Excellent parallels, although BA makes a good point about the White Council being a bit more compromising. However, I think the gist is the same.
It would be Jim's style to have been hitting us in the face with a cluebat with all those Star Wars comments and no one realise how close he was.
However, I always think about something my old man used to say about coincidences. He said that you can always find similarities between things, but often the differences were greater. It was only when the differences did not outweigh the similarities that it becomes significant. He was being general of course, but that's the point.
As Morris says, Star Wars borrowed a lot of stuff itself so Jim could also be borrowing from the same sources.
But if we continue down this road let's think of some more parallels, but from the original trilogy.
1. If Dresden is Luke, then who is Vader. Justin? Eb?
2. The Emperor (we even have an Empress in the Fomor) is a ruling threat.
3. A super weapon is in the wings - Demonreach?
4. Thomas is Han?
5. Elaine is probably Leia.
6. Ben Kenobi is Eb.
7. Yoda is Vadderung, perhaps?
8. After striking well at the enemy, the enemy hits back = Changes versus Peace Talks perhaps?
I like your parallel to prequel trilogy better though. Wouldn't be surprised (if Jim is borrowing) if the books are a combination of the two.
