Tarqal

Tarqal is a fictional mineral referenced in fantasy and science fiction media, including novels, role-playing games, and film tie-ins. In most depictions, tarqal crystals are found in deep volcanic or tectonically active regions and are valued for their ability to store and release energy. The crystals are described as vitreous and glassy, often with a luminescent glow that shifts from blue to green. The chemical composition of tarqal is intentionally variable across sources, reinforcing its role as a narrative device rather than a defined material.

In-universe, tarqal powers arcane devices, crystalline conduits, differential amplifiers for psionic or magical effects, and sometimes compact reactors. Processing tarqal typically requires careful heating, annealing, and atmospherically controlled refining to prevent cracking or toxic byproducts. Mining tarqal is depicted as hazardous due to heat, gas emissions, and structural instability, leading to specialized mining teams and safety protocols in many stories.

Etymologically, tarqal is presented as a loanword from a fictional language family, with multiple spellings in different cultures within the setting. The mineral appears across works with varying lore, allowing it to function as a shared but noncanonical element among authors. In summary, tarqal serves as a versatile fictional mineral emblematic of advanced energy technologies and mystic resonance. When encountering tarqal in a particular work, the source should be consulted for the specific properties and context assigned there.
