* Where did Dr. Prunesquallor go to medical school?
* Where did the seventy-seven earls' wives come from? Are they from noble families from outside Gormenghast? Commoners from within Gormenghast? Or is there incest (which would explain a lot, actually)?
** I've been wondering about the Countess and her precedessors - the book explicitly states that she isn't one of the Groans or the commoners, which means that she must come from the outside world.
*** There's probably some limited contact with the outside for marriages and such, but its tightly controlled and kept away from the average person(if there is such a thing in Gormenghast).
