The Life Sphere is one of the four fundamental aspects of reality in The Twenty Domains magic system of Tarras. It represents living things, vitality, and mortality—the essence of biological existence and the forces that sustain or end it.
The Life Sphere intersects with each of the five Elders to create five distinct domains:
Practitioners who study multiple domains within the Life Sphere find it easier to learn adjacent magics than those who jump to different Spheres. A healer studying Life magic might more naturally progress to Death magic (both within Life) than to Creation magic (in the Matter Sphere), despite Life and Creation both being Preservation domains.
The Life Sphere deals fundamentally with the animate, the breathing, the dying—those things that have or had the spark of biological existence. It is concerned with questions of mortality, vitality, and the continuation or cessation of living processes.
