Hao Xuan racked his brain and after a brief deliberation concluded that they must be created by the intense emotions that were left behind in a body after its soul departed.
'That's the only thing that makes sense. Once the soul is gone, what does that leave behind? What other thing can have such an obvious manifestation within the Umbral Planes apart from the deepest feelings and sentiments at the time of their death?'
It made sense in Hao Xuan's eyes and unless he saw evidence proving otherwise- he was going to go with that explanation.
'As for the name, let's call them 'motes' for obvious reasons.'
Now that he had a vague idea of what they might be, Hao Xuan wanted to know where they were going so he followed behind the procession as its numbers surpassed two hundred while it cut across the Beast Market and headed to the deck.
They were well out of the range of the barrier now since there weren't even any standing structures left to protect.
