I think I'm onto something with the fourth one: the fourth one MUST deal with the Sea of Ghosts. In http://www.imperial-library.info/mwbooks/lessons.shtml#15 of the 36 Lessons when the Sharmat speaks, he says he brings "AN ANCIENT SEA" and refers to Morrowind's Dark Elf population as "BLIND FISH" and basically tells them to swim in the new fire, and since I literally just read that as I type this sentence, I havent' figured it out yet.
Much discussion would do me veeeery good at this point, ladies and gents.
edit: provided another link because I'm an inconsiderate piece of crap.
