One point as well is that the Amaurotians were obviously very emotionally stunted.
By that i mean there society was ALL about conformity logic etc. Individuals and emotional expression seemingly frowned upon(bar the "wierdos" in elypsis). So of course they couldn't figure it out. As otgers have said they were all happy vibes like kids who have never known anything but happy times. They also overall lacked empathy(this of course goes along with the whole aether blocks dynamis thing)
So given all of that is it any wonder Meteion was so underdeveloped and not able to handle what she found given i doubt anyone on Etherion at the time could have understood or prepared her for it given there clear emotional immaturity.
