I have a query -- is it possible that Rich's "fine line" comment might be interpreted as authorial spin? For instance, we pretty clearly have "vampires" (which somebody else invented) and "vampires as used in OOTS," which is Rich's. That *could* be an admonition for us not to get too technical (except for fun) while we try to guess, and maybe instead simply to focus on what best fits the big iconic scenes as we get the list of "things that this dude could be."

(I still think "my Daddy's a big eater" has got to be a hugenormous hint, but darned if I can really come up with anything beyond my already-shot-down which fits the bill).
