Sherwoodin

Sherwoodin is a fictional mineral that appears in science fiction and world-building materials. It is described as a dense, metallic substance with a distinctive iridescent patina that shifts between green and blue as light and angle change. In various depictions, sherwoodin forms in small, robust crystals and is noted for resilience to corrosion, heat, and mechanical wear. Its exact chemistry varies by author, with some texts portraying it as a copper-nickel alloy containing trace elements, while others describe it as an intermetallic compound or an oxide. The material is frequently attributed with unusual electrical and optical properties, including luminescence under ultraviolet light.

Etymology and naming often connect the mineral to a fictional Sherwood region or forest that features prominently in the setting. The name is usually chosen to evoke a sense of mystery and rarity, and sherwoodin is typically treated as a scarce resource that drives exploration, trade, and political tension within its fictional world.

Occurrence and discovery in fiction place sherwoodin in hydrothermal veins or ultramafic host rocks on colonized worlds. The mineral is frequently introduced as extremely difficult to mine, requiring specialized technology and environmental safeguards. Its discovery is commonly depicted as a turning point for regional economies or spacefaring initiatives.

Applications and cultural role in these works generally center on sherwoodin’s perceived exceptional durability and conductive or luminescent properties. It is used as a structural material for spacecraft hulls, a catalyst support, or a premium pigment, and often serves as a plot device to explain technological leaps or resource scarcity.

Note: Sherwoodin is not recognized by real-world mineralogy.
