After the experience Feng Yu had taken him through on Pohnpei Island, Lu Ban had already roughly figured out the nature of these missions in the Silent Lands.
It was that the true Divine Beings had plucked a piece of history from a Foreign Domain, using it as a stage, sending in the Chosen by Gods to realize the outcomes they desired, and after achieving these, returning that segment of history to its original place.
For these Divine Beings, every mission in a Foreign Domain was like an unread part of a novel; they could jump to the beginning or the end at will. Throwing the Chosen by Gods into the mix was akin to a black box operation.
They were observers of a higher order than the Chosen by Gods. If Mortals were NPCs in the story, oblivious to the timeline changes to the Chosen by Gods, then the Chosen by Gods were similarly toys to the Divine Beings, unaware of the timeline's alterations.
