“magic of a kind, I think. Not the usual sort. I mean, it can turn gold into copper while at the same time it is still gold, it makes men rich by destroying their possessions, it allows the weak to walk fearlessly among thieves, it passes through the strongest doors to leach the most protected treasuries. Even now it has me enslaved—so that I must follow this madman willynilly and protect him from harm. It’s stronger than you, Bravd. It is, I think, more cunning even than you, Weasel.” “What is it called then, this mighty magic?” Rincewind shrugged. “In our tongue it is called reflected-sound-as-of-underground-spirits.”
