Glorantha is not a planet, as is ours, but instead is a slightly bulging, squarish lozenge, like the Earth Rune’s shape. Glorantha floats upon Sramak’s River, the Primal Ocean that encircles the world. The Sky overhead is an off center bowl rotating about the Pole Star which marks the center of the Sky, and is the only stable point in the celestial dome. Between the Earth and Sky is the turbulent realm of the Air gods. Underneath both Earth and Water is the dark, silent Underworld.
