A deity or god is a powerful being involved in the creation and maintenance of a realm. They are typically worshiped by the inhabitants of the realms they created, as well as the descendants of those inhabitants who have settled elsewhere in the Sora. Deities typically embody one or more physical aspects of reality (such as an element, geographical feature, or creature), metaphysical phenomena (such as magic, death, or dreams), or abstract concepts (such as war, artistry, or love). These are most often known as domains or spheres, with the entire collection called a portfolio, though other terms exist. Most inhabited realms have a pantheon of deities which are responsible for the spiritual advancement of the sapient populace.
