Ok I was thinking of making the pyramid be some sort of alien Ark that was created by a extinct alien race and the pyramid has been running on its own for years collecting alien species from all over the universe. The robots have been taking people by force, because the central AI which was going to be the brain of the pyramid itself now believes that the universe is going to blow up because it was made to be used in a emergency, but it was accidentally turned on. what do you think?
