FYI: Kapu, or sacred laws, were of utmost importance to Hawaiian culture and the breaking of kapu had its consequences, including death. If one were to break kapu, their only chance for survival was to evade his pursuers and make it to a puuhonua, or a sacred place of refuge. Once there, a ceremony of absolution would take place and the one who broke kapu would be able to return to society.
