The use of the New Plague on humans has thus far been only partially successful. While it kills the victim, it doesn't bring the human back after death as a new Forsaken. Other problems remaining include distribution; the Royal Apothecary Society is searching for a way to effectively spread their new plague, so that no living thing remains on the entire planet...leaving all of Azeroth as one big plagueland, ruled by the Forsaken. Sylvanas' initial plan is to wipe out her immediate enemies — the Scourge and then the Alliance, and raise them again to her cause.
