Soul

Souls are what define a person on Aerb. They contain all the information about the person and more. When a person dies after a certain period of time they get sent to hell. Thus it is customary for people to store the soul after a person dies and before they depart to Hell.

Technology in this world largely uses souls as their power source. People on Aerb don't believe in anything like Heaven and have found no proof it exists. The same cannot be said about Hell however, as they have definite proof it exists and demons can even come to Aerb from one of the nine thousand hells.

Nonanima are people with no soul. They can be taken over by a Demon at any given time and are not considered a person.
