The conflicts within the Demon Clans mainly stem from the relationships in the food chain.
For example, the Eagle Clan and the Snake Clan, they just can't get along, being part of the same Demon Clans, they are still in constant conflict.
However, as the Demon Clans developed, they also established their own unique rules.
Hunters, within their clan's territory, need not be responsible for any prey they catch, but they are only allowed to operate within their own clan.
Take the Eagle Clan for example. Members of the Eagle Clan are not allowed to venture into the territories of other prey species, and conversely, if a member of a prey species enters the Eagle Clan territory, they are automatically considered fair game to be hunted, regardless of life or death.
It was only when She Shishi found herself in the Eagle Clan's territory that she realized her situation was no better than if she were in the Snake Clan's domain.
