Soul
From Soloralwiki
In Soloralism, a soul is the total sum of the distribution of the quintessences of an individual living being. It is similiar to the concept of a soul or spirit in many other religions. However, a soul is a conglomerate of the various quintessences, instead of being made out of something homogeneous.
The concept of a soul is intertwined with the concept of Empathi Energy. A soul is empathi energy that is confined within a living being. A being who is consisted completely of one quintessence is an Avatar.
While a soul is defined as confined empathi energy, souls can be transfered between beings. See Soul Swapping.
