They did have a couple of questions, and I thought I'd just cover them here real quick (I'll also send an email, in case they don't read this). (Caution: Spoilers! - actually there are spoilers throughout the podcast too, so don't listen if you think you're going to play in the adventure.)
- I'm pretty sure the grey monks are original, and not found in Gygax's dungeon. I don't recall hearing about them...
- The gate to Lewis Carroll's Wonderland is in the mushroom forest in the Greater Caverns.
- Unfortunately the three books can't be bundled on DriveThruRPG/RPGNow because of a technical limitation of the site. You can't do bundles of print books, so you have to add them separately to your cart. The pricing for the books was adjusted so that the total is what it would have been if I had been able to do a print bundle.
- The maps were printed in their own book based on playtest feedback. It's *far* easier to have a separate book rather than needing to flip back-and-forth in one larger book. I found that out myself, too, running it for my group at home as well as at conventions. When the decision was made to do an illustration book (because the fans overwhelmingly said that was something they'd like to see), it made sense to treat it the same way.
- You're correct about the designer's notes that were in the original free version - they were excised because, as a published product under the OGL, I was much more sensitive to copyright issues. I might do some designer's notes here on the blog, if people think it would be fun and/or helpful. Let me know!
