The Matter Sphere is one of the four fundamental aspects of reality in The Twenty Domains magic system of Tarras. It represents physical substance and manipulation—the realm of tangible objects, materials, and the transformation of the physical world.
The Matter Sphere intersects with each of the five Elders to create five distinct domains:
Practitioners who study multiple domains within the Matter Sphere find it easier to learn adjacent magics than those who jump to different Spheres. A practitioner of Ward magic might more easily grasp Creation than Conjuration (in the Life Sphere), despite both Ward and Conjuration being Void domains.
The Matter Sphere deals fundamentally with the physical, the tangible, the stuff of reality itself. It is concerned with the formation, manipulation, protection, and destruction of material substance—everything from the mightiest fortress wall to the smallest grain of sand.
