World of Warcraft: Legion

Kingdoms Will Burn

The Tomb of Sargeras has been reopened, and the demons of the Burning Legion pour into our world. Their full, terrifying might is fixed on summoning the Dark Titan to Azeroth-and they've already located the key to his return.
With the Alliance and Horde devastated, adventurers must take up legendary artifacts and weapons used by the heroes of old, scour the ancient Broken Isles for relics of the Titans, and challenge the Burning Legion before Azeroth's last hope dies.
Steel yourself, champion. Extinction is imminent.
Following the events of Warlords of Draenor, the alternate Draenor's Gul'dan is expelled by his demonic masters into the original Azeroth with a special purpose - to reopen the Tomb of Sargeras and the gateway to Argus, commencing the third invasion of the Burning Legion, an invasion even greater than the War of the Ancients. Gul'dan also had to find and steal the body of the famous demon hunter Illidan Stormrage.

After the defeat at the Broken Shore, the defenders of Azeroth found themselves exploring the long-forgotten Broken Isles in search of the Pillars of Creation, titan relics which were used to shape the world - and which were Azeroth's only hope for closing the massive demonic portal at the heart of the Tomb. However, the Broken Isles - a land which 10,000 years ago was home to the then mighty night elf civilization - came with their own perils to overcome, from the demon lord Xavius and his satyr armies, to the vrykul's God-King Skovald, to the powerful nightborne night elves, and the deadly naga led by Tidemistress Athissa.

As part of this desperate search, the Kirin Tor, now led by Khadgar, moved the floating city of Dalaran to the shores of this land, with the city serving as a central hub for the efforts of the world's heroes. The death knights of Acherus also took their floating necropolis to the Isles.

To defend their world against the onslaught of the Legion, the heroes of Azeroth sought out legendary artifact weapons to wield in battle, but also found themselves embracing new and unexpected allies in the form of the Illidari, Illidan's elite disciples, freed in desperation by the Wardens that guarded them to fight against the Legion in this hour of need.

Ongoing conflict between the Alliance and the Horde led to the formation of the class orders, with exceptional commanders putting aside faction to lead their classes in the fight against the Legion.

World of Warcraft: Legion ushers in an era of unprecedented conflict for the Alliance and the Horde as the Burning Legion’s crusade against creation enters a terrifying new stage.

In this dire new chapter of the Warcraft saga, the demonic Burning Legion has returned, seeking to call forth their fallen leader—the dark titan Sargeras, Ravager of Worlds. As destruction rains across Azeroth, its heroes must seek salvation among the ruins of the Broken Isles, doomed center of ancient night elf civilization and birthplace of myths dating back to the world’s creation. In the face of hopeless odds, they must learn to master mighty Artifacts—legendary weapons that hold the potential to bring down the corrupted armies of the Legion—and strike an infernal pact with the dreaded Demon Hunters of the Illidari . . . accursed followers of the infamous Illidan the Betrayer.
