Soul (OT)

A Soul is the incorporeal essence of every living beings.

Anatomy of a soul
Regular souls comprise three parts: logos (the memories), thumos (the instinct) and eros (the hunger; lust). When a being is killed, his thumos goes to the void, disappearing forever, while the thumos and eros are divided and mix with other beings' souls inside the flux of souls, this phenomenon is called soul "reciclyng".
