Witheters is a lush mountain valley centered around a monumental city-state and its surrounding feudal estates. High peaks frame a landscape of ancient stone castles and impossibly rich soil. At the heart of the capital stands the Great Arbiter, a colossal tree that has begun blooming after centuries of dormant death. While its lower limbs pulse with vibrant green leaves, the upper canopy remains a skeletal grey reminder of an age-long blight that once gripped the land.
