gazlarn

Gazlarn is a fictional mineral term used in worldbuilding, science fiction, and fantasy fiction. It is described as a rare translucent mineral with a pale blue-green hue that glows faintly after exposure to light.

In most settings gazlarn forms in hydrothermal veins within volcanic rocks, often alongside quartz and mica. Crystals are typically tabular to prismatic and range from millimeters to centimeters. The color and glow are usually attributed to trace impurities such as iron, manganese, or copper, and to defects in the crystal lattice that influence light absorption and emission. Reported hardness is moderate (about Mohs 6–7), and the material is described as relatively brittle, which affects how it is mined and handled in narratives.

Common narrative uses include aesthetic value in jewelry and speculative energy properties, sometimes described as storing or releasing light or kinetic energy. Gazlarn is also employed as a plot device to motivate mining expeditions, trade dynamics, or political conflict over a scarce resource. Etymology links gazlarn to a fictional Qarathi word meaning twilight stone, with regional variants and local legends varying across settings.

Note: Gazlarn is not a real mineral recognized by actual geology. It exists as a construct for fictional worlds and appears in various roleplaying game materials, novels, and worldbuilding resources as a versatile elemental concept.
