Rejtznek

Rejtznek is a fictional mineral that appears in speculative fiction and tabletop role-playing games. It is typically portrayed as a rare, luminescent crystalline substance valued for energy-related properties and its potential to power advanced technologies or arcane devices. Across different works, rejtznek is described with varying characteristics, but it is commonly depicted as scarce, costly, and difficult to mine, often in remote or hazardous environments.

Etymology and terminology: The name rejtznek is a constructed neologism created for world-building; there is no standardized origin, and authors use the term independently within their settings.

In-universe properties: Rejtznek crystals are often described as hexagonal prisms or shards with an iridescent, color-shifting sheen. They are typically said to be very hard, comparable to or exceeding corundum, and to emit a faint warmth or resonance when near strong energy fields. Some portrayals attribute energy-storage capabilities or resonance with psionic, magical, or quantum phenomena, though these claims vary by author.

Usage and significance: In fiction and games, rejtznek functions as a valuable resource, a power source, or a catalyst for devices. Its scarcity, price, and extraction risks can drive plotlines from perilous mining expeditions to factional conflicts. In game materials, it may serve as a crafting component, a hard currency, or a limiter or booster for certain abilities.
