World of Warcraft: Birth of the Horde

Although the young leader Thrall has put an end to the demon's curse that has stained his people for many generations, the orcs still struggle to overcome the sins of their bloody past. As a fierce Horde, they waged several devastating wars against their ancient enemy—the Alliance. The rage and bloodthirstiness that drove the orcs to destroy everything in their path nearly consumed them.
For a long time, the noble orc clans lived in relative peace with their mysterious neighbors, the draenei, on the idyllic Draenor. However, the vile emissaries of the Burning Legion had other plans for these two unsuspecting races. The demonic lord Kil'jaeden set in motion a grim chain of events that not only led to the extermination of the draenei but also transformed the orc clans into a single unstoppable machine of hatred and destruction.
