Many have pondered what comes after death or what happens when a new being is brought in existence. No ones knows for sure, some theorize that there is some sort of afterlife, or maybe many types of afterlives. What happens to the souls that get captured and fuel the many Pits of Hell, or those that the angels take into Haven? What about those who have claimed to ventured into Tartarus or other such mystical plains.
What is certain is that most beings have something one could call a Soul. It differs in size and power from creature to creature, a Demon Lord's Soul is a beacon of power where as a unware mortal is more akin to a campfire.
These Souls hold great power and are highly coveted by many beings dealing in magic as many rituals or spells consume them, yet no one knows what happens to the Soul after that.
