Hetimeve

Hetimeve is a fictional mineral used in educational and literary contexts to illustrate how minerals might be described in a neutral, encyclopedia-style entry. In the standard fictional narrative, it forms in high-temperature, low-oxygen hydrothermal veins and crystallizes in the monoclinic system, typically appearing as short prismatic crystals.

The name hetimeve is a constructed term, combining elements intended to evoke heat-related formation and a regional source associated with the fictional type locality. In these treatments, a provisional chemical composition is provided mainly for instructional purposes, rather than to assert a real-world formula.

In physical terms within the fictional canon, hetimeve is described as a complex silicate containing iron, vanadium, titanium, and silicon in a silicate framework. It is often depicted with an olive-bronze color and a metallic to submetallic luster. The hardness is given around 6 on the Mohs scale, with a density near 4.7–5.0 g/cm3. Some descriptions note mild pleochroism and occasional weak fluorescence under ultraviolet light.

Occurrence and discovery in the fictional literature place the type specimen in hydrothermal veins of the Wyrnstone Belt. The first publication is typically dated to the late 1990s in a supplementary mineralogy text, and fictional authorities in the narrative grant provisional recognition to the mineral within the imagined system of classification.

Significance and usage of hetimeve in these works is primarily educational: it provides a concrete example for describing mineral properties, crystallography, and nomenclature. It has no real-world economic value and is not considered a real mineral outside of fictional contexts.
