The Sphere Mythos is a collection of stories concerning Jeff and Millie, two Occult researchers, who have discovered a pantheon of ancient gods known as Spheres. There are four categories of Spheres: Ruin Spheres, associated wit Fire; Will Spheres, associated with Wind; Life Spheres, associated with Water; and Truth Spheres, associated with Earth. Ruin Spheres are the most often encountered Spheres throughout the Mythos, and the ones with the most development as of now.
