Eskein

Eskein is a fictional mineral described in science fiction literature and media. It is characterized as a rare, conductive crystalline substance capable of storing and transferring large amounts of energy, and is commonly used in starship power systems and high-performance computing within the works.

Discovery and name: The mineral first appears in late-22nd-century narratives by the author L. M. Korrin. The name Eskein is derived from the Eskean language featured in the series, where it translates roughly as "core light."

Properties: In-universe descriptions assign Eskein a metallic luster and hexagonal crystal habit. It is highly thermally stable and exhibits nonlinear electrical properties, allowing rapid charge and discharge cycles. Physical hardness is described as high, with reactions sensitive to magnetic fields, though exact figures vary by edition.

Occurrence and processing: Eskein is reported to form in mantle-like pockets beneath certain exoplanetary crusts, and its extraction requires deep, high-pressure mining and subsequent vacuum processing to prevent oxidation. Refining yields a purer phase suitable for energy-density applications.

Applications and significance: Eskein serves as a central techno-arc element, enabling long-range propulsion, inertial dampening, and advanced computation in the narrative. It also functions as a plot device for trade dynamics and political tension, given its scarcity and regulation.

Etymology and status: The term derives from the Eskean language within the fictional universe, reinforcing its contextual meaning as a concentrated source of energy. In-world discussions emphasize scarcity, regulation, and environmental considerations surrounding its use.
