The World Dome cosmological theory is a tenet of Helian theology. It puts forth that the universe exists on the underside of a great bell-shaped dome. At the top of this dome rests the Sun, which is generally considered to be God by the believers of this theory. As one travels down the walls of the dome, the brightness and heat from the Sun gradually decreases and the position of the Sun in the sky approaches the horizon. Eventually, one would encounter the band of Balance, wrapping about the inside of the dome.
