Tzál

Tzál is a term used in speculative fiction and tabletop role-playing to denote a fictional material with energy-storage properties. In common depictions, tzál appears as a crystalline mineral or alloy that absorbs ambient energy—such as light, heat, or magical flux—and releases it later as light or warmth. Its versatility makes it a frequent plot element as a power source, catalyst for enchantments, or component in advanced technology and armor.

Etymology and naming: The word tzál is a neologism created for worldbuilding and does not correspond to a real-world mineral. Variants in spelling include tzal, tzaal, and tzal, with some authors linking the term to a fictional language or cultural tradition within their setting.

Physical and fictional properties: Tzál is typically described as a translucent or translucent-to-opaque crystal whose color shifts with its energy content. It is portrayed as highly efficient at storing energy but often fragile or brittle, requiring careful handling. Some continuities depict regulatory or safety constraints to prevent energy release from becoming unstable, while others present tzál as a stable, self-contained reservoir.

Applications and cultural role: In narratives, tzál can power portable devices, starship reactors, or magical wards, and it is often mined in distant regions and traded as a valuable commodity. In role-playing games, tzál tokens or ingots may serve as rare crafting components with variable energy value or as a trade good that influences supply and price dynamics within the world.
