Upper Kingdom
From WoWWiki
The Upper Kingdom is one of the sections of Azjol-Nerub, the other being the Old Kingdom (and subsection Inner Kingdom). Controlled mainly by the undead, with a small section under the control of dwarves, Doorward.
This area includes more recent structures that were built when the nerubians grew too numerous to stay below. The War of the Spider was fought through here, so much of this area is destroyed. The Scourge now occupies this level; they've reopened damaged passages and cleared rubble-filled tunnels, but they did not bother to repair the many statues, friezes, and murals that were ruined.[1]
History
On the surface of Upper Kingdom[2], of the shattered kingdom of Azjol-Nerub, pillars of ice pierce the land like the teeth of an enormous beast. Perhaps it was wise that heroes recruited an ally from the native inhabitants.[citation needed] When Arthas entered the Upper Kingdom, he faced collapses caused by unexpected quakes and had to get beyond various nerubian traps while Anub'arak managed to get through by tunneling.[3]
