Wait a minute. O.o 

If the PC gods can't create souls, what can? 

Is there an even more powerful type of god? And if so is it actually a different thing from the types of gods we are to play as? Or is it something that only ancient gods can do or some other factor that alters the type of god we would be playing? Or is there some other specialized deity or force that cannot do anything else but create souls? 

Edit: Or is it the Godeater? Does that thing actually tear apart the essence of a god and convert the scraps of such a broken divinity into the souls of the unborn?
