auditorsille

Auditorsille is a fictional mineral that appears in speculative fiction and worldbuilding exercises. The name combines the concept of accountability, suggested by “auditor,” with the mineral-sounding suffix -sille, signaling its imagined silicate origin. In-universe, auditorsille is often portrayed as a symbol of transparency and traceability, used to explore themes of reliable recordkeeping and oversight.

In terms of appearance and properties, auditorsille is described as a brittle silicate mineral with a vitreous to pearly luster. Reported colors range from pale blue to pale green. Its fictional hardness is typically placed around 5 to 6 on the Mohs scale, and some narratives note a fluorescence under ultraviolet light. Within the lore, a hydrated silicate composition with trace metal inclusions is commonly cited, though exact formulas vary by author.

Geologically, auditorsille is said to form in hydrothermal veins within metamorphic and volcanic rock environments. It is generally considered rare and valuable in the stories where it appears, often tied to secure storage or audit-related symbolism in the fictional economy or setting.

Uses and significance in fiction frequently center on audits and verification themes. Auditorsille may be depicted as seals carved into vault doors, as a material used in truth-telling or verification magic, or as a scarce commodity affecting trade and governance within the narrative world.

Auditorsille has circulated in online worldbuilding resources and tabletop game supplements as an example of a semitransparent, accountability-themed mineral. It is not a real mineral recognized by actual geology.
