oflátilra

Oflátilra is a fictional mineral described in speculative fiction, worldbuilding resources, and role-playing settings. It is often used to illustrate the properties and constraints of luminescent silicates and hydrothermal mineralization within imagined planetary systems.

In most depictions, Oflátilra forms as small, prismatic crystals in a tetragonal system. It has a vitreous to pearly luster, a color range from slate gray to iridescent violet, and a Mohs hardness around 5.5–6.0. Reported refractive indices lie near 1.62–1.68, with a density of about 3.1–3.4 g/cm3. A distinctive feature is faint phosphorescence, emitting a blue-green glow for several seconds after exposure to ultraviolet light.

According to fictional sources, Oflátilra develops in high-temperature, reducing environments such as hydrothermal vents or ultramafic intrusion zones. It is often paired with magnetite, olivine, and zircon, and is said to be most abundant on ocean worlds with metallic-rich crusts.

The name Oflátilra is a constructed neologism, coined by fictional geologists in early worldbuilding projects; it has no direct linguistic lineage outside those works.

In fiction, Oflátilra is valued for decorative uses and for speculative energy-storage or luminescent display technologies; in-world lore it often drives plot devices about resource scarcity and planetary mining.
