The ruling Demons in Celestial Stone Kingdom were the Earth-Shaking Hog Dragons, famed for their thick hides and tough flesh. The kingdom was home to a great number of Pig Demons.
Pig Demons and Wolf Demons are natural enemies. Despite the Demon Court's repeated attempts to mediate, relations between Celestial Chime Kingdom and Yingyue Kingdom remained extremely tense. The Demon Wolves from Yingyue Kingdom frequently invaded Celestial Chime Kingdom to prey on its Demon People.
For this reason, Celestial Chime Kingdom stationed a Demon Army permanently on its border with Yingyue Kingdom to guard against Demon Wolf incursions.
Although the Rescue Army had two Flying Boats patrolling back and forth along the Yingyue Kingdom's border, hunting down Demons who tried to flee east, the Demon Wolves were, after all, more familiar with the local geography. Quite a few slipped through the net.
