Some legends are too useful to become epic history. If people still use a story to find the safe rocks, avoid the marsh, or know which harbour stone means trouble, it probably belongs in the category of local knowledge, not grand myth.

And local knowledge is usually messy. Half-remembered. Told wrong on purpose, or just told badly enough that it survives by being practical.

That feels more interesting to me than a perfectly preserved tale. A legend that people quote with a shrug and still trust with their lives has more weight than one that only works in a book.
