Lekkivus

Lekkivus is a term used primarily in speculative fiction and world-building communities to denote a fictional material, phenomenon, or resource. There is no consensus or real-world definition, and the meaning of lekkivus varies between works. The name appears as a neologism created by authors or fan communities, with no standardized etymology.

In fiction, lekkivus is typically described as a rare and valuable entity whose properties intersect science and mysticism. It has been imagined as a luminescent mineral that stores energy, a substance capable of powering advanced technologies, or a data medium that encodes information in its lattice. Some writers treat lekkivus as an alien artifact that can influence physical laws, while others use it as a catalyst for social or political conflict, such as resource competition or technological monopolies. Because of its variable nature, lekkivus serves as a flexible plot device enabling world-building around scarcity, trade, and ethics.

In practice, references to lekkivus mostly appear in fan wikis, tabletop role-playing game guides, or short fiction. It is not recognized by scientific disciplines, and its properties are intentionally inconsistent to suit individual narratives.
