Were they really written by the Aedra? Because some of the in game books, people, and Daedra seem to contradict this and I am really not sure anymore. Also I don't believe the Dwemer messed up the heart because the tribunal used it after right? Good point, because the Elder Scrolls tell of all the possible outcomes of any timeline from that point, so it makes sense why Kagrenac would ignore it if other "prophecies" were wrong.
