At the start of 4.0 all of the entrances towards the (at the time) endgame instances were located in this area. Throughout later patches these entrances were gradually relocated to other maps, greatly diminishing the role of and activity on this map. In the 4.8 patch this area was recycled into a (bonus) PvE farming area for level 65+ characters. Shortly after however the valuable drops from this region were secretly removed from the loot tables, supposedly to combat gold bots which had found their way into the region. The area now lies abandoned.
