Standing in Outland as a sanctuary capital shared by both Alliance and Horde, Shattrath City isn't exactly much to look at. The city is divided into several different sections, housing a variety of occupants from draenei to arakkoa to everything in between -- refugees, for the most part. In Warlords of Draenor, we'll finally see Shattrath as it was in its glory days. A coastal city, a museum metropolis, described as an architectural marvel. Unfortunately, the city will also be occupied by the Iron Horde.
The events that turned Shattrath from shining capital of the draenei to the ruins we're familiar with today are steeped in tragedy that still affects the draenei race to this day. Certainly there was sorrow to be found in the fall of the city -- but its fall, and the fall of the other draenei cities scattered around Draenor, were also directly responsible for the evolution of the draenei race as we know it.
