Master of Mutant Design
So you see most of the templates in those books as setting specific?Funny enough, I own two of those.
As for the automatons, I know they are from the Realms but not much more than that. One way to make them more "interesting" is to use the maug grafts from the 3.0 Fiend Folio. In some ways, I wish there was one automaton and they had listed a score or more of attachments to allow them to do specialized work.
