A number of facilities are available for characters while in towns and cities. In each major city, characters can access a bank to deposit items, such as treasure or crafted items. Each character has access to personal bank storage with the option to purchase additional storage space using in-game gold. Additionally, guild banks are available for use by members of a guild with restrictions being set by the guild leader. Auction houses are available for players to buy and sell items to others in a similar way to online auction sites such as eBay. Players can use mailboxes, which can be found in almost every town. Mailboxes are used to collect items won at auction, and to send messages, items, and in-game money to other characters.
Tras los eventos narrados en Wrath of the Lich King, Arthas ha muerto, y la guerra en Rasganorte parece haber terminado, ya que la Plaga está controlada por Bolvar Fordragon, convertido en el nuevo Rey Exánime, el carcelero de los malditos. Pero entonces, misteriosos terremotos comienzan a sacudir toda la faz de Azeroth, y poco después, comienzan una serie de ataques elementales contra las capitales de la Alianza y la Horda. Estos ataques son el preludio del resurgimiento del Dragón Aspecto corrupto Alamuerte, que las destruirá, extendiendo su dañino poder por los dos continentes. Cinco años después, en los que se suceden los eventos narrados en la novela World of Warcraft: The Shattering, Ventormenta y Orgrimmar están en proceso de reconstrucción, y la faz del mundo en Azeroth ha cambiado por completo tras los ataques de Alamuerte, que han reducido a cenizas algunas zonas y han provocado violentos maremotos y terremotos que han partido literalmente la tierra en trozos, inundando algunas zonas y haciendo resurgir otras. Alamuerte ha vuelto con un solo objetivo, el de destruir Azeroth, y no se detendrá hasta conseguirlo.
