This mission is available after finding Secret Level in Dalaran. It is a famous tower defense game. The blood elves must pass trough the portal, and the portal must be defended from the coming waves of monsters with towers placed on their way. The portal have some health and can stand a few misses. More advanced and powerful towers will be available in time. The two heroes Kael and Lady can also move around and help. The creature waves do not attack the heroes. A lot of air attack towers will be needed to win this game. 4 workers should be enough to build more towers on 4 different places after every wave. In the end, almost the whole way should be covered with towers to stand this menace. Winning will give the Panda hero in next mission.
