Having defeated the Horde leader Blackhand, who had stained his honor, Orgrim Doomhammer quickly seized power over the Orc Horde. Now he intends to conquer the rest of Azeroth so that his people can once again find a home on this world. Anduin Lothar, former Champion of Stormwind, left the ruins of his homeland behind and led his people across the Great Sea to the shores of Lordaeron. There, with the support of the noble King Terenas, he creates a powerful Alliance, which other human nations join. But even this may not be enough to stop the Horde's relentless onslaught. Elves, dwarves and trolls also come into conflict as two new forces clash in confrontation. Will the fearless Alliance win, or will the dark tide of the Horde wash away the last vestiges of freedom from the face of Azeroth.
