Kerhoa

Kerhoa is a fictional mineral frequently used in speculative fiction and worldbuilding. Descriptions vary, but it is typically portrayed as a translucent crystalline substance with a blue to violet hue that forms under extreme metamorphic or mantle-like conditions. The term appears in multiple independent works, and there is no single canonical definition.

Physical properties commonly attributed to kerhoa include monoclinic crystal symmetry, a vitreous to pearly luster, Mohs hardness around 6–7, and a relatively high refractive index. Color ranges from azure to lavender, and in some depictions kerhoa exhibits noticeable pleochroism or an internal glow when exposed to ultraviolet light.

Formation and occurrence: In most portrayals, kerhoa crystallizes from silica- and metal-rich fluids during subduction, high-temperature metamorphism, or deep mantle exhumation. It is usually described as rare, localized to specific rock types such as ultramafic hosts, and often found as prismatic or tabular crystals in metamorphic veins.

Uses and cultural significance: Within fictional settings, kerhoa is valued for properties such as high thermal stability, potential energy storage capabilities, and light-emitting or optical features. It is employed in advanced ceramics, jewelry, or as a power source in speculative technologies. Some narratives tie kerhoa to ancient civilizations or cosmic phenomena.

Real-world status: Kerhoa is not recognized as a mineral by real-world geology or mineralogical authorities. The concept exists only in fictional contexts and is used for worldbuilding, storytelling, and speculative design.
