Destruction rains down upon Azeroth. Demons of the Burning Legion surge into our realm, heralding the return of the dark titan Sargeras, Ravager of Worlds. As doom comes for the Alliance and the Horde, Azeroth’s 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. There, they’ll harness legendary and forbidden powers to hunt unspeakable nightmares and unstoppable fel armies—and save their world from falling under an endless burning shadow.

In the face of hopeless odds, Azeroth’s champions must summon the strength to wield fabled Artifacts, powerful weapons of lore that hold the potential to bring down the Legion. They’ll also strike an infernal pact with the Demon Hunters of the Illidari, an ancient elven order of fel-tainted assassins . . . and accursed followers of the infamous Illidan the Betrayer.

World of Warcraft: Legion sends players on a forbidden journey to the ruins of the Broken Isles in search of the mythic Pillars of Creation—powerful titan relics said to have shaped Azeroth, and last hope for the world’s salvation. Once the magnificent seat of an ancient night elf civilization, the Broken Isles are now haunted by twisted elven aberrations, horrors from the Emerald Nightmare, and other grim remnants of legends long forgotten. Among the Isles, players will face the armies of the Legion and other dark forces across an array of all-new zones, dungeons, raids, and more on the way to the new level cap of 110.

With the Horde and the Alliance in disarray, players must seek out and bring together other like-minded champions to stand against the demonic hordes. In Legion, each player will take charge of an Order Hall—a site of great power linked closely to a character’s class and cause. The Order Hall will serve as each hero’s base of operations—and a bastion of hope—during their journey to the Broken Isles. From there, players will send NPC followers on missions to help defend Azeroth from the demonic incursion . . . and forge their Artifact into a Legion-felling force to be reckoned with.

Blizzard announced that players have forged a truly formidable defensive front—as of the expansion's first full day of launch on August 30, more than 3.3 million copies of Legion had sold through, matching the all-time record achieved by previous expansions and making it one of the fastest-selling PC games ever. In addition, World of Warcraft's launch-week player concurrency climbed to its highest point since the 2010 launch of the Cataclysmexpansion, as champions from around the world united to strike a mighty first blow against the fel invaders. But the battle has only just begun.

"It's been a thrill to see players hunting demons, powering up Artifacts, and freely exploring all the new zones in Legion," said Mike Morhaime, CEO and cofounder of Blizzard Entertainment. "We worked hard to make this the best World of Warcraft expansion yet, and we look forward to providing players with even more content as Legion's epic story unfolds in the months ahead."

While players are currently entrenched against the first wave of demonic invaders, Legion's next exciting chapter is already in the works. Last weekend at PAX West, Blizzard unveiled new details on theexpansion's upcoming first major content update, Patch 7.1: Return to Karazhan, featuring a reimagined version of one of World of Warcraft's most popular raids. Players will explore a sprawling five-player Mythic dungeon, facing familiar foes from Karazhan's past—and encountering plenty of surprises and twists along the way. The update also features a new set of quests unfolding over multiple weeks in the fallen night elf city of Suramar, as well as a brand-new raid: the Trial of Valor, which sends players deep into the vrykul underworld of Helheim.

For those seeking glory in Arenas and Battlegrounds, Legion also features a new Honor system that provides an entirely new PvP progression path. As players dominate the enemy faction, they’ll unlock PvP-specific spells and abilities that open up a range of new tactical possibilities, and earn prestigious new titles and rewards.

To help the heroes of Azeroth prepare for the coming invasion, World of Warcraft: Legion will allow players to boost one character to level 100, including a newly created character, quickly getting them primed and ready to battle the Burning Legion alongside their friends.

The expansion is loaded with features and content that will transform players into Azeroth’s elite vanguard against the shadow, including:

• Turn the tainted power of the Legion against them as an all-new hero class—the vengeful Demon Hunter. As a damage dealer or tank, pursue and evade your targets with preternatural agility; draw upon your demonic fury to fuel devastating attacks; and strike fear into your foes by metamorphosing into hellish new forms.
•  Build a battle-forged bond with your own Artifact—a legendary class-specific weapon that transforms and grows in power as you battle the Legion. Customize your Artifact with personalized traits, tempering—or twisting—it into a form that suits your character.
• Seek your world’s salvation among the forbidden ruins of the Broken Isles—mythic seat of night elf civilization, gateway to the Emerald Nightmare, and hiding place of the titan relics used to shape Azeroth.
• Find refuge from the felstorm at your Order Hall, a site of great power linked closely to your character’s class and cause. Whether you follow the code of the paladin or the dark ways of the warlock, unite fellow members of your order to carry out class-specific missions and defend against annihilation.
• Prepare to face the invading armies of the Legion with a level-100 character boost, and experience this night-shrouded new chapter of World of Warcraft alongside your friends.
• Dominate the enemy faction in Battlegrounds and Arenas to progress through the all-new Honor system. Unlock PvP-specific spells and abilities that open up a range of new tactical possibilities, and earn prestigious titles and rewards.
• . . . And More: Take on a wide array of Dungeons, Raids, Battlegrounds, Challenge Modes, and more on the way to the new level cap of 110—no matter what kind of adventures you seek, endless possibilities await.
