King Midas’s gold is the largest amount of gold that has ever been safely secured by a human King. The order have safely guarded this gold in a very specific location that is never going to be possible for humans to see. The order would never trust the task of protecting this gold to humans and this is the reason why they hired alien lifeforms to guard it. These creatures have been given instructions to destroy anything or anyone that comes within miles of the location of the gold.
They have been protecting this gold for centuries and this is the only reason why they are on Earth. Perhaps the order will one day allow for humans to see this gold and to put it to use, but this is not going to be happening anytime soon. The guardians of the gold are extremely powerful creatures that no human could ever be able to defeat, even with the most powerful human weapons. Not even with nuclear power.
