Kootmist

Kootmist is a term used in speculative fiction and tabletop gaming to describe a luminous, fog-like phenomenon that appears in certain fictional worlds. It is not a real meteorological term and has no basis in established science.

Etymology and origin: The word combines the fictional planet or locale name Koot with mist. The concept arose in online fan communities and role-playing game circles as a mood-setting element and plot device.

Description and properties: Kootmist is described as a pale blue-green, self-luminous fog that drifts over landscapes and interacts with surface moisture; it can refract light to create halos; in some narratives it reveals hidden structures or pathways while muffling sound and reducing visibility.

In usage: In fictional worlds, kootmist often signals distance from civilization, or acts as an environmental hazard; in tabletop games, it can function as a mechanic that reduces line of sight or dampens magic. It can also serve as atmosphere, signaling ancient technology or lost civilizations.

Cultural role and variants: Kootmist appears across multiple works and game settings, with variations in intensity, duration, and effects on perception. Some creators treat it as a benign, almost navigational aid, while others cast it as a dangerous veil that hides threats or treasures. Discussions around consistency and world-building etiquette often address how to integrate its luminescence, physics, and lore without breaking internal rules.
