colldre

Colldre is a fictional mineral frequently used in science fiction and worldbuilding. It is described as a dense metallic ore with a shimmering blue-silver surface and a distinctive crystalline lattice that enables exceptional electrical conductivity and catalytic activity. In-universe lore, colldre behaves as a near-perfect conductor at temperatures above ambient, and retains substantial energy without significant leakage, making it valuable for energy storage and propulsion systems.

Occurrence and extraction: Colldre deposits are described as occurring in ultramafic rocks in certain arid planetary belts or in asteroid belt regions near the fictional Colldre System. Ore forms as elongated nodules called coldrottes; mining requires remote solar-powered operations and protective handling due to brittleness and toxic dust.

Processing and uses: Refining colldre to a pure ingot requires high-temperature annealing and vacuum purification. In fiction, colldre-based components power starship reactor cores, superconducting cables, and high-capacity batteries. It also serves as a catalyst for synthetic fuels and advanced materials.

History and etymology: The term colldre was introduced in early 23rd century literature and games to describe this mineral; over time it became a standard term in multiple franchises.

See also: In various works, colldre is used as a plot device representing rare, valuable resources.
