In 'Arabian Nights and Days: A Novel', there are probably a variety of main characters. There could be a young hero or heroine on a journey of self - discovery. Maybe a wise old man or woman who imparts important knowledge. And also, characters representing the power structure like a sultan or a noble. These characters would interact with each other, with their fates intertwined in the complex world of Arabian settings, with its blend of magic and reality. Their personalities and actions would drive the plot forward, whether it's during the mysterious nights or the more down - to - earth days.
I'm not entirely sure as I haven't read it in great detail, but likely there are characters inspired by the traditional Arabian Nights' figures such as sultans, genies, and clever commoners.
