Kahvan

Kahvan is a fictional mineral commonly referenced in fantasy literature and worldbuilding. Described as a rare, luminescent crystal, kahvan is said to form in deep basaltic environments through slow hydrothermal processes. Crystals are typically pale blue to emerald green and emit a soft glow when exposed to electric or magnetic fields.

In many settings kahvan is highly valued for its durability and light-emitting qualities. It is used in jewelry, carved sigils, and components for energy storage in magical devices. Some narratives claim kahvan can stabilize enchantments or channel ambient magic, though such claims are artistically variable and not scientifically grounded within the fiction.

Etymology traces the name to ancient texts from a region called the Karish plateau; earliest references appear in chronicles dating to roughly the 8th century in several fictional languages. In worldbuilding discussions, kahvan mining is described as high-risk due to thin veins, complex geology, and political conflicts over control of deposits.

In practice for writers and creators, kahvan offers an aesthetic and plausible material basis for artifacts and technologies within a fantasy economy. Its properties can be adapted to fit different narrative needs, from ornamental to functional roles in devices or spells.
