varpuð

Varpuð is a fictional mineral and cultural concept in the fantasy setting of Eldoria. It occurs in subterranean basalt veins in the northern highlands, often near geothermal activity. When exposed to air, varpuð emits a pale blue glow and stores heat, a property exploited for illumination, sigil-making, and ceremonial lighting. In rough form, varpuð crystals resemble pale sapphire in color and fracture.

Name and classification: The term varpuð appears in archival Eldorian texts as both a mineral name and a metaphor for illumination. The spelling with eth (ð) denotes the traditional script and is used in most modern translations. Varpuð is classified as a luminescent mineral with magnetic and thermal quirks that set it apart from ordinary crystals.

Occurrence and sources: Varpuð is found in narrow, fault-bound veins in volcanic regions. Deposits are generally small but can be prolific near geothermal vents. Mining is labor-intensive due to fracture zones and heat flux.

Extraction and use: Raw varpuð ore is heated to release volatiles and then refined into crystalline rods and powder. It is used in street lamps, trinket prisms, and circle-work in arcanic rites, where its glow is believed to synchronize with lunar cycles.

Economic and cultural significance: Varpuð markets respond to geothermal activity and political stability in Eldoria. It features in folklore as a sign of safe passage and is commonly associated with guiding travelers at night.
