My formost description for the exterior is the impression Vlad has at his very first arrival. Taltos paperback page 18 thru 20. I've never played DnD so I can't say I've ever seen the style castles you're talking about. I simply assumed since he desided to make the castle fly about half way thru building it ( dammit I cant find the page now but I'm nearly positive its in Lord of castle black) there would only be castle there, nothing stuck to the bottom that would indicate it had started on the ground.
