Obhem

Obhem is a fictional mineral described in the science fantasy universe The Meridian Codex. The term is traced to the Vecari language, with ob- meaning light and hem denoting bond, highlighting its imagined property of forming luminous, stable connections in devices. In-world, obhem is valued for exceptionally high energy density and resilience to high temperatures and radiation.

Geology and occurrence: Obhem is said to form through late-stage magmatic differentiation followed by hydrothermal alteration. The principal deposits are located in the Obhem Basin on the planet Caelion, with smaller occurrences reported in other systems. Mining is technically complex and politically sensitive due to faulting, gas emissions, and long-term environmental concerns.

Physical properties and handling: Obhem crystals are dark and metallic with a faint blue luminescence when exposed to magnetic fields. In the fiction, refined obhem achieves stable performance in compact energy modules and superconducting coils, while crude obhem must be carefully processed to avoid instability.

Applications and significance: Within the Meridian Codex narrative, obhem powers high-capacity energy storage, propulsion systems for starships, and ceremonial artifacts used in rites. Economically, obhem drives intersystem trade and conflict, with mining rights often a focal point of political negotiation.
