- Physiological Summary
- Fleech Swarm is a mass of tiny parasitic leech-like organisms that turn humid air and stagnant water into a feeding hazard.
Overview
Fleech Swarm is a collective record for tiny parasitic organisms that feed through mass attachment. A single individual is minor, but thousands together can drain, irritate, and panic larger hosts.
The swarm occupies the border between water and air. The subject is most dangerous where humidity, blood scent, and stagnant water overlap.
This makes the subject useful for tracking how parasites move through wet rooms as a living cloud, especially when the surrounding conditions are recorded with the body.
Anatomy And Physiology
The body is organized around soft attachment bodies, hooked mouthparts, and swarm-level chemical following. These structures let Fleech Swarm survive pressure from dry air, host defenses, and larger wetland predators.
Each Fleech feeds through small punctures or softened tissue contact. Support needs include blood, exposed fluids, decaying tissue moisture, microbial films, and mineral-rich stagnant water.
Threat response centers on swarm attachment, blood drain, irritation cloud, wound-seeking movement, and retreat into humid darkness. Each response follows from the body's relationship with nearby surfaces, cover, or prey.
Habitat And Range
Fleech Swarm is associated with bog air, flooded tunnels, humid vents, stagnant pools, and carcass-rich marsh pockets. Suitable sites must provide moisture, host traffic, and sheltered brood water.
Field signs include speckled bite clusters, dark water films, gelatinous brood strings, and ripples moving against current. These traces usually identify a living range before the subject is seen directly.
The range is patchy where humidity changes or wounded hosts pull the swarm out of its usual pocket. Nearby chambers may look similar while lacking the one condition the subject requires.
Behavior And Ecology
Fleech Swarm usually follows chemical gradients from blood, decay, and warm respiration. The signs often appear before direct contact.
Disturbance causes dispersal into mist, water, or crevice cover. Neighboring fauna respond by changing routes, timing, or shelter choice.
Ecologically, the swarm recycles fluids from carcasses and marks weak prey for larger predators. Its presence therefore alters more than the immediate point of contact.
Reproduction And Development
Egg strings or gelatinous brood masses develop in stagnant water before emerging as free-swimming or airborne juveniles. Early development is tied to the same conditions that support the adult range.
Young likely begin as free-swimming forms before developing stronger attachment tissues. That juvenile phase is usually the most vulnerable part of the life cycle.
A complete survey should preserve brood gel, water chemistry, host bite patterns, and swarm density across humidity changes. Those details distinguish a breeding site from temporary passage.
