The expression can be traced to the Third Centennial Apert, when the gates of several Hundreder maths opened to reveal startling outcomes, e. g.: at Saunt Rambalf's, a mass suicide that had taken place only moments earlier. At Saunt Terramore's, nothing at all - not even human remains. At Saunt Byadin's, a previously unheard-of religious sect.... At Saunt Lesper's, no humans, but a previously undiscovered species of tree-dwelling higher primates.
