It seems to me that RJ is going to bring us farther with all the CHAOS bull. The first time that Chaos is mentioned is in the Great Hunt, when Rand is going to Portal Stone over to Falme. Verin mentions that the Portal Stones were created by those who knew the Numbers of Chaos. Later, is the Prologue of LOC, we hear the choas stuff (even in the title) with the Unseen Watcher, thinking about small differences in Chaos are as important as large differences. I think that Chaos might have something to do with either: 1) the one power/true power 2) the gates to Aelfinn and Eelfinn 3) Tel'aran'rhiod
