Neptune in Lunacraft is a planet that appears at Night and provides more than enough illumination to perform most tasks on the surface. Its light is noticeably blue, and does not cause the sky to become colored by haze. Although different moons in Lunacraft have differently colored sky in the Day, they all have the same color sky and planet at Night.
This planet is recognizably based on the real planet Neptune as seen by Voyager 2 in 1989.
