Spirits

A soul is the core and identity of any entity and contains all information related to its life, its will and its behavior. A soul can't exist on its own and needs to be fixed to some kind of structure, either magical or physical. Over time, the souls is shaped to fit its container. The most common being the brains, the soul stones and the spirit cores.

If the soul's container is broken or dies, the soul will slowly dissolve over time and return to be energy. In some case the soul will try to keep its integrity and rarely soul manages to survive due to an extreme will as well as some other factors and become wandering souls.

A wandering soul, or ghost, is an unstable collection of soul fragments without a container that act unconsciously relative to the remaining information it possesses. It generally can't interact with the physical or magical world and slowly dissipate while trying to survive by assimilating more souls.

It can happen that wandering souls accumulate enough energy to form a spiritual core, giving birth to a spirit. When becoming a spirit, the soul is stabilized and regains its consciousness. Some spirits can use magic or influence the physical world and they generally have a medium that keep their soul from dissipating. Due to the succession of extremely rare circumstances, those kinds of entities are extremely rare in the wilderness. Elementals are spirit who has the ability to control a element.

Spirits can be created artificially by fixing a soul into an medium through magic and force the creation of the spiritual core within it. Unlike naturally formed spirit who got their consciousness stabilized, artificial spirit may have a partial consciousness or an unstable personality.

In simple terms, a spirit is a conscious soul that doesn't possess a traditional body and that may have magical abilities.
