World of Warcraft: Warlords of Draenor is the fifth expansion to the massively multiplayer online role-playing game World of Warcraft. It was announced on November 8, 2013, by Chris Metzen at BlizzCon 2013. The expansion will raise the existing level cap from 90 to 100 and will introduce player-built, upgradeable garrisons.
The expansion is set after the events of World of Warcraft: Mists of Pandaria and takes place on the world of Draenor, the original homeworld of the orcs, prior to its destruction and the creation of Outland as featured in Warcraft II: Beyond the Dark Portal, Warcraft III: The Frozen Throne, and World of Warcraft: The Burning Crusade. Legendary characters of Warcraft's past, such as Grom Hellscream, Ner'zhul and Blackhand, will appear.
