Description
Dalaran may appear to be just a floating city, but it is actually our most powerful magical weapon. It will take time to repair the arcane defenses - time the Legion will use to their great advantage.
It is imperative to come up with an interim plan, and quickly!
Archmage Kalec is very knowledgeable about this sort of thing. Perhaps you should consult with him?
