fogait

Fogait is a term used in speculative fiction and tabletop role-playing games to denote a fictional substance or energy with properties that vary by setting. In most portrayals, fogait is not a real material, but a plot device that enables unusual science or magic. Writers often describe it as translucent or luminescent, and as something that can be volatile, absorbent, or highly energy-dense.

Because fogait is defined by the needs of a particular story, its characteristics are highly variable. It may be a mineral or a gas, a condensed form of ambient energy, or an aura that interacts with runes, devices, or biological systems. Its stability, reactivity, and methods of extraction or synthesis are typically invented to suit world-building requirements.

Common uses in fiction and games include powering advanced technologies, enabling faster-than-light travel, acting as a catalyst for magical effects, or serving as a scarce resource that drives political or economic conflict. In role-playing settings, fogait is sometimes a collectible resource with tiered scarcity and specific in-game effects, such as improving equipment or unlocking special abilities.

Etymology of fogait is uncertain and varies by author. The name is generally treated as a fictional noun rather than a term with real-world origins. As a flexible device, fogait invites creative interpretation while remaining a neutral label for an enigmatic substance within a given universe.
