[Ivriniel]

Eowyn struck somewhere else--with a non-magical weapon (significant. Would her blade have done anything, without Merry's first blow. And what of the numbing of their arms after striking him? Some 'energy' or something was removed from their bodies?

And her gender, being a woman, was also somehow significant. I've always thought that. Some artefact of Sauronic influence was implicated by way of lessening or something because of her gender. Perhaps female stature and bearing had some implication for the Nazgul's history that evoked--shame--or --doubt-- or even --fear-- or possibly even 'thank friggin god, am I sick of one eye or what. I'm dunnin--yay--get on with it wench'. I imagine the Nazgul in life perpetrated sexual depravities and violences, such as taking concubines after conquests. This was part of Tolkien's mythology, as we saw with Maeglin who was subverted in the end by Melkor this way in lust for Turgon's daughter. But, on another point, I do not understand the prophesy that Glorfindel spoke of about the Witchking.

So, for Eowyn, and the Nazgul 'wyrd', I wonder then if the severing of Spell binding Will to body together with the doubt of sudden fear and shame exposed a fundamental rift in metaphysical dimensions allowing a normal blade to finish him off. Perhaps enough of 'him' came back for a short moment, and -- pow -- he copped it.

This theme of shame and critical strikes during battle, felling the other--if anyone remembers, I think it was Fingon singing in Tol Sirion in contest with Sauron, and during the Song, the critical vulnerability achieved to weaken Fingon by the verse about the Kinslaying. That was when Fingon buckled--when Sauron weakened Fingon with the naming of the shame of the kinslaying. Fingon's Will (there's that word again) faltered because of shame.
