↑ El nombre de estas dos facciones tiene su origen en Warcraft II: Mareas de oscuridad. La Alianza es la facción de los humanos, fue creada en el preludio después del éxodo de Anduin Lothar y los demás supervivientes humanos del reino de Ventormenta, cuando las hordas orcas eran imparables y estaban fortalecidas por otras criaturas como troles, ogros, goblins y dragones.
World of Warcraft is set in the same universe as the Warcraft series of real-time strategy games and has a similar art direction. World of Warcraft contains elements from fantasy, steampunk, and science fiction: such as gryphons, dragons, and elves; steam-powered automata; zombies, werewolves, and other horror monsters; as well as time travel, spaceships, and alien worlds.
Deep within Blackrock Mountain, the black dragon Nefarian conducted twisted experiments with the blood of other dragonflights. Intent on seizing the entire area for his own, he recruited the remaining Dark Horde, a rogue army that embraced the demonic bloodlust of the old Horde. These corrupt orcs, trolls, and other races battled against Ragnaros and the Dark Iron dwarves for control of the mountain. Nefarian created the twisted chromatic dragons and a legion of other aberrations in his bid to form an army powerful enough to control Azeroth and continue the legacy of his infamous father, Deathwing the Destroyer. Nefarian was vanquished by the heroes from the Horde and the Alliance.
World of Warcraft takes place in a 3D representation of the Warcraft universe that players can interact with through their characters. The game world initially consisted of the two continents in Azeroth: Kalimdor and the Eastern Kingdoms. Four separate expansions later added to the game's playable area the realms of Outland and Draenor and the continents of Northrend and Pandaria. As a player explores new locations, different routes and means of transportation become available. Players can access "flight masters" in newly discovered locations to fly to previously discovered locations in other parts of the world. Players can also use boats, zeppelins, or portals to move from one continent to another. Although the game world remains relatively similar from day to day, seasonal events reflecting real world events, such as Halloween, Christmas, Children's Week, Easter, and Midsummer have been represented in the game world. Locations also have variable weather including, among other things, rain, snow, and dust storms.
Seven expansions have been released: The Burning Crusade, released in January 2007; Wrath of the Lich King, released in November 2008; Cataclysm, released in December 2010; Mists of Pandaria, released in September 2012; Warlords of Draenor, released in November 2014; Legion, released in August 2016; and Battle for Azeroth, released in August 2018. Players are not required to purchase expansions in order to continue playing; however, new content and features such as higher level caps and new areas may not be available until they do so.
