid may evaporate completely within several days. The lendrimiere does not tend to be very talkative, communicating only in brief reaction to unexpected stimulus.

The lendrimiere displays an interest in graffiti, which it approaches and remains focused on, its hands sliding across any images along ground level, and the lendrimiere attempting to climb upwards towards out-of-reach designs. More complex designs garner more interest, while simple lines or letters are dismissed after a lackluster stroke of the hand. Grouping also occurs around more complex images, with small clusters of lendrimiere tending to remain in the vicinity even once direct interest has faded.

The lendrimiere requires some outside sustenance, and seeks out spilled oil or other fluid chemicals, which it absorbs directly through its skin. These feedings are infrequent, with most lendrimiere needing to consume fluids less than ten times over the span of their lives. Nonetheless, lendrimiere are competitive towards this source of energy, with fights occurring over any fluids discovered. Aside from this emulous behaviour, and a vague tendency to group together, the lendrimiere is not directly social, with interactions being limited to momentary touching of the hands, and only in cramped environments.

Late at night, the lendrimiere whistles.

Under normal circumstances, the lendrimiere is indifferent to sensitives. Although some individuals are more shy, and others more egregious, it does not seek out direct interaction, nor does it display fear or direct avoidance unless attacked, at which point it attempts to seek out shelter, curling up in defeat when unable to retreat to safety.

The lendrimiere does, however, display great interest in sleeping sensitives, which it first approaches, and then courts by bringing them small objects such as stones, bottles, or pieces of wood, which it places around the sensitive's body in clumsy, but not entirely random formation. The lendrimiere is able to tell the difference between a sleeping sensitive and a sensitive who is only pretending to be asleep, and has no interest in corpses.

Upon the sensitive's awakening, the lendrimiere's disposition dulls once more, complex behaviours remaining unobserved.

Its effect on sensitives is similarly muted, but non-negligible, with proximity to the lendrimiere causing a mental blankness comparable to either sedation or meditation, and with no physical side-effects or lethargy.

As the lendrimiere ages, its skin becomes rougher and expressed fluid less readily, leading to numerous scrapes and other contusions to the lendrimiere's underside. The lendrimiere does appear pained by its toiling drag, and grows more sluggish in return, eventually refusing to move any further, even when presented with normally attractive stimulus. It dies with a silent slump, its skin softening and sloughing off, and its jelly-like interior drying up and crumbling apart. The small chunks of dried flesh left behind become plasticine, resisting decomposition or dissolution, and taking many thousands of years to break apart on their own. Other lendrimiere display laconic interest in these pieces, running their palms across the chunks, but abandon them after several minutes to resume their listless lives.
