Warlords of Draenor is likely to be the next World of Warcraft expansion after a trademark for the title was successfully registered by Blizzard.
This follows last month's registration of the Warlords of Draenor domain.
It's believed the expansion will be prominently featured during the BlizzCon 2013 opening ceremony on Friday.
According to WoWWiki "Draenor was the homeworld of the orcish race and the last refuge of the draenei before their arrival on Azeroth.
"When the orc shaman Ner'zhul recklessly opened dimensional portals to find new worlds to conquer, Draenor was torn apart and believed completely lost. However, a large fragment of the world remained intact. That fragment is known today as Outland."
