I have a logical question, wouldn't the knowledge of at least corrupted Gems be kinda common knowledge? Like, they are giant monsters that have no interest in upholding any masquerade and just kinda rampage around. Plus, wouldn't people ask questions about the giant battlegrounds, Kindergartens, and general Gem tech stuff that was left behind? And this is taking into account that people didn't pass the knowledge of the Gem war down throughout the ages. Assuming that people just say it's superstition, how would they explain the obviously artificial nature of all the Gem tech? I have many questions.
