Here's Benj. I know personality probably doesn't matter, but I'll say it anyways. He was the first male leader of his tribe; females had led for generations, but his mother did not give birth to a female heir, so he was made leader and told to make one of his daughters the leader next. (One other male has been leader,many generations later, for the same reasons.) He was known as a merciless killer, killing any tribemember that was not useful. However, he wasn't mean to the useful tribemembers (he wasn't ecspecially kind, just okay).
And this is Madame (ignore name in picture; also, she's an adult). She came to the tribe as a wanderer, and stayed pretty mysterious-- she never revealed any of her past. She's curious and made a few friends in her new tribe.
