After Lei Shen and Rend signed the armistice treaty, the Mogu army that had been attacking the Shado-Pan Garrison in the Townlong Steppes withdrew without the slightest hesitation. They showed no attachment even to the Temple of Niuzao, which they had occupied. The Shado-Pan smoothly retook the temple and freed Niuzao, who had been imprisoned by Shan Bu's dark magic.
The Son of Heaven kept his word.
After withdrawing from the Townlong Steppes, the Mogu headed south toward the Dread Wastes. Mogu General Iron Qon led the ground forces, while Shan Bu commanded the cloud serpent air force.
Taran Zhu, leader of the Shado-Pan, rode his cloud serpent and watched the departing Mogu. For a moment, he did not know what to say. He had worried that the Mogu might be deceiving them and laying a trap, but it turned out he had overthought it.
With Lei Shen at their helm, the Mogu could fight the Mantid at the height of their power. Now, after the bloody battle at the Gate of the Setting Sun and the loss of over a million of their kin, the Mantid were no match for the Mogu.
The Mogu chose to land on a large island at the southern end of the Dread Wastes. The moment they landed, Iron Qon led the Mogu army in massacring every Mantid in Zan'vess, terrifying the Mantid with ruthless force.
The Mantid, who had originally pulled back, could no longer remain still after their ancient foes, the Mogu, appeared. An overwhelming Mantid army emerged once more and launched an assault before the Mogu camp had even been completed.
That assault inflicted grievous losses on the Mogu. Of the fifty thousand Shan'ze Clan Mogu in the vanguard, fewer than three thousand survived. However, there were even more Mantid corpses.
