Portal (WoW)  

Portals are mystical gateways that are either opened by a friendly mage or are already open as is the The Dark Portal. A mystical doorway to Outlands. Portals are a mages best friend, having the ability to move players to all the major cities within their faction and Shattrath. Mages learn the art of opening portals at level 40 when they have already mastered enough of the arcane arts to control such unstable power. But one must treat lightly for there are mages who open various portals to mislead the young traveler to lands they are not ready to face.
