Sylvanas: "Time is not a luxury we possess, but I respect your desire to know more. THIS has forever altered the balance of power in Azeroth. Deposits of Azerite are being located across the world, <player>. Though we do not yet understand its full potential, it is clear that this substance has vast destructive capability. What will war look like in twenty years? In a hundred? How can the Horde hope to defend its borders if the Alliance controls the flow of Azerite?"
Sylvanas: "What IS certain is that the Alliance will use Darnassus as a safe harbor for funneling Azerite into the Eastern Kingdoms. Anduin Wrynn will build powerful new weapons, and sooner or later he will turn them upon our homelands. First he will strike at the Undercity and Silvermoon, then his gaze will fall upon Kalimdor. For the sake of the Horde's future, we must be the first to act. By occupying Darnassus, we will control the flow of Azerite and ensure it cannot be used against us. The Alliance will dare not attack its own city for fear of harming civilians. With a single stroke, we will guarantee generations of peace."
Sylvanas: "The kaldorei will defy our occupation... unless we break their sprits. We must inflict a blow that will show them what is at stake. They need to lose something... someone... in whom they have absolute trust and faith. A symbol of hope. <The Dark Lady narrows her eyes.> Malfurion Stormrage must die."
