You misunderstand - it sounds like an attempt by the author to be "cute." As in, "overly linguistically clever." It makes the race, for me, seem silly, simply because of the name. It is also a name with some literary baggage, thus a good reason to avoid unless you like the baggage. Daevil is better in my opinion, though I think you could do better yet if you tried. Some suggestions....
