Hadrian III is an ice giant in the Hadrian system, United Empire of Earth (UEE). Located in the outer reaches of the system, it has no well-defined solid surface, and instead harbors an ammonia, water, and methane mantle. Its pale green, nearly white atmosphere is broken up by an enormous, permanent dark storm cloud that circles the equator. Inhabitants of Hadrian have nicknamed it "the Watcher" due to its resemblance to a Human eye.
