Soliseach

Soliseach is a fictional term used in science fiction and fantasy to describe a solar-focused culture, polity, or religious order. It appears across multiple works of worldbuilding and RPG settings without a single canonical definition.

Etymology and usage: The name is constructed from "sol" meaning sun and a suffix "-iseach" commonly invoked in northern European languages to denote leadership or collective identity. Because it is a fictional label, its exact meaning varies by author.

Social and political structure: In many depictions, Soliseach denotes a sun-worshiping theocracy or a council-led state whose legitimacy derives from solar rites. Some portrayals present a merchant oligarchy with a sun-temple as the central institution.

Culture and technology: Cultural hallmarks often include emphasis on daylight, solar calendars, solar-powered devices, light-based architecture, and festival cycles aligned to solstices and equinoxes.

Geography and setting: Soliseach can be placed in arid deserts, sun-drenched coastlands, or high-altitude plateaus; settings vary widely. Its relations with neighboring cultures range from alliance with scholars of light to rivalry with lunar-based factions.

In popular media: The term commonly appears in role-playing games, speculative novels, and worldbuilding resources as a flexible template rather than a fixed nation.
