"I do not need or take souls. What would I do with them?" Lucy snorted. "The soul is the seat of memory, and memory is the core of existence. The heart is the home of emotion, and emotion with memory is the truth of meaning. A soul without a heart is memory without meaning, while a heart without a soul is emotion with no purpose. A being requires both in order to function."
She took another look at the woman before her. Ah, that explained much - this one and the others like her were lost souls, seeking meaning and a reason for being.
