He says in several of the books or several times in the same one he is very good at Thaumaturgy.  IE making blasting rods, staffs, armored coats, energy rings, shield bracelets and finding things!  That is Harry's specialty!

He is talking about Susan killing him and becoming a person who is familiar but not really.  Her transformation into a full blood red court vampire!

LOL. So much input on the relationship front.  I don't think Harry will end up with either Molly or Karrin.  I am pretty sure he will end up with Lash.  

I know it seems like a stretch but hear me out.  Bob said that Lash took a piece of Harry's soul.  We know Harry was rewarded for turning down a fallen angel with soulfire.  It is not unreasonable to assume that Lash was also given a reward.  Remember Harry has free will and was able to make a choice.  Lash is a shadow of Lasciel and has a nature.  She rebelled against her nature, the nature of a Fallen Angel. I  think she will be rewarded with the gift of being human.  Though it is possible she has become an angel and is the one truly sponsoring Harry's soulfire!

I would also like to add that Harry as the Winter Knight amplifying his own power plus the sponsored soulfire has to be close to the same power as that of the senior council.   I doubt that many off the senior council would be much of a match for Harry!

The white council needs Molly.  Their training in defensive mental magic is sub par at best.  I suspect that she is well ahead of 90% of the White Council in defensive mind magic.  Hell, she lasted way longer against Corpse-taker than either Harry or Lucio ever managed.  

Jim goes into very great detail about Warden Swords in the books.  Can't remember what book it is but it is very specific and repeated in many of them.  I do recall them being referred to as "silver sword of the Wardens"  Dead Beat, chapter 39. 

Captain Luccio  explains to Harry about Warden swords in White Knight!   Check out Chapter 22 of White Knight if you want to know why. That will explain everything without me posting spoilers! I can state that they are definitely not mass produced and it is very unlikelyt for them to be inherited. 

I loved looking at your take on the characters.  Though I think I would add an Aspect for Ancient Mai.  I would add the aspect "Dresden has a Foo dog".  This aspect could be good or negative depending on how you want to use it.

I know you don't normally add aspects for small events, but I am pretty sure the small comment she makes in Turn Coat is gonna be huge later in the books.  I am also very confident that here opinion of Harry Dresden has changed and may influence her actions later in the series.  She is the creator of the Foo dog statues and there is a reason she modeled them after a Foo dog.
