The Townlong Steppes is the homeland of the Yaungol. From the Dread Wastes, the Mantid is invading the Shado-Pan’s Niuzao Temple.
The temple has a serious infestation of Mantid insectoids battling the Shado-Pan wardens. At the temple you can see a gigantic black Yak radiating light. It’s named The Black Yak.
Infestation. Mantid insects that look like Roaches on steroids. The Black Yak.
I couldn’t but think of a TV Commercial slogan: “Raid Kills Bugs Dead”.
