Well, it's difficult to say who owned a 'Decadence After Dark' novel without more context. It might have been owned by a fan of the author. If the novel is a part of a series, it could be owned by those who are following the whole series. Maybe it was owned by a person who was recommended this novel by a friend and decided to buy it.
One main theme is often the exploration of the darker side of human nature. This could include things like excessive desires, be it for power, pleasure or wealth.
One could be 'The Picture of Dorian Gray'. It has elements of moral decadence and a certain allure in the darker aspects of human nature. The story follows Dorian Gray, a young man who remains beautiful while his portrait ages and reflects his immoral actions.
Dark Horse Comics and Marvel are distinct entities. Marvel has its own roster of characters and storylines, and Dark Horse has developed its own unique properties and franchises over the years. So, they have no ownership connection.
Some of Dark Horse Comics' most popular titles are creator-owned. Creators have found a platform with Dark Horse to bring their unique ideas to life and retain ownership rights. However, not all of their comics are creator-owned; it varies by series.
😋I recommend the following novel to you:
"Rebirth: The Road to Realizing Dreams": A decadent person is reborn. He hopes that his family will be healthy and happy in this life. He hopes to realize his dream in his previous life and have a childhood relationship.
"The Strongest Counterattack System": The decadent youth's goal is to counterattack. He will restart the third year of high school with the Strongest Counterattack System and realize the counterattack of the weak.
"Thirty years of planting trees, I'll explode stars with one punch": Decadent watermelons return to the peak of life, planting trees has merit, and exploding stars with one punch has the path to becoming strong.
I hope you like this fairy's recommendation. Muah ~😗
