Just read both books and loved them, so I'm happy to see this discussion and hope it's still active. I read every post, and some of you have very interesting theories.
Some stuff I've been thinking about:
What does the title mean? (And what happened to Kvothe's powers)?
The Name of the Wind is obvious, but what does The Wise Man's Fear refer to? There's the explicit mention when Felurian tells Kvothe that a wise man fears a moonless night, because that's when the mortal world is pulled closest to the Fae. But it could also refer to something more literal.
Elodin seems to be the wisest man around (what a great character!), and the only time he expresses true fear is when Kvothe asks him about someone who changed their name. This suggests that Kvothe changed more than just his "calling name" when he became Kote, which explains how he lost his powers.
Kvothe retains his physical prowess--he holds Bast by the wrist to prevent Bast from attacking Chronicler and there's a bruise forming afterwards, he kills some scrael, he performs the Ketan "perfectly" at the end of WMF, etc.--which means he could have beaten up the soldiers who robbed him, but chose not to. However, he seems to have lost his magical abilities. When the skinchanger attacks the inn in NotW, Kvothe fails to perform sympathy. Bast later tells Chronicler not to bring this failure up. Also, he tries, but fails, to open the chest at the end of WMF. It seems that Kvothe did what Elodin feared, and is weaker because of it.
Why does Denna always show up? (And do the Amyr or Chandrian know about Kvothe)?
After reading NotW, I thought this was just cute, love-story, coincidence. Maybe she just happened to be in Trebon when he goes looking for the Chandrian. But now it's just too much. She just happens to be in Severin when Kvothe goes to work for the Maer? And she just happens to be in Tarbean when he goes there for a few days? And just happens to burst into the inn where Kvothe is hanging out, unable to breathe? Way too much to be coincidental.
Which means she, or her patron, can track Kvothe. When thugs jump Kvothe in an alley in NotW, he figures out that they have a divining compass (I think that's what it was called) and a piece of his hair or blood, which is why they could find him. Similarly, Devi demands three drops of blood before lending anyone money, which she can use to track (and then hurt) them, if necessary. Denna's patron probably has something similar.
Someone powerful (Amyr? Chandrian?) is obviously keeping tabs on Kvothe, but in a less-than-obvious way, which suggests that they know he has a major role to play. Perhaps opening the Lackless door, as some of you have suggested. This someone is, or is connected to, Denna's patron, who sends her to bump into Kvothe in various locations, and to get close, but not too close. It's possible that Denna is in on it, or is being manipulated herself, but she's definitely manipulating Kvothe. That means that she probably will get him to do the thing that starts the war, which reveals her deception and leaves him feeling betrayed and depressed.
Here's a good place to add my speculation that:
-Bredon is Denna's patron.
-Bredon is the Amyr that's close to the Maer.
-The Amyr aren't "good" in the traditional, pure, good-guys way. They're powerful and opposed to the Chandrian, so they're good in that sense, but they're playing a larger "beautiful game" and willing to do a lot of less-than-good stuff along the way.
Do any of you like Denna?
Just curious. I loved it when she unexpectedly sang with Kvothe and helped him get his pipes, but have liked her less and less as the story went on. I can't decide if Rothfuss wants us to like her or not.
