Y'know, I think the real villain of the piece doesn't even appear in it: the great-aunt. Umi's grandmother is desperate possibly to the point of mental impairment, and Nax was basically defending his turf. Whereas the great-aunt (whose name I can't seem to find) took advantage of M'belyyn'da's desperation and whatever leverage she used on her family to set up this wedding, probably for some sort of political advantage.

Pretty typical really.
