Crestwater is a prosperous northern duchy threaded by glacial lakes, steep rivers, and enchanted aqueducts. Its glass towers rise above water-driven mills, parchment houses, and lecture halls where battle-mages study beside engineers. Beyond the polished lake cities, highland clans guard pine valleys and cliff roads against winter, monsters, and outside claims. Every settlement depends on controlled water, making broken dams, rogue spirits, and disputed channels threats to the entire region.
