“Matoro and the Makuta did not come back, for a simple reason. None of them have bodies anymore. The body is what is teleported up (which is why you don’t see BIONICLE graveyards) and then either repaired or a new one is made to house the consciousness. If the body has been utterly destroyed, there is nothing to work with.”
I love this story, by the way. I usually try to avoid reading fanfaction so as not to get attached to a “non-canon” story, but this one sucked me in. You’ve done a great job of mimicking the original writing and dialogue style. And I like that the “fan addons” are kept to a minimum; it’s mostly based directly on actual canon events and characters.
