I knew it! The pyramids were built by an alien race! This is the evidence! A ship landed last night. It seems like they're trying to use the pyramids to charge it. They don't know that all the artifacts and crystals were moved to the museum inside the sphinx. It might be a really old technology for the, because they kinda look lost and clueless. I wonder how they would repay you if you were to tell them about the artifacts and help them open the sphinx. Maybe they'll take you with them! Alright, let's go and show them the way. Good luck!
