What is the author's style in No. 44, The Mysterious Stranger by Mark Twain?

"The Mysterious Stranger" is a fantastical tale, meaning that it includes elements of magic and supernatural occurrences. By setting his story in a remote time and place, and by infusing it with elements of magic and fantasy, Twain is able to explore themes of dreams and the imagination without limiting himself to the requirements of realist fiction. Through the fantastical character of Number 44, Twain ultimately postulates that the realm of dreams, fantasy, and the imagination are more relevant to human experience than are the experiences we associate with concrete, physical reality.
