“About a thousand years ago, during what you humans call the War of the Hundred Years, the Ways began to change. So slowly in the beginning that none really noticed, they grew dank and dim. Then darkness fell along the bridges. Some who went in were never seen again. Travelers spoke of being watched from the dark. The numbers who vanished grew, and some who came out had gone mad, raving about Machin Shin, the Black Wind.” (Wheel of Time)
