World of Warcraft (WoW 7.0.1): Legion
World of Warcraft: Legion is the sixth expansion set in the massively multiplayer online role-playing game (MMORPG) World of Warcraft, following Warlords of Draenor. It was announced on August 6, 2015 at Gamescom 2015. The expansion was released on August 30, 2016.
The expansion raises the existing level cap from 100 to 110, features artifact weapons for each class's specializations, includes a new area on Azeroth called the Broken Isles and introduces the demon hunter hero class that starts at level 98. It initially included ten 5-man dungeons and two raids.
Following the defeat of Archimonde at Hellfire Citadel in an alternate timeline Draenor, the orc warlock Gul'dan was transported to the main timeline Azeroth. Gul'dan invaded the Vault of the Wardens, a prison used to contain dangerous beings from across Azeroth, with the help of the traitorous former Watcher Cordana Felsong, whom he had successfully corrupted to his side back on Draenor. In desperation, the wardens released the "Illidari"; demon hunters that use fel power, to help fight against the Burning Legion. Despite this, Gul'dan was successfully able to steal the body of Illidan Stormrage and traveled to the nearby Tomb of Sargeras and opened a massive portal, thereby allowing the Burning Legion to invade Azeroth.
Demonic invasions spawn throughout Azeroth, with both the Alliance and Horde fighting to defend their lands. Khadgar begins researching ways to sever the Legion from their source of power at the Tomb of Sargeras, consulting with the newly awoken Magni Bronzebeard. Magni declares that his innate connection with the land during his slumber has allowed him to communicate with the nascent Titan slumbering within Azeroth. Only by using the five Pillars of Creation, incredibly powerful Titan artifacts, can the forces of Azeroth drive back the Legion. Khadgar teleports the Kirin Tor capital city of Dalaran to the tower of Karahzan to further his research.
Faced with an increasing number of demonic attacks, the Alliance, Horde, and Argent Crusade prepare to launch an invasion with naval, air, and ground forces to the Tomb of Sargeras on the Broken Isles. The demons mislead the Alliance and Horde as to the size of the demonic army present at the Tomb, manipulating them into far underestimating the size of the demonic host. Although they make initial headway against the demons, the heroes of Azeroth are unable to prevail: the majority of the Argent Crusade is destroyed before the Horde and Alliance arrive, and both factions lose their primary leaders in the process. Anduin Wrynn becomes king in his father's place, and Vol'jin's last command is for Sylvanas to lead the Horde. Even worse, miscommunication leads to many within the Alliance believing that the Horde intentionally abandoned them during the battle, inflaming tensions between the two factions to the boiling point once again.
With both the Alliance and Horde devastated by the battle at the Broken Shore, a new source of power is required to defeat the Legion. The players—including the newly introduced demon hunters—must acquire and master artifact weapons and find the Pillars of Creation that hold the power to stop the Legion's invasion. While the Legion remains a focus of the Broken Isles as a whole, it only takes center stage in one (Stormheim). In the other three, primary opposition comes from the Naga of Azshara (in Azsuna), the Old Gods and the Emerald Nightmare (in Val'sharah), and a race of subterranean rock-creatures called Drogbar (in Highmountain).
After locating the first four Pillars, the heroes receive a distress call from exiled Nightborne from Suramar, where Gul'dan has besieged their home and seized control. With the help of both Horde and Alliance, the players liberate the Nightborne and their home, kill Gul'dan, claim the last Pillar of Creation, and restore Illidan to life. With his assistance, the class hall orders establish a foothold on the Broken Shore while facing heavy resistance. After fighting back the invasion forces, the players enter the Tomb of Sargeras to end the Legion's presence on Azeroth. The players find and kill Kil'jaeden, but Illidan uses the opportunity to open a rift between Argus and Azeroth, setting the stage for the players to invade Argus. Meanwhile, Anduin Wrynn, plagued with doubt regarding his ability to be a worthy successor to his father, reclaims Varian's compass with the help of Alliance champions. Venturing to the entrance of the Tomb, where Varian fell, Anduin recovers Varian's sword Shalamayne and, with the help of Genn, Velen and even Varian's spirit, finds within himself the confidence and determination to serve the Alliance as its High King.
Velen summons the Alliance and Horde to travel aboard The Vindicaar. The players travel to the surface and quickly meet the Krokuun, the surviving Broken Draenei that were left on Argus. Shortly thereafter, they encounter the surviving members of the Army of the Light, including Turalyon and Alleria. The player gains ground on Argus and rescues the dormant prime Naaru, Xe'ra. However, she is destroyed by Illidan after she attempts to remake him as her prophesied chosen one. Magni arrives and is able to communicate with the world soul of Argus: through it, he learns that Sargeras has captured the essences of his fellow titans, and seeks to revive them under his control.
The players invade Antorus and free the remaining Titans, who in turn force the world soul of Argus to manifest. Thoroughly corrupted and suffering, the players are forced to kill it. The players see that Sargeras is at Azeroth and prepared to take it for himself. Sargeras is pulled away by the Titans, but he hurls his sword into Azeroth as a final act of spite. The players return home, with Illidan staying behind to face Sargeras inside his prison.
While Sargeras is defeated, his giant sword remains; players absorb its corrupting poison into their artifacts, which greatly weakens them but buys the world of Azeroth time. However, the titan's blood has been erupting to the surface in the form of a crystalline substance called Azerite, which has tremendous magical potential. Both factions, still honoring their heroes and mourning their dead, are unwilling to let the other faction have sole access to this miracle substance, and prepare for war again...
