That said, they do include a possibly more substantive retcon that has major implications, and that's with Saurfang junior. In the cinematic he gets killed by the LK, but Chronicle's phrasing implies that he died as a result of the plague. That could also just be innocuous, or it could be part of the setup they did with that book as regards the Saurfang vs. Sylvanas conflict. The book does take a few other shots at her earlier characterization, such as muddying her role in allying the blood elves and making her intend to attack Gilneas, which is logistically impossible per Edge of Night.
