Yes, there is a great amount of useful lore information in this here thread. But as I understand it, every society is going to have individuals/groups whose lifestyle or evolved philosophy is going to cause a break with societal norms. Yes, the vast majority of the nameless collective is going to be easily summarized by historical events and the categorization of their order/group/caste, but to say that certain Kaldorei cannot be "humanized" or "secularized" is really unaccomodating to RPers who want to a play an elf off the beaten track....
Your point is well-made, but you fail to realize the biggest thing about night elven lore. I hate to draw this distinction all the time, but the Night elves rely on conformity in much the same manner as the Japanese. They are all very bound to tradition and following the set societal rules from day one of their incredibly long lives. 'Different' to them means wearing a different shirt color, not anything so horrifyingly, radically different as ignoring your sense of smell.
...That does bring up an interesting point, though. The Japanese, while based on so many strict rules (Even in language, which I remind everyone is NOT appropriate to use IC in any other manner than general structure), they also manage to lead the forefront of the word 'wierdness'.
Anyway, more to the point, I've heard the 'well maybe I'm different' excuse from purple humans more times than I can count. I have yet to see more Kaldorei that
don't break societal norms than those that are 'different'.
