Starari is a spherical ‘Prime Material Plane’ that floats through the Dimensional Void. The Moon, Sun, stars and planetoids aren’t actually physical spheres, but a mortal’s perception of the infinite planes that border Starari through the Dimensional Void. The Moon represents the Astral Plane, while the Sun is the Positive Energy Plane. Eclipses are actually when the two involved planes become coterminous in particular ways; a total eclipse of the Sun typically makes arcane magic very powerful. A total eclipse of the Moon (aka, a Blood Moon) makes necromantic rituals particularly powerful, as it actually causes a small rift to be temporarily opened into the Negative Energy Plane.
