What is Draenor in World of Warcraft

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 opened dimensional portals to find new worlds to conquer, Draenor was torn apart and believed completely lost. However, a large fragment of the world remains, known today as The Outlands.
