Souls

Souls are the essence of life

Every complex living being possesses a soul, whether it be person, animal or plant

Souls are stored in the hearts, or similar engine cores

Souls naturally grow over time, gaining more mass and becoming more powerful

There are many factors that can influence a soul's growth, or even cause it to shrink

Such factors are for example: Mood, physical and mental health, interaction with other souls, the universe

Souls are mostly passive inside a body, but in certain situations they may take over the brain's functions

If a soul becomes too weak, the living being will die

If a soul becomes too powerful, the living being will also die
