The blasted world of Draenor tears itself apart. The Alliance grows uneasy as the Orcish internment camps are reopened. Only a few, scattered Orc clans evade the Alliance's wrath and eke out a living in the harsh wilderness. Thrall, a young Orc raised as a Human slave and gladiator, escapes from bondage and sets off on a quest to discover his stolen heritage. Thrall succeeds in reuniting a number of renegade Orc clans and leads them in revolt against the Alliance Regional Wardens.
Tensions run high amongst the Human leaders.
Thrall becomes the new Warchief of the Horde and helps to reintroduce his people to their abandoned shamanistic culture. The reinvigorated Horde finally begins to lose the last traces of the Legion's demonic corruption.
