Throughout the reading this story, I took notes; this is something I've learned to do when I'm reading Rothfuss. He inspires so many thoughts all at once that if one doesn't write them down, they overflow, and some just pour out of the trough. 
 So, yes, I took notes. This review isn't comprised of what are exactly spoilers, but rather of somewhat-disjointed examinations of Auri's character based upon her own novella. If you fear spoilers, however, I would proceed with due caution. 
 Here goes: 
 Auri is a linguist, quite fond of words. She combines and recombines them. They reveal connections among each other that she adores. The names she gives to certain rooms in the Underthing-- Annulet, Ninewise, Mantle-- all have proper, logical names based upon their descriptions and/or histories. 
 Auri is much smarter than she seems. Amongst her inner vortex of disconnected thoughts and disjointed observations, there are snippets of severe knowledge. Anatomical definitions and recognitions, chemical observations and descriptions, alchemical knowledge and awareness. She is quite certainly a former student of Master Mandrag, Master of the chemical and alchemical departments at the University- she still remembers and applies his teachings. 
 Auri has incredible impulse control- she views her own body as a separate entity- a stubborn one, in fact- to which she must 'tend.' She can hold her breath for extraordinary periods of time, can go long days without food. She seems to have reached the ultimate detachment from her own body. 
 Auri is immensely frightened of some places: even within the quiet, secure, familiar Underthing. 
 Auri has learned over years to tend to her Underthing: she has also learned to read in the behavior of animals that the Underthing requires tending in the first place. 
 Auri is aware. Do not misunderstand. She knows everything one might think she does not. Even when it comes to the Up Above. 
 Auri unconditionally, ferociously, adoringly loves Kvothe. He is undeniably special to her; the name he gave to her burns bright in her heart, and has saved her from the dark times before. In fact, she had been suffering when she first heard him playing. She looks forward to his visits, and though she is aware of his excess pride, she loves him anyway. Do not misunderstand: I am not claiming a romantic love; he is more even that that: he may be like a younger sibling, or a son, even, who does not know of the world and whom she must teach. All I know is that she loves him, in one way or another. 
 Auri, of course, is aware of the existence of the Fae. 
 Auri feels immensely responsible for the world's very turning-- at times, this is an incredibly heavy burden. 
 Cleanliness is a necessity to Auri. 
 Auri is prepared for when Kvothe finally breaks. She senses its coming, and she has made the necessary provisions to offer him safety and a loving place to stay when he needs it. She is willing to give anything for him; she would even share her own private proper place. He would sleep on a bed close enough to hers that he would be able to sing to her at night. 
 It is becoming more and more certain to me that Auri is not, in fact, the long-lost Tabitha that Simmon once mentioned to Kvothe. 
 Auri has not lost her mind; she is merely slightly broken, and those breaks are wide enough to let more knowledge in than anyone else could possibly hold. A possible exception, of course, is Elodin, who has a similar state of mind. 
 Auri knows of the Amyr, the Ciridae, and has found a connection between them and Kvothe. 
 Auri will one day make a name for Kvothe. 
 Some of us, I imagine, believe this name will be 'Dulator.' After all, Denna has not given him this name yet. 
 But I am not so sure. 
 Lastly, Auri is more powerful than anyone could possibly imagine.
