The Bahru Family has been on the throne of the Naviri Isles for generations.
The chiefs are chosen by duelling, and anyone who is against the chosen chief can either challenge him or move from the island.
The Bahru are known for their superior combat skills and their kin is raised with fighting techniques from a very young age. They take a lot of pride in their position and openly boast about it by either challenging others to matches with nothing to win except respect or by telling someone to "join my class" in the Bahru fighting style to teach them a lesson.
Especially the current chief, Jenera Bahru, always lets his daughter's taunts slide even though his people seem fed up with her boasting to everyone and being cruel to those not up to her challenges.
Jenera's daughter, Bhlin, has gotten it into her head that she is basically chief already because nobody wants to fight her now, so why should they later. This, along with her hotheadedness and brash attitude, has gotten a lot of the younger Dragonborn to leave for Fui Ley or somewhere else in the world to go find their own path in life, and many have chosen a life without fighting as a result.
