Describe what it means for an Eboe man to be designated as "Embrenche" in The Interesting Narrative and Other Writings?

Being designated as an "Embrenche" was an honor for Eboe men, and it meant that they were a respected elder who helped to run the village. These men were marked by having a scar put on their forehead, which is interesting because it seems like branding, which I always associate with American slavery. Ironically, in the case of Embrenche, the scarring represents being higher in society rather than being lower. It also suggests that the position was permanent.
