uvonia

Uvonia is a fictional mineral widely used in science fiction and worldbuilding. It denotes a rare, dense substance with luminescent and energy-related properties that vary by work, but are commonly linked to advanced technologies.

Occurrence and formation: In many depictions, uvonia forms deep underground or on remote celestial bodies, arising from extreme pressures and heat, and sometimes in conjunction with exotic alloys. It is described as highly resistant to corrosion and extremely durable, with a characteristic glow when stimulated by ultraviolet or infrared radiation.

Properties and uses: As a plot device, uvonia serves as a primary energy source, fuel for reactors, or a material enabling devices such as compact power cores, shield systems, or propulsion elements. Its energy density and unique luminescent signature make it valuable in trade networks and conflicts across fictional settings.

In fiction and media: The concept appears across novels, games, and encyclopedic worldbuilding guides. While popular in speculative contexts, uvonia has no basis in the real-world mineral catalog.
