A Crown of Swords book tour
Aelfinn, Matrim Cauthon, Tel'aran'rhiod, stedding
Robert Jordan has spoken...
Also, what was going on in Aelfland when Mat went round and round and round the same location? Were they traveling in time?
Not traveling in time. the physical laws of nature differ. Mentioning the Dark One here is bad luck. In Aelfland, it is really bad. You can not go to Aelfland in Tel'aran'rhiod (similar to stedding).
