"For the Horde!"
"Long live the Alliance!"
Such cries were growing increasingly popular in the game world. Lu Li was already broke within a day and a half of training.
Before the huge event 'Defence of Azeroth: Invasion of the Scourge', there was another event called the Battle of Hillsbrad.
The existence of the Scourge was always present at the Plaguelands. The original king of Lordaeron had already been conquered by the Scourge. Only the Alliance and the Horde managed to resist. Large-scale battles were still yet to begin, but the smaller battles were fairly regular.
Now, the a large, world-based quest for defending Azeroth was released for players to complete.
However, deep-rooted hatred was shared between the Alliance and the Horde. Therefore, an agreement was made where they would have a fight and resolve this conflict.
