Chalk Creatures are a class of entities composed entirely of Chalk.

Morphology

Chalk Creatures possess a vaguely humanoid morphology, though their proportions are frequently distorted or malformed. Their exterior resembles bleached coral in both texture and appearance, exhibiting a brittle and porous structure. The head is largely featureless, lacking identifiable sensory organs such as eyes or a nose. The only consistent facial structure is a large, toothless mouth. No conventional internal anatomy has been observed.

As their designation suggests, Chalk Creatures are composed entirely of Chalk. The mechanisms governing their formation and animation are unknown. They are most commonly observed forming spontaneously in regions containing substantial Chalk deposits. The entities display significant structural fragility. A sufficiently forceful impact, particularly directed at the torso, is typically capable of disrupting cohesion and reducing the organism back to an inert dust state. Chalk Creatures are aggressive toward nearby organisms.

Environmental Dependency

Chalk Creatures rely heavily on the presence of Chalk within their environment for both perception and movement. Evidence indicates that they are capable of detecting activity within Chalk-rich areas, regardless of whether the Chalk is grounded or airborne as particulate matter.

Locomotion is similarly dependent on Chalk distribution. The entities appear to utilise Chalk as interconnected nodes for traversal, allowing movement only through areas where sufficient quantities are present. Locations containing little or no Chalk are effectively inaccessible to them.

When placed in environments devoid of accessible Chalk ,Chalk Creatures enter a vegetative or inert state. In this condition, they become entirely incapable of movement or environmental response.
