Funny you would mention that. I may be mistaken, but he wrote the Sparhawk series, right?
a TANGENT:
I actually played a D&D adaptation (a failed try in BESM and HERO too) that worked very well. Very different. Magic was still restricted, and powerful, but we added some D&D elements. I've actually never read the books, but I feel like I know the story. The GM was really pressed, our group wanted the play and it was her turn to step up, and she needed inspiration, so she used the books. Granted, if the game was movie, people would say "The books are better" well, no, those ARE books, this was a game. Both can be awesome, and the game was. I was lucky enough to play the role of Sparhawk, but with my own reactions, and consequences. I'll tell you...oops. dang it....now I HAVE to use a spoiler.
Spoiler for ACTUAL Spoiler for the...Gems of Eosia...Dunno the name...sadly: (Highlight or hover over the text to view)
Kurik's death scene was heart wrenching. There was foreshadowing, because there was limit resurrection magic, that Kurik wanted stay dead if killed. Just by serendipity, Kurik never actually died...until Zemoch. Adus was attacked by the dim-witted friend, another PC, and Adus killed him too, on counter attack...and then happened to go on the initiative right after. Then he just stepped toward Kurik, and I knew, OOC that he was dead. It was like this man was real, and his life's work was finally revealing why after all this time my character was sent a way, why I needed Kurik, why I still needed him, but would really never see him again.
Adus had also been played so very, very much like a dumb ape (as he should) that would fail all the Styric, who (sort of) replaced Sephrina, being Little Sister, and more the knights' age. In every other battle with Adus, the enchantments made Adus the fool. Not in Zemoch...nope. They wondered, and even joked, both in and out of character about how I should never ran, and then they realized this was Martel's legacy. It was all set into place...Gods I never smote before and probably never will smite again with a paladin when I killed Adus, forsaking my knight's code and flanking with Talon.
Having said all that, I'm actually not much for Edding take on magic. I dislike it generally. I prefer a higher fantasy in stories. I like to escape into world where more than small magic is possible. Hence why i play systems that allow things just short of time travel, if the story goes on long enough.
The D&D flavor, in general, I like, it's the fluff I don't like. I like D&D more than LotR TBH, there's enough difference that their different species entirely. I love LotR though...well, again, not the books, the movies were enough for me. *shrug* I'm just not a novel person.
Anyway, I thought it was a great quote from Hennet. Usually the quotes they have in other books are quite contrived and forced, leaving them obligatory and disappointingly lack-luster. I dunno, I liked the quote. So when I had a chance to use it as a prop in game, I was glad to.
"The caster wills it, and then speaks to make it happen" doesn't have the same ring...for me.
