Frostwinters

Frostwinters is a term used primarily in fantasy literature, role-playing games, and world-building guides to denote recurring periods of extreme cold and snow that shape climates, ecosystems, and societies. It is not a conventional term in real-world meteorology.

Origins and theory: In most settings, Frostwinters arise from cycles in the world's natural or magical order. Some lore ties them to orbital or solar cycles that shorten summers, others attribute them to antagonistic magic or the influence of frost gods or ancestors.

Characteristics: Frostwinters typically last from several weeks to multiple seasons, with subfreezing temperatures, heavy snowfall, icy winds, and frozen waterways. They disrupt agriculture, trade, and travel, prompting migration, fortification, and ritual preparation.

Variation by region and culture: Some regions experience milder Frostwinters with rapid thaw; others endure prolonged, harsher winters. Societies may develop technological and social adaptations, such as insulated architecture, winter economies, and seasonal rituals.

In media and gaming: Frostwinters serve as a narrative backdrop that tests resilience and fosters communal bonds; they appear in novels, tabletop RPG settings, and games as a mechanic that affects resource management, exploration, and combat.
