Heh, that is just last season with the Reapers. We are still discovering things and if you play a Dark Elf, you could end up helping shape some of that. I know some adventurers have made contact with the Dark Elves. Most kingdoms/races are become focused solely on themselves and protecting their own. There is a lot of new information and no race really knows or trusts the other right now.
Chris (who posted above and is not Chris Thetford, but an awesome guy none the less) posted very valuable advice. A character history should be more about shaping your views, personality, and provide a sense of character. (Which also sounds like your on the right direction).
Again, having an event this weekend. Should come check it out.
