The entire Peninsula was ravaged by brutal combat when Khadgar, the new leader of the mages of the Empire successfully reopened the portal after three years when before, Medivh had managed to seal it. Utilizing the vast powers of the Ley Lines in Azeroth, Khadgar had managed to puncture a hole in the fabric of space that separated Azeroth from Draenor. The Emperor had prepared for this and had massed a massive force of troops and supplies at the gateway awaiting for the moment of the reopening of the portal for additional conquests.
