It is a testament to the strength of the TES universe's lore and storytelling in my opinion that learning this actually made me genuinely sad. I know that, lore-wise, the Dunmer may have had it coming. But after all that history, right or wrong, and after having "lived among them" in TES III for so long, I actually, literally, became sad when I read this. (And no, I'm not ashamed to admit that, nor do I think it's strange. It means I can still be emotionally engaged by fiction that I love.)
I am hoping Skyrim gives me enough to love that if it's ever destroyed, I'll feel similarly.
