The Burning Crusade
Several years have passed since the Burning Legion's defeat at the Battle of Mount Hyjal - and the races of Azeroth have continued to rebuild their once shattered kingdoms. With renewed strength, the heroes of the Horde and Alliance have begun to explore the broken lands beyond the Dark Portal. What dangers or rewards await mortal champions in Draenor? And what will the Alliance and Horde do when they discover that the demons they thought vanquished have returned to renew their terrible Burning Crusade?

This will only work for the player, pet, party members and pets, and raid members and pets. You can use "-target" or "-pet" to indicate the target or pet of the named unit, e.g. /cast [target=Desmondia-target,harm] Shadow Word: Pain
