what is the symbol for the ancestor rock and the talking feather

Edwin instructs Cole to carry this "ancestor rock" up a hill on the island each day, in honor of his own ancestors and the unity of all human life. When he reaches the top, he is supposed to role the rock back down the hill, symbolizing his anger.

Cole's Circle Justice used a feather as their talking stick. The feather was passed around, and only the person who possessed it was allowed to talk.

Respect others as much as yourself. When the feather comes to you, speak only if you wish to. This circle carries only two obligations—honesty and respect.”
