Natsilane (/noʊtsaɪˈklɑːneɪ/ noht-sy-KLAH-nay)[1] is the human hero of the "Blackfish" creation myth, one of the Tlingit and Haida stories about how the various supernatural animal species from the Tlingit culture of the American Northwest coast were created. These stories follow an almost dreamtime-like description of humans and other animal species living completely harmoniously. The animals are depicted as demi-gods, and are always referred to as proper singular nouns (for instance, "Raccoon" and "Raven"). There are other similar stories including how Raccoon got the rings on his tail and why Puma hides in the forest so much.
Blackfish is arguably the most important creature in Haida culture. Blackfish is also highly revered in Tlingit culture because of his apparent affinity with humans. He represents an extremely powerful force of nature, deadly and terrifying to every creature except man, whom he is said to look after. The story describes why this is so. There are many variations to the tale, some considerably more brutal than others, and the exact details vary widely according to the storyteller, but the main theme of the story is always the same.
