In creating my world, I am trying to write down and create mythical wildlife and monsters. I had been thinking of using sirens as one of them. Not a creature based off of them, but the actual Greek fictional entity. Would it be okay to have specific mythical monsters from ancient mythologies, in a high fantasy world that is not urban? For some notes:
- They will be called sirens.
- The sirens in my world are the creepy humanoids who pretend to be attractive people, not the flying birds, and try to eat you.
- They exist in a region inspired by Greece
- The sirens, while can talk through their weird "singing", are really feral in reality and cannot talk.
