vajauk

Vajauk is a fictional mineral used in speculative fiction and worldbuilding. It has no real-world existence outside of the works in which it appears, and there is no single canonical definition; instead its properties vary by author. In many projects, vajauk is treated as a rare crystalline substance prized for its beauty and potential energetic properties.

In most portrayals vajauk is a translucent mineral with pale violet to blue coloration and a vitreous luster. It often exhibits phosphorescence in darkness, emitting a soft glow due to trace elements. Reported hardness ranges from 6 to 7 on the Mohs scale, and its density is variable across depictions. Its composition is described as a complex silicate-oxide with impurities of rare earth elements and transition metals.

Vajauk is depicted as forming under high-temperature, high-pressure conditions, such as subduction-zone analogs or deep crustal metamorphism. Some authors describe laboratory synthesis enabling wider use, influencing supply and regulation within the story world.

In fiction vajauk is used as a component in energy resonators, quantum storage devices, or as ornamental gemstones in ceremonial objects. Because of its scarcity and perceived properties, vajauk often features in plots about mining rights, trade routes, and environmental concerns, with governance varying by fictional setting.

The name vajauk appears in multiple languages within the fictional universe, often interpreted as "light-stone" or "memory crystal." It has become a common trope in worldbuilding circles as a versatile element around which economies and cultures can swirl.
