What concepts in the Sawi culture intrigued / reviled / saddened / angered / surprised you?

I found the concept of the peace child very surprising. When I first read the book, the idea of cannibalism was such a shock to me that I felt like the peace child would have no effect at all. But as the story advanced, I realized that people actually changed with the peace child. By the giving the child up, people actually ceased quarreling and peace came to the people. Even when a fight was about to rise up because of the pig, by the mention of the peace child, the fight ended quickly. I was shocked that such a system was implemented in such a brute and savage culture. I think that the peace child acted as our saviour, Jesus and brought peace to the people there.
