Well, having read this entire thread thus far (I sh*t you not) and from my nagging feelings having read the series over the years, there's two things that keep coming back to me as being possibilities and, thanks to this thread, I've a crackpot theory too! ;D
Now, I know these two thoughts should be precluded by the "Theoryland List" and have likely been discussed ad-nausea but I can't shake them.
Thought the First - The Twisted Red Doorways.
Yes, I know - done to death but the thing that has ALWAYS bugged me is when Rand, Mat and Moiraine are all in Aelfinnland (TSR, Ch 15) they never see each other yet they all exit within a short space of time. How come? Do the Finns create a new 'reality' for each person that enters? Insofar that they have singular and seperate experiences at the same time they are in the same place? And these places would somehow have to be linked due to the "strain" part. Gah! Mashes my head to a pulp this one.
Anyhoo, the point being that when Moiraine and Lanfear fall through the Rhuidean doorway, are they also seperated as we saw in the Tear doorway? What bearing would this have? Moiraine sits there all Zen, refusing to play the Finn's games and waiting to be rescued while Lanny goes bat-shit crazy and is killed for it? I suppose we'll find out come autumn.
Thought the Second - Mat's Foxhead Medallion
Yes, I know, discussed to death. However, it constantly occurs to me that Elayne could make many copies of the medallion, and they could be handed out to Rand's army/channelers/etc. I know that weaves evaporate when directed toward the wearer of the medallion but I'm pretty sure we've no knowledge of what happens if a channeler wears one? Very cool if you could throw weaves at a Dreadlord and be protected from direct a retaliation of weaves.
Having read the Mistborn trilogy, these are the things that strike me to be most akin to an earring-type-thingumybob.
Loony Theory - Min/Finn
It's Dida's fault for posting the below quote:
Go on, tell me that doesn't sound just a little bit like Min's ability? Studied the air above his head?? :o Bloody brilliant!!! What if this is somehow related? I'd love it to be. Love it. ;)
Anyway, I told you it was loony.
Well, apologies for length if not the content. Let me know how I'm insanely wide of the mark at your leisure. Cheers. ;D
PS, it is a bloody good hat.
