I love seeing people's characterizations of Nerevar because the fella is so important, but he also functionally isn't a character. He has almost no characterization to speak of. You can pull some tidbits out about how he might of been, but he's basically a plot device--a backstory for all the important people. The only accounts we hear about him are from the most biased and untrustworthy sources in the whole game. So it's so fun to see what people do with those scraps. At this point he's Morrowind fans' collectively owned OC
