Locally among the Tahltan people, their customs and livelihoods varied widely as they were often widely separated and would have to endure varying conditions depending on their locality. In Tahltan culture it was believed that some of their ancestors had knowledge that others did not from times before a great flood. Some of these ancestors used that knowledge for the good of the people, while others used it for evil and to the disadvantage of others. Raven is considered to be the protagonist hero against these evil ancestors.
