So the Dark did a simple thing. They showed the maker of the sword his own uncertainty and fear. Fear of having done the wrong thing--fear that having done this one great thing, he would never again be able to accomplish anything of great worth--fear of age, of insufficiency, of unmet promise. All such great fears, that are the doom of people given the gift of making, and lie always somewhere in their minds.
