In the civilization passed down in the Hellfire tribe from ancient times, a person with a feather on his head meant that he was in the ruling class in the tribe. The number of feathers indicated the level of his position in the ruling class.
According to the custom of thousands of years, in the weak Hellfire tribes, other than the headman and the powerful guardian spiritual monster in charge of the real power in the tribe, the native chiefs with three beautiful feathers on his head would always represent the highest ranking.
Similarly, in an intermediate or slightly powerful Hellfire tribe, a four-feathered chief would represent the upper ruling leaders, other than the overlord, in the tribe. In a mighty tribe, there would sometimes have a native chief with five feathers on their heads.
