In olden times, when mankind was less enlightened, it was thought that exposure to the light of the Moon could cause a person to go insane. This ailment was called "Lunacy." Fortunately we're not so backward anymore. We know that there's nothing to fear from the Moon or the light reflected from its surface. In fact, we now know that the Moon is a place of tranquility and serene beauty. A place where vampires swarm hungrily over the surface of the dark side. A place where werewolves are free to roam, snarling and gnashing, without fear of turning human again. And a place where humans can cower in fear as the resident vampires and werewolves try to slaughter one another, turning the lunar dust red with the blood of monster and innocent alike! Yes, there's nothing remotely insane about the Moon. Nothing at all.
