Tsentreerub

Tsentreerub is a fictional crystalline mineral described in the science fiction setting Arcadia Continuum. It is valued for exceptional stability, high dielectric strength, and luminescent properties. In-universe science, tsentreerub forms in hydrothermal vein deposits within porous basalt and occasionally in asteroid regolith, where it crystallizes as a sparse, prismatic lattice. It is noted for radiation hardness and extreme resistance to thermal cycling, making it suitable for energy storage cores and protective shielding in spacecraft and orbital installations. The mineral emits a ruby-red glow under ultraviolet light and shows a distinct optical anisotropy used for qualitative identification.

Etymology: The name is drawn from the in-world language Tsentra, combining elements meaning 'center' and 'ruby,' reflecting its proposed central role in energy systems.

Discovery and use: First documented by prospectors in the Mictar sector around year 2246 of the Arcadian calendar. Because of its rarity and the difficulty of refining impurities from gangue, tsentreerub has commanded high market value and is controlled by select mining consortia.

In fiction and worldbuilding notes: Tsentreerub is often used as a plot device to explain breakthroughs in energy technology, and appears in technical manuals, trade reports, and cultural artifacts within Arcadia Continuum. The article is a fictional entry for a constructed world.
