Zeroth is dying. The Horde and the Alliance defeated the demonic Burning Legion, but a dire catastrophe is unfolding deep below the surface of the world. There is a mortal wound in the heart of Azeroth, struck by the sword of the fallen titan Sargeras in a final act of cruelty. For Anduin Wrynn, king of Stormwind, and Sylvanas Windrunner, the warchief of the Horde and queen of the Forsaken, there is little time to rebuild what remains, and even less to mourn what was lost. Azeroth's devastating wound has revealed a mysterious material known as Azerite. In the right hands, this strange golden substance is capable of incredible feats of creation. In the wrong ones, it could bring forth unthinkable destruction. As Alliance and Horde forces race to uncover the secrets of Azerite and heal the wounded world, Anduin enacts a desperate plan aimed at forging a lasting peace between the factions. Azerite jeopardizes the balance fo power, and so Anduin must gain the trust of Sylvanas. But the Dark Lady ever has her own machinations. For peace to be possible, generations of bloodshed and hatred must be put to rest. But there are truths that neither side is willing to accept and amitions they are loath to relinquish. As Alliance and Horde alike grasp for Azerite's power, their simmering conflict threatens to reignite all-out war -- a war that would spell doom for Azeroth.
