Main Heroes And Villains involved

Maiev Shadowsong

If the Watchers are infamous among the night elves, Maiev Shadowsong is a legend. Famed for her uncanny ability to capture any enemy, Maiev tracked Illidan Stormrage, the Betrayer, all the way to the Black Temple in Outland. After his demise, she imprisoned his surviving followers, the Illidari, vowing never to allow the fel-touched demon hunters to roam free ever again.

Xavius

Xavius once terrorized Azeroth with an affliction that almost obliterated the walls between reality and dream. His machinations ended in defeat, but he has been given another chance at vengeance. Now, Xavius leads the conquest of Val'sharah, where the tainted World Tree Shaladrassil spreads the Emerald Nightmare's corruption. With an army of vile satyrs at his command, Xavius will stop at nothing to vanquish all who oppose the Burning Legion.

Anduin Wrynn

Heir to the throne of Stormwind, Anduin is wise beyond his years. Time and again, he has used diplomacy to end conflict, inspiring even his warrior father to lay down arms in pursuit of peace. But diplomacy has its limits, and some villains can't be reasoned with. As the Burning Legion threatens to annihilate Azeroth, Anduin will learn the true cost of peace… and whether he's willing to pay it.

Tidemistress Athissa

Queen Azshara, former leader of the ancient night elves, rules the naga with supreme authority. Her servants are many, but few can match the fanatical devotion of Athissa. At her queen's command, she is poised to lead a massive naga army into Azsuna, a region rumored to hold a long-lost titan relic of power. Nothing will stand between Athissa and this prize—not the cursed night elf spirits who haunt the land nor the Horde and Alliance forces that are gathering on the Broken Isles.

Genn Greymane

In recent years, the grizzled ruler of Gilneas has suffered many hardships: his son and his nation fell to the Banshee Queen Sylvanas and her Forsaken, and he nearly lost his humanity to the worgen curse. Yet from these tragedies, Genn has found new strength and courage. He is determined to fight tooth and claw against any enemy that threatens the safety of the Alliance.

Dargrul the Underking

For centuries, the tauren and the drogbar tribes of Highmountain lived in peace. But soon after the Legion's arrival, a drogbar leader named Dargrul the Underking destroyed their unity and stole the Hammer of Khaz'goroth, a powerful artifact protected by the Highmountain tauren. Using the terrible power of the Hammer, the Underking intends to take control of Highmountain.

Khadgar

Though he was unable to stop Gul'dan from opening the Tomb of Sargeras, allowing the Legion to flood into Azeroth once more, Khadgar is determined to find the means to reseal the portal and foil the Legion's invasion. He knows that the combined forces of the greatest champions of Azeroth are necessary to succeed, even as dissenting voices speak against a coalition and risk ultimate destruction by the demons.

Gul'dan

Gul'dan owes allegiance to no one save his Burning Legion masters. On Draenor, the power-hungry orc warlock nearly had his entire race enslaved to demons. Though his plans failed, Gul'dan survived. Under the Legion’s command, he was banished to Azeroth to open a gateway for a monstrous invasion force unlike anything the Horde and the Alliance have ever faced.

Sylvanas Windrunner

The Forsaken's ruthless leader is a formidable champion of her people. But with the Burning Legion's invasion, the stakes for the Dark Lady have never been higher. Should Sylvanas perish, her demise will be the beginning of her eternal damnation. All that stand between her and this doom are her Val'kyr, yet few of these spirit guardians remain. As her fate edges closer to the abyss, Sylvanas must decide how far she'll go to protect her people… and whether they're more precious to her than her soul. 

Illidan Stormrage

After the fall of the Black Temple, the corpse of the lord of Outland, Illidan Stormrage, disappeared. No one knows the true fate of Illidan's remains, but legend holds that Warden Maiev Shadowsong took his broken body to the Vault of the Wardens so that Illidan's dark, lingering soul could suffer the rest of his eternal sentence—along with his followers, the feared Illidari. Justice to be forever served…
