Soul Seed Creation
Nathan noticed beams of energy radiating from Muramoto's chest. Unlike the Monster Core and Monster Soul Stones he had seen before, these beams were shaped like rotating energy and were incredibly weak as if a single gust of wind could disperse them.
"Rowena," he said, a glimmer of hope in his voice, "what is this?"
Rowena murmured softly, "That is a soul fragment, Master. Imagine it like this: when we eat fruit, it leaves behind seeds, and those seeds can grow into other fruits."
Nathan remained silent for a moment, listening intently for any further explanations from Luna.
