Solterriana

Solterriana is a term used in various contexts, primarily in fiction and speculative science, to denote either a material or a place associated with solar and terrestrial imagery. The word derives from sol, the Latin for sun, and terra, for earth, reflecting its sun-earth connotations. In speculative fiction and world-building, solterriana commonly appears as a luminescent crystal or mineral prized for its supposed ability to absorb and store solar energy, or to emit light after dusk. It is often described as heat- or radiation-resistant and valuable for technology, construction, or ceremonial purposes, though the exact properties vary by author.

In other uses, solterriana can designate a fictional planet, region, or mineral resource within a fictional setting, sometimes serving as a central element of the economy or culture in that world. In fantasy contexts, it may symbolize harmony between solar forces and earthly life, appearing in myths or religious allegory.

Not a real material or celestial body is recognized in current scientific literature; solterriana remains a literary or speculative term. The concept appears across different media and is typically defined within its specific work, with details left to the author or designer.

References to solterriana, when present, usually point to the particular work rather than to a standardized scientific or geographic entry. See also entries for similar fictional substances such as solarite or terralith.
