Many years after the Dark Portal that bound the Orcish homeland of
Draenor and the Human world of Azeroth was destroyed, a young Orc
named Thrall was captured and raised as a slave by humans who followed
the ways of treachery rather than those of honor. 

Using the skills driven into him by his captors with his own natural strength
and courage, Thrall escaped his wicked masters and, once free, set out to
find his stolen heritage. Finding his kind forced to live passively in controlled
settlements, the young warrior sought out the few, scattered Orc clans
that managed to evade the wrath of the Alliance. From their camps in the
harsh wilderness, Thrall swore to lead his brothers back to the status their
heritage demanded. Under Thrall's leadership as the new Warchief of the
Horde, the Orcs rediscover their abandoned Shamanistic culture and use
this newfound power to revolt against their cruel wardens. 

As civil strife rages through the nations of the Alliance, the lands of Azeroth
undergo strange changes, and the threat of a new, unseen foe draws near.
Finally, in an unholy firestorm from the heavens, the Burning Legion arrives.
Cursed to roam the greater realms forever to consume the primal energies
of magic to survive, the Legion has ravished world after world in its mad
lust for arcane power. Cunning, sinister and seemingly unstoppable, these
dark slayers come to not only drain this domain of its magic, but to
eradicate all life within it, as well. 

Now, in the face of an even greater invasion, the reunited Horde and the
armies of Azeroth have shifted their focus from conquest, betrayal, defense
or honor to that of basic survival.
