How was the Chinook society set up?

The Chinook society was organized around a stratified social structure that included nobles, commoners, and slaves. They lived in large, plank houses along the Pacific Northwest coast, relying heavily on fishing, particularly salmon, for sustenance. Their economy was bolstered by trade, with the Chinook language serving as a lingua franca among various tribes. Spiritual beliefs were integral to their culture, with a strong emphasis on nature and the supernatural.
