sóun

Sóun is a term used in fictional universes to denote a rare mineral that functions as an energy storage and lighting material in fantasy settings. It is not a real mineral.

In common depictions, sóun is described as a translucent, blue-green crystal that absorbs light from nearby sources and releases it gradually. It is typically found in deep mountainous deposits and requires specialized mining practices. Its energy density and recharging behavior vary by author, but recurring themes include long-lasting luminescence and stability across a wide range of temperatures. When fashioned into cylinders or blades, sóun-based devices can power torches, lanterns, and basic arcane engines for extended periods.

Etymology and usage: The name derives from a constructed language created for the fictional works in which sóun appears; meanings vary but are often linked to light or memory. The term has been adopted by fans and role-playing communities as a generic descriptor for similar fictional minerals.

Cultural and economic context: In narrative contexts, sóun often carries symbolic weight, representing knowledge, endurance, or taboo wealth. Economically within stories, it is regulated, traded with difficulty, and controlled by mining guilds or authorities; licensing and export rules may be plot elements.
