I read this book nearly 2 decades ago, I Am Dracula which blended various supernatural elements to show how Vlad the Impaler actually became the King of Vampires. He apparently was "soul mated" to a mystic gypsie girl, Zigane, in Walachia, finding this out when she astral projected to him as a boy. He then endured hardships growing up very much in line with the historical Vlad before she, now a full fledged witch, found him and lead him on the path. There were a lot of supernatural references and liberties taken; Dracula was made a Vampire by Zigane , who was made a Vampire by some large batwinged creature that came out of a lake, and they got further mystical powers by serving the devil, including a "sun sheld spell" which is why Dracula could exist in the sunlight, evenn being a vampire.
Can anyone clearly define all the supernatural creatures in the book, as well as where they hail from in terms of their mythology [I'm guessing the Wing serpant was an interpretation of Quetzalcoatl, the Mayan God, but I'm lost on the others]. Also, is the I Am Frankenstien book made by the same author?
