Tanmlanrken

Tanmlanrken is a fictional mineral described in speculative fiction and tabletop role-playing texts. In the imagined world, it is a dense crystalline material notable for high radiation tolerance and energy-absorption capabilities, making it valuable for advanced shielding and energy systems.

The name tanmlanrken is an in-universe coinage, with no real-world linguistic origin. Within the narrative, it is attributed to early prospectors from the Iskandra Arc who first identified the mineral in metamorphic rock formations.

Tanmlanrken is described as extremely hard (approximately Mohs 8.5–9) with a melting point well above 3000°C. It exhibits low thermal expansion and a high dielectric constant, and under neutron irradiation it develops a luminescent glow that researchers exploit for non-destructive testing. Processing requires high-purity, inert-atmosphere furnaces and meticulous crystalline orientation to prevent fracture.

Deposits: In the fiction, tanmlanrken deposits occur primarily in deep-vein systems in the Iskandra plateau and are also found in trace quantities on certain exterior rings of outer solar-system bodies. Economically, supply is controlled by a small number of mining cooperatives and state-backed enterprises.

Applications and significance: Its principal uses are shield structures for starships and fusion reactors, radiation-hardened optical components, and energy-storage matrices in theoretical superconducting grids. The mineral's scarcity and extraction difficulty often drive geopolitical tensions in the story world.

Notes: Tanmlanrken is a fictional construct used across various works; see in-universe handbooks and fiction for details.
