Lessa wakes up in a cold sweat from a confused nightmare, which she cannot remember. She talks with F'lar about her discovery of time-travel, and the surety that someone else must've discovered it before them. F'lar remains convinced that it must be the solution somehow, but can't quite figure out how. F'nor enters, covered in dust, from a patrol in Tillek. F'lar realizes what it was. He interrogates F'nor about when and where the dust storms have been appearing, and discovers that they are precisely where Thread was predicted to fall. It is what happens when Thread goes through cold air.
