Oooh, I'm getting giddy about the conversation here as it relates to my story.
Me too it seems

Regarding light vs. Dark, I went a little "midichlorian" in that respect. See, what was always known as Light and Dark is discovered (by P&P) to actually be Earthly and Lunar. It works with Cecil's previous journey - he could not overcome his foe with the dark (lunar) sword because his foe was lunar. Likewise, he could master either side because he was the offspring of a lunarian and an earthling.
Palom could never learn White magic BECAUSE he's a twin. One twin got all the lunar power, the other got all of the earthly power.
The plot of my story revolves heavily around the idea that light and dark do not necessarily mean good and evil - evil (and good) can be born from lunar or earthly sources.
For myself I'm OK with that - it works when done right and sounds like a good setup to me! (* See above post Re: Episode III)
(Light/Dark) =/= (Good/Evil) <-- yes sir + I like the explanation for Cecil: nailed it
Of course now I have to ask:

How is Palom going to handle that? Of course I won't ask you to give away anything you don't want to - but it's an internally debated issue for me.
Han Solo (as I understand it) is a good example. I haven't read anything in the Expanded Universe for Star Wars: but I've read a lot about it and I believe that when Han & Leia had children that some of them were stronger with The Force than expected and it was developed that Han is in fact not walking around with an MC of zero - quick reflexes, in both situation analysis and physical dexterity - great pilot, same thinking, etc. - But Han hated that explaination; he felt it took from him the his accomplishment in developing skill 'Born to be better, etc.' - I so envision there Porom being very happy with this discovery and the associated advances in the understanding of magic...
...but at the same time Palom not taking it well. One response is just straight up anger - physically incapible of having become a Sage - that and/or depression. It's an extremely interesting arc to develop I can't wait to play through it someday!

- Slightly off-topic: a couple good Star Wars links I found before Episode III came out:
http://www.theforce.net/swtc/injuries.html- Website originally started in '95 about what exactly happened to Anakin and what limitations Vader has - building towards basically reconstructing what younger Anakin would have had to have been - I'm a fan!
Star Wars: Episode III: Twilight of the Gods by Syndny Cuthbert
(Sci Fi) - It takes place an undefined number of years after the events in 'Attack of the Clones' (Episode II), and tells the story of how Anakin Skywalker finishes his journey to the Dark Side and becomes Lord Darth Vader. (rtf - formatting:
