I did a lot of research into Victorian design and typefaces for the cover. Some of the look of that area is really great, but nothing felt quite right for this book. For one thing, the book was about two beings who don't really belong in the era. So going with a straight mimicry of Victorian design didn't seem appropriate. For the logo, I eventually went with an elegant typeface with some distinctive visual flair. I manipulated it slightly and adorned it with some flourishes.
