Nice post about these legends @paperbackwriter.
Edit: Suggestions, try to separate your paragraphs a bit more. Right now they look a bit like a wall of text and it makes reading a bit more challenging then it rightfully should be. Maybe Add a heading or two in there when you switch topics ( just for ease of following your direction, not that your writing is unclear).
