So he really meant it when he said his own people were trash. The only moon people left are the ones with the most negative karma.
Also, after rogue AI, it only makes sense to restrain other sentient machines. Seems Adamant is the victim of over-correcting on that front.
At this point, I have no idea how this could work out.
Phos isn't is their right mind, the moon gems are along for the ride, and the earth gems aren't about to listen. Nobody is in the right.
