Death

Death comes to all things, or so it is meant to be. Even the gods can die. Yet so few understand death, either the phenomenon or the entity.
Death is the inevitability necessitated by the existence of life. Before there was anything there was everything. When everything became tired of itself it made more; smashing itself to pieces and allowing the fragments to reform, learn and experience each other.
Physics attempts to explain this phenomenon of creation, and will continue to do so as the laws by which reality began are not the laws by which it functions. The closest mortals, and many gods, will ever come to understand reality is in its cycles of existence.
The analogy favored among many is the act of breathing. Upon inhale the universe is born, matter scattered and life begins. Upon exhale the heat death of the universe condenses all back to a singular point where it prepares of expansion upon the next breath.
While life happens so to does death. The souls that exist as fragments of memory, energy and intent house themselves amongst matter, living in shells of isolated experiences until that shell dies. The act of dying is often terrifying as few souls retain memory of the veil and what comes beyond. In their fear they fight the act of dying.
To die is to be reborn, the matter decayed into new purpose, the soul traversing the veil towards the forge of creation where its memories and experiences can be reintegrated into what was once everything; refashioned into a semblance of itself and yet also new to go forth and exist once more within matter.
The law of death is overseen by the deity Death. A God to some, an inevitability to others, a monster to more. Death has gone by many names over the Eons and cycles, they have even changed from time to time. When Death changes itself they become a new version of themselves. A process which frees the previous Death to explore new planes of reality.
Though Death oversees the law of death the souls are ushered by lesser aspects of the deity often referred to as reapers. These shadows of a god are ferrymen, guides and jailors to the souls who hesitate on their journey through the veil.

"…the absence of the god of Death does not remove the natural process. Things will always die; souls will always enter the veil. In most cases those souls will be guided by the small fragments that Death uses for that express purpose, some call them reapers…”
