ULC the wall

an archeological discovery was found at ____ ____ while some anonymous teens were exploring the desert and mining into some caves for expensive ores but as they reached the end of the deepest cave they mined a heavy and indestructible wall created out of an unknown substance
the wall took the entire surroundings of the cave meaning that it was much longer and larger then expected however that is all that it is a wall
until we used an xray camera to see what was inside and we've discovered that the inside was hollows and that a Chrystal was resting on some kind of display a few people seemed to be kneeling before it these people seemed to be some kind of zombies as they're skeleton were exposed in some places of they're bodies.
for now we do not have the technology to break through the wall and that's most likely for the better.
nobody should attempt to do so or they will be arrested and they're memories erased if none of these options work then they will be eliminated.
