The hydra god mastered the mighty power of reproduction. Following the tracks of the hydra god, they sought to replicate the sacred path of the deity, which included, but was not limited to:
Forcibly with all major races*, whether female, old, or even little boys, whether alive or not didn't matter.
When put that way, even a priest would feel compelled to pat the head of kneeling boy and acclaim his understanding.
As for what could trigger such murderous intent among players...
The seed of the issue was the attitude of the desert serpentfolk towards players, roughly:
"I am a descendant of the hydra god, master of the world, gods are our puppets, while you, as the children of this land, rounded up, are equal to our dogs, no problem, right?"
It wasn't just their foul mouths that discomforted players. In such a large population of players, there were always some who, even in the game, would see themselves as others' dogs.
