Half-ogre mage is the term for the theoretical offspring between ogre magi and orcs. Ogre magi were creations of Gul'dan during the Second War, but they refused to mate with orcs for the purpose of creating mok'nathal. Their existence is rare if unlikely.
Like all half-ogres, half-ogre magi speak Low Common and Common. Their ogre progenitors were once part of the Horde, and some learn the languages of other savage creatures. They may also speak Goblin, Orcish, Taur-ahe, and Zandali.
