Soul

The Soul was the immaterial essence of many living things. Transient and virtually immortal, it existed beyond physical life and death.

Mechanics
The soul was the source of life for many living things such as humans, animals, and gods. Lacking a defined shape, it could take on virtually any form. A soul typically inhabited a body, creating a bond tying it to the physical vessel. Should the body experience death, the tie would sever and the soul would depart from the corpse. Likewise, the soul's immaterial nature made it immortal, though it could be theoretically eradicated; similarly, the souls of powerful beings like gods would eventually disappear.

The soul retained a being's innate magical power, the exact amount varying between individuals and species. This power gave the soul a "weight" which could strain the ties between the soul and its body, causing the bond to decay over time until it eventually completely broke down. A soul also possessed a mind, giving it consciousness, memory, and emotion which allowed it to interact with its environment. Despite this, deceased souls lacking a body couldn't normally be perceived by living individuals, though still having several ways to communicate with them such as telepathy. When a soul could be recognized by a physical being, it appeared bright and etheral.

Like biological bodies, the soul could experience physical senses such as hearing, seeing, touching, or tasting. It did not need to eat or sleep to survive. Despite this, a soul could be induced into a state of sleep and still suffered fatigue. Similarly, a soul could still eat at the being's leisure. Souls could also still freely fly through the air in most areas. Certain souls, such as those of gods and their kin, could also affect biological bodies' aging, allowing them to remain physically ageless. However, souls could also carry conditions like Hereditary Evil Raiser Syndrome.
