A beta reader of mine is advising me to be extremely subtle with my use of.....well let me tell you what I'm doing and what he's recommending and you'll see what I'm talking about: I have a race called cait sidhe in the book based on the ACTUAL cait sidhe with physical differences to the creatures but otherwise functioning the same. I also use names out of Irish lore, the names of heroes and locations, and the story CAN be interpreted to follow the actual legends. My beta reader is recommending not to use actual names like cait sidhe or the names of the mythical heroes because people who know the actual legends and creatures will be put off if they don't match exactly or just in general have a distaste to finding references to actual mythology. His primary concern though was that people who know the actual legends would be put off by the thing not matching. He recommends I rename the cait sidhe race and just let readers connect the dots and try to get there on their own. One example he gave was when he read a book that contained a character called king Leonidas (based on the actual king Leonidas), it turned him off. Does he have a point on this matter or is it fine to continue on the path I've taken?
