The oath Kvothe swears to Denna "I swear i wont attempt to uncover your patron, I swear it on my name and my power. I swear it by my good left hand. I swear it by the ever-moving moon."
In the present he goes by 'Kote'
He hasn't shone any power as a namer, failed the sole attempt at sympathy we've seen, and his martial prowess has failed him.
He doesnt play music anymore. ("The left hand is clever" and I belive Kvothe mentions it in conection with his music at the time)
I belive that also connected is "...the story told of how Kvothe had gone looking for his hearts desire. He had to trick a demon to get it. But once it rested in his hand, he was forced to fight an angel to keep it." followed by an "I can belive it. This is the face of a man who has killed an angel"
I think that
'His hearts desire' is denna
Demon=one or more of The Seven
and the Angel is one of those raised at the end of the creation war in Skarpi story.
But if thats true the just what is Denna? Or maybe its Kvothe thats so special? Or Maybe niether maybe its something else?
On a seperate note prehaps Bredon, or Stapes(or even Dagon) are related to the Amyr what do you guys think?
