ichersiees

Ichersiees is a fictional mineral described in speculative fiction and worldbuilding literature. It is portrayed as a rare silicate-bearing mineral that forms in extreme hydrothermal environments. Within the fictional setting, ichersiees is notable for a shimmering iridescence, high electrical conductivity, and remarkable stability under pressure and heat.

The name ichersiees is a neologism created for fiction; there is no established real-world etymology outside the fictional corpus. It is treated in-universe as the formal designation of a mineral, rather than a descriptive word.

In the in-universe chronology, ichersiees was first documented during deep-sea drilling campaigns conducted by a multinational expedition. Subsequent analyses in fictional journals describe its occurrence as scarce, confined to vent fields, and associated with distinctive mineral assemblages that include veined silicates and conductive phases.

Reported physical and chemical characteristics are described as orthorhombic crystals with a Mohs hardness around 6.5, a density near 5.2 g/cm3, and a generalized composition written as (Fe, Mn, REE)2SiO4 with trace elements. It is said to exhibit blue-green iridescence under ultraviolet light and to retain structural integrity under high temperatures and pressures found in vent environments.

Applications within the story span energy storage, photonics, and advanced ceramics. Ichersiees serves as a focal point for plotlines on resource scarcity, scientific collaboration, and the ethical considerations of exploiting rare minerals in a speculative future.
