The Hidden Root[]
Entity 42[]

Beware the lines where darkness flows.
Do not touch what creeps along,
Its bite is quick, its anger is strong.
Don't approach, and stay back;
For threads that move may deliver you pain.
Description[]
The Thread-Bug is a beetle-like predatory insect covered in a dense layer of hard scales, which gives it the ability to withstand considerable physical impact. It features a pair of thin, and translucent wings that enable only a brief flight. These wings are primarily used for short-distance glide between cables or strands rather than sustained movement.
Its head features two long, and flexible eye stalks that extend from its skull like cords. Its main tools are its strong canines. They are sharp, and metallic-like teeth evolved to cut through ropes, wires, and fibrous materials. Each of the Thread-Bug’s limbs have fur, which resembles frayed strands of a rope. This appearance supports its disguise of hanging wires and strands, which makes it hard to be spotted from a cluster of damaged or hanging electrical cords in dimly illuminated areas.
This entity are separated into two sexes. Males are larger with broader bodies, and thicker, and more scales that give them a bulkier appearance. Their eye stalks are slightly shorter and sturdier. Females are smaller and more slender, with visibly longer and denser fur covering their limbs.
Behaviours[]
Thread-Bugs are territorial and highly aggressive creatures that prefer to hide themselves within tangles of ropes, wires, and strands. They use these areas as camouflage and hunting zones, and stay static and motionless for long period of time until movement nearby triggers their predatory instincts. Despite their small size, they show unexpected intelligence and coordination when stalking or capturing prey.
They are hostile toward almost all forms of life, and sometimes include their own kind. Encounters between Thread-Bugs typically result in violent clashes, usually over territory or competing for a female. Such fights are short but intense, with one retreating after sustaining damage to its limbs or scales.
When attacking, the entity uses three methods. The first and most common involves waiting for prey to come within close range, then quickly leaping forward to inject venom through its canines. The second involves a short flight, and uses its hard scales as impact armor to ram into the target. The third method is more complex: the Thread-Bug uses nearby ropes or wires, and wraps them around its prey to restrict movement before delivering a bite.
In environments without suitable materials like wires or strands, the entity adapts by hiding in dusty corners, within machinery, or in narrow spaces where its dark coloration supports it to blend in. On rare cases, Thread-Bugs have been observed attaching themselves to larger entities, and live parasitically by cutting into their outer layers and drawing in minimal sustenance while they try to stay partially hidden.
Reproduction & Growth[]
Thread-Bugs reproduce by laying small, and oval eggs within thick clumps of ropes or wires. Each clutch contains up to twenty eggs, with a sticky film that keeps them secured and attached. The eggs hatch after about six or seven days, which depends on temperature and humidity in the environment.
The larvae, known as threadlings, hardly resemble its adult form, its skin is soft, and pale as they have not developed scales yet. They feed on dust, fibers, and small organic fragments. They grow quickly, and moult several times as their scales harden and limbs strengthen. Within a month, they become juveniles with weak venom and short flight ability.
By around 6-7 months, Thread-Bugs reach full maturity, and gain their tough scales, long eye stalks, and sharp canines. Adults live and hunt alone, and show no care for their offspring. Many larvae do not survive, but those that do become highly resilient predators.
Habitat[]
Thread-Bugs reside in dark, and narrow areas with ropes, wires, or tangled materials. They are commonly found in maintenance shafts, storage rooms, and abandoned industrial spaces where light is scarce. In places without ropes or cables, it may hide in dusty corners, wall cracks, or inside machinery. They are usually seen in Level 1, Level 2, Level 3, Level 5.3, Level 8, etc.
Discovery[]
The Thread-Bug was first documented after a series of electrical failures in a maintenance sector of a group outpost on Level 2. Initial reports blamed the environment, but further checking showed clean bite marks on the wires. During one investigation, a small, and beetle-like creature was found climbing to a damaged cable, and attacked the inspection tool with unexpected aggression.
The specimen was captured and placed in containment, and its cutting ability and venomous bite were soon noted. From this discovery, similar entities were found across several dim, and wire-filled areas, which confirmed that the damage had been caused by a new widespread species rather than a single organism. This led to its official classification as “Thread-Bug.”
