There were always people searching for the Unmaker, for some awful destructive power outside themselves. Poor fools, they always thought that Destruction was merely destruction, they were using it and when they were done with it, they’d set to building. But you don’t build on a foundation of destruction. That’s the dark secret of the Unmaker, Alvin thought. Once he sets you to tearing down, it’s hard to get back to building, hard to get your own self back. The digger wears out the ground the spade. And once you let yourself be a tool in the Unmaker’s hand, he’ll wear you out, he’ll tear you down, he’ll dull you and hole you and all the time you’ll be thining you’re so sharp and fine and bright and whole, and you never go till he lets go of you, lets you drop and fall. What’s that clatter? Why, that was me. That was me, sounding like a wore-out tool. What you leaving me for? I still got use left in me?
But you don’t, not when the Unmaker’s got you.
