Zboach

Zboach is a fictional mineral often described in speculative geology and fantasy fiction. In common depictions, zboach is a silicate with an iridescent sheen and a high refractive index, forming under extreme metamorphic conditions. It is valued for stability at high temperatures and is said to channel energy in magical inscriptions or advanced optics within the imagined world.

The term first appeared in late 19th-century adventure geology texts, though different canons attribute its origin to a fictional language of the Zboar region. Descriptions vary by author, but most share a core concept: zboach as a rare, energy-responsive mineral.

Geologically, zboach is placed in ultramafic and meta-ultramafic belts, often in contact zones where hydrothermal fluids crystallize it into prismatic crystals up to several centimeters. It is commonly described with inclusion-rich matrices that produce a prismatic brilliance when light passes through.

Physical properties commonly cited include Mohs hardness around 7 to 8, a glassy to resinous luster, and colors ranging from icy blue to violet or green. The streak is pale, and cleavage is imperfect, producing splintery fracture surfaces.

Uses and symbolism: In fictional economies, zboach is mined for jewelry, lenses, and talismans. Its reputed ability to stabilize enchantments or concentrate thermal energy makes it valuable to spellcasters and engineers in various stories. Mining and processing are described as hazardous due to fine dust and toxic fluids in some narratives.

In literature and media, zboach appears in encyclopedias of fantasy minerals, role-playing games, and world-building guides as a symbol of rarity and arcane knowledge. In reality, zboach is a fictional mineral and is not recognized by real-world geological authorities.
