Akrual

Akrual is a fictional crystalline mineral described in speculative fiction and role-playing game lore. It is characterized by a translucent, prism-like appearance with a color range from deep teal to violet and an internal sheen that shifts with the viewer’s angle. In-world, akrual is valued for its purported high energy-conductivity and stability, making it a preferred material for arcane focus lenses and compact power cells.

Etymology and naming conventions in the fiction place akrual as a term derived from in-world languages, often interpreted as a compound meaning mirror-core or light-heart. The name evokes its reputed properties of light reflection and energy storage, contributing to its mystique within the narrative setting.

Occurrence and geology are described in official tomes as arising in hydrothermal veins within basalt and ultramafic rock, frequently alongside quartz and tellurides. Akrual deposits are described as extremely rare, with only a limited number of confirmed locations referenced in game materials and lore.

Physical properties and chemistry are presented in-universe as a silicate-like lattice that incorporates trace metals such as iron and manganese. Reported properties include Mohs hardness around 7, refractive index near 1.75, and strong luminescence under ultraviolet light. Akrual is said to be stable at ambient temperatures but capable of increased conductivity when exposed to heat, electric current, or magical energy, a combination that underpins its use in devices described as energy cells or precision lenses.

Uses and significance: In fictional economies, akrual is sought for forging energy storage components, optical sigils, and high-precision focus apparatus. It also features in ceremonial contexts as a symbol of memory or foresight and appears in various media as a coveted, rare material.
