The Crown Oasis, also called Virdal Valley, is Verulana’s verdant heart and its most contested resource basin. Palm groves, terraced farms, and polished quartzite cities thrive because ancient leyline aquifers draw pure water from the Elemental Plane of Water. Beneath the bright markets lies a second landscape of reservoirs, temples, flooded passages, and unstable channels. Every harvest, treaty, and political bargain depends on the water moving safely.
