Ok so somethings I'm seeing is that people don't really know what the souls are ok let me explain in greater detail let's start with the easiest soul color "green" green stands for kindness having a green soul means you have always been kind to others and never fought people.

Another soul would be "purple" that soul represents you going forward no matter what also known as perseverance.

The souls are there so you can pick which one suits your character or you. An example of this is bas both evil and good in a way a perfect soul for her would be the duality soul which is both good and bad.

Hope this explain atleast some of it
