Tell him sorry but no. Homer, Virgil, and Milton all did it in 12. Big Dave don't break no rules. (Actually a "Beldin" book would encourage a "Silk" book, followed by "Barak," "Mandorallen," "Hettar," "Sadi," "Zakath," "Urvon," "Cyradis," ad nauseam.) Big Dave ain't gonna write "Garion and the Ant People" ("Aunt people?") or "Abbot and Costello Meet Zandramas." This is called "drooling." I slobber sometimes, but I never drool.
The tough thing about writing is knowing when to quit. The Elenium/Tamuli story is finished, and I'm not going to dribble off into "Talen and Berit meet Frankenstein." I'm far too fond of the characters to insult them with that. This is one of the great dangers we find in success. The writer and publisher are lured by the chance to take one more trip to the bank (in the same way that movie producers are). The fact that you wanted more is a fair indication that we hung it up at just the right time. The next logical step would probably have been, "Another Sparhawk story? Oh, God, can't he find something else?"
Besides, Aphrael would turn me into a toad if I tried another one. She doesn't want to be grown up.
Well, now, Polgara is finally out there, and I'm fairly sure that some of you have even read it by now.
I'm also fairly sure that several of you have spotted some variations, and you're just dying to smugly point them out to me. Don't bother. Those letters tend to get lost for some peculiar reason. And may I draw your attention to page 15? I asked Pol to cover my tail-feathers, and I think she did it rather well. Ten witnesses to any event will each see it differently and will each tell a different story. Trial lawyers absolutely hate that.
Anyway, now you've got the whole story - and I do mean that's all there is and all there's going to be. There won't be any more Garion stories (or Sparhawk stories either). An open-ended story is an invitation to droll off into pure junk, and I respect both Garion and Sparhawk too much to do that to them. (Silk invents a spaceship and goes to Mars? Sparhawk meets James Bond? Hettar shoots it out with Roy Rogers at the O.K. Corral?)
No, I don't think so. Let's not ride a good horse to death.
My now publicly exposed co-conspirator and I are currently examining an entire new world. (Creating worlds is a real fun hobby.) We'll have new characters and a new quest. The good guys will probably win - unless things don't turn out well.
It all sorta boils down to the fact that we're moving on into unexplored territory, and that's half the fun. We will have fun with it, because when this stops being fun, we ain't a-gonna do it no more.

My current excursion into fantasy has given me an opportunity to test my technical theories [of writing]. I made a world that never was, with an unlikely theology splattered against an improbable geology. My magic is at best a kind of pragmatic cop-out. Many of my explanations of how magic is supposed to work are absurdities - but my characters all accept these explanations as if there was no possibility of quibbling about them, and if the characters believe, then the readers seem also to believe.
