Yomin, is this from one of the novels, or is this a creative analysis you developed? There are some seemingly contrary points in there, according to the novels (although, we all know how it is with SW: nothing has any real continuity). The account of the destruction of Yuuzhan'tar is not what I have seen in the novels to this point. Also, there's been some real and serious (OK, and admittedly joking) speculation as to the beginnings of the YV as a species. Some of it is quite interesting and well-reasoned, too. If you're up to it, look here: How do the Vong reproduce?
