Sorry, I'm not aware of the author of this novel. There are so many novels out there, and this one isn't widely known to me. Maybe check with some book enthusiasts or specialized book - related forums.
I'm not sure specifically as I haven't read it. But generally, it could be about a night filled with illumination in a metaphorical or literal sense. Maybe it's about events that happen during a night when there is a special kind of light, like a spiritual illumination or an important discovery that lights up the story like a physical illumination.
I'm not sure which novel you're referring to. The Illumination Realm was a common concept in novels. It usually referred to the cognitive level and state of the world or characters in the novel. It was often described as a transparent, visual, and relatively objective realm that allowed people to directly perceive the world and content of the work through their senses. The levels of the Illumination Realm were usually related to the theme and worldview of the work. Different stories might have different levels of the Illumination Realm.
