I agree with you about Uldor. Even as a tender newby Silm writer working on AMC, that single moment really defined how I developed his character. It is impossible for me to reconcile a character capable of that act--to say nothing of kinslaying three times, acting as regent for the Noldor in Beleriand, holding Maglor's Gap, and bearing the Silmaril to the sea when the pain of that drove his brother to suicide--with the doe-eyed wimp with hands suited to a harp and not a sword that appears in many fanfics.

I can say, too, that fandom itself is perhaps proof of how artistic/creative types tend not to be particularly meek or passive, else we wouldn't fight so bitterly at times over things both silly and serious. ;)
