I have a copy of this I picked up in a used book store. The first few pages of the book as well as the back cover, all reference a compact disc to be used while reading the book. I didn't get a copy of this CD with the book.
Does anyone have a copy of the sound files from this disc? Does anyone know where I can find these files online?
Thanks Wicke!
You're most welcome!
To be honest, I was kinda surprised to find that available on the wizard's website.
Yeah, that CD is awesome! 
Oh I love that book. I think 4shared.com has that on their files you can download for free.
If you start to feel your head is about to explode, that's probably the sheer power of my envy for you. Seriously, I wish I could just run into a random used books store and find Planescape books...or hell any kind of RPG book.
He he he!
I just went home to TN. In Knoxville there is a used book, music and movie store. It is the size of your average Wal-mart. I hit the mother load!
I've been trying to complete my hardback collection of Drizzt books (I know, but I do like the stories). I managed to find 8 of them! $3, $4, $4, $5, $5, $7, $8, $8 for books that range from $27 to $35 new. I also managed to find the Legend of the Seeker Season 1 and 2 DVD's, a couple of adventures, three copies of the Star Wars D6 second edition handbook, and some cool graphic novels.
It. Was. Totally! Wicked!

How is Legend of the Seeker?
Call me a cheeseball, but I really liked that show. It was very campy (not quite so much as a Hercules or Xena, but close). It's not really serious fantasy (whatever that might mean), so my wife was able to watch and enjoy it with me. Also the actresses that played the Mother Confessor and Cara weren't too hard on the eyes if you know what I mean.
If you're expecting a non-corny, faithful adaptation of the books, don't watch it - you'll only be disappointed.
You can download them from here:
