The map of Draenor is captured by me from the wow art panel today.
By the map we can see there is a montain, The Chronal Spire, where may connect the Draenor to the present Azeroth.
Also, we can see Blackrock clan and Shattered Hand clan belonged to Iron Horde.
Because this is a new account, I cannot link the images. I am sorry for that.
Please someone helps me to link the images.
P.S I updated the map
