I'm not sure as I haven't read the novel. But usually, in a novel like this, there might be a protagonist who is likely to be the one exploring the 'dark corners' either literally or metaphorically.
Since we don't have much information about the novel, it's hard to say exactly. However, it's possible that there could be a detective - like character if it's a mystery novel. This character would be trying to uncover the secrets in the 'dark corners'. There might also be a character who has a lot to hide, whose secrets are related to these 'dark corners' in some way.
I'm not sure specifically as it depends on the particular story in the novel. But usually, there are investigators or people who stumble upon the dark secrets of the Cthulhu Mythos.
It could also center around a sense of unease or danger. The 'dark corners' might be literal or metaphorical places in the story where bad things happen or secrets are kept. For example, it could be an old, abandoned building with hidden rooms (literal dark corners) that hold the key to a mystery in the novel, or it could be the hidden thoughts and motives of the characters (metaphorical dark corners).
Isolation is a common theme. Characters in 'dark corners novels' are often alone, either physically or emotionally. For example, in 'The Catcher in the Rye', Holden Caulfield is in his own 'dark corner' feeling alienated from the world around him.
I'm not sure as I haven't read the specific 'in the dark novel'. But usually in such novels, there could be a protagonist who is often at the center of the story, facing the challenges presented by the dark elements. There might also be an antagonist, someone or something that is causing the problems or the 'darkness' in the protagonist's life.
One 'dark corners novel' that might be interesting is 'The Strange Case of Dr. Jekyll and Mr. Hyde'. It delves into the duality of human nature, with the dark side personified in Mr. Hyde. The story unfolds in the shadowy corners of Victorian society, exploring themes of morality and the hidden parts of the self.
The key features often include a sense of cosmic horror. It likely has complex and mysterious characters, as is typical in Call of Cthulhu stories. The setting is probably dark and foreboding, filled with elements that make the reader feel unease and a sense of the unknown.
I don't know exactly who the main characters are in the 'dark paradise novel'. However, it's common in such novels to have a hero - type character who is on a journey of discovery in this strange and dark place. There could also be supporting characters like a wise old figure who gives advice, or a sidekick who helps the main character in their adventures.
There might be a protagonist, perhaps a skilled navigator in the 'Dark Voyager Novel'. There could also be supporting characters like a wise old mentor who gives advice to the voyager before the journey or a fellow traveler who joins the main character along the way and has a different perspective that adds to the story.
Since I haven't read it, I can't say for sure. But they could be the so - called 'dark ones' themselves, perhaps a leader among them or a group of outcasts who are central to the story.
I'm sorry, without having read the novel, I can't say for sure who the main characters are. They could be two young lovers, or perhaps people from different social backgrounds.
