Blizzard’s creative map design for Khaz Algar has brought Undermine to life as a giant goblin head, as you can see on the new map below.
Undermine is accessed through a new zone, Gutterville, added to the Ringing Deeps near Opportunity Point.
Interestingly, Undermine’s concept dates back to the original game’s development in 1999. Early sketches hinted at its inclusion, proving that Blizzard’s vision for this zone has been brewing for decades.
Finally, here’s the map of Undermine as seen in Patch 11.1.
