Corprus brings madness, but that naturally ends up wearing off, judging by the relative rationality of those ranked Ash Ghoul and above and Yagrum Bagarn. Talking about Bagarn, he appears to be a strange case. Those with Corprus tend to be large and muscular, or extremely puffy. Yagrum is bloated only in the gut, not over half of his body like a Lame Corprus. I assume that this is due to millennia of Corprus mutating him into an extremely unusual case. I also note according to the developer(?) forum posts in the thread "Dwem, little Dwemer of me..." (located here http://www.imperial-library.info/content/sotha-sils-last-words) that Yagrum's memory appears to be clearing after the death of Dagoth Ur. I do not know what consequences this will have. Will all who are infected with Corprus slowly turn back to normal, or will only their minds do so? Can Corprus ever be caught again, now the enchantments on the Heart are gone? I do not know the answers to these questions. So in this thread, people may theorize about the Divine Disease, and the fate of those infected with it.
