so my leap is executed, but falls short
aarrrgh
it hurts us, yes it hurtss
So.... ,
The transition to and from, and realization of faerie that seems to be part of the foundation of the theme of the works, does seem (from a human's POV) to be (in part) the study of human nature, and how it relates with mortality. And your premise is that this theme could not be fully reached without a more "noble" form of fairy, (i.e. - one that really didnt exist)? Or, in other words, can one from faerie experience eucatastrophe? The author could not figure out how to describe this without having to invent a new fairie, eh wot?
edit:
Or was it simply that he thought no one would take the stories/legendarium seriously if he used the traditional model - a known commodity?
btw - thanks for the links! interesting stuff
