Kertalajin

Kertalajin is a fictional mineral that appears in fantasy literature and tabletop role-playing games. It is described as a rare, luminescent crystal capable of storing and channeling magical energy. In most depictions, kertalajin forms in deep, heat-driven geologic environments, though its exact formation is often left ambiguous to emphasize its mythic status. The term itself has no single canonical etymology and is commonly presented as an invented compound name drawn from generic fantasy-sounding roots.

Properties commonly attributed to kertalajin include a glassy to crystalline lattice and a color range from pale indigo to emerald, often with internal fractures that refract light. It is said to act as a focus or capacitor for arcane power, with energy that tends to leak slowly, requiring careful handling and storage. It is used to power enchanted devices, sigils, or artifacts, and is often employed as a currency or trade good in fictional economies due to its scarcity and potency.

In story and game contexts, kertalajin is typically mined by specialized prospectors or extracted from abandoned ruins; mining is risky due to unstable caverns and residual energetic surges. Synthesis or purification methods appear in some settings but are rarely reliable.

Cultural role: as a plot device, kertalajin can drive quests, influence political power, or serve as a marker of prestige or danger. Variants or substitutes such as aether crystals or mana shards appear in parallel systems.
