I want to see him return and bring the Dunmer back to their former glory! Long Live Dark Elves!
Which former glory? The xenophobic racism that encourages slavery of anything not Dunmer? Or the state-supported political infighting, complete with legally recognized and authorized Assassin's Guild? Or the urban culture vs. rural culture politireligion pseudogenocidal mess we got to see on Vvardenfell? Or, going even further back, the Murder-worshiping Padomaic's who, despite having left the Altmer on grounds of religious intolerance and difference in metaphysical opinions, had no issue with sitting their yurt-stakes in the ground and expecting an entire pre-established culture (or two, if we're generous with the Nord's claim to certain areas of modern Morrowind) to make way before them?
Face it: The Dunmer got their wakeup call. And hit the snooze button.
(Lest that come across as overly anti-Dunmer, know that they're easily in my top 3 favorite TES races, through sheer virtue of their awesome. Doesn't mean I can't see the murder-cult forest for the self-destructively racist trees.)
